(YPI)is the only project participant. On February 17,2004,David Lockard of AEA/REG and Steve Stassel of AE&E performed a site investigation to determine community energy related needs in Yakutat.On July 14,2004,Kris Noonan of AEA/REG and Clois Versyp of AE&E performed a follow-up site investigation to gather field data relating to the potentialenergyprojects. The YPI power plant was constructed in the mid-1960s.The power plant is old and experiences water problems from poor site drainage and a leaky roof.The power plant has four Caterpillar generators.Unit 1 is a CAT 3412 rated 330 kW. Unit 2 is a 3512B rated 880 kW.Unit 3 is CAT 3508B rated 600 kW.Unit 4is a CAT 3516 DITA rated 1100 kW.Unit 1 is undersized and beyond its useful life and will be replaced with a new Caterpillar model 3516B generator,funded by a separate project.Units 2,3,&4 will be relocated to the new powerhouse. The existing switchgear contains a combination of oil and air magnetic circuit breakers.Replacement parts for the air breakers are limited,and parts for the oil breakers are no longer available.The new power plant will be equipped with state of the art automatic start/stop and paralleling switchgear for improved fueleconomyandplantreliability. The existing power plant fuel storage system does not comply with current state and federal regulations for above ground fuel tanks.A new code compliant fuel system consisting of a 30,000 gallon double wall bulk tank and a new 3,000 gallon double wall day tank will be provided at the new plant.The new tanks will be equipped to comply with EPA requirements for alternative secondary containment systems.The bulk tank will be filled by fuel truck,or from a new fill pipeline from the Delta Western fuel facility. The power plant provides recovered heat to school buildings and power plant facilities.Recovered heat is the sole source of heat for the school facilities,saving approximately 30,000 gallons of heating fuel per year.Upgrades to the existing heat recovery system include new variable speed pumps to reduce pumping energy,new heat exchangers at the power plant and voc-ed building,heat exchanger plate pack replacement at the elementary and high school,and connection of the new power plant to the existing arctic pipe system. Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering The existing electric distribution is in poor condition.The original overhead system was constructed in the 1960s.The majority of the poles are beyond their useful lives,many of the crossarms are too short,and conductor clearances in some areas do not meet code requirements.The existing 5 kV underground distribution cable is non-jacketed and is experiencing neutral conductor corrosion. There are three existing electrical distribution feeders rated 2400/4160 volt grounded wye,2400-volt delta,and 7.2/12.47kV grounded wye.The three separate feeder voltages do not support feeder redundancy and cannot be connected together to provide backup for service reliability.The existing electrical distribution system voltage will be upgraded to 7.2/12.47 kV and the overhead portion of the system will be converted to underground.The existing 5kV underground cables will be replaced with new 15 kV rated cable.The distribution system upgrade has been broken into three phases to accommodate partial funding as available. The proposed fill pipeline will provide diesel fuel directly from the Delta Western tank farm to the new bulk tank at the power plant.The new pipeline will reduce the risk of spills associated with truck transfer and provide more efficient delivery of nearly a half-million gallons per year of diesel fuel to the power plant. To the maximum extent possible,construction of the new power plant building and installation of the underground distribution system should be performed in the spring and summer to take advantage of the less seasonally rainy weather.The proposed project schedule for the power plant calls for design and permitting to begin in the fall with final completion approximately 20 months after the start of design work.The proposed schedule for the distribution upgrades calls for Phase 1 to be completed in two spring/summer seasons and Phases 2 and 3 to each take an additional spring/summer season.All construction scheduling is contingent upon available funding. Separate estimates have been prepared for the Power Plant Upgrade (including Bulk Fuel and Heat Recovery)each phase of the Distribution System Upgrade, and the Fuel Transfer Pipeline Installation.The estimated total project cost including all design,supervision,inspection,permitting,and a 15%contingency for each component is: e $2,638,033 Power Plant Upgrade e $2,848,047 Distribution System Upgrade Phase 1 e $2,109,236 Distribution System Upgrade Phase 2 e §$728,328 Distribution System Upgrade Phase 3 e $5,685,611 Distribution System Total e $281,973 Fuel Transfer Pipeline Installation e $8,605,617 Grand Total All Improvements The total installed generation capacity of the new power plant is 4,115 kW.The unit cost of the Power Plant Upgrade is $641/kW which is within the Denali Commission benchmark cost range of $1,250 to $500 per installed kW for greater than 1,200kW capacity power plants.

Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Enerqy and Engineering 1.0 INTRODUCTION This report has been prepared by Alaska Energy and Engineering,Inc.(AE&E) for the Alaska Energy Authority/Rural Energy Group (AEA/REG).The purpose of this study is to provide a conceptual design and construction cost estimate for energy infrastructure improvements in the community of Yakutat.The components of the project include: Power Plant Replacement. Power Plant Fuel System Upgrade. Heat Recovery System Upgrade Power Distribution Upgrade Fuel Transfer Pipeline from Delta Western. All projects components are dependent on available funding.Yakutat Power, Inc.(YPI)is the only project participant. 1.1 Program Overview The Alaska Energy Authority (AEA),Rural Energy Group is pursuing grant funds to upgrade rural energy systems.Following is a brief outline of the program: e Most of the funds are Federal and provided through the Denali Commission (DC).Additional funding may be available from other State and Federal agencies. e A comprehensive community plan is required by the Denali Commission starting with the FY2005 funding cycle.Resources and sample plans are available through the DC website (http:/Awww.denali.gov/)and by contacting Michelle Anderson at (907)271-1542. e In order to receive grant funds,each community must demonstrate that the proposed facility will be sustainable.In most cases this is accomplished by accepting a business plan.A business plan describes who will own the facility,and how it will be operated,maintained and replaced.A business plan is not expected to be required for this project as the electric utility is self- sustaining.” e New energy projects are funded,designed,and constructed in three phases: Phase 1,Conceptual Design;Phase 2,Design Completion;and Phase 3, Construction. e During Phase 1,Conceptual Design,staff from AEA will visit a community, discuss the program,and work with residents and the local government to select sites for the new facilities. e At the completion of Phase 1 Conceptual Design,the community will be requested to review and approve the location,capacity,and basic configuration of the facilities as well as a draft business plan (if required). e During Phase 2,Design Completion,the design for the new energy projects will be completed.An environmental assessment will be prepared and site contro!documented. Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering e The community will be requested to provide "in kind”contributions to the project.Examples of "in kind”contributions on prior Denali Commission funded projects include providing the land for the project,and free use of local heavy equipment.The grant funds typically pay for equipment fuel, maintenance,and repairs of equipment during construction. e Projects may include local hire and construction trade training programs, subject to Denali Commission funding. e Ineligible Projects:Funding is not available through AEA for operation & maintenance costs or residential upgrades. e Training Available:AEA has several training programs available for communities. 1.2 Community Description Yakutat is located along the Gulf of Alaska,225 miles northwest of Juneau and 220 miles southeast of Cordova.It is at the mouth of Yakutat Bay,and lies at approximately 59.33°North Latitude,139.44°West Longitude (Sec.30,T027S, RO34E,Copper River Meridian).The area encompasses 7,650 sq.miles of land and 1,808 square miles of water.Yakutat has a maritime climate characterized by relatively mild,often rainy weather.Summer temperatures range from 42°F to 60°F,and winter temperatures range from 17°F to 39°F.Yakutat receives some of the heaviest precipitation in the state,averaging 132 inches,including 219 inches of snowfall.The population was estimated at 619 residents in 2004. Local governments include the City and Borough of Yakutat and the Yakutat Tlingit Tribe Traditional Council.Yakutat is located in the Juneau Recording District and the Yakutat City School District. 1.3 Site Investigation On February 17,2004,David Lockard AEA/REG and Steve Stassel of AE&EperformedasiteinvestigationinYakutat.The primary purpose of this site visit was to provide information to the community regarding the AEA programs and toobtainreconnaissancelevelinformationtoidentifycommunityenergyrelated needs. On July 14,2004 a second site investigation was performed by Kris Noonan of AEA/REG and Clois Versyp of AE&E.Additional field data was gathered on existing community power generation and distribution systems as well as the existing heat recovery system. Prior to the field investigations,available information was obtained and analyzed, including aerial photographs,community profile,survey plats,PCE data,Corps of Engineers wetlands and flood information,and other relevant data.During the initial field investigation,Yakutat Power Inc.(YPI)electrical distribution system and power generation drawings were obtained.Additional information and input was obtained from the following individuals: Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering e Mr.Steve Henry,Manager,City and Borough of Yakutat (907)784-3323 e Mr.Larry Powell,President,Yakutat Power,Inc.(907)784-3323 e Mr.Scott Newlun,Manager,Yakutat Power,Inc.(907)784-3242 e Mr.Ron Bueller,Plant Operator,Yakutat Power,Inc.(907)784-3323 e Mr.Kirk Payne,Operations Manager,Delta Western 276-2688 e Mr.Bob Simpson,Alaska Road Boring Company 344-6895 e Alaska Marine Lines,Seattle (206)764-8346 1.4 Code Analysis &Deficiencies The following is a summary of existing power plant,electric distribution,and fuel system code analysis and deficiencies observed during the site investigations. Power Plant: e The power plant,cable trays,and switchgear occasionally experience flooding from snow melt and a leaking roof posing life/health/safety concerns for plant personnel. Distribution System: e The majority of the existing power poles are beyond their useful lives,and some appear to be in danger of failing. e Many of the pole cross arms are too short.Conductor clearances in some areas do not meet the National Electrical Safety Code requirements. e The existing 5kV underground cable is experiencing neutral corrosion. Fuel Tank System: e Improper Secondary Containment (Diking)-The existing storage tanks are self-diked,but are not equipped with the necessary overfill prevention devices to meet Fire Code and EPA requirements for alternative secondary containment. e Improper Security -The tanks are accessible to the general public with no security fencing.This presents a hazard to the community as well as increasing the chance of a spill or fire due to vandalism or theft.Additionally, none of the valves were locked further increasing the potential of a spill due to vandalism or theft. e Improper Valves -The main withdrawal valve on the bulk tank was leaking and cannot be repaired or replaced without removing the tank from service. The concept design for the power system upgrade project has been prepared to meet current code and regulatory requirements,which include: The 2003 Edition of the International Building Code (IBC). The 2003 Edition of the International Fire Code (IFC). The 2002 Edition of the National Electrical Code (NEC). The 2002 Edition of the National Electrical Safety Code (NESC). Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering 2.0 EXISTING FACILITIES The existing community energy infrastructure was evaluated to determine specific needs and deficiencies.The power plant,distribution system,fuel storage,and heat recovery system were visually examined to determine suitability for re-use.The following paragraphs summarize findings for the community. 2.1 Power Plant The original YP!power plant building is believed to have been constructed during the mid-1960s.The power plant is located on tract "A”of the South Addition Subdivision near the southeast corner of the Forest Highway No.10 and the Airport Road.The power plant is housed in a combination utility building consisting of four separate structures:The original building houses the generating equipment and switchgear;the operators and managers office is in an addition on the south side of the original building;a covered parking area is on the north side of the original building;and a newer addition to the east houses the line trucks and a fire engine. The original building is a 60'Lx40'W concrete slab on grade structure constructed of 3x6”wood girts and purlins with steel lattice type tapered trusses and exterior metal siding.The building is not insulated nor is there any interior sheeting.The columns on the north side covered parking area are rusted at the base to the point of near failure.The exterior of the original building is in poor condition with numerous holes,and has been badly dented from snow and snow removal vehicles hitting the building.The roof is ventilated with turbine vents and the wall separating the power plant and the line truck area is open.Most of the exposed building material in the original building is plywood. The plant office and manager's office is a 64'Lx24'W metal sided,pre- engineered steel frame structure.The line truck addition is a 64'Lx40'W metal sided,un-insulated pre-engineered steel frame structure.Both are slab-on- grade construction.Whereas the original building and north addition are inrelativelypoorcondition,the office and line truck additions appear to be in goodcondition. The power plant experiences water problems due to poor surface drainage as well as a leaky roof.During the winter,when the ground is frozen,surface water has flooded into the powerhouse and filled the cable trenches.There have also been occurrences where the switchgear has been surrounded by water,and water leaking through the roof has dripped onto the switchgear.This combination of water and electricity creates a life/health/safety concern for plant personnel. The noise level around the power plant has been of concern due to the close proximity of the elementary and high schools located to the north across Forrest Highway No.10.The existing air intake and exhaust system consists of un- ducted air louvers,which provide no sound attenuation.Also,fan driven radiators for the engine cooling system are located in an open,covered area on Yakutat Rural Power System Upgrade Project -May 24,2005 Concept Desiqn Report Alaska Energy and Engineering the north side of the power plant,which contributes to the overall noise level transmitted to the school area. There have also been complaints of exhaust odors at the elementary and high school.The prevailing winds for the Yakutat area are from the south and exhaust from the power plant is frequently blown toward the schools. The power plant contains four Caterpillar generators operating at 4160 volts. Unit 1 is a CAT 3412 with a prime capacity of 330 kW at 1200 RPM.It was installed in the mid-1980's and currently has approximately 42,248 total engine hours.The last major overhaul was performed in December 1997 at 34,521 hours and it is due for another major overhaul. Unit 2 is a CAT 3512B with a prime capacity of 880 kW at 1200 RPM.The engine was purchased new in November 1999 and was installed on an existing under-sized generator end.The engine is capable of providing 1050 kW at 1200 RPM.Current engine runtime is 21,041 total hours.A top end rebuild was performed in March 2002 at 9,696 hours.It is scheduled for a major overhaul in the near future. Unit 3 is a CAT 3508B rated 600 kW at 1200 RPM.It was purchased new in November 1999 and has 3,886 total engine hours.It is in like-new condition. Unit 4 is a CAT 3516 DITA rated 1100 kW at 1200 RPM.It was purchased new in 1993 and has 68,688 total engine hours.The last major overhaul was performed in March 2000 at 48,525 hours.A top end rebuild was performed in February 2003 at 64,608 hours.The next major overhaul is scheduled for 2006. With continued proper scheduled maintenance and overhauls,Units 2,3,and 4 should each provide in excess of 100,000 total operating hours and can be reused in the new power plant.Unit 1 (CAT 3412)should be replaced with a larger,more fuel efficient genset to meet the electric power needs of the community. Engine cooling is with four separate radiators.Unit 1 has a dedicated radiatorlocatedinsidethepowerplantabovetheengineinamezzanine.level area.Units 2 and 4 each have dedicated remote radiators located on the outside of the north side of the power plant.Unit 3 is equipped with a skid mounted radiator. Units 2 and 4 provide jacket water heat to the plate heat exchanger located in the fan room.Recovered heat is used to heat the power plant,utility manager's residence,and three school buildings. The electric utility has recently been awarded a combination grant/loan for a new CAT 3516B genset.The new genset will replace the existing undersized and inefficient Unit 1 (CAT 3412). 2.2 Fuel Storage Delta Western provides storage,distribution,dispensing,and retail sales for virtually all diesel fuel and gasoline for the community of Yakutat.Delta Western requested exclusion from this report based on national security concerns,but did provide the following information:The tank farm was renovated in 1993 and has storage capacity of less than 1 million gallons of gasoline and diesel fuel.The 5 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering U.S.Coast Guard has recently shut down the City-owned dock,which has historically been used for receiving fuel barge deliveries and for fueling marine craft.The City and Borough of Yakutat is working to replace the condemned dock with a new facility.Since the facility was not assessed,potential upgrades to the Delta Western storage facility were not evaluated.Additionally,Denali Commission policies do not typically provide funding for projects directly to for- profit entities. Yakutat Power purchases fuel from Delta Western,which is trucked and delivered to the power plant on an as-needed basis.It was reported that Delta Western delivers an average of 7,800 gallons of diesel fuel per week to Yakutat Power. The existing power plant fuel storage system consists of two fuel storage tanks. The bulk tank is a 20,000-gallon self-diked double wall,horizontal,skid mounted, welded steel tank set on timbers.It is equipped with top-mounted appurtenances including normal vent,manholes with spring-loaded bolts for primary tank and interstitial space emergency venting,and a level gauge.The tank is filled via a 2”fuel-rated hose with dry-break adapter connected to a 2” welded steel pipe,steel ball valve and a top mounted fill limiter.Fuel is transferred to the day tank from a 3”steel valve bottom withdrawal,via 2”welded steel piping and transfer pumps located in an adjacent pump box. The day tank is a 3,000-gallon self-diked double wall,horizontal,skid mounted, welded steel tank set on heavy timbers on an elevated earthen pad.It is equipped with top-mounted appurtenances including normal vent,manholes with spring-loaded bolts for primary tank and interstitial space emergency venting, and a level gauge.The top mounted fill connection has a fill limiter and liquid controls type meter.A welded steel supply line,routed from a bottom mounted 2” steel ball valve,provides fuel to the diesel engines,and a welded steel return lineisconnectedtothetopofthedaytank. The fuel storage area is illuminated by utility and building lights,but is not fencedandtherewerenolocksonthetankandpipingvalves.The fill valve on the bulktankwasleakingat.the time of the site visit,the fuel level sensor was reportedly not operational,and neither tank was equipped to comply with EPA's requirements for secondary alternative containment tanks.Warning signs were posted,but the tanks were not labeled in accordance with Fire Code requirements.The existing fuel storage system does not comply with current state and federal regulations for above ground fuel tanks,is antiquated and should be replaced. 2.3 Heat Recovery System The YPI heat recovery system was constructed in 1991 and provides recovered heat to three school buildings and to the power plant facilities.The heat recovery system at the power plant consists of a 6-port plate and frame heat exchanger,arctic pipe loop expansion tank,base-mount circulating pumps,and thermometers and pressure gauges.The 6-port heat exchanger captures heat from gensets 2 &4.Each genset is piped through separate chambers of the heat exchanger so that the cooling system fluids do not mix.The recovered heat 6 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering is transferred through 3”arctic pipe to the elementary school,voc-ed building and high school (heat is also provided to the utility managers house).The recovered heat is transferred to the elementary and high school heating system via plate and frame heat exchangers located in the respective boiler rooms.The vocational education shop does not have a heat exchanger and is connected directly to the arctic piping system.The elementary and high school boilers have not been operational since the heat recovery system was installed and all building heat is supplied from the heat recovery system. 2.4 Power Distribution The existing switchgear consists of a 5 kV lineup with Allis-Chalmers oil circuit breakers for Units 1 through 3 and four feeders,and an FPE air magnetic circuit breaker for unit 4.The Allis-Chalmers switchgear was reportedly surplus from the original FAA equipment installed at the airport and dates from the 1950s or 1960's.Unit 4's air magnetic circuit breaker was installed in 1993 and is previously used equipment,as air magnetic circuit breakers have not been manufactured since the mid-1980s.Replacement parts for the FPE breaker are limited and parts for the Allis-Chalmers breakers are no longer available; therefore,the existing switchgear needs to be replaced entirely. There are three feeders (feeders 1-3)that power the community and one (feeder 4)that provides power for power plant station service: e Feeder 1 has a 1500 kVA pad-mounted step-up transformer connected 4160V delta on the plant side with a dual primary switch for connection at either 2400/4160V or 7200/12470V on the City side.Feeder 1 is connected 4160V wye and feeds the airport,Glacier Bear,YKI Seafoods,and the ASHA housing and West Addition subdivisions. e Feeder 2 has three,333 kVA,single-phase pole mounted step-up transformers connected 4160V ungrounded wye on the plant side.Feeder 2 is connected 2400V delta and feeds the main town and range area and is in the poorest condition. e Feeder 3 has a 1500 kVA pad-mounted step-up transformer connected 4160V delta on the plant side and 7200/12470V wye on the City side. Feeder 3 is dedicated to the City cannery. e Feeder 4 has a 120/208-volt station service transformer located on top of the Feeder 4 switchgear section.480-volt station service power is also provided by a 75-kVA,oil-filled transformer located in the east addition. The three step-up transformer banks are located near the power plant adjacent to Forest Highway No.10.The three separate feeder voltages do not support feeder redundancy and there are no provisions for one