Following final checkout of the Trace inverter early in the fourth quarter,the system was tested initially by using it to provide all the power required by the test facility for instrumentation,lighting,and air condition- ing loads as well as to characterize system performance. Following the initial testing period in late September, the system was then connected to the STAR Center grid thus powering the entire facility.The system operated successfully for the last several weeks of FY98.Then it was temporarily placed in storage and replaced with a new inverter slated for installation in a new APS project. Testing of the new inverter should be finished early in FY99 when the original inverter will be returned to ser- vice.Following installation,operational testing of the 30-kW inverter will continue throughout FY99. Metlakatla Monitoring Project A 1-MW/1.4-MWh battery system,designed and built under a partnership of GNB and GE with support from the ESS Program,was installed in Metlakatla, Alaska,in February 1997.The BESS is designed to compensate for severe voltage and frequency excursions caused by the operation of large motors at the local lumber mill in the remote island Indian village.Several years ago,Metlakatla Power and Light (MP&L) installed a fast-response diesel genset to stabilize the system.The diesel operated continuously and aug- mented existing hydrogeneration units that were too slow to respond to the rapid fluctuations caused by the lumber mill machinery.However,operation of the die- sel in this mode incurred fuel and maintenance expendi- tures of more than $400K/year.With input from the ESS Program,MP&L recognized battery energy storage as a potential alternative to the diesel and contracted with the GNB/GE team to supply a turnkey battery sys- tem. The storage system consists of a string of 378 GNB ABSOLYTE IIP series-connected 2-V VRLA cells.The battery has a nominal rating of 756 VDC and is operated at around 80%SOC to enable it to accept energy during voltage spikes.It consists of a PCS,an automatic gener- ation control system,and the batteries,which are housed in a 40-by-70-foot steel battery building on a concrete pad at the 12.47-kV substation for MP&L's diesel gen- erator.The ESS Program funded the installation of a first-of-a-kind remote monitoring capability that dis- plays the battery system status on personal computers equipped with a modem that connects through commer- cial phone lines. 2.INTEGRATION 2-45 Status The ESS Program continues to monitor fuel con- sumption at the Metlakatla system and has collected data from the system for three full years.The diesel fuel consumption at Metlakatla has significantly declined since 1996 when there was no BESS.As shown in Table 2-27,by 1998,when there was a BESS for almost two years,fuel consumption is less than 25 percent of what it was in 1996. Table 2-27.Total Fuel Consumed for the Years 1996,1997,and 1998* Year Fuel (Gal) 1998 75,118(Jan.-Sept.) 1997 143,957 1996 331,534 No data for October,November,or 'December 1998. As Figure 2-24 illustrates,there were several months in 1998,March (209 gals),April (125 gals), May (70 gals),and July (712 gals),when the fuel usage was substantially reduced compared to the same periods in 1996 and 1997.The fuel-usage numbers are so insig- nificant in fact that Excel plots these numbers on the X-axis baseline.The spike in September of 1998 is caused by hydro maintenance and the diesel generator getting more use. The second seminar on Battery Energy Storage for rural Alaska was held in Anchorage,Alaska, November 4 through 5,1997.The seminar was hosted by the Alaska Division of Energy and the invited pre- senters included SNL,GMB,MP&L,and GE.The seminar was attended by 18 managers and operators representing 71 communities out of the 173 villages that receive the Power Cost Equalization subsidy through the Division of Energy.The purpose of the seminar was to highlight the success of the Metlakatla battery system, discuss the key features that contribute to its economic benefits and create an awareness of similar battery stor- age benefits that might be available to other Alaskan communities. In his remarks,Percy Frisby,Director,Division of Energy,emphasized that these Alaskan villages con- sumed 55 million gallons of diesel during 1996 to gen- erate electricity in these villages,and battery energy storage could help reduce this consumption.Following this seminar,the Division of Energy representative indi- cated that he had hopes of funding site-specific feasibil- ity studies that could lead to installation of more battery- storage systems in rural Alaska. Representatives of MP&L gave 'unqualified endorsements of their battery system performance and shared information on the fuel savings to date and other operating benefits of the battery system.

Like most utilities,Prepa experienced rapid demand growth in the 1960s and 1970s,when a burgeoning petrochemical industry promised continued rapid growth. The utility installed more than 2500 MW during the decade,more than doubling its generating capacity.Because construction of a large generating station was less expensive than many small units,Prepa installed four 400-MW,oil-fired units at two of its generating stations.On the heels of the 1979 oil crisis,Puerto Rico's petro- chemical industry collapsed.Load growth stagnated for five years,and Prepa recog- nized that the large units did not support 'the special needs of an island utility and its customers. |Energy production and cost for Case2Costcomponent-Case1 |Generation °.9887 9701 9654'Battery storage --Oo --96 96 Total 9887)8787.9750ra 3.Battery power is inverted to ac line power by two 10-MVA,voltage-sourced,self-commutated, aoe toteemidameaASPANab.tne meee eee THs AvTiCeet”UPS In any utility not connected to a national ian grid,an unscheduled shutdown of a 400- MW generating facility causes electrical overload of generators that remain on-line. Generator speed and electrical frequency can drop from 60.0 Hz to an unacceptable 58.5 Hz in less than three seconds.Even if steam turbines on standby in the utility have enough power for spinning reserve, the units cannot reach full speed during the critical first seconds.Prepa could not rely on its steam plants to prevent system col- lapse.Automatic load shedding was the only way to reduce overload and control frequency during an unscheduled outage. But to shed a minimum of 200 MW was burdensome for the utility,enforced cus- tomer blackouts,and-in the long run- created costs that negated the economy of scale that originally justified construction of large generating plants. Prepa supplies electricity to more than 3.5-million island residents;to manufactur- ers with production of $14-billion/yr,and to hotels,restaurants,and shops that sup- port the island's $2-billion/yr tourist indus- try.Load shedding was an unacceptable solution for the utility and for each of its customer groups, Residents find unexpected loss of power both inconvenient and frustrating.Manu- facturers,however,pay a higher price. Because loss of electric service for even a fraction of a second causes microproces- sor-controlled production lines to shut down,production time,materials,and profit are lost.Tourists,intolerant of power interruptions in the hotels,restaurants,and shops that they patronize,take their vaca- tion dollars elsewhere.Prepa considered a variety of options to reduce the need for load shedding and create better conditions for all of its customers. Engineers analyzed a variety of options to achieve the 300 MW of spinning reserve that the system needed-including load management,upgrading existing generati- ing facilities,enhancing planned generation, interruptible service credits for customers, and installing energy-storage technologies. Preliminary analysis showed that combus- tion turbines,and battery energy-storage were the most cost-effective options.More detailed studies,consisting of three test cases (table)were then made to estimate and compare the present worth of combus- tion turbines and battery storage in 1990 dollars. The first test case considered the costs of two 100-MW gas turbines operating at 60%of capacity to provide spinning reserve and frequency control.The esti- mated total cost of generation with gas turbines in the system between 1990 and 2018 could be $9.887-billion.The second case was a 100-MW battery system,able to support the system until other generat- ing resources could come on line.The total cost of generation over the same 11- yt span could be $9.797-billion,or $90- million less.The third case credited the battery system with the ability to meet peaking needs,with existing peaking units shut down or operating on standby.Gener- ation costs dropped by an additional $47- million.Clearly,battery storage would be more cost-effective than gas turbines for the utility's needs. Prepa decided to install 100 MW of bat- tery storage in 20-MW increments at sev- eral 115-kV substations.In mid 1991,it awarded a contract to C&D Power Sys- EE inemek:ae tion of electrolyte 6.Batteries are equipped with an automatic watering system and 7 compressed-air agitation system to prevent dry-out and stratifica- tems,Plymouth Meeting,Pa,for the bat- teries and to General Electric Co,Salem, Va,for the PCS for the first of the five planned units.Construction of the first facility began at the Sabana Llana substa- tion in August 1992. Designers of the facility used Southern California Edison Co's Chino facility and Bewag's Steglitz (Germany)facility as models for physical and electrical design. Raytheon Engineers,Denver,Colo,pro- vided design services.Completed in Octo-ber 1993,the plant encloses 224,000 ft?of floor space,3200 of which house the sys- tem controls and 192,000 for the batteries.

The PCS has a 95%efficiency,and oper- ates during any system disturbance that causes voltage to drop by 20%or fre- quency to vary by more than 5%of nomi- nal. The control system,supplied by Leeds +Northrup,North Wales,Pa,ini- tiates battery discharge through distrib- uted controllers when the electrical fre- quency drops from 60.0 to 59.2 Hz.

