The alternatives have been identified in the Design Section Report and System Studies Report. The three primary alternatives are referred to as Tesoro Route, Enstar Route, and Quartz Creek Route. Based on the results of the preliminary design efforts and environmental evaluations, each corridor has a base route identified. These base routes are potential routes that have attributes that may allow the route to be ultimately permitted under an environmental assessment (EA) or environmental impact statement (EIS) process. The cost estimates for the environmental permitting efforts are based on the preparation of an EIS. For purposes of this report, the base routes will be the baseline estimates. Multiple alternatives to each of the base routes are also provided. Refer to the alternative corridor map in the map pocket for the locations of the routes. When referring to the map and in the route tables, please note for the link designations, the first two letters of each route delineate the overall route or area for a routing opportunity as follows: TS Tesoro Route ac Quartz Creek Route EN Enstar Route AN Anchorage Municipal Area This Economic Section Report provides an overview of the project cost estimates, a summary of the estimates, and a detailed breakdown of the various costs. The report is organized as follows: e Report Summary and Economic Section Overview - Introduction - Economic Section Report Overview - Summary of Estimates - Summary of estimates in 1996 dollars for each preferred base route and local alternatives inclusive of submarine, underground and overhead transmission, substations, reactive compensation, environmental permitting, rights- of-way, engineering and construction management - Tesoro Route - Detailed description of the base route and local alternatives - Enstar Route - Detailed description of the base route and local alternatives - Quartz Creek Route - Detailed description of the base route and local alternatives Overhead Transmission - Cost estimate breakdown by link Underground Transmission - Cost estimate breakdown by link Substations - Cost estimate breakdown by substation alternative Reactive Compensation - Cost estimate breakdown by device and application Environmental Permitting - Cost estimate breakdown for EIS, associated studies, and Pre- construction surveys e Rights of Way - Cost estimate breakdown by right-of-way and related permitting HLY 55-0198 (06/96) FINAL 120293-01/ab 1] e Appendices A-D - Supporting detailed documentation for transmission, substation and reactive compensation estimates. SUMMARY OF ESTIMATES The Southern Intertie has numerous technical challenges regardless of the route. The following discussions reflect some of the more economically significant assumptions applied to the cost estimates. OVERHEAD LINES ®@ The overhead transmission structure types are steel guyed-X and single pole steel structures in accordance with the Design Section Report and detailed in Appendix A in this document. SUBMARINE CABLES @ The submarine cable estimates were performed based on double armor (two protective layers of galvanized steel strands of same diameter and lay) for the entire circuit length and embedding the cables. The decision to double armor and embed is based on the operating environment in the Turnagain Arm and discussions with Pirelli. Additional discussion on this information is presented in the “Submarine and Underground Transmission Cable” section of this document, Appendix B, and in the Design Section Report. The recommended cable system at 138kV, except for the Bird Point crossing is 2 - 3 phase flat type SCFF cables. Since this system provides for two completely independent 3 phase circuits, embedment of the cables may not be as important, since if one circuit fails, the line could continue to operate on the other circuit. Since embedment is estimated to add significant costs to the installation, site specific Geotechnical investigation is recommended prior to finalizing a decision regarding embedment. At 230kV, 4 - 1 phase SCFF cables are estimated, with embedment. The recommendation to use the flat type three phase cables at 138kV is based on our conversations and correspondence with the manufacturer, NKT of Denmark, and with two utility users of the cable. Because installation of this cable type has been primarily in Denmark, it is recommended that a visit to the manufacturer and users of the cable be completed during the next phase of the project to confirm our previous discussions in more detail. The alternative to the three phase flat cable is four single phase cables, and we have included an estimate of project costs using this type of cable at 138kV, in addition to the flat three phase cable. HLY 55-0198 (06/96) FINAL 120293-01/ab 2 ®& The Bird Point Alternative was estimated using a different technology than the SCFF type submarine cable. We anticipate that it will be possible to set up in the Turnagain Arm and directionally drill towards either shore to place an HPGF type of cable system. @ After additional geotechnical investigations have been performed and the submarine, installation actually bid, we anticipate up to a 10% reduction (0.9 - 3.0 $M) in the cable material price. LAND UNDERGROUND CABLES ® All anticipated underground high voltage cable installations are assumed to be XLPE type. This is reliable type of technology and has the lowest costs. SUBSTATION @ The substation estimates are based on the Design Section Report and the General Arrangements located in Appendix C of this document. @ The termination points for the Southern Intertie were selected for estimating purposes. Actual final terminal (substation) locations may vary in the Anchorage area. REACTIVE COMPENSATION @ Reactive compensation will be required for all scenarios of the Southern Intertie to facilitate steady state power transfer, dynamic stability during system disturbances and to control capacitance of high voltage submarine/underground cables. Additionally, construction of the new transmission facility will require compensation of the existing 115kV Intertie for the same reasons. Our cost estimates include appropriately sized devices for both new and existing facilities. The high voltage underground or submarine type of cables require shunt connected reactors. Generally speaking, the higher the voltage and the longer the cable run, the larger (MVAR) the reactor has to be to control the (higher) capacitance. Also, the existing 115kV Intertie would require shunt connected capacitor banks augmented by a Static Var Compensator (SVC) or a Thyristor Controlled Series Capacitor (TCSC) Bank. Estimates are provided for both scenarios; however, the TCSC offers superior steady state and dynamic capabilities and is the preferred choice. It should be noted, a significant capital cost savings of approximately $3M can be made by eliminating the TCSC, if it is determined that some underfrequency load shed can be tolerated. The extent of load shed is highly dependent on the generation mix at the time of a system disturbance and on the ability to be able to very quickly provide transfer trip of at least one HLY 55-0198 (06/96) FINAL 120293-01/ab 3 Bradley Lake unit. The Bradley Lake transfer trip underfrequency trip scenario will require further investigation during the next phase of the project. ® The reactive compensation estimates are based on the System Studies and Design Section Report and information detailed in Appendix D. ENVIONMENTAL PERMITTING ® Each of the three major potential route for the project present significant challenges to successfully securing a permitted route based on meetings with the public, affected agencies and a review of previous study correspondence. It has not yet been determined whether an EA (Environmental Assessment) or an Environmental Impact Statement (EIS) level of effort will be required to comply with NEPA (National Environmental Policy Act) requirements. Cost estimates included in this report are based on an EIS level of effort. = As compared to the effort required for a typical EIS, the project will require additional studies or effort in the following areas (please refer to the Environmental Permitting Section for more detail): Anchorage Urban Study Additional Data Collection Additional Public and Agency Meetings to Facilitate the Decision Process Additional Mitigation Studies PRE-CONSTRUCTION SURVEYS ® Prior to construction and potentially before agency approval on the selected alternative, a number of compliance studies are required. These include Section 106 (cultural) and Section 107 (biology). In addition, a Construction, Operation and Maintenance (COM) Plan would be prepared. The final element of environmental studies includes preparation of EAs (if needed) as well as other permits (e.g. Section 404). HLY 55-0198 (06/96) FINAL 120293-01/ab 4 RIGHT-OF-WAY AND RIGHT-OF-WAY ACQUISITION To secure the requisite project right-of-way, two major acquisition processes will occur: e __ Permit acquisition to secure CEA’s transmission line rights to exist on local, state, and federally administered lands; and e Private land easement acquisition to secure CEA’s rights to exist on private lands crossed by the transmission line. The variation of project right-of-way and permit acquisition costs among the three primary ° alternatives is a direct function of the agency lands crossed that require permitting, as well as the amount of private land crossed by the route. The direct cost of subsequent land value of the lands encumbered by the easement on those parcels. Indirect costs are directly related to the number of parcels to be acquired, and the labor and expense costs associated with easement acquisitions. FIBER OPTICS The preliminary design and design criteria as presented in the Design Section Report do not provide for fiber optics. However, based on our experience with similar projects, we have estimated the cost of adding a fiber over the various routes and have summarized those costs below. Costs for the addition of fiber optics to the Project are not included in the overall Project costs as summarized elsewhere in this Report. If the addition of fiber optics is desired to be added to the Project, it is recommended that it be included in the requirements for the final design.