feeder to provide backup power to another feeder.Therefore,a step-up transformer failure would result in a long-term power outage for that feeder.The existing step-up transformer banks for feeders #1 and #2 need to be replaced. The existing electric distribution system is primarily overhead with some underground cable.The overhead distribution system is in poor condition,with 7 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering the original system dating back to the early-1960s.The majority of the poles are beyond their useful lives,some of the poles appear to be in danger of failing, many of the cross arms are too short,and conductor clearances in some areas do not meet the National Electrical Safety Code requirements. Feeder 3 and the East and West Addition subdivisions have #2 AWG aluminum, 15 kV jacketed concentric neutral direct bury cable.The ASHA subdivision and airport utilize 5 kV direct buried cable.The 5 kV rated cable is primarily a non- jacketed,concentric neutral cable.The absence of an overall jacket exposes the concentric neutral directly to the soil.Much of the 5 kV underground cable is experiencing neutral corrosion,which could be a serious problem if the neutral conductor is compromised.The existing 5 kV underground system is a wye system with all single-phase transformers connected line-to-neutral.Voltage problems caused by the continued deterioration of the neutral conductor are expected to increase.If the 5kV cable neutral fails,the transformers on this portion of the distribution system will be inoperable. The existing electrical distribution system is antiquated,inefficient,potentially hazardous,subject to high operation and maintenance costs,and should be replaced with a new underground distribution system.The distribution system voltage should also be increased to 7200/12470V for all feeders for improved efficiency,reduced losses,improved VAR support,simplification of maintaining spare parts,and to allow one feeder to backup feed another in the event of a failure. 3.0 COMMUNITY POWER DEMAND Power consumption data was obtained from the Power Cost Equalization (PCE) program for 1999 through 2003,and from the electric utility.Copies are included in Appendix D.The following sections summarize findings for the power plant based on the available data. 3.1 Estimated Future Load Growth It is important to evaluate the impact of planned infrastructure improvement projects on an existing power generation system.New construction and other community improvements can adversely impact the adequacy of existing facilities.According to PCE data for Yakutat Power,the highest peak demand was approximately 1,800 kW and occurred September 2000.The lowest peak demand was 890 kW and occurred March 2003.Unlike most rural Alaska communities,peak electric loads in Yakutat occur between July and October, and are primarily associated with fish processing.Over the past several years fish processing operations have declined and peak loads have been on the order of 1500 kW.Daily plant loads vary between about 500 kW and 1000 kW during the non-fishing season (November to June). At present,there are few known near-term or future projects that would increase electrical consumption in Yakutat.The airport is undergoing a renovation including additional taxiway lighting.According to Rob Swanson,airport electrical contractor,there should be no net change in electric load at the airport due to the installation of lower wattage lighting.A new subdivision is currently in 8 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering the design stage and the additional peak load is estimated by YPI to be about 150 kW.For planning purposes,it is estimated that the community electric load will increase at a rate of 2%each year,in addition to the one-time load increase from the new subdivision.Based on this,the peak electric demand is estimated to increase approximately 350 kW over the next 5 years to about 1850 kW; whereas,the daily plant loads are expected to vary between about 700 kW and 1350 kW during the non-fishing season (November to June). Due to the magnitude of both the daily and annual load fluctuations,it is important to size the generation equipment to maximize fuel economy,yet provide sufficient redundancy so that two gensets have the capacity to carry the projected peak electric load. 3.2.Alternative Energy/Efficiency Improvements Currently a study is being performed under a grant from the Department of Energy to Sealaska Corporation to analyze the potential for renewable energy in Southeast Alaska,including the Yakutat area.Anemometers are installed near Chicago Harbor to monitor the potential for wind energy at that location. Monitors may be also installed in the Ankau Saltwater Estuary to determine the available energy obtainable from tidal activity.Preliminary results of the potential wind energy will not be available until sometime in the summer of 2005.The schedule for monitoring the energy available from tidal activity has not been established.No other potential alternative energy projects have been identified for Yakutat.At this time it appears that maximizing the utilization of recovered heat is the most viable alternative energy technology. 3.3 Power Plant Fuel Requirements Based on historic fuel delivery data and estimated future electric loads,it is proposed that the power plant fuel storage system provide a minimum of 14 days of fuel capacity based on the following: YAKUTAT POWER FUEL CONSUMPTION Current Average Daily Use for Peak Month in Gallons (1)1,600 Estimated Future Daily Use for Peak Month in Gallons (2)1,975 Current Peak Two Week Use in Gallons (1)22,400 Estimated Future Peak Two Week Use in Gallons (2)27,650 (1)From Yakutat Power FY04 PCE data. (2)Current peak plus average demand increase of 235 kW @ 15 kW-h sold/Gal. To meet the projected fuel needs a total of 33,000 gallons of gross tank capacity is proposed to be installed at the new power plant. Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Eneray and Engineering 4.0 SITE SELECTION &CONTROL Work for this project will be performed in three general areas:(1)The "Power Plant Site”;(2)The "Distribution System Rights of Ways”;and (3)The "Fuel Transfer Pipeline Right of Way”. 4.1 Power Plant Site Due to the dilapidated condition of the existing power plant building and poor area drainage,the existing powerhouse will be abandoned and a new powerhouse constructed on City property east of the existing power plant.The proposed site for the power plant has been previously cleared of trees and vegetation and is mostly level.Minor site work and grading will allow access to the new power plant and provide storage areas around the plant.The soils at the proposed site appear to be well drained gravels.The new power plant site is shown on the attached Overall Community Site Plan Sheet M1,and is adequate to meet code-required setbacks for the new fuel tanks and power plant building. 4.2 Distribution System and Fuel Transfer Pipeline Rights of Ways All work associated with the new distribution system will be within dedicated road rights of ways and easements owned by the City or State of Alaska.To the extent possible,road crossings will be laid out to minimize the impact to paved roads. The proposed fuel transfer pipeline will be routed below grade within existing road rights of ways and easements that are owned by the City or the State of Alaska.The pipeline will cross one paved road "Airport Road”,adjacent to the power plant site. 4.3 Site Control A Certificate to Plat was prepared by the Title Insurance Agency on November 10,2004.A copy of the Certificate to Plat is included in Appendix C.The existing power plant/tank farm is located on land owned by Yakutat Power,Inc. The proposed new power plant site is located on land owned by the City and Borough of Yakutat (City).To meet site control requirements for the project,the City will need to either lease or deed the new power plant site to Yakutat Power, Inc. The proposed underground electric lines will be within dedicated road rights of ways and easements.The City has jurisdiction over dedicated rights of way within the City boundaries that are not under the jurisdiction of the State of Alaska,Department of Transportation and Public Facilities (DOT&PF).Forest Highway No.10,Airport Road and Mallott Avenue (which is part of the Airport Road right of way)are all under DOT&PF jurisdiction.The utility will need to obtain permission from the City for underground lines within city jurisdiction.The utility will also need to obtain Utility Permits from DOT&PF,Southeast Section, for activities within the DOT&PF rights of ways. The Delta Western fuel farm is located on Tract 2D,which is owned by Delta Western.The proposed fuel transfer pipeline from the Delta Western fuel farm to the new power plant will be routed within the dedicated right of way south of 10 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Eneray and Engineering Ocean Cape Road between Tract 2D and Tract A.This right of way is under City jurisdiction;therefore,a pipeline easement will need to be obtained from the City. A permit will also be required from DOT&PF where the pipeline crosses under Airport Road. 5.0 PROPOSED FACILITY IMPROVEMENTS The following proposed facility description is separated into the five following sections: Section 5.1,"Power Plant Replacement",describes the proposed construction of a new power plant; Section 5.2,"Fuel System Upgrade",describes a proposed new power plant fuel system which would be an integral part of the new power plant; Section 5.3,"Heat Recovery System Upgrade”describes proposed upgrades to the existing heat recovery system; Section 5.4,"Power Distribution Upgrade",describes the proposed upgrades to the existing community electric distribution system;and Section 5.5,"Fuel Transfer Pipeline Installation',describes the proposed fuel line from the Delta Western Fuel Farm to the new power plant. 5.1 Power Plant Replacement The new power plant will be a pre-engineered metal building with a slab-on- grade foundation.The operator's room,switchgear room,and bathroom will be located in the west end of the new building.A storage mezzanine will be included on top of this area.Heat recovery equipment and radiators will be located on the south side of the building beneath a covered area.An area site plan and power plant floor plan are provided in Appendix A. The following proposed upgrades will modernize the power plant and improve the overall fuel efficiency,reliability,fire prevention/protection,noise control,andoperationsofthefacility:: e Replace existing generator No.1 with a new CAT 3516B generator. e Reuse existing units 2,3,&4. e Provide critical grade silencers on all generators. e Provide sound-insulated air intake and exhaust fan ducting. e Locate radiators and exhausts on the south side of the building to maximize separation from the school complex. e Provide new radiators and variable speed motor controls. e Provide new 6-port heat exchanger to allow for two separate,redundant generator cooling systems and to optimize recovered heat. e Provide new fire suppression system. e Provide sound insulated control room. 11 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering e Provide engine coolant,fuel,and lube oil piping routed for improved generator and house-keeping access. e Renovate and reuse the existing WOTEC used-oil blender. The proposed new switchgear will be metal-clad switchgear with draw-out vacuum circuit breakers consisting of seven separate 36”Wx96”Dx96"H sections. There will be one section for each of the four generating units.The upper compartment will house the generator controls and relays and the lower compartment will house the vacuum breaker.There will be two separate sections for the four feeders.The feeder breakers can be "stacked”with two feeder breakers in one separate 36”wide section.There will be one separate master section with the generator load control equipment in the upper compartment and the station service feeder in the lower compartment.A front elevation of the proposed switchgear is provided in Appendix A. The new