("STG") to perform preliminary design criteria and cost estimate to construct a power line for Unalakleet Valley Electric Cooperative ("UVEC") from the new wind farm site to the current underground site at the airport. STG will be constructing a new 12.47 kV (energized at 4160 V) distribution line between the new UVEC wind farm and the current underground location at the Unalakleet Airport. The line will follow the land fill road from the wind farm site to the existing FAA line; this section of line is approximately 1.85 miles. The FAA line will then be replaced with new poles and conductor and continue to where the line currently goes underground at the Airport, this section of line is approximately 0.80 miles. A fiber optic cable will be attached to the power distribution line at the wind farm and continue from the Airport location to the diesel power plant. The purpose of this report is to outline the design criteria that were used to generate an estimated cost of construction of the distribution tie line. This includes loading criteria, strength factors, clearances, conductor and equipment for overhead construction. The design was based on governing codes. Since UVEC is currently owned and operated by Matanuska Electric Association (MEA) wherever possible, use of MEA standard materials and methods will be used. The recommended overhead construction utilized for the tie line is 12,47/7.2 kV — #2 ACSR conductor, energized at 4160/2400 V. A robust design is recommended in anticipation of the high winds on the unprotected coastal route near Unalakleet. 2 Line Configuration 2.1 General Routing The general routing of the line in Unalakleet will be as follows. The first segment will be along the wind turbines for a distance of approximately 1,800 feet. At each turbine it is proposed to have a pole with a three phase transformer bank to step-up the generation voltage of 480 V to the distribution voltage 4160 V. The next pole at each turbine will be a pole with a group operated air break switch. This will allow each turbine and transformer bank to be isolated from the system. After the wind farm site the pole line will follow the existing Land Fill road for approximately 1.85 miles. STG is currently in the process of obtaining easements/permits to have the line in the road right-of-way. The line will then tie into the existing FAA line. At this point the line will be upgraded back to the underground section at the airport. The line is currently a delta system, with a grounded wye to delta pad mounted transformer at the airport. It is proposed to relocate this transformer from the airport to where the tie line intersects the FAA line. The approximate length of the FAA line to be upgraded is 0.80 miles. 1 electric Power Systems MC. _ Co+tsu(ling Engineers K CONCEPTUAL DESIGN REPORT UNALAKLEET WIND PROJECT TIE LINE Communications will be needed from the new wind farm to the existing diesel plant. B2 Networks will be designing the terminations, splicing, cabling, junctions, and vaults. EPS will design the line to carry the fiber optic cable. The routing of the fiber optic line will follow the power line from the wind farm to the underground site at the airport. From there it is proposed that the fiber optic cable utilize a spare conduit under the east -west runway and continue underground to the power plant. STG will be responsible to obtain a proper construction easements and permits from the appropriate parties for the line to be constructed. The proposed route is shown in the Appendix. The design criteria for overhead construction are discussed in Section 2.3. In general, the overhead line design criteria offered for this location meets National Electric Safety Code (NESC) Heavy loading district and Grade "B" construction criteria, with additional extreme wind and heavier ice conditions added. 2.2 Cost Estimates —Assumptions and Discussion The total construction cost is estimated to be $1.4 to $1.6 million. A detailed breakdown for the estimate is included in the Appendix. Note that these costs are for construction only. No engineering, surveying, permitting, easements, and O&M costs are considered in this estimate. The communication cable utilized for the clearance and pole strength calculations was a 24 count figure-8 fiber optic cable. B2 Networks specified a Corning ALTOS Figure-8 cable. This particular cable has a built in V EHS steel messenger. The installation and material cost of the cable was in the project construction cost estimates, However the cost of terminations, plant equipment, vaults, slack storage units, and other miscellaneous was not included. The specific material and labor that was included was cable (along pole line and underground to power plant), pole attachment hardware, guying, anchors, trench and conduit. For the overhead system, the poles that were chosen for consideration were based on strength and clearance. The typical poles are 45 foot class 2 poles for the land fill road section, and 40 foot class 2 poles to upgrade the FAA line. Since MEA currently owns and operates UVEC, MEA construction units were used for this estimate. With very limited geotechnical data a pole foundation with gravel back fill has been included. This type of backfill has been used on other projects in Western Alaska. it is assumed that local sources are available for this type of backfill. If future geotechnical studies are conducted and such studies indicate the need for a pile foundation, it will be added for the final design. Ruling spans were selected based on terrain, loadings, as well as proposed poles heights and conductors. Pole clearance and strength calculations can be found in the Appendix. Due to the line proximity to the Unalakleet Airport, it may be determined during the permitting process that pole sizes may need to be changed or the line may have to go underground. These changes may affect the construction cost of this project. Clearing was not included in this estimate. There may be incidental clearing needed along the route. 2 electric Power S s' P�5Coasu!lfng Engineers CONCEPTUAL DESIGN REPORT UNALAKLEET WIND PROJECT TIE LINE 2.3 Design Standards 2.3.1 Code Compliance All design criteria was developed using known environmental and climatic information for the project area, the C2- 2007 edition of the National Electrical Safety Code (NESC) and construction specifications outlined by the Rural Utilities Service (RUS) and Matanuska Electric Association (MEA). 2.3.2 Overhead 2.3.2.1 Clearances Clearances to ground and other installations will meet or exceed the requirements of the 2007 NESC. Typical NESC required clearances are as shown in the following table: Clearance Item Minimum Clearance Sag Criteria 7.2l12.5 kV (4160/2400 Vertical Clearances (NESC) Over Ground and Roads 18.5' 32°F, 112" Ice, No Wind, Final Sag OR 120°F, No Ice, No Wind, Final Sag* Over Communication Cables (carried on other supporting structures) 5.0' 32°F, 112" Ice, No Wind, Final Sag OR 120*17, No Ice, No Wind, Final Sag* Over Open Supply Conductors (carried on other structures, up to 22 kV to round) 2.0' 32'F, 1/2" Ice, No Wind, Final Sag OR 120°F, No Ice, No Wind, Final Sag* Communications Vertical Clearances (NESC) Over Ground and Roads 15.5' 32'F, 1/2" Ice, No Wind, Final Sag OR 120°F, No Ice, No Wind, Final Sag* 7.2I12.5 kV 416012400 V Horizontal Clearances NESC From Buildings No Wind Displacement) 5.0' 60°F, No Ice, No Wind, Final Sag From Buildings With Wind Displacement)-4.5' 60°F, No Ice, 6 sf Wind, Final Sag * Whichever criteria produces the greatest sag The NESC requires that power and communications have a 40 inch separation when mounted on the same supporting structure. We will design for a minimum separation of 54 inches, this dimension could change during the design when sag and tension of the power conductor and communications cable is determined. 2.3.2.2 Conductor and Structure Loading All structure and conductor loading meet the requirements of Grade 8 construction as detailed in the NESC. None of the structures are technically required to comply with Rule 250C in the NESC for Extreme Wind. However, due to the 120 mph wind rating the NESC has given this region of Alaska, EPS believes it is prudent to require the Plectric Power S st ems 3 ConsuI!!ng Engineers CONCEPTUAL DESIGN REPORT UNALAKLEET WIND PROJECT TIE LINE facilities to meet this requirement despite none of them being over 60 feet above ground level. As a result, the following loading conditions were used: • Grade B Construction • NESC Heavy (0°F, 0.5" Ice, 4 psf wind) • Extreme Wind (20°F, 0" Ice, 36.9 psf wind) • Extreme Ice (O'F, 1.0" Ice, no wind) • Low Temperature (-40°F, no ice, no wind) For the purpose of this report all pole depths were set to be 10% of the entire pole length plus an additional 4 feet to enhance freeze -thaw cycle stability. 2.3.3 Additional Project Costs In addition to the construction cost of the line itself, other costs have been identified for this project. These costs have not been included in the attached construction cost estimate. A brief description of each follows. Bird Flappers, $7,800. On other projects in Western Alaska, US Fish and Wildlife (USFW) has asked for 3 bird flappers per span to be installed. USFW believes these bird flappers will reduce the amount of bird strikes on power lines. This report did not include any communications with USFW to see if bird flappers will be required. The permitting phase may dictate this. 4 lectric over sy tems P.�S iConsufting Engineers r CONCEPTUAL DESIGN REPORT 3 Appendix 3.1 Construction Cost Estimate DNALAKLEET WIND PROJECT TIE LINE Pieckric Pacer S s+fit ` MG PYS ConsulfingEngtncers 05/29/2009 ELECTRIC POWER SYSTEMS, INC.