Digital logic circuits switch the system between spinning reserve and frequency control modes and operate auxiliary sys- tems,such as building ventilation and bat- tery-cell watering and agitation.Digital circuits also communicate with controls in the PCS for diagnostics,protection, and gating of the GTOs.Scada allows system operators at a remote location to receive data and alarms and to override automated control functions (Fig 5). A total of 6000 Model XTLWP-51,2-Vbatterycells,supplied by C&D,are con- nected in six parallel 1000-cell strings to provide a nominal 2000 V dc (Fig 6).The flooded lead/acid cells have a flat-plate design with lead/calcium alloys in both the positive and negative plates. Because the duty cycles for spinning reserve and frequency regulation require a few brief,high-current discharges,plus many lower-current cycles at a higher charge rate,the positive plates are wrapped in a fiberglass retaining mat to ensure a battery life of at least 10 years.The rated capacity of the battery bank,when new,is 21.05 MW for 40 minutes,discharging toa cell voltage of 1.67.This capacity trans- lates to 14.1 MWh.The battery racks, holding 72 tiers of batteries,also support an automatic watering system and com- pressed-air agitation system to prevent dry-out and stratification of the electrolyte in the cells (Fig 6). Startup was educational Startup testing highlighted the complexity of integrating an untried battery storage system.In the PCS,eight GTOs failed and black starting caused resonance and high voltage on the 13.2-kV line.Functional specifications for the facility control sys- tem did not perfectly match logic diagrams for circuits.For the batteries,the time tat Sandia Nationa!Laboratories,verified that circulated ambient|E ait would keep the batteries between 85 and 10SF-well withintC&D's specified maximum temperature of 120F.."oe ;DOE's mission to promote development of cost-effective,com- mercially available BESS products for electric utilities by the year F 2000.In support of this goal,the UBS Program is assisting pri- "vate-sector development of fully integrated,modular BESS prod-.F ucts.The first prototype of such a product is at Pacifiic Gas & 6 fons Bete Leas .TARR?VES RITLe oz:ree I ote! >*Quality.20% between delivery and operation made recharge necessary.

Installation of subsequent additional units in the system will be more like instal- lation of a tumkey product.The startup testing of the Sabana Liana facility was completed this month,and Prepa will host the Fifth International Conference on Bat- teries for Utility Energy Storage in July. The Saban Liana installation,as the high- light of the conference,will showcase the potential of battery energy storage as a technical option for utilities for rapid spin- ning reserve and frequency control.= Good offense the best defense against lightning Gor Power Co started an aggres-sive,two-part program three years ago to protect its customers from costly outages caused by severe and frequent lightning strikes.According to Wayne T. Dahlke,senior vice president,power deliv- ery,both cost containment and reduction in outage time have been dramatic. The double-barrel Georgia Power strate- gy uses an up-to-date,ongoing mainte- nance and repair program,and participa- tion in the National Lightning Detection Network (NLDN). Georgia is a hotbed of lighting activity because of several geographic and geolog- ical factors.Observes Robert O.Burnett, power systems analyst at the electric utili- ty,"The proximity to the northeasterly moving moisture off the Gulf,along with the effects of the Atlantic,as well as mountainous terrain producing uplifting atmospheric forces,and westerly moving storm fronts,all combine to produce con- vective storms and associated lightning. Furthermore,wide variations in soil resis- tivity throughout the state-from moun- tains to seashore-contribute to difficul- ties in transmission-line grounding designs.” Grounding grid.When it comes to the maintenance side of the utility's strategy, copper rods and grounds that corrode over time as a result of galvanic action are regu- larly replaced or repaired.In addition,Georgia Power has a program to selective-ly install lightning arresters on transmis-sion lines,and grounding grids at the bot- tom of poles."These arresters,together with timelyregroundingwork,have cut the number oflightning-triggered transmission-line oper-ations by half,”continues Burnett.He addsthat,"our transmission-line improvementprogram,for example,resulted in 800 £1 ceroat WORLD,April 1995 eMBOAAneeltlalelchamAOnaseoBoRenaesatosacnrrt RVICE COMPANYAlyeskapipeline Visitor Pass-Request/Authorizatio Name Social Security No.Company Department Stan Sieczkowski 519-42-7391 Alaska Energy Authority N/A Steve Gilbert 394-78-1036 Chugach Electric Assoc.,N/A Hank Nikkels 134-34-1 427 Anchorage-ML&P N/A John Huppert 574-32-4857 Chugach Electric Assoc.N/A Alex Gajdes 356-46-8276 Golden Valley Electric Assoc.N/A sara Copper Valley Assoc.N/A Ray DeStefano 2 ENG nq Do AL Copper Valley Assoc.N/A N/A N/A Dates(s)of Visit Charge To Location(s)To be Visited From |To Services Yes No B L D Alyeska User Meals 0 |O OC O C]O Power/Vapor -Escorted 11/12/99 11/12/99 Lodging O &oO O O oO O Meals O &O O O CO O tour of VMT -Escorted 11/12/99 11/12/99 Lodging O &®{|O O O O O Meals O X oO O O O oO Lodging oO &O O Ol oO O Fue!mM Xl M mM mM M1 mM Note:Meals/Lodging And Site Visit Must be Coordinated Between Originator and Facility Involved Purpose of Visit and General Comments:(Circle one or more)VIP TOUR,Routine Tour,Work Visit Routine Tour by the Alaska Energy Authority committee members.Alyeska escort will be Dick Stewart @ Power/Vapor,ext.6237.For information,please contact P/V Admin Aide Carrie Carpenter @ ext.6367.

The Power Distribution switchboard has two sections,designated bus A and bus B, connected by a bus tie circuit breaker which will normally be closed.The main generators are directly connected to this switchboard by nonsegregated phase,insulated bus ducts. "A”and "B”main generators and EG-1 diesel generator are connected to the "A”bus. "C”main generator is connected to the "B”bus.A removable link is provided between the A and B bus for connection of a reactor,which would be required to limit the available short-circuit current to the capability of the switchgear if a fourth generator,similar in size to the present three main generators,is ever added to the system. The busses,in normal operation supply the 13.8kV lifeline busses AA and BB,located in the Emergency Response Building and the 13.8kV distribution circuits supplying the Power Plant and Vapor Recovery 4.16kV,480-volt and lower voltage loads.The Lifeline Diesel Generator (LLG)is connected to the Terminal distribution system either through Bus AA or Bus BB.

Snow load monitoring system: Battery situation was discussed.Tom Bassler and Al Peabody had inspected those structures with solar panels and reported the batteries were in good condition.Installing panels on more structures may be a solution to battery level questions.It may also may not be necessary to install panels as large as the ones in service presently.Battery change out will be done late next fall near the end of September. After the loading events over the winter where some data was gathered it was felt by the committee that gaps are present in the reporting system (structures left out of the SNLMS).A permanent fix should be considered at some time as the committee didn't feel confident in the present system. Work Plans MEA had completed their Ground and climbing patrols and Victor distributed a report of items found.Monte reported GVEA would perform it's inspections toward the end of June. Stan had plans to do an inspection of structures 297 and 274 this summer to address possible fixes.Monte contacted Greg Wyman and it was alright for Stan to contact a consultant to consider repairs.

There was a short discussion regarding calibration of the system and Committee felt that it was possible it would take some time before calibrations could be permanently set.The reason is it would take some events to determine settings and as these were weather dependant it may be some time before there is enough data gathered from various events. After some further discussion on actual work procedure and policies,Stan made a motion that the Subcommittee approve the contract proposal and the schedule for training submitted by Dryden & LaRue for maintenance of the SLMS.The contract would be in the amount of $56,000 already budgeted for FY 98 and would terminate on June 30,1998.The motion passed with the following amendments to the schedules: a.MAINTENANCE SCHEDULE Item #4 -Dispatch and Software Maintenance Training;01-18-98 (to be verified by Doug Hall,Dispatch Supt.@ AML&P). Item #5 -Field Technician Training;02-23-98. item #6 -Spring Weather Station Maintenance;04-07-98. IOC approved Operational Procedures;will be attached to the contract. Following approval,it was mentioned that as there is the possibility that more data may need to begatheredduringFY99toproperlysetsystemparameters.Monte requested that in addition to quarterlyreportsthattheMaintenanceSubcommitteereceiveareportintheSpringsoproperplanningcould be implemented if the contract would need to be extended into FY 99.This would allow time for budgeting to be set in place in FY 99 budget.It was agreed a report would be submitted sometime in early May. 1OC Maintenance Subcommittee Conference Call Minutes,December 12,1997 RE:Snow Load Monitoring System Maintenance Contract Page 2 5.Jim Hall expressed the opinion an aircraft could be employed to spot established trails into the ROW as they may move from time to time depending on overflow and other ground conditions.Stan thought the idea had merit and there was no objection from the rest of the Committee. me ee)of ff ».€2CIMUCTIINIE\HUATHIY JHE. 16244 Poppy Dazs Offre 694-1925 tax 699-1426 Coll 244-1995 Inv#1185 January 23,1998 To:MEA &AIDEA Ref:APA line Dougias Sub Station North Reg:Line Clearing Price Per Acre $489.30 Total Acres Cleared 40.56 Between Towers 56 and 69 Total Amount Due This Ritlme §19,846.01 Solewide Clearing Fic.

The main dam warning and danger levels should be revised to retlect the fact that the real maximum seepage is in the range of slightly over 1 cfs when corrected for the bypass flows.The range of influence from precipitation and snowmelt is 0 cfs to about 2.8 cfs.It is suggested appropriate waming and danger level alarm settings would be based upon the actual seepage range maximum of 1.2 cfs plus 1.4 cfs for the average effect of local runoff and 5 cfs for a warning level of 7.6 cfs (use 8 cfs)and a danger level of 13 cfs or S cfs more than the warning level.

Currently,to determine the saddle dike scepage,the EWS logic takes the flows at the confluence sensor and subtracts the flaws at the main dam sensor and the spillway sensor.The concer is that the stage-discharge relationship at the confluence sensor is of large magnitude and approximate due to its location in the very rough sided Solomon Creek Canyon;and the spillway sensor stage-discharge also is not that sensitive such that when the few cis from the main dam sensor and the flows from the spillway sensor are subtracted,the result can be in error by a significant magnitude of flaw.Currently,for all practical purposes,the saddle dike seepage is very low at 1 to 2 gpm during this inspection.What the EWS needs for the saddle dike is the ability to detect a sudden or rapidly increasing trend of seepage from essentially 0 cfs to 5 cfs that would warn the operators of a developing seepage condition that could ultimately devclop into a serous situation that might ultimately result in failure if no immediate corrective repair or other actions are not implemented. It is recommended two possible alternatives be considered ta modify the EWS to be able to predict a sudden increase or rapidly increasing trend in seepage at the saddle dike,The first alternative would be to install a weir and sensor at the toc area of the saddle dike and connect it to the EWS.The second alternative would be to install a weir and sensor in the vicinity of a previously installed sensor in the spillway creek channel below the penstocks crossings and connect it to the EWS.It must be recognized that flows measured in this location will be areatly influenced by local mnoff from the approximate 0.13 square mile drainage area contributory 1o the sensor location.It will be necessary to develop correction factors to the measured flows at this second alternative sensor location to reflect the effects of precipitation and snowmelt on the intervening small drainage arca.As such,a manually read weir at the toe of the saddle dike would assist in developing correction factors along with precipitation station values.It may take a few years to develop reliable correctian factors that can be factored into the EWS logic.Until such reliable correction factors can be developed,the warning and danger alarm settings should not be entered into the systern to avoid erroneous alarm signals.There is a possibility that with this second alternative,correction factors may not be attainable to a level that the EWS will be able to reliably detect a sudden increase or rapidly increasing trend of seepage from essentially O cfs to 5 cfs that would warn the operators of a developing seepage condition,At times when the spillway operates,this sensor will essentially be out of service due to the magnitude of the spillway flows.

To address this concern,I have redrafted certain portions of the report text on pages 16,19,20, and 3 that discuss the situation.Attached is the proposed substitute language for these pages. The change on page 16 more fully discusses the situation,provides two alternatives for consideration,but leaves the decision to AEA to select which they will pursue taking into consideration the unknown risk of success at the proposed downstream sensor location near the penstocks. Perhaps the saddle dike location wires could be run underground in arcas where there are soils and in conduit bolted to rock in other areas if there is a concern about vandalism or bears eating the wires if above ground. Let's discuss this as soon as possible so that [can proceed with the final report.

Westinghouse Breaker Change-outs Schedule is as follows: GVEA's schedule is for three days beginning February 12,1996. Healy B17 will be by-passed to the transfer buss.All relaying will allow faults to clear at the GHS breaker. Paul Rissee said as he understood it there was a window in March for an outage on the tie and his plan was to use the week of March 11**through March 15%.He thought it would take the full week,but if necessary once the new breaker was in place they could re-configure the relays at Teeland and allow the tie to be put back into service.The subcommittee felt that with all the time and work involved in re- configuring the relays and changing them back after the breaker was ready it was just as well to take the full five days for change-out and be finished with the change. Tom Jaekel stated MEA would like to use the week of March 4% through March 8*and would like to have a service engineer from AEG assist with the installation.The deal with AEG on the purchase was for an engineer to be there at one of the change-outs so this was felt to be the proper time to schedule this.MEA will contact Doug OD'Ewart,the sales representative for AEG,and make the arrangements for the service engineer. It was suggested that the service engineer of AEG provide the suggested "Maintenance Check Schedule”which is to be integrated into the IOC Maintenance and Procedures Manual. O I0C Maintenance Subcommittee Meeting Minutes -February 7,1996 Page 2 (*) II. Paul and Monte suggested that at a minimum each utility should stock spare parts consisting of a trip coil,closing coil,and a cranking motor.One of each was furnished by AEG and are in inventory at GVEA.These items are very inexpensive and if needed rapidly are fairly simple to change-out. Discussion ensued about the old breakers and no one is interested in maintaining them in inventory.Stan Sieczkowski said each utility should send AEA a letter advising the State "These breakers were removed from service because of a safety defect.Further direction from the State as to disposal is requested”.At present no one has any use for them.Doug suggested as a minimum the bushings should be removed and destroyed before the State makes any attempt to surplus them. Note:MEA's outage for breaker change-out moved to the week of February 20°through March 1%. Tower Maintenance Schedules and Patrols Monte reported that GVEA plans to perform its annual ground and climbing patrol during the period of June 10°through June 21°*.During these patrols there will be an outage requested on the tie for two days to re-clip the statics on structure #702 and #739. There was some discussion regarding this area.Monte reported that at present he has no firm grasp on what is happening to the towers,but suspects from records made of the annual triangulation done on structure #749 that the hillside in Windy Canyon appears to have some movement.The area involved appears to be from (approximately)structure #690 through structure #750,just south of Healy.This may have some significant impact on the line in the future,but at present there is not enough data to make firm determinations on the extent of the problem. GVEA also plans to re-adjust the guys on several structures that have had jacking of anchor piles.This will take place during late April or early May.No anticipated outage is being considered. In late Fail GVEA will recheck the levels and triangulation on structure #692 and #749. IOC Maintenance Subcommittee Meeting Minutes -February 7,1996 Page 3 IIl. Iv. ROW Reclearing Plans Tom Jaekel of MEA brought in pictures of the reclearing completed last season.The area under the bottom of the wire was cleared with an access trail between structures. The committee felt that we should go to a full ten year reclearing cycle on both north and south ends.The cost should be budgeted as such through the I0C Budget Subcommittee.The reclearing should be for the full width and length of the ROW cleared during intertie construction. Marker Ball Replacement Some discussion was undertaken in regards to marker ball replacement.Monte reported he had received a query from Air Logistics in regard to using a setup that installs marker balls with a helicopter.The costs involved would probably be fairly high for just one or two installations.However,the intertie and other transmission lines in the State where installations are necessary may make it more cost effective to use this method.Stan mentioned that AEA has several locations that need installations. Tom stated he would contact Soloy Helicopter to obtain costs and Monte said he would contact Air Logistics. The next meeting is scheduled for: Date:September 25,1996 Time:10:00 a.m. Location:GVEA This will give participants time to compile the results of the 1996 ground and climbing patrols.

I.Structure Repairs Tower problems were discussed with no change in recommendations from the Maintenance Subcommittee. Monte circulated his report on final repair costs of structure #758 where the piling failed.Due to access problems and location,cost was in the $230,000 range,It should be noted that repair of structure #598 should be significantly lower,as access is good (%mile from highway down section line).However,beaver ponds are present. Freeze-up is a must before access is possible, Discussion on temporary fixes and re-guying followed with strong feelings that the recommendations on guying made to the Ioc in the meeting include both permanent and temporary{i guying (i.have some method of strain relief and that both northern and southern maintainers comply with any engineering recommendations regarding same). Dough Hall suggested that since there are other lines of similar designs in use in the state,any data on repairs and maintenance recommendations from other maintainers be shared with IOC members.Also,any data and methods IOC maintainers may have can be passed along to others.The subcommittee members felt this sharing of methods would only help to increase reliability and time frames for repairs.

Breakar Discussion Discussed problems with Westinghouse breakers,as both Teeland and Douglas breakers have not had safety checks performed.It was recommended that these he done as soon as possible. Monte distributed an estimate and comparison of costs to have bushing flange problems repaired vs.replacement with new breaker.Considering the Budget Subcommittee was meeting the samé day and discussing the same issue,this subcommittee felt no need to make a recommendation at this time. Right-of-Way Reclearing Reclearing was discussed in light of the completion of MEA's reclearing contract.Doug said he would like to see pictures of the reclearing.Monte said he would like to see reclearing done on a 10 year cycle.Discussion followed and the committee recommends this procedure be implemented by IOC. Doug!Hall said the whole Right-of-Way should be recleared forthefullwidthandlengthofspan.The subcommittee agreed and felt this would definitely allow us to keep the Right-of- Way in proper condition.This is not just from an outage stand-point,but to allow better access for maintenance also. MEA 115 KV Lina Had short discussion regarding MEA's 115 Kv line.Tom reported Jim Hall was discussing options on payment with the Budget Subcommittee.

FAILURE TO FOLLOW THIS SAFETY ADVISORY COULD RESULT IN DEATH, SERIOUS PERSONAL INJURY,AND/OR PROPERTY DAMAGE It is the purpose of the this advisory to alert users of Westinghouse-type DWE Power Circuit Ore tows rated 121,145,and 169K of the need to make an immediate visual inspection ofthelowerbushingflangesoftheinterruptersideof121and145KVbreakersandbothlower flanges of breakers rated 145KV,SOKA and 1L69KV. It has been discovered in some field installations,that the cast aluminum alloy flanges at the bottom of the larger and tapered porcelain weather casing which houses the interrupter on121and145KVbreakersorthesameweathercasingonbothsidesof145KV,SOKA and-169KV 'breakers may not meet metallurgical specifications and are therefore subject tocrackingatthethinwallsectionadjacenttooneoftheflangemountingbolts.If cracking occurs,the strength of the mechanical attachment of the flange to the weather casing is reduced and it is possible for the pressurized porceiain to eject out of the flange.This has happened in three cases.Ten other flanges are known to have cracked.Fortunately there have been no personnel injuries,although it is clearly recognized that the potential exisrs for damage to substation equipment and injuryto personnel or even death. It is recommended that the 121,145,and 169K V-type DWE breakers be considered as potentially dangerous to personnel and property until the recommended corrective actions are completed. An immediate visual inspection of lower flanges on the specified breakers is recommended to search for cracks. © In order to make the visual inspection,the breaker must first be de-energized electrically andgroundedfollowinglocalsafetyprocedures.The SF,gas pressure must be reduced to 5 psigwhilepersonnelmakethevisualinspectionforcracksinthelowerflangestoprecludea bushing ejection from occurring during inspection. After de-energizing and grounding the breaker and reducing the SF,pressure to 5 psig,acarefulvisualinspectionshouldbemadeforlongitudinalcracksinthethinwallsectionsof the flange which are recessed for the flange mounting bolts.Refer to Figure 1.All thin wall sections adjacent to the flange mounting bolts are to be inspected.If any cracks are observed,the breaker should remain off-line with SF,pressure at 5 psig until corrective action is completed. If no cracks are found in the specified lower flanges,the breaker may have the ground removed,be re-pressurized,and energized electrically,but still considering it as potentially dangerous until the following three corrective actions are taken. These three corrective actions are recommended to be taken as soon as the specified breakers can reasonably be scheduled for outage. Corrections are: (1)Because of a recognized quality problem in the metallurgy of the lower flanges of the interrupter side tapered bushings of 121 and 145KV and the tapered bushings on both sides of 145KV,SOKA,and 169KV breakers those bushing assemblies should all be replaced in order to eliminate the possibility of funire flange cracking and subsequent porcelain ejection with the obvious risk to personnel and property. The porcelain/flange assemblies should be returned to ABB in order to have the marginal flanges removed and replaced wiih quality flanges,reusing the existing porcelains.ABB Power T&D Company presently supports all named breakers with replacement parts,service,and technical assistance as Westinghouse no longer mavv:factures high voltage circuit breakers. Inspection at the factory once the flange is removed may reveal that some porcelains shipped prior to 5/31/83 might also need to be replaced.Some pre- 5/31/83 porcelains have been found to not have the sand band fully applied. (The abrasive gripping surface on the lower end of the porcelain that is enclosed by the flange.)There have been several instances reported where a slow SF, gas leak has been determined to be caused by the short sand band allowing minor movement of the porcelain which defeats the gas seal. O Page 3 (2) (3) we April 19,1995 Loose hardware has been found in several DWE breakers,one of which failed catastrophically due to the loose hardware.The loose hardware was found at the top and bottom of the internal epoxy insulating pedestal which supports the interrupter.Refer to Figure 1. The loosening of the hardware is more likely in breakers with higher numbers of operations,but there is long term potential for loosening in all DWE breakers and .nerefore the problem must be corrected to prevent jamming of the contacts and possible failure to close with attendant hazard to personnel and property. Loosened hardware was also found in a breaker that would not be considered as having a high number of operations. Corrective action involves removing the hardware,applying Loctite#271 (red), reassembling hardware with applied Loctite,and torquing to 40 ft-lb.The Loctite may be purchased from local supply houses, Excessive wear has been observed in several 145DWEAO breakers in regard toa linkage connecting pin in the lever box.Refer to Figure 1.The wear is more apparent on breakers with a high number of operations,but is also a potential long-term problem for all of the following type DWE breakers,and excessive wear was also noted on some breakers with a moderate number of operations. 121DWEz0 145DWE20 121DWE31 145DWE40 121DWE40 Consequences of excessive pin wear are the potential for jamming or the contacts being left in an intermediate position,both conditions possibly resulting in breaker failure with hazard to personnel and property. For breakers subjected to frequent operation,the following corrective action is recommended: e Replace shaft seal lever located inside lever box with heavy-duty lever having approximately 75%contact surface between lever and pin. «Install new more durable pin connecting vertical operating rod to shaft seal lever. Corrective action recommended for breakers operating on an infrequent basis consists of replacing the pin connecting the vertical operating rod to the shaft seal lever with a new more durable pin. There is no recommended corrective action for lever box components on the following type DWE breakers: 121DWES50 169DWE31.5 L69DWE20 169DWE40 Heavy duty shaft seal levers and more durable pins were used on these breakers when they were originally manufactured. In summary,an IMMEDIATE visual|inspection for cracks in lower flanges of taperedbushingsontheinterruptersideof12)/and 145KV DWE breakers and the tapered bushings on both sides of 145KV,SOKA,and 169KV breakers is urgently recommended. Breakers determined to have cracked flanges should be kept off-line with reduced SF,gas pressure of 5 psig. ALL DWE BREAKERS SHOULD BE CONSIDERED AS POTENTIALLY DANGEROUS UNTIL THREE CORRECTIVE ACTIONS HAVE BEEN TAKEN (1)Replacement of all lower flanges on the tapered bushings to prevent future cracking and the potential porcelain ejection. (2)Application of Loctite#271 on hardware at the top and bottom of the internal epoxy insulating interrupter support in order to prevent future hardware loosening. (3)Replace shaft seal levers and pins connecting vertical operating rods to shaft seal levers to prevent possible jamming or malfunction in the following DWE breakers: ¢"{21DWE20..145DWE20 TSIDWE31 145DWE40 121DWE40 For assistance in developing a corrective action plan,please contact the ABB Electric Utility Sales Office serving your area,or the local ABB Distributor. A follow-up advisory will be issued by ABB to inform of the availability of the replacement bushing assemblies to permit initiating a rotation program for replacement and also the availability of shaft seal levers and durable linkage pins.The materials will be available for purchase from ABB Power Circuit Breaker Parts and Service. April 19,1995 Page 5 During the interval when the breakers are in service waiting for the three corrective actions to be completed,a significant change in the SF,leak rate should be recognized as an indication that a bushing flange problem has developed and the visual inspection of flanges as outlined at the beginning of this letter should be undertaken. AS STATED PREVIOUSLY,ALL DWE BREAKERS SHOULD BE CONSIDERED AS POTENTIALLY DANGEROUS UNTIL THE THREE CORRECTIVE ACTIONS ARE COMPLETED. Users of SF;DWE breakers should contact your ABB Electric Utiliry Sales personnel or your local ABB distributor to: 1.Obtain written instructions to assist you with making the corrections. 2.Obtain RMR instructions for the remrn of bushings and/or breakers to ABB for refurbishment. 3.Obtain pricing and scheduling information for the parts and services to implement the above corrections."

At present,the tower is stable and in no danger of falling.Our plans are to monitor the movement by having Stutzman Engineering set some vertical control and shoot levels on all four comers of the foundation.This they can do at minimal cost as they will be reshooting tower #749 at the same time. Greg will look at the original foundation and construction information to determine what conditions may have been encountered during construction.This plan should give us an idea of what is happening and we can then determine the most effective method to stabilize the structure. cc:John Cooley,IOC Chairman a,T1M »-_- =) Oren VALLEY ELECTRIC ASSOCIATION INC.Box 71249,Fairbanks,Alaska 99707-1249,Phone 907-452-1151ipyeBNPDe® Alaska InciusNovember20,1995 @$K2 Inch EntP|ie mare TO:IOC Budget Subcommittee Members FROM:Northern Maintenance Contractor -GVEA RE:FY 95 Maintenance Expenses At the last subcommittee meeting the large maintenance overruns were questioned.I promised at that time to summarize the expenses the Northern Maintenance Contractor had incurred.oO.1.Three towers had maintenance or ongoing maintenance performedonthemduringFy95.Tower #598,#750,and #758 were repaired,monitored,or engineered for repair.

II Selection of Permanent Storage Location for SubcommitteeRecords/Reports °The State of Alaska is in the process of microfilming the original construction files except for the Mylar drawings.These will be available to subcommittee members if requested. °Hard copies that would normally be destroyed are to go the appropriate utility responsible for maintaining that portion of the line. °Summaries of patrols and inspections are to be submitted to the subcommittee.A report and summary will he presented to the IOC (these reports will mainly consist of problems and unusual findings).The IOC contract specifies reports are to go to the State of Alaska as owner of the line. °Files and subcommittee correspondence is to be retained by the appropriate parties.Full documentation to he maintained by GVEA. °At present,a list of spare parts is disseminated to the State and MEA for their records.GVEA has inventory. Intertie Maintenance Subcommittee Meeting Minutes of April 4,1995 Page 2 III IV Schedule of Planned Breaker Maintenance ABB is presently scheduled for the period of June 12-29. Chugach will try to arrange for use of gas cart prior to scheduled maintenance. Breakers to be checked include Healy,Douglas and Teeland. The Chairman will forward to the committee members,an outline of recommendations from ABB for the checks. While the line is scheduled for maintenance,Chugach will check Teeland transformer,and Doble for baseline. ROW Reclearing Required Subcommittee recommends the IOC approve a ROW reclearing budget amount on an annual basis. Southern end of tie needs to have original clearing limits reclaimed.MEA will submit an estimated cost for clearing that section of line.The size of the section should be large enough that bids will be representative of probable costs.If too small,then bid prices will reflect too large a mobilization cost. Northern end of tie mainly needs clearing for helicopter access and for areas around tower sites.GVEA will submit an estimated cost for clearing these areas. Tower Problems Snow loading problems were discussed.Stan Sieczkowski mentioned that a.procedure was adopted by the I0C.for mitigating problems as they occur (see attached). Summarized the following tower foundation problems.Will follow-up with attached plans as necessary to make final recommendations on corrective actions. A.Tower #598 -Soil tests complete.Final fix will be ready for next winter. B.Tower #510 ț -Both towers are leaning.The plan is to look at the measurement records and check them against the construction records.Presently they measure about 8-10"out,and haven't moved in three or four years. Intertie Maintenance Subcommittee Meeting Minutes of April 4,1995 Page 3 VI VII VIII Cc.Tower #692 -Self-supporting tower is presently leaningabout12-18"downhill.Will investigate when the snow is off the ground and get some elevations.Suspect the problem is similar to tower #749. D.Tower #701 ˣ -Static appears to be pulled out of sag.Will investigate at the same time as tower #692. There are some airplane markers missing.Will investigate the use of a type that can be placed by helicopter slink line. The can be done when performing patrols and save the expense of special helicopter use. Intertie Access Problems Most accesses on the intertie were established for only a three year period to complete construction.Recommend the IOC obtain permanent easements or ROW's for access. MEA and GVEA will provide Stan Sieczkowski (State)with a map showing locations of access points presently used.He will present the map to the IOC for general discussion. Determine Date and Agenda for Next Meeting Unless requested otherwise by the IOC,the next meeting of the Intertie Maintenance Subcommittee will be held on August 15, 1995 at MEA.Chairman,Monte Ervin,will confirm plans and agenda just priorto that time. Adjournment Meeting adjourned at 4:15 PM. wewtonRevised 3-15-95 Differential Ice Loading The following is a written procedure which is consistent with pastpracticeswhendifferentialiceloadingisencounteredontheAnchoragetoHealyIntertie.This procedure should be formally adopted by the Intertie Operating Committee. A.The Matanuska Electric Dispatcher will notify the northern and southern controllers of a snow load warning as soon as snow loading is suspected to be occurring in the Willow-Talkeetna area.The snow load warning will normally be triggered by reports of heavy snowstorms,or snow related distribution line trips in these areas. If a report of low wires or reduced clearances is received on the transmission line,the Matanuska Electric Dispatcher will notify the northern and southern controllers,and the line will be de-energized.Matanuska Electric will dispatch personnel to the location as soon as reasonably possible to assess the situation,and clear the line or otherwise correct the problem. If the clearance problem cannot be corrected immediately,then Matanuska will notify the northern and southern controllers, and recommend a course of action necessary to solve the loading problem. If the Matanuska Electric Dispatcher believes,or is informed, that conditions exist which could cause reduced clearances from differential ice loading,then the Dispatcher will discuss the need for an aerial patrol with the northern and southern controllers.Matanuska Electric will perform an aerial patrol of the line as soon as reasonably possible. Proposed Additions: Insert at the end of paragraph A above: A patrol of the line will be conducted at the first available time following any snow load warning.The patrol will assess the amount of snow on the wires and the potential for these loadings to create differential ice loading conditions. If the snow loading is determined to cause potential for reduced clearances from differential loading at a future time, Matanuska Electric will have the northern and southern controllers remove the line from service,and remove the snow loading from the line.After the snow load has been removed, Differential Ice Loading Revised 3-15-95 Page 2 Matanuska Electric will notify the northern and southern controllers to have the line placed back in service. For emergency purposes only;the Intertie may be left in service even if differential loading might occur. Insert as new paragraph "E": The Maintenance Contractor will provide a written report of conditions found,action taken to resolve problem,labor and equipment used,and if appropriate,provide recommendations. The report,including any photographs,will be sent to the Alaska Energy Authority with copies to the Northern and Southern Controller and the IOC Chairman within 15 working days of the incident.

FROM:Brent Petrie ut SUBJECT:Snow resistant transmission line conductors I recently attended the Winter Cities exhibition held in Anchorage and saw several exhibits dealing with electric and water utilities.Being aware of some of the problems that are occurring on the Tyee project T-line,I picked up some information on snow resistant conductors designed by Hokkaido Electric Power that are enclosed for your information. Perhaps their system would relieve some of the weight on the Tyee structures. Hokkaido Electric Power Co.,Inc.is respon- sible for electricity supply in Hokkaido and has some 11,920 circuit km,overhead and un- derground transmission lines. The winter climate in Hokkaido is very severe.Hokkaido,which is the northernmost island,is sometimes struck by violent snow- storms which bring about large scale snow accretion and transmission lines.This snow accretion has caused some towers to collapse or conductors to break in the past.To cope with these,we have developed a snow- resistant ring and an anti-torsional damper. Process of snow accretion a The snow accretion occurs in early winter or early spring more than midwinter.Generally,the snow accretion has a high specific gravity of 0.6 -0.8, and occurs when wind velocity is 10 m/s or over and the temperature is between 0 to 2 °C (snow is wet). The snow accretion grows towards the windward side first,and then rotates around conductor.In the case of a long-span,the eccentric weieht of snow accretion will cause a conductor to twist.This process is shown in Figure 1. snow ee >&>>slide Ene "4 By)v Figure 1.Process of snow accretion Snow resistant ring The snow slides along the strands and grows cylindrically.To cope with this,we fit rings on the conductor at some intervals.The result is that the rings prevent the settled snow from sliding in the direction of strands.The snow accretion grows in the horizontal direction and falls off the conductor as the eccentric weight of accretion grows.This principal is shown in Figure 2. Ring Y Falling rotating snowFigure2.Conductor with snow-resistant rings Anti-torsional damper When the span length is short,this "ring method”is remarkably effective in preventing snow accretion.In case of long-span length,however,this method has little effect because the torsional stiffness of the conductor is low at the mid-span.This phenomenon is illustrated in Figure 3. a |--Let us suppose that a certain volume of snow settles on the conductor and the span||=|is divided into a few sections.As shown in the first stage,when a little snow|accretion occurs on the windward side,various parts of the divided section are »y-a a y-twisted.as Testage In the second stage,the parts of the section are further twisted.If this process A A A A is followed by a third or fourth stage,the snow accretion becomes cylindrical in °"2nd stage ....::the mid-span,but it only lies on the conductor near the insulator strings.This means that the snow near the insulator strings falls off,but does not fall from the-3rd stagewsa2®osmid-span. :Therefore,to increase the snow-resistant effect of a long-span,the torsional-B -S 'of Toe -4th stage stiffness must be increased.i 3 Anti-torsional dampers are therefore installed along with snow-resistant ringsFigure3.on conductors. Process of snow accretion in a long span Snow resistant-conductor Conductors with snow-resistant rings,or snow-resistant rings and anti-tor- sional dampers are referred to as snow-resistant conductors. The ratio of snow-resistant conductors is above 95%in our company. After installing snow-resistant rings and dampers there have been no tower collapses.This technology is also applied in other regions of Japan as coun- termeasures for snow accretion and similarly good results have been obtained.

ROM:Joe Schneider,Supervisor of Planning,Maint.&Sched. SUBJECT:Unit Ratings for MRSC. As you are aware,we need to review and analyzed unit performance of all the power plants. In order to check and validate the results of the prior unit performance tests,I propose that we discuss using SCADA data. Only Beluga units 3,5,6,7 &8 have enough SCADA data to provide valid information due to there large number of fired hours at temperature control.The other units in the system still require regular performance tests. Check Ellis and I have discussed the methodology and propose that the SCADA information be sorted by mW output as a function of 1 deg F temperature increments.Only mW values that were 'blocked' (SCADA's version of temperature control)would be accepted.MW output will be provided as a mean of all the values found at that temperature,the number of values used to calculate that mean will be provided.Also provided will be the maximum and minimum mW values and a standard deviation.

Mr.Gerdes is still in the process of gathering this information and plans to have it available at the next meeting. c.Frank Abegg of GVEA will locate information on mining loads for review by the committee. GVEA Engineering is in the process of a study to determine the impacts of mining loads. Mr.Abegg will be able to share that information when the study is completed. d.Weldow George of Anchorage ML&P will locate information on the SMES for review by the committee. Mr.Moe Aslam of Anchorage ML&P attended this meeting to provide information on the Superconducting Magnetic Energy Storage (SMES)system being planned for installation at Anchorage ML&P.Mr.Aslam provided copies of a paper he co-authored on the subject which was presented at the 1994 American Power Conference. ML&P is working on a study of the need for turbine governor /AGC coordination with SMES and battery systems on a limited basis.The MRSC discussed the possible need for a more formal study to develop recommended calibration and operational guidelines. e.All members will advise the chairman of the location of Digital System Monitors,(DSMs')installed in their systems in order to develop a list for distribution to MRSC members. The following list of DSM locations has been assembled by the MRSC. AEA.........Bradley Lake Power Plant GVEA.......GoldHill Substation Chugach.....Bernice Lake and Beluga Power Plants ML&P.......Plant II with one to be added at Plant I some time in the future. As a follow up to this list the MRSC members will develop a list of the points being monitored by the DSM units installed.The MRSC will also develop a draft specification for the use of DSM to be considered by the IOC as a guideline.It is hoped that this will help to establish common criteria for railbelt system analysis.The MRSC also considered the benefit of coordinating the time base of all railbelt DSM's to a common clock such as to a satellite clock. f.There will be an update of the handbook for this year.The Bradley Lake performance graphs will be improved.If there are other changes to unit or plant data that members wish to have included please bring them to the attention of the chairman. g.Hank Nikkels of ML&P distributed information on turbine governor droop under varying ambient conditions.Discussion on this subject will take place at the next MRSC meeting. h.Moe Aslam also distributed a paper that he authored on the Eklutna Hydro Rewind/ Upgrade which was presented at the IEEE Anchorage meeting August 16,1995. i.Frank Abegg of GVEA distributed an information packet on the Healy Clean Coal Project. 6.Assignments for next MRSC meeting Dave Gerdes of FMUS will provide the chairman with an updated performance graph to more accurately indicate steam plant electrical generating capability when steam is being extracted for heating.

This maintenance program is of a routine or preventive nature for the purpose of maximizing the utilization of the Intertie for the benefit of the interconnected utilities and for protecting the investment in the Intertie facilities.The program does not present methods or procedures for the repair of major damage that may occur,from time to time,as the result of third parties,the elements,or other causes.However, recommendations are made for stocking spare parts,materials,tools ) and equipment for making such repairs.It is recognized that during the next several years the Intertie will be operated at 138 kV,although designed to operate at 345kV.Although it will have an increased significance in the operation of the interconnected systems at the higher voltage,the programs,schedules,tools and equipment will not change as a result of the system voltage increase. Any inspections,operations or maintenance of facilities shall be carried out utilizing the work rules given in the current NESC,Part 4,REA Bulletin 165-1 and the APA Safety Manual.Personnel using this 62/1APA MP/D7 1.2 1.2.1 maintenance program shall be qualified by experience and training to work on substation equipment or transmission lines as appropriate. Inspections,operation and maintenance shall be in accordance with manufacturer's instructions where they are available and applicable. It is important that all maintenance inspections and work is thoroughly performed in a quality manner and all findings and actions are well documented. A review of the previous Maintenance Inspection records,as well as outage reports of the line and any other pertinent records or reports, will alert the inspector of specific types of problems to be aware of. The Intertie maintenance tasks identified in this program are those that are included and defined in the Uniform System of Accounts as follows: a.Account Number 562 Station Expenses b.Account Number 563 Overhead Line Expenses c.Account Number 570 Maintenance of Station Equipment d.Account Number 571 Maintenance of Overhead Lines Description of Intertie Facilities Substations Intertie facilities are located at five substations:Gold Hill,Healy, Cantwell,Douglas and Teeland.With the exception of Cantwell Substation the Intertie facilities consist of additions to existing utility owned substations.Cantwell is a new tap substation feeding dis- tribution load and is considered an Intertie facility in its entirety. 62/2APA MP/D7 Specific Intertie facilities at the five substations are generally des- cribed as follows: Gold Hill Healy Cantwell 62/3APA MP/D7 100 MVA,138-69-13.8 kV Transformer 13.8kV Static Var System,5 MVAR Reactive to 33 MVAR Capacitive SVS Building Sequence of Events Recorder Remote Synchronizing Communications SCADA/RTU 138 kV Main and Transfer Bay with Line Exit 138 kV Circuit Switcher 33.3 MVA,138-12 kV Transformer 12 kV Static Var System,33 MVAR Reactive to 22 MVAR Capacitive SVS Building Douglas Line Relaying,Control and Metering Gold Hill Line Backup and Sparing Breaker Relaying Fault Recorder and Sequence of Events Recorder Remote Synchronizing Communications SCADA/RTU 345 kV Line Tap &Disconnect Switches 161 kV Circuit Switcher 5000 kVA,138-24.9 kV Transformer 24.9 kV Vacuum Reclosers 24.9 kV Bus,Structure and Line Exits Transformer,Metering,Relaying and Control Panels 24.9 kV Circuit Relaying,Control and Metering SCADA/RTU .

The foundations are one of two general types:driven H-piles or rock anchors.Whenever the underlying material would not allow the installation of H-piles,rock anchors were used.Several different types of rock anchor foundations were used,including threaded rebar grouted or epoxied into the rock through precast concrete blocks,threaded rebar grouted,or epoxied through the base of a pad and pier foundation, anchor bolts grouted into rock through cast-in-place concrete blocks and guy anchors grouted into rock.The rock anchors may penetrate through overburden from 1 to 30 feet deep before entering solid rock or they may be installed in material capable of resisting the required loads. The conductor is twin non-specular 954 MCM ACSR in a horizontal bundle configuration.The line is insulated with 18-unit strings of clevis type porcelain suspension insulators.The overhead ground wire is 7 strand 3/8"galvanized EHS steel.The phase conductors are not transposed.Maximum conductor temperature is 143.6°F. A complete set of "As-Built"drawings are available.These include the construction lists,construction drawings,plan and profile and access drawings.The construction list is the key to all the physical aspects of the line.It references location,span,line angle,foundation type, 62/SAPA MP/D7 2.0 2.1 2.1.1 2.1.2 structure type,guy assemblies,insulator-hardware assemblies,shield wire and conductor accessories including warning spheres,and sag tension data for the complete line. SUBSTATION MAINTENANCE PROGRAM Definitions of Maintenance Tasks Visual and Operational Inspections A visual inspection is a quick check of equipment status without disturbing operating conditions.It involves the use of sight to detect damage or change in the visual picture as well as reading of gauges; smell to detect burned insulation or oil;hearing to detect unusual noises of static,arcing or vibration;feel to detect abnormal heating of circuit breaker,recloser or transformer. An operational inspection is a check of the proper operation of the equipment by physically operating the equipment after securing permis- sion to do so.This includes tap changers under load equipment,circuit breakers,circuit reclosers and switches.Circuit breakers,reclosers and switches will of necessity be removed from service for this inspection.Tap changing under load equipment and voltage regulators may be operated within certain limits without being removed from service.This inspection also includes visual inspection. Minor Inspections Minor inspections require that the equipment be removed from service and worked on under a safety clearance.It requires visual and operational inspection,electrical testing,cleaning,etc.,but does not require internal inspection of circuit breakers,transformers,load tap changing equipment and circuit reclosers.It includes internal inspec- tion and minor repairs to transformers that do not require removal of 62/6APA MP/D7 the insulating oil or pulling the core and coils from the transformer tank. 2.1.3 Major Inspections,Repairs and Overhauls Major inspections require that the equipment be removed from service and worked on under a safety clearance.It includes visual,operational and minor inspections.It requires the internal inspection of,circuit breakers,circuit reclosers,and extensive internal inspection or repair on power transformers and load tap changing equipment that requires the removal of the insulating oil. 2.2 Maintenance Details 2.2.1 Main Transformers 2.2.1.1 Visual and Operational Inspections a.Read and record maximum and present temperature of top oil and windings. b.Read and record nitrogen cylinder pressure and nitrogen gas blanket or pressure-vacuum gauge. ec.Read and record combustible gas monitor. d.Check operation of cooling equipment. e.Check thermal breakers or fuses on cooling equipment. f.Check oil level;is it consistent with temperature? g.Check for oil leaks,chipped or broken porcelain'on bushings or lightning arresters,evidence of heating at connections. 62/7APA MP/D7 h. i. 1.

Two items of special equipment will,however,be needed.These are a 50-ton hydraulic jack for structure leveling and a conductor cart for conductor or spacer repair if the helicopter method of positioning the linemen is not adopted. MAINTENANCE RECORD KEEPING Maintenance record keeping is important from the standpoint of proving maintenance for warranty considerations,providing a basis for normal operation and to detect or predict a change in equipment which will require major maintenance or predict oncoming failure.A copy of the substation maintenance reports should be kept in the control house files,a copy maintained in the main file of the utility performing the inspection and maintenance with a copy being provided to APA. ACCOUNTING PROCEDURES Costs associated with inspections and maintenance should be kept by account numbers.General FERC accounts are given in Section 1.1. Each individual utility should develop a breakdown of these costs according to their present practice or needs.Accounting by substation and piece of equipment is desirable to determine the reliability of that equipment and its maintenance. -71- eA Imq@ ama temrinn 2.4 Spare Parts Furnished by APA except asterisk (*)items which are recommended but not furnished.Spare parts are to be maintained for

It should be noted that the majority of the problems can be identified by aerial patrols.However,it must be recognized that it may be necessary to make a ground or even a climbing inspection to determine -52- 62/52APA MP/D7 3.1.2 the extent of the problem and determine the required repairs or corrections. Patrols Patrolling is a commonly accepted term defining the inspection of overhead transmission lines.There are three types of patrols normally used: a.Routine b.Special ec.Emergency A routine patrol is defined as a regularly scheduled visual inspection of the line for the purpose of determining its condition and its ability to perform its load carrying capability without interruption and to assure safety of the public.The patrols may be either aerial by a fixed wing or helicopter aircraft,or a ground patrol. A special patrol is a non-scheduled visual inspection of the line performed after there has been a momentary interruption or severe weather condition in the vicinity of the line.These special patrols are usually performed at the direction of the power system supervisor to assure that the line did not experience serious damage which would require repairs to maintain continuity of service.The patrol should be aerial and performed as soon as possible after the occurrence. An emergency patrol is also a non-scheduled visual inspection of the line and is performed when there is an apparent permanent fault on the line and the protective circuit breakers have locked out.These patrols are performed at the direction of the system supervisor on an emer- gency basis.Emergency patrols should always be aerial if weather permits flying and may require covering the entire line section. -53- 62/53APA MP/D7 3.1.3 Although most serious line damage and material failures can be identi- fied by a trained observer during an aerial patrol of the transmission line,other damages and structure problems may only be determined from a thorough ground level inspection.These problems would include movement of the foundation pilings or anchors,movement of the X-frame support clamp on the piling,excessively tight or loose guys, guy yoke shear bolt failures,loose or missing anchor bolts,broken or loose ground connections to the structure,indication of structure failure at welds and joints,ete.All such problems must be identified at the earliest possible date and proper corrective action taken in a timely manner. Experience and knowledge of the terrain to be traveled will identify the most effective and economical time of year to do the ground patrol. There are soft tundra sections of the line that should be patroled during the winter months by using snowmobiles for crew transportation while other sections should be patroled during the summer months when the pile clamps and anchors are clearly visible without removing snow. Regardless of the time of year,a support helicopter will likely be required to move the patrol crew. Complete records of all patrols shall be maintained,including elapsed time required for both aerial and ground patrols.A suggested form for patrolsis included in this report as Appendix B. Climbing Inspections A combination of aerial and ground patrols will identify many line problems.Problems resulting from poorly fabricated materials, improper installation,loose hardware or deterioration can only be identified through a close inspection that requires the climbing of the structures.In addition the items that can be identified by a patrol,a climbing inspection will identify corrosion,deterioration,damage and loose or missing parts. -54- 62/54APA MP/D7 Climbing inspections are an essential part of the operation and main- tenance program of a transmission system;and because of the cost involved,the length of time between inspections should be optimized. They must be complete and thorough.Special climbing inspections may be required occasionally as directed by the system supervisor to verify fault locations as identified by oscillograph operations. Climbing inspections should be performed by a three-man crew con- sisting of a working foreman,a journeyman lineman and a groundman or an apprentice lineman.The frequency of such inspections is not standardized within the utility industry,but most utilities do make a climbing inspection of 100 percent of the structures within the first five years after they are placed in service.Because of the remote location where it will seldom be observed by personnel of the partici- pating electric systems and in an area that will subject the line to severe weather conditions,the line shall have a climbing inspection equal to 20 percent of the structures during each of the first five years of its service life.If the damages and material and construction errors and omissions are minimal then subsequent climbing inspections could be performed less frequently. A number of utilities are developing helicopter procedures to place a lineman in a working position on either the structure or the conductor with the line energized.Due to the time consuming labor to install and remove the detachable ladders,it is recommended that the helicopter procedures be investigated prior to beginning the climbing inspections. Adoption of these methods would require leaving the detachable ladders in place on the upper portion of the X-structures.This should not create a problem nor a code violation.It would require a crew composed of more linemen and probably no groundmen in order to utilize the helicopter efficiently. Tools required to perform a climbing inspection include structure ladders,hot sticks with a universal head,mirror,ratchet wrench and -55- 62/55SAPA MP/D7 3.2 3.2.1 torque wrench.Extra locknuts for the structure bolts and cotter pins shall be carried by the inspection crew to replace those that may be missing. Climbing inspections shall be scheduled during the summer months when the light and working conditions are better for identifying problems and when thorough ground line inspection of the structures can be made.If the helicopter procedure is used,the ground line inspection including checking the foundations,pile clamps,down guys and anchors,grounds and danger signs should be performed by a companion ground patrol. While climbing,all structure joints shall be thoroughly examined and the tightness of the bolts checked by the use of a torque wrench and any missing locknuts replaced.A thorough inspection of insulators and conductor hardware shall be made using a mirror on the hot stick to check areas not visible from the structure.Insulators shall be inspected to detect any that are broken,cracked,dirty,or flashed.Conductors and spacers shall be inspected in both directions from the structure for mechanical or electrical damage.All clearances of conductors and shield wires shall be checked.After the completion of the inspection of each structure the complete details of the findings and/or repair shall be entered on the Daily Line Crew Report Form (copy attached as Appendix C,complete with instructions). Line Maintenance Tasks General A transmission line of good design,constructed to specifications with materials that have been manufactured with a high degree of quality, seldom requires major repair.Since this line is in an area of severe weather conditions some adjustment or replacement of components may be required.In addition to weather,maintenance and repair of the line normally results from materials failure,inadequate construction,or from damages caused by third parties.The intertie was designed with -56- 62/56APA MP/D7 3.2.2 these factors in mind,and the line's ability to maintain a high degree of reliability was a major consideration. Conductor and Shield Wire Problems associated with conductors and shield wires are generally caused by external sources and may include: a Complete wire failure b.Frayed,birdeaged,burned,or broken strands Cc.Foreign objects d.Uneven tension e.Excessive sag f.Impaired clearances g-Failures at splices or connections Most conductor problems can be identified by aerial patrols and the majority of them deserve immediate attention.Defective conductors resulting from manufacture or damage during construction should be identified before the line is placed in service.However,damage that may result from the elements or third parties can occur at most any time during the life of the line.Frayed,burned or broken strands of conductor must be promptly repaired.If only the aluminum strands are damaged,then a repair sleeve would restore the conductors'ampacity and mechanical strength.In the event the steel core is damaged as well as the aluminum strands by gun shot or some other cause,then the conductor must be cut and a full tension compression splice installed. -57- 62/STAPA MP/D7 3.2.3 Uneven tensions,excessive sag or impaired clearances are often caused by guy or anchor failures or some structure problem.These conditions need close attention and early identification of the cause so that necessary corrections can be made and a line failure avoided. Conductor and Shield Wire Hardware All of the hardware is mechanical in nature and depends largely on bolts,nuts,pins and cotter keys in order to perform its function.If properly installed the hardware requires little maintenance,although it must be thoroughly inspected during patrols and climbing inspections. Some items that commonly require attention are: a.Damaged or out of alignment dampers or spacers b.Deformed or out of lay armor rods ce.Damaged or out of alignment corona rings d.Rusty or loose shackles,clevises,clamps and associated hardware and missing cotter keys and nuts e.Damaged or missing aircraft warning spheres. Many of these problems can be identified by aerial patrols.However, the deterioration of hardware will only occur over a long period of time;and detection can only be identified through a climbing inspec- tion.Any misalignment must be promptly corrected.Deformed or out of lay armor rods and improperly aligned corona rings can be a source of radio noise;and because of relatively low radio signal strength in the area of the line,these problems must be promptly corrected.The warning spheres serve an important air safety function and must be kept in good condition.° -58- 62/58APA MP/D7 3.2.4 3.2.5 Insulators Insulators are a critical item in the effective operation of a transmis- sion line.They are subject to damage from lightning flashovers,power arcs and vandalism.Insulator problems may be identified as: a.Chipped,cracked or broken porcelain b.Cracked,rusty or worn metal caps and cotter keys c.Out of vertical alignment d.Excessive contamination e.Flashed over Any damage to the insulators will not be as critical during the years that the line is operated 138 kV since the string of 18 insulators required for 345 kV operation is twice the number required for 138 kV. Unless there is a question as to the mechanical strength of the insulator string,any damaged need to be replaced on an annual basis until such time that the line is operated at 345 kV.After the line is operating at 345 kV,it is recommended that each damaged insulator be replaced as soon as practical after discovery using hot-line work methods. Structures and Foundations The structures of the Intertie should require little maintenance during the life of the line.Climbing inspections during the first five years operation should identify and correct most of the problems that may occur as the result of missing bolts or locknuts,or misalignment of structure members. -59- 62/S9APA MP/D7 The pilings which support the structure may be subject to frost jacking, and adjustment of the structure base connection to the piling may be required.Maintenance crews will need a 50-ton hydraulic jack to support the tower and allow for tower leg clamp adjustments.It may be necessary to cut the ungalvanized leg base connection bolts off with an acetylene torch.When tower leg clamps need to be adjusted all bolts should be replaced. In general,foundation inspection should include: a.Pile clamp shippage b.Pile clamp bolts,nuts and locknuts loose or missing c.Pile jacking due to frost d.Concrete cracking e.Anchor bolt nuts loose or missing f.Rock bolt nuts loose or missing ge Bitumastic coating damage Structure problems which may need attention are: a.Structure out of plumb in either direction b.Bolts,nuts,locknuts and cotter keys either loose or missing Cc.Signs and markers,damaged or missing d.Deteriorated or cracked welds -60- 62/60APA MP/D7 3.2.6 3.2.7 Structure foundations are a major item to inspect during the annual ground patrol. Guys and Anchors The tubular X-towers were guyed to permit unbalanced longitudinal loads under normal or broken conductor conditions and,thus,the longitudinal guys are an important part of the structure integrity.The guys and anchors should be inspected annually during the ground patrol of the line. The guy assemblies for the tubular X-tower are designed with a guy yoke shear bolt connection to eliminate failure of the guys due to increased tensions caused by frost jacking of the leg piling. Failure of a shear bolt will require adjustment of the guy assembly, near the anchor,to allow replacement.The guys must then be retensioned.They must also be retensioned if they become loose due to upwarded movement of the guy piling. In any event wherever there is an adjustment made,new elevations of the foundations and anchors shall be taken for comparison with the as- built conditions.Through this comparison it will be determined whether a foundation or anchor still has the capability required or whether further maintenance is necessary. Grounding Grounding was installed only at towers where the foundations were on rock and involved rock anchors.No grounding was done on pile foundations since the piles will provide for the lowest resistance possible. -61- 62/61APA MP/D7 3.2.8 3.3 There are no ground rods,and therefore,the only inspection required should be as follows: a.Ensure tight connection of wire to tower base b.Check for broken or missing wire Rights-of-Way The maintenance of the rights-of-way of the Intertie should be minimal during the life of the line.The coniferous trees,native to the area,are slow growing and additional tree cutting or trimming should not be required during the first ten years of the line operation.However, some of the structures may be located in flood plains or adjacent to streams which may change their course and require the construction of gabions or other means of water diversion.Similarly,structures that may be located in heavy snowfall areas may need to be protected from snow slides.Although these problems are expected to be minimal,line patrols should be alert to these problems and any necessary corrective action taken as soon as possible. Transmission Line Maintenance Schedule In order to maintain the integrity of the Intertie line,regular inspec- tions and patrols must be made.The following schedule is established for this purpose: a.Routine Patrols -Aerial -January,April,July,October Ground -Once per year b.Special Patrols -As Required ec.Emergency Patrols -As Required 62- 62/62APA MP/D7 d.Climbing Inspection-20%of line each year for first 5 years, then re-evaluate based upon findings of first 5 years. 3.4 Spare Parts In order to properly and efficiently maintain the Intertie,a quantity of spare parts needs to be kept on hand.They should be cataloged, labeled,and kept within a secured area.Due to the size of some items and infrequency of need,a central location should be selected for the larger,bulkier materials.The following is a list of those items:| a.Towers -Store at one central location Three Type A Towers -(waist up plus the following legs) 1 -70'leg (complete with guy yokes) 1 -75'leg 2 -80'legs 5 -85'legs 2 -90'legs Two Type B Towers -(waist up plus the following legs) 4 -80'legs (complete with guy yokes) 2 -85'legs 2 -105!legs One Type HA Tower -(waist up plus the following legs) 1 -70'leg (complete with guy yokes) 1 -85'leg 2 -90'legs One Type C Tower -80' Two Type D Towers”-80!

The only spare parts outstanding are those for the transformers at Teeland,Douglas and Gold Hill.By letter to each of the three substation owner'sdatedApril10,1985,we advised of the estimated arrival date,approximate quantity,weight,space required,and recommended storage.We have received comments from al]three substation owners regarding their preferred handlingoftransformersparepartsandwillactaccordingtotheirindividual desires. With respect to transmission line material and spare parts that are currently stored at Eklutna,we recommend they remain stored there with the possibleexceptionofsomeinsulators. The operation and maintenance activities of the Intertie requiring APA sparematerialcanbeclassifiedasminorormajoractivities.A minor activitywouldbereplacementofbrokeninsulators.A major activity would be loss ofaSpanofconductor,shield wire,a tower or any combination or multiple of the three. Relative to minor maintenance,APA has four kinds of insulators at Eklutna.They are 15 Kip for shield wire,20 Kip for tangent structures,30 Kip and 40Kipforothertypesofstructures. Mr.Davie R.Eberle May 16,1985 Page 2 of 2 We recommend 4-15 Kip,200-20 Kip,100-30 Kip and 100-40 Kip insulators be stored each at Healy and Douglas substations.This amounts to about 3palletsofspace.The remaining insulators should be kept at Eklutna in reserve.These insulators could be used as required without the need to coordinate with the APA marshalling yard. Relative to major maintenance,APA would probably be involved due to theiroriginalconstructionexperience.We believe material response to such amajorrepaircouldbestbecoordinatedbyasinglepointofcontactattheEklutnayard.Further,by the time such a repair effort was organized,the parts needed could arrive from Eklutna.Therefore,Eklutna storage of major intertie material and spares appears to enhance possible future repairs rather than pose any difficulty. The above coupled with limited storage space at the substations;the possibility of damage or loss of limited supply components;and the question of whether to store one of a kind components at Healy or Douglas leads us to recommend that all major spares remain at Eklutna. Kindly advise if you desire additional information or assistance.