switchgear will provide automatic paralleling and load control of the four generating units.The load control system will monitor the electrical demand on the generators and provide automatic selection of the most efficient generating unit or combination of generating units to meet the demand.The switchgear will automatically start the most suitable engine,bring it up to speed,automatically synchronize the unit,and close the engine circuit breaker.When a unit is taken off line,either for maintenance or due to a reduction in electric load,the switchgear will automatically remove the unit from the bus,reduce the speed to an idle,and allow the engine to cool down before it is shutdown.Additionally, the generator controls and relaying will provide complete protection and monitoring of each engine and generator. The new switchgear will also include a supervisory control and data acquisition system (SCADA).The SCADA system will automatically monitor the generator parameters,such as oil pressure,water temperature,etc.,and electrical load data such as kW,kWh,kVA,power factor,line amps,line volts,etc.This data will be available for export to spread sheets and other presentation tools for submission of required PCE data or local utility usage.; 5.2 Fuel System Upgrade The fuel system upgrade consists of replacing the existing tanks,piping,pumps and associated equipment with a new facility as shown on attached sheet M2 in Appendix A.The tanks will be shop built double wall,horizontal,welded steel tanks built and labeled in accordance with UL 142 and equipped with steel saddles and skids.The system will include one 30,000 gallon bulk tank and one 3,000 gallon day tank.Both tanks will be equipped to comply with EPA requirements for redundant overfill protection for alternative secondary containment systems,and each will be equipped with a fill limiter,clock gauge, gauge hatch,pressure vacuum whistle vent,emergency venting,and level switch. The bulk tank will continue to be filled by fuel truck or by a new buried fuel transfer pipeline from the Delta Western facility.(Refer to Section 5.5 for a description of the proposed fuel transfer system).For truck fill,the bulk tank will 12 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering be top filled and will be equipped with a fill limiter,quick connect,and spill catch basin. The bulk tank will also be equipped with a submersible pump with anti-siphon valve direct piped to the day tank.The day tank fill cycle will be manually controlled by start/stop buttons on the day tank control panel.To provide redundant overfill protection,the day tank will be equipped with a dual point level switch interlocked with the bulk tank submersible pump,and the control panel will be equipped with a timer to limit the pump run time.In the event the day tank is overfilled,the pump will stop and an alarm horn will sound. All piping will be schedule 80 steel except for 1”piping located in exposed areas, which will be schedule 160.All above grade piping will be pre-primed and painted and will be installed on concrete pads,supported from tanks or buildings, and secured with steel pipe straps or hangers.All piping joints will be welded or flanged except for connections to pumps and specialty valves,which may be threaded.Sufficient flanged joints will be provided to allow service of pumps and other devices.All connections to pumps and tanks will be made with stainless steel flexible connectors.Each isolated section of piping will be provided with pressure relieving devices to account for thermal expansion of product caused by temperature fluctuations.Provisions for movement of the piping caused by thermal expansion and contraction will be included.All valves will be steel body industrial grade valves intended for use with fuels. The new power plant,tanks,and piping will be enclosed within a chain link fence with barbed wire top.Three foot wide man gates and 16'wide vehicle gates will be provided for access. Due to the need to provide fuel storage at the new power plant this portion of the project is an essential element of the power plant upgrade and has been included in the power plant cost estimate. 5.3.Heat Recovery System Upgrade Based on the existing generation equipment and 2004 PCE data,the power plant cooling system rejects the equivalent of more than 115,000 gallons of #2 heating fuel per year.Subtracting heat losses for the existing arctic piping,there is about 80,000 gallons of available recoverable heat during the months from September through May.The amount of recovered heat used by the existing school facilities and power plant facilities is unknown,but is estimated to be approximately 30,000 to 40,000 gallons per year.Based on these preliminary numbers,there is sufficient heat available to heat additional facilities.However, there are currently no facilities that are near enough to the power plant to warrant providing recovered heat.There are plans to construct a future public works building in the vicinity of the power plant. As part of the power plant project,the following upgrades are proposed to the existing heat recovery system: e Install new heat recovery loop pumps with variable speed drives. 13 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering e Install new 6-port heat exchanger at new power plant.Combine cooling systems of gensets 1&2 and connect to one-side of 6-port heat exchanger. Combine gensets 3&4 cooling and connect to other side of heat exchanger. e Install a recovered heat energy (BTU)meter at power plant. e Install brazed plate heat exchanger at voc-ed shop to isolate arctic piping loop from shop hydronic piping. e Replace elementary and high school heat exchanger plate packs. e Extend existing arctic piping from old to new power plant. e Provide branch tees for future extension to new buildings. Due to the need to provide heat to the utility buildings and the school complex this portion of the project is an essential element of the power plant upgrade and has been included in the power plant cost estimate. 5.4 Power Distribution Upgrade Due to the condition of the existing distribution system,the existing overhead distribution and underground 5kV distribution system will be replaced with an underground distribution system operating at 7.2/12.47kV for the following reasons: e A single voltage level will standardize transformers and allow redundant backup of one feeder to another. e The higher 7.2/12.47kV voltage allows the feeder conductors to carry more power with less loss than lower distribution voltages. e The higher voltage allows the utility to more efficiently feed loads farther away from the power plant than the lower voltages. e The underground cables operating at this voltage level will provide capacitive VAR support for the Yakutat electrical system.The characteristics of the cable will improve the operating conditions of the system and improve the overall power factor. - A simplified one-line diagram from the generators to the feeders is provided in Appendix A. The distribution system upgrade will be divided into three phases to be constructed depending on funding availability.The phases are as follows: Phase 1:This phase will replace the existing 2400V delta system on Feeder No.2.This includes the area known as "Old Town”and will include all of the services up Mallott Avenue,on Ridge Road,Post Office Road,services in the area out to the Harbor and up to Leonards Landing,and the school complex.This phase will also replace portions of Feeder #1 including the Range Site Subdivision,ASHA Subdivision,Thunderland Subdivision,the new Lakestreet Subdivision,the Delta Western Fuel Dock,and other services in 14 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering the area.This phase will stop at the Range Street South Road and at the Delta Western Fuel Dock. Phase 2:This phase will replace the existing 4160V distribution system out to the Airport on Feeder 1.This includes the overhead distribution system on Airport Road,the Airport,the Glacier Bear Subdivision, and all services on or adjacent to Airport Road.It will also extend out to the USFS services and the RCAG service. Phase 3:This phase will replace the overhead distribution system along Ocean Cape Road and will include the West Subdivision and South Subdivision.It will also include the services not covered in Phase 2 in this area. Note that Feeder No.3 will not be upgraded as it is already 7,200/12,470 volts. This feeder will be incorporated into the project as part of the powerhouse upgrade. Typically,the construction cost of an underground distribution system is more expensive than an overhead system.However,due to the difficulty and expense of upgrading an overhead distribution line while in service,it is more cost effective to construct an entirely new underground distribution system.An underground distribution system can be completely installed and energized prior to taking the existing system out of service.When the new distribution system is complete each existing electric service will be converted to the new system with minimal service interruption. The underground distribution system provides other advantages over the existing overhead distribution system,such as: e An underground distribution system will be more reliable.Underground distribution systems are less prone to outages associated with trees and underbrush disturbing the lines. e An underground distribution system will be safer for consumers.An underground distribution line provides less exposure to the energizedconductorsthananoverheadsystem. e An underground distribution system requires less maintenance and will cost less over the life of the distribution system. Following are major features of the proposed distribution system: e The power plant step-up transformers will provide backup of one feeder to another feeder at peak loading.. e Dead-front pad-mounted sectionalizing equipment will be installed in the distribution system to provide feeder backup.This will allow one or more feeders to provide backup to another feeder.In the event a step-up transformer fails or maintenance is required on a line segment,customer service will be maintained or restored expeditiously.Locations for sectionalizing equipment will be determined during distribution system design. 15 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering e All new transformers and sectionalizers will be provided with stainless steel enclosures.In the marine environment,standard metal enclosures for pad- mounted transformers cannot stand up to the salt laden air.The stainless steel enclosures will provide long term maintenance free service. e The new distribution system will be constructed in accordance with Rural Utility Service standards for underground construction.All equipment will be dead front. e All new primary and secondary cable will be installed in 2”HDPE conduit. This will better protect the conductors from damage and allow easy replacement of the cable in the case of a failure. e All new primary cable will be jacketed,concentric neutral with ethylene propylene (EPR)insulation,and all primary terminations will be through load break elbows. 5.5 Fuel Transfer Pipeline Installation The power plant uses approximately 500,000 gallons of #2 diesel fuel annually. Delta Western truck delivers fuel to the power plant in increments between about 1,000 and 8,000 gallons/delivery,resulting in approximately 3 deliveries per week or 150 deliveries per year. Yakutat Power contacted Delta Western regarding the feasibility and interest of installing a fuel transfer pipeline between the Delta Western tank farm and the power plant. The proposed fuel transfer system includes approximately 1900 feet of below grade 3”schedule 80 welded steel,coated and cathodically protected pipe.The pipeline will tie into the existing Delta Western tank farm manifold upstream of the existing pump that feeds the truck rack loading arm.New isolation valves, centrifugal.pump,fuel meter,and a normally closed actuated ball valve will be installed at the Delta Western facility.At the power plant,the pipeline will top fill the new 30,000 gallon bulk tank and will include isolation valves,a strainer,a filllimiter,and full and overfill level float switches.The bulk tank fuel fill system will be similar to the power plant day tank fill system and will include redundant levels of overfill protection.The proposed pipeline route is shown on sheet M71 in Appendix A. 6.0 PERMITTING AND SPILL RESPONSE The proposed project is subject to regulations of State and Federal agencies including the Alaska Coastal Management Program,the Alaska Department of Environmental Conservation (ADEC),the Division of Fire Prevention,and the U.S.Environmental Protection Agency. 6.1 Environmental Assessment An Environmental Assessment (EA)will be completed prior to construction of the proposed project.An EA is required for all projects that are federally funded or require a federal permit (such as a Corps of Engineers Wetlands Permit).The EA confirms there is no significant impact to the environment caused by the 16 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering project.As part of the EA,a Coastal Zone Management Project Questionnaire will be completed and submitted to the Alaska Coastal Management Program. The Coastal Zone Management Project Questionnaire helps to identify state or federal permits that may be required. 6.2 Fire Code A Plan Review permit from the State Fire Marshal is required for the fuel and power plant portions of the project.Final stamped design drawings will be submitted to the Fire Marshal for review prior to construction.Plans will be reviewed for conformance with the International Fire Code and related codes including the International Building Code and the National Electrical Code.The review process can take anywhere between 3 weeks to 6 months.Plans should be submitted by January to ensure approval in time for April construction. 6.3 Air Quality Permit The ADEC requires diesel-electric power generation facilities to comply with 18AAC50 Air Quality Control requirements.A "General Permit 1A”(GP1A)is required for those facilities which have the potential to emit more than 100 but less than 250 tons/year of nitrates (NOx),but that actually consume less than 827,250 gallons of fuel per year. The existing facility currently consumes approximately 500,000 gallons/year and operates under an existing GP1A permit (105GP1A01).The concept design calls for reusing 3 out of the 4 existing generators at the new plant,and replacing the 4th generator with a new more fuel efficient generator.With the new generator and 3 existing generators,the Utility will continue to operate within the GP1A limits (less than 250 TPY,and less than 827,250 gallons).Bill Walker with ADEC was contacted and confirmed that if the new plant continues to comply with the existing avoidance limits a new minor permit is not required.Mr.Walker also confirmed that a DEC construction permit is not required since the new power plant will replace the existing permitted power plant (stationary source). :-6.4 Spill Response Because Yakutat Power does not receive fuel delivery by marine vessel,the new facility will not be subject to U.S.Coast Guard regulations.However,since the power plant will have oil storage tanks in excess of 1320 gallons,it will continue to be subject to U.S.Environmental Protection Agency regulations which require preparation of a Spill Prevention Control and Countermeasures (SPCC)plan. Since all deliveries will be received by truck or land based fuel transfer pipeline (no direct marine deliveries)the facility will not be subject to U.S.Coast Guard regulation and will not require a Facility Response Plan or an Operation Manual. Spill response gear including sorbent material and protective safety gear will be purchased and left on-site upon project completion along with existing 3,000 gallon day tank to serve as oil-spill contingency storage. 7.0 CONSTRUCTION PLAN The AEA/REG has a history of administering similar projects on a "modified" force-account basis.Force-account construction involves the owner or grantee 17 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering acting as the employer and utilizing primarily local labor.This method tends to achieve a higher percentage of local hire and is strongly supported by many communities and funding agencies.The highly technical nature of power generation and distribution projects requires a limited number of workers with specific experience and expertise to be brought in for the project when not available locally.All work must be supervised and managed by a superintendent with extensive experience in the construction of rural power generation and distribution systems.All specialty work,such as pipe welding and electrical installation must be performed by _skilled craftsmen with appropriate certifications.An experienced construction manager will be required to recruit the necessary skilled labor,coordinate the construction team,and oversee procurement and project logistics.The design engineer will provide quality control through communication with the construction manager and periodic on- site Inspections. The nature of the projects identified will allow most of the projects to be constructed simultaneously and independently from the other.The distribution system upgrades are separate from the power plant and bulk fuel and will not need to be constructed using the same construction management team.The construction of the bulk fuel storage and day tanks will necessarily be a part of the power plant construction.The fuel line to the Delta Western Tank farm can be constructed independent of the power plant. During the construction of the electrical distribution system,the new distribution system must be completely installed and the existing services converted to the new system before the existing system can be taken out of service. There is one basic option for shipping project construction materials and equipment into Yakutat: e Alaska Marine Lines provides containerized freight service to Yakutat. Freight is delivered by ramp barge and offloaded onto the beach in the vicinity of the ferry dock with a large fork lift.The cost associated with this service.is approximately $0.35 per pound from Seattle for containerized freight,including container use.The cost estimate and the project schedule have been developed on this basis.Containers are available in 20,24 and 40-foot lengths. 7.1 Local Job Skills A request was made for information regarding the availability of specialty skilled labor in Yakutat.The requested information has not been received,so the number of skilled laborers available in Yakutat is unknown. It is expected that some skilled tradesmen from outside the community will be needed to support the project including a project superintendent,a certified pipe welder/mechanical foreman,a journeyman electrician,and a journeyman lineman. 18 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Energy and Engineering 7.2.Local Equipment A request was made for information regarding the heavy equipment available in Yakutat.The requested information has not been received.However,the City and YPI have a variety of heavy equipment such as dozers,graders,and trucks. There is also a private construction contractor in Yakutat (Pate Construction)that has a wide variety of equipment including a track hoe,large dozers,dump trucks, and reportedly a 15-ton crane with a 60 foot boom.It is anticipated that almost all heavy equipment required for the project will be available from within Yakutat. Prior to the start of construction,an experienced fleet service mechanic will need to go through the equipment with the local mechanic to ensure the equipment is in proper operating condition. 7.3 Material Sources This project has minor site development so very little fill material will be required. Good quality gravel fill is readily available within the community. 8.0 SCHEDULE For scheduling and funding purposes,the proposed RPSU project has been divided into two sections:Section 8.1,"Power Plant Replacement,Fuel System Upgrade,&Heat Recovery System Upgrade Project Schedule”,and Section 8.2, "Distribution System Upgrade Project Schedule”. 8.1 Power Plant Replacement,Fuel System Upgrade,&Heat Recovery System Upgrade Project Schedule The power plant replacement,fuel storage upgrade,and heat recovery upgrade work will need to be accomplished as one project to maintain uninterrupted utility service.The following schedule has been developed on the assumption that funding will be available in time for construction in 2006.It has been set to take advantage of best seasonal weather for exterior work and building construction. The schedule could be adjusted as required to accommodate funding availability. e Aug-Dec 2005:Design,permitting,and site control. e Dec 2005-Jan 2006:Order building,transformers,switchgear,radiators,etc. e Apr-Jun 2006:Site work and building erection. e Jul-Nov 2006:Mechanical,electrical and new 3516 generator installation. e Dec 2006:Move existing 3508 generator and begin testing. e Jan 2007:Train operators and place community on new generators. e Feb 2007:Move existing 3512 and 3516 generators and commission system. e Mar-Apr 2007:O&M manuals and project close out. Note that initially only one existing generator will be moved to the new plant.This will allow the old plant to remain in service until two generators have been tested and the new plant is ready to be placed in service.Also note that this has been scheduled to take place in the winter when loads are typically low. 19 Yakutat Rural Power System Upgrade Project May 24,2005 Concept Design Report Alaska Eneray and Engineering 8.2.Distribution System Upgrade Project Schedule Work on the Distribution System Upgrade Project has been divided into three separate phases,with construction of each phase dependant on available funding.Construction of each phase can occur independently of one another, however Phase 3 construction must be completed after either Phase 1 or Phase 2 has been completed. It is estimated that work on Phase 1 will take two complete spring/summer construction seasons.It is estimated that construction of Phase 2 and Phase 3 will each take one complete spring/summer construction season. It is recommended that the majority of all trenching work take place in the less rainy months of April through July,and be completed prior to the fall. 9.0 COST ESTIMATE The construction cost estimates have been developed based on a "modified" force-account approach utilizing a combination of local labor,certified craftsmen, and specialty sub-contractors under the direction of an experienced construction manager.Labor rates are based on Title 36 equivalent wages for certified specialty labor and prevailing local force-account wage rates for general labor and equipment operation. Detailed cost estimates are included in Appendix B.Separate estimates have been prepared for the Power Plant Upgrade (including Bulk Fuel and Heat Recovery)each phase of the Distribution System Upgrade,and the Fuel Transfer Pipeline Installation.The estimated total project cost including all design,supervision,inspection,permitting,and a 15%contingency for each component is: e $2,638,033 Power Plant Upgrade e $2,848,047 Distribution System Upgrade Phase 1 e $2,109,236 Distribution System Upgrade Phase 2 ©$728,328 Distribution System Upgrade Phase 3 e $5,685,611 Distribution System Total e $281,973 Fuel Transfer Pipeline Installation e $8,605,617 Grand Total All Improvements The total installed generation capacity of the new power plant is 4,115 kW.The unit cost of the Power Plant Upgrade is $641/kW which is within the Denali Commission benchmark cost range of $1,250 to $500 per installed kW for greater than 1,200kW capacity power plants. 20 APPENDIX A CONCEPT DESIGN DRAWINGS 4 PRESBYTERY SUBDIVISION (1.\OVERALL COMMUNITY SITE_PLAN 15K PADMOUNT SWGR,TYP(3) FUTURELe VACUUM |+ BREAK (SWITCH TYP 'a 1500 kVA ab 2500 kVA Al 2500 kVA | 7.2/12.47 W 4[se we i4.16 kV 7.2/12.47 WV 4.16 kV i T1S5KW wy BBOKW i 600kW 1500kWF 4.16kKV +-_+¥A A 1 200A 0.8 PF 0.8 PI 4.16kV ((2.\COMMUNITY ONE.LINE DIAGRAM 4 |Ssta"4.16KV if/pe | SYSTEMS OUT T AND INCLUDING THE AIRPORT,USFS,AND !