Significant substation modifications, including additional reactors would bé required. The base route departs the Point Woronzof Substation via submarine cable and crosses to Fire Island. The cable makes landfall on the north end of the island, goes to overhead construction, then back to submarine type cable on the south end. It again makes landfall near Point Possession on the Kenai Peninsula. At this point, the line has a small reactor station and proceeds down the coastline to Bernice Lake Substation via overhead with the exception of Captain Cook State Park, which is estimated as underground.

The underground continues to about Potters where it transitions into submarine type cable to cross the Turnagain Arm. The submarine cable makes landfall on the Kenai Peninsula near the Burnt Island Creek area. The submarine cable is then transitioned into underground type of cable to a point near Big Indian Creek. At Big Indian Creek there would be a transition station with reactors and go back to overhead construction the rest of the way to the terminus at Soldotna.

At Bird Point, alternative routes crossing the Turnagain Arm from Bird Point to the Snipers Point area and proceeding south along Sixmile Creek to rejoin the existing line near Hope Junction have been estimated. The crossing of the Turnagain Arm at Bird point has been estimated for both overhead and submarine crossing alternatives. The submarine crossings has been estimated using directional boring techniques to enable the installation of an HPGF cable system. ROUTE DESCRIPTIONS AND COST ESTIMATE SUMMARIES The following tables more fully describe the base route for Quartz Creek Route in addition to the identified alternatives and their associated costs. Also, please refer to the Alternative Corridors Map located in the map pocket at the back of this report to assist the reader in identifying specific links that constitute the route and alternatives: HLY 55-0198 (06/96) FINAL 120293-01/ab 1 TABLE QC 01 QUARTZ CREEK ROUTE Link/, tion Inf Link Code | Total Length Location Type of Facility (Miles) Substation N/A University Substation 138kV: One bay extension of existing main and transfer layout. 230kV: New 230kV 4 Breaker Ring Bus.

These estimates are based on the preliminary designs presented in the Draft Design Section Report for this project. The estimates are organized by route and local alternatives similar to the route estimates contained in an earlier section of this report. Please refer to the route sections for link descriptions. The per mile line costs