Blvd. Anchorage,AK 99503 RE:CDR Report Dear Mr.Noonan, We have reviewed the CDR report and are in agreement with the preliminary recommendations that were stated in the report prepared by Alaska Energy and Engineering,Inc.We are formally requesting that you continue your work on this project. The only discrepancies that we noticed were the location of the wind monitoring tower locations.The report should state that there are three towers collecting data.#1 is located at the mouth of the ANKAU salt chuck,#2is located at Ocean Cape,and #3 is located at the old Coastguard site. The site that was mentioned (Chicago Harbor),has always been a potential Hydro site. We have looked at it several times but have never had a professional assessment of the project.We have also considered natural gas (methane)development.Several years ago we had a geologist (Mr.Arlen Ehm),do a study on the feasibility for it and found that it would be very expensive to explore this option.With new technology it may be a feasible option again,if I recall he stated that the resource is here,it just needed to be developed. We would also like to explore the option of having a cold storage facility developed for the community utilizing any excess heat recovery technology. We are very open to helping develop any new technology that could benefit all of the small stand alone electrical systems throughout the world,and feel that we have an ideal location for any projects. 1 of2 9/17/2004 We are really excited about being chosen for a major project like this.To help show that we are more than serious about upgrading our system,we would like you to know that we have already purchased two new electronic CAT-B series engines,and are in the process of purchasing another modern engine.If this happens that portion of the project can be eliminated.We also have purchased a waste oil injection system,(WOTEC),which has proven to be very beneficial.We have twenty-four hour operations staffing to keep up on security,maintenance,long term sustainable jobs,experienced people,and keep our load sharing as efficient as possible.We have upgraded our cooling fan voltage to 480,and have installed variable speed drives on the fan motors.New more efficient lighting has been installed at the plant.And we are always striving to clean up our distribution system,and try to lower our line loss. We hope that you can move this project ahead and help us make Yakutat a showcase community for the rest of the state.We will developed a maintenance program that would help sustain the new infrastructure,and have the rates furid a repair and replacement account that can be utilized to keep the system maintained and modern. As you can see we are constantly striving to enhance our Municipal Power System to make it as safe,reliable,and cost effective as possible.Any assistance that you can provide will be greatly appreciated.

Yakutat Power Generation,Power Distribution,and Heat Recovery SystemsUpgrade-Preliminary Recommendations Representatives of the Alaska Energy Authority/Rural Energy Group (AEA/REG)andAlaskaEnergyandEngineering,Inc.(AE&E)have completed site investigation tripsandanalyzedthecollecteddataconcemingpotentialYakutatenergyinfrastructureupgradeprojects.During our site investigations and subsequent follow-upcommunications,several issues were identified that need to be resolved in order to define the project scope so that it can advance to the conceptual design phase.Theseissuesinclude: 1)Status of Existing Power Plant 2)Status of Existing Switchgear 3)Status of Existing Electric Distribution System 4)Estimated Future Community Power Demand 5)Replacement Generator Selection 6)Proposed Power Plant Upgrades 7)Proposed Switchgear Upgrades 8)Proposed Electric Distribution System Upgrades 9)Proposed Heat Recovery System Upgrades 10)Proposed Fuel Storage Upgrades 11)Proposed Installation of a New Fuel Line from the Delta Western Fuel Farm ° 12)Construction Sequence to Avoid Interruption of Services " 13)Other Potential Alternative Energy Projects Re: This letter is provided to summarize and analyze these findings and to present a list ofissuesandpossibleoptionsforthecommunitytoconsider. 1)Status of Existing Power Plant. The actual construction of the existing power plant is not known,but is estimated to befromthemid1960s.It is located on tract A of the South Addition near the southeast comer of the Forest Highway No.10 and the Airport Road.The power plant is housedinacombinationutilitybuildingconsistingoffourseparatestructures:The originalbuildinghousesthegeneratingequipmentandswitchgear;the operators and managersofficeisinanextensiononthesouthsideoftheoriginalbuilding;a covered parking Yakutat Power System Upgrade Preliminary Recommendations area is on the north side of the original building;and a newer building to the easthousesthelinetrucksandonefireengine. The original building is a 60'Lx40'W concrete slab on grade structure constructed of3x6”wood girts and perlins with steel lattice type tapered trusses and exterior metalsiding.The building is not insulated nor is there any interior sheeting.The columns onthenorthsidecoveredparkingareaarerustedatthebasetothepointofnearfailure.The exterior of the original building is in poor condition with numerous holes,and hasbeenbadlydentedfromsnowandsnowremovalvehicleshittingthebuilding.The roofisventilatedwithturbineventsandthewallseparatingthepowerplantandthelinetruckareaisopen.Most of the exposed building material in the original building is plywood. The plant office and manager's office is a 64'Lx24'W metal sided,pre-engineered steelframestructure.The line truck addition is a 64'Lx40'W metal sided,un-insulated pre-engineered steel frame structure.Both are slab-on-grade construction.Whereas theoriginalbuildingisinrelativelypoorcondition,the office and line truck additions appeartobeingoodcondition. The power plant has water problems from both poor surface drainage and a leakingroof.The roof leaks and water has dripped onto the switchgear.During the winter,when the ground is frozen,surface water has flooded into the powerhouse and filled thecabletrenches.There have also been times when the switchgear has had water beneath it. The noise level around the power plant has been of concern due to the close proximityoftheelementaryandhighschoolslocatedtothenorthacrossForrestHighwayNo.10.The existing air intake and exhaust system consists of un-ducted air louvers,whichprovidenosoundattenuation.Also,fan driven radiators for the engines are located inanopen,covered area on the north side of the power plant,which contribute to theoverallnoiseleveltransmittedtotheschoolarea. There have also been complaints of exhaust odors at the elementary and high schools.The prevailing winds for the Yakutat area are from the south and exhaust from thepowerplantisfrequentlyblowntowardtheschools. There are four Caterpillar generators installed in the power plant.Unit no.1 is a model3412withaprimecapacityof330kWat1200RPM.It was installed in the mid-1980'sandcurrentlyhasapproximately42,248 total engine hours.The last major overhaulwasperformedinDecember1997at34,521 hours and it is due for another majoroverhaul.Unit no.2 is a model 3512B with a prime capacity of 880 kW at 1200 RPM.It was purchased new in November 1999 and has 21,041 total engine hours.A top endrebuildwasperformedinMarch2002at9,696 hours.It is scheduled for a majoroverhaulthisfall.Unit no.3 is a model 3508B rated 600 kW at 1200 RPM.It was purchased new in November 1999 and has 3,886 total engine hours.Unit no.4 is amodel3516DTTArated1100kWat1200RPM.It was purchased new in 1993 andhas68,688 total engine hours.The last major overhaul was performed in March 2000at48,525 hours.A top end rebuild was performed in February 2003 at 64,608 hours.The next major overhaul is scheduled for 2006. Unit no.1 (CAT 3412)should be replaced with a larger,more fuel efficient genset tomeettheelectricpowerneedsofthecommunity.With continued proper maintenance and scheduled overhauls,units 2,3,and 4 should each provide 100,000 total operatinghours,barring any unforeseen circumstances,and will be reused in the new powerplant. Page 2 of 9 Yakutat Power System Upgrade Preliminary Recommendations Engine cooling is with four separate radiators.Unit no.1 has a dedicated radiatorlocatedinsidethepowerplantabovetheengineinamezzaninelevelarea.Units no.2and4eachhavededicatedremoteradiatorslocatedontheoutsideofthenorthsideof the power plant.Unit no.3 is equipped with a dedicated skid mounted radiator.Unitsno.2 and 4 provide jacket water heat to the plate heat exchanger located in the fanroom.Recovered heat is used to heat the power plant,utility managers residence,and three school buildings. Power is generated at 4,160 volts,three-phase.There are three separate feeders fromtheswitchgeartothedistributionsystemandonefeederforplantstationservice.Eachofthethreedistributionsystemfeedersisprovidedwithindependentstep-uptransformerbanks.Station service within the plant is 120/208 volt and 277/480 voltthree-phase.Two separate station service transformers provide each voltage level.The original 120/208-volt station service transformer is located on top of the no.4feederswitchgearsection.The newer 480-volt station service power is provided by a75-kVA,oil-filled transformer located in the east addition. 2)Status of Existing Switchgear. The existing switchgear is a 5 kV lineup with Allis-Chalmers oil circuit breakers for threegeneratorsandthefourfeeders,and an FPE air magnetic circuit breaker for unit no.4.The Allis-Chalmers switchgear was reportedly surplus from the original FAA equipmentinstalledattheairportanddatesfromthe1950sor1960's.Unit no.4's air magneticcircuitbreakerwasinstalledin1993andispreviouslyusedequipmentasairmagneticcircuitbreakershavenotbeenmanufacturedsincethemid-1980s.Replacement partsfortheFPEbreakerarelimitedandpartsfortheAllis-Chalmers breakers are no longeravailable;therefore,the existing switchgear should be replaced entirely. 3)Status of Existing Electric Distribution System. The existing distribution is primarily overhead with a small amount of underground.Ingeneral,the overhead distribution system is in poor condition.The original system isestimatedtohavebeeninstalledinthe1960s,although there are no records to verifythedate.The majority of the poles are beyond their useful lives,some of the polesappeartobeindangeroffailing,many of the crossarms are too short,and conductorclearancesinsomeareasdonotmeettheNationalElectricalSafetyCoderequirements. There are three feeders that feed the community and one that provides power forstationservice(feeder 4).Feeder 1 is 2400/4160 volt grounded wye,feeder 2 is 2400-volt delta,and feeder 3 is 7200/12470 volt grounded wye.The three separate feedervoltagesdonotsupportfeederredundancy,as there is currently no provision for onefeedertopoweranother. Feeder no.3 and three subdivisions have underground distribution cable.AllundergroundcableisdirectburiedwithoutHDPEconduit.Feeder no.3 is #2 AWG aluminum,15 kV jacketed concentric neutral direct bury cable.The East and WestAdditionsutilize#2 AWG aluminum,15 kV jacketed concentric neutral direct bury cable.The ASHA subdivision utilizes 5 kV direct buried cables. Each of the distribution feeders is provided with its own step-up transformer.Feeder no.1 has a 1500 kVA pad-mounted step-up transformer and is rated 4.16 kV delta on the plant side with a dual primary switch for connection at either 2.4/4.16 kV or7.2/12.47 kV on the City side.Feeder no.1 feeds the airport,ASHA housing,GlacierBear,YK!I Seafoods,and the West Addition.Feeder no.2 has three,single-phase polemountedstep-up transformers,rated 333 kVA each for a total of 999 kVA,mounted on an elevated platform.Feeder no.2 is rated 2400-volt delta and feeds the main town Page 3 of 9 Preliminary RecommendationsYakutatPowerSystemUpgrade and range area and is in the poorest condition.Feeder no.3 has a 1500 kVA pad-mounted step-up transformer and is rated 4.16 kV delta on the plant side and7.2/12.47kV on the City side.Feeder no.3 feeds the City cannery and Is underground.All three step-up transformer banks are located adjacent to each other near the Forest Road No.10. 4)Estimated Future Community Power Demand. According to PCE data for Yakutat Power,the highest peak demand was approximately1,800 kW and occurred September 2000.The lowest peak demand was 890 kW and occurred March 2003.Unlike most rural Alaska communities,the peak loads in Yakutat occur between July and October,and are primarily associated with fish processing.Over the past several years'fish processing operations have declined and the peakloadshavebeenontheorderof1500kW.Whereas,the "low-peak”load has remainedfairlyconstantatabout1000kW.Daily plant loads vary between about 500 kW and1000kWduringthenon-fishing season (November to June). At present,there are few known near-term or future projects that would increaseelectricalconsumptioninYakutat.The airport is undergoing a renovation includingadditionaltaxiwaylighting.According to Rob Swanson,airport electrical contractor,duetotheinstallationoflowerwattagelightingthereshouldbenochangeinelectricload.AnewsubdivisionisinthedesignstageandtheadditionalpeakloadisestimatedbyYakutatPowertobeabout150kW.For planning purposes,it is estimated that thecommunityloadwillincreaseatarateof2%each year,in addition to the one-time loadincreasesduetothenewsubdivision.Based on this,the generation peak demand isestimatedtoincreaseapproximately350kWoverthenext5yearstoabout1850kW,whereas the minimum load will increase to about 700 kW. Due to the magnitude of the both the daily and annual foad fluctuation,it is important tosizethegenerationequipmenttomaximizefueleconomy,yet provide redundancy sothattwogensetscancarrytheprojectedpeakelectricload. 5)Replacement Generator Selection. It is proposed that the existing unit no.1,CAT 3412,be replaced with a new highercapacityandmorefuelefficientunit.The new generator will need to be prime rated tohelpcarrythefuturepeakcommunityload.A Caterpillar model 3516B with a primeratingof1350kW,at 1200 RPM,appears to be the most appropriate option.Advantages of this generator selection include: Commonality with the existing unit no.4 CAT 3516. 1200 RPM operation for low noise level and long life. e Adequate capacity to meet current peak loads 8 months of the year,and theabilitytoparallelwithanyoneoftheotherthreegensetstocarryloadsbetweenabout1800kWto2300kWasfuturecommunityloadgrowthincreases.

Ability to be operated efficiently with any renewable energy sources that may beinstalledatalaterdate. Page 4 of 9 Yakutat Power System Upgrade Preliminary Recommendations 6)Proposed Power Plant Upgrades. Based on the condition of the existing power plant building and poor area drainage,it isrecommendedthattheexistingpowerplantbeabandonedandanewpowerplantbeconstructedonCitypropertyeastoftheexistingpowerplant.The new power plantwouldbeapre-engineered metal building with a slab-on-grade foundation.Theoperator's room,switchgear room,and storage rooms would be located on the northsideofthenewbuilding.Heat recovery equipment and radiators would be located onthesouthsideofthebuildingbeneathacoveredarea.An area site plan and powerplantfloorplanwillbeprovidedintheconceptdesignreport. The following proposed upgrades are intended to modernize the power plant and toimprovetheoverallfuelefficiency,reliability,fire prevention/protection,noise control,and operations at the facility: Replace existing generator #1 with new Caterpillar Model 3516B generator. Reuse existing units 2,3,&4. Provide new automatic paralleling and load sharing switchgear. Provide critical grade silencers on all generators. Provide sound-insulated air intake and exhaust fan ducting. Provide new radiators and variable speed motor controls. Replace existing plant heat exchanger with new two-pass heat exchanger toallowfortwoseparate,redundant generator cooling systems and to maximize recovered heat. Provide new fire suppression system. Provide sound insulated control room Provide engine coolant,fuel,and lube oil piping routed for improved generatorandhouse-keeping access. Provide a new day tank with level control and overfill alarm. Renovate and reuse the existing WOTECH used-oil blender. 7)Proposed Switchgear Upgrades. The new switchgear would be metal-clad switchgear with draw-out vacuum circuitbreakersconsistingofsevenseparate36”Wx96"Dx96"H sections.There would be onecubicleforeachofthefourgeneratingunits.The upper compartment would house thegeneratorcontrolsandrelayingandthelowercompartmentwouldhousethevacuumbreaker.There would be two separate sections for the four feeders.The feederbreakerscanbe"stacked”with two feeder breakers in one separate 36”wide section.There would be one separate section to house the generator load control equipment. 'The new switchgear would provide automatic paralleling and load control of the fourgeneratingunits.The load control system would monitor the electrical demand on thegeneratorsandprovideautomaticselectionofthemostefficientgeneratingunitorcombinationofgeneratingunitstomeetthedemand.The automatic paralleling systemwouldautomaticallystartthemostsuitableengine,bring it up to the proper speed,andautomaticallysynchronizetheunitandclosetheenginecircuitbreaker.If a unit were tobetakenoffline.for maintenance or a reduction in electrical demand,the automatic paralleling system would automatically remove the unit from the switchgear bus,reducethespeedoftheunittoanidle,and allow the engine to go through a cool down periodbeforeitwasstopped.The generator controls and relaying would provide completeprotectionandmonitoringoftheengineandgenerator. The new switchgear would also be provided with a new supervisory control and dataacquisitionsystem(SCADA).The SCADA system would automatically monitor the Page 5 of 9 Yakutat Power System Upgrade Preliminary Recommendations generator parameters,such as oil pressure,water temperature,etc.,and completeelectricalloaddata,such as kW,kWh,kVA,power factor,line amps,line volts,etc.This data would be available for conversion to spread sheets or other presentation toolsforsubmissionofrequiredPCEdataorlocalutilityusage. 8)Proposed Electric Distribution System Upgrades. Due to the poor condition of the existing overhead distribution system,it isrecommendedthatentireoverheadsystembereplacedwithanundergrounddistributionsystemoperatingat7,200/12,470 volts for the following reasons: A single voltage level will standardize transformers and will allow one feeder tobackupanotherfeeder.; The higher voltage allows the feeders to operate at a higher loading for the sameconductorsize. The higher voltage allows the utility to feed loads farther away from the powerplantthanthelowervoltages. e The underground cables operating at this voltage level will provide capacitiveVARsupportfortheYakutatelectricalsystem.The characteristics of the cablewillimprovetheoperatingconditionsofthesystemandincreasetheoverall power factor. Typically,the construction cost of an underground distribution system is moreexpensivethanforanoverheadsystem.However,due to the difficulty and expense ofupgradinganoverheaddistributionlinewhileinservice,it is more cost effective toconstructanentirelynewundergrounddistributionsystem.An underground distributionsystemcanbecompletelyinstalledandenergizedwithouttakingtheexistingsystemoutofservice.When the new distribution system is complete,each existing electric servicecanbeconvertedindividuallyfromtheoldsystemtothenewsystemwithoutserviceinterruptiontoothercustomers. The underground distribution system also provides other advantages over the existingoverheaddistributionsystem. e An.underground distribution system will be a more reliable system.Undergrounddistributionsystemsarelesspronetooutagesassociatedwithtreesandunderbrushdisturbingthelines. An underground distribution system will be a safer system for consumers.Anundergrounddistributionlineprovideslessexposuretotheenergizedconductorsthananoverheadsystem. An underground distribution system requires less maintenance and will cost lessoverthelifeofthedistributionsystem. The proposed system will maintain the existing three feeders and will reuse the existingstep-up transformer banks from feeder no.1 and feeder no.3.A new 1500 kVA,three-phase,pad-mounted transformer will be provided for feeder no.2. Page 6 of 9 Yakutat Power System Upgrade Preliminary Recommendations Following are major features of the proposed distribution system. e The step-up transformers would provide backup of one feeder to another feeder.At the current peak demand,a 1500 kVA transformer would be capable ofproviding100%backup of one other feeder. e To provide feeder backup,it is proposed that dead-front pad-mountedsectionalizingequipmentbeinstalledinthedistributionsystem.This would allowoneormorefeederstoprovidebackupforanotherfeeder.In the event a step-up transformer failed or maintenance was required on a line segment,customerservicecouldberestoredexpeditiouslyormaintainedduringmaintenance.Locations for sectionalizing equipment would be determined during distribution system design. e All new transformers would be provided with stainless steel enclosures.In the marine environment,standard metal enclosures for pad-mounted transformerscannotstanduptothesaltladenair.The stainless steel enclosures will providelongtermmaintenancefreeservice. e The new distribution system would be constructed in accordance with Rural Utility Service standards for underground construction.All equipment would bedeadfront. e All new primary and secondary cable would be installed in 2”HDPE conduit.This would protect the conductors from damage and allow easy replacement ofthecableinthecaseofafailure. All new primary cable would be jacketed,concentric neutral and would haveethylenepropylene(EPR)insulation at 133%insulation level.All.primaryterminationswouldbethroughloadbreakelbows. The existing 5 kV underground cables in the ASHA subdivision would bereplacedwithnew15kVratedcable. 9)Proposed Heat Recovery System Upgrades. The Yakutat power plant provides recovered heat to three school buildings and powerplantfacilities,and was installed in 1991.The heat recovery system at the power plantconsistsofa6-port plate and frame heat exchanger,arctic pipe loop expansion tank,base-mount circulating pumps,and thermometers and pressure gauges.The 6-portheatexchangercapturesheatfromgensets2&4.Each genset is piped separatelythroughtheheatexchangersothatthecoolingsystemfluidsdonotmix.The recoveredheatistransferredthrough3”arctic pipe to the elementary school,voc-ed building andhighschool(heat is also provided to the utility manager's house).The recovered heatistransferredtotheelementaryandhighschoolheatingsystemviaplateandframeheatexchangerslocatedintherespectiveboilerrooms.The voc-ed shop hydronicpipingisconnecteddirectlytothearcticpipingsystem.The school boilers have notbeenoperationalsincetheheatrecoverysystemwasinstalledandallbuildingheatissuppliedfromtheheatrecoverysystem. The amount of recovered heat available from the new power plant will be estimatedbasedonproposedgenerationequipmentandpresentelectricloadsandcomparedto Anthecapacityoftheexisting6-port heat exchanger and existing school loads.estimate of additional available recovered heat will be determined. Page 7 of 9 Yakutat Power System Upgrade Preliminary Recommendations The following upgrades are proposed to the existing heat recovery system: Install new heat recovery loop pumps with variable speed drives Install new 6-port heat exchanger at new power plant.Combine cooling systems -of gensets 1&2 and connect to one-side of 6-port heat exchanger.Combinegensets3&4 cooling and connect to other side of heat exchanger. Install a recovered heat energy (BTU)meter at power plant Install brazed plate heat exchanger at voc-ed shop Replace elementary and high school heat exchanger plate packs Extend arctic piping to new plant 10)Proposed Fuel Storage Upgrades. The existing power plant fuel storage system consists of a 20,000-gallon self-dikeddoublewallbulktankanda3,000-gallon double wall "day tank”.Yakutat PowerpurchasesfuelfromDeltaWestem,which is trucked to the power plant fuel tanks on anas-needed basis.The existing fuel storage system does not comply with current stateandfederalregulationsforabovegroundfueltanks. Based on historic fuel delivery data and estimated future electric loads,it is proposedthatthepowerplantfuelstoragesystemprovideaminimumof14daysoffuelcapacitybasedonthefollowing: YAKUTAT POWER FUEL CONSUMPTION Current Average Daily Use for Peak Month in Gallons (1)1600 Estimated Future Daily Use in Gallons (2)1975 Current Peak Two Week Use in Gallons (1)22400 Estimated Future Peak Two Week Use in Gallons (2)27650 (1)From Yakutat Power FY03 PCE data. (2)Current peak plus average demand increase of 235 kW @ 15 kW-h sold/Gal. Based on this,a double wall fuel storage tank with a gross capacity of 30,000 gallons isproposedtobeinstalledforbulkstorageplusanew3,000 gallon double wall day tankatthenewpowerplant.Both tanks will be equipped to comply with EPA requirementsforredundantoverfillprotectionforalternativesecondarycontainmentsystems. 11)Proposed Installation of a New Fuel Line from the Delta Western Fuel Farm..° The power plant uses approximately 500,000 gallons of #2 diesel,annually.DeltaWesterndeliversfuelinincrementsbetweenabout1,000 and 8,000 gallons,whichresultsindeliveriesaboutevery3or4days. Delta Western was contacted regarding the feasibility and interest in installing a fuelpipelinebetweentheDeltaWesterntankfarmandthepowerplant.The fuel line wouldbeabelowgradepipelineroughly1600feetinlength.The use of a dedicated pipelineshouldsubstantiallyreducethetimeandeffortittakestoprovidefueltoYakutatPower,as well as improve the reliability of fuel delivery. Based on Delta Western's response,the feasibility of a dedicated pipeline will beaddressedintheconceptdesignreport.

It is imperative to coordinate major infrastructure improvements to minimize outagesandmaximizeconstructionproductivity.A plan will be developed to minimize thenumberofrequiredpoweroutagesandeliminatetheneedtoutilizetemporaryportablepowerunitsduringthepowerplantanddistributionsystemconstruction. The distribution system upgrade can be considered a separate project from the powerplantupgrade..However,depending on the timing between the distribution upgrade andthepowerplantupgrade,some coordination between the two must be considered.Ifthepowerplantisupgradedbeforethedistributionsystem,then the provisions must bemadetoconnectthenewpowerplantsystemtotheexistingstep-up transformers.- A preliminary construction sequence for the power plant upgrade and distributionsystemupgradewillbeprovidedintheconceptdesignreport. 13)Other Potential Alternative Energy Projects Currently a study is being performed under a grant from the Department of Energy toSealaskaCorporationtoanalyzethepotentialforrenewableenergyinSoutheastAlaska,including the Yakutat area.Anemometers are located near Chicago Harbor tomonitorthepotentialforwindenergy.Monitors may be installed in the Ankau SaltwaterEstuarytodeterminetheavailableenergyobtainablefromtidalactivityinaslough.Preliminary results of the potential wind energy will not be available for at least sixmonths.The schedule for monitoring the energy available from tidal activity has notbeenestablished.No other potential alternative energy projects have been identifiedforYakutat.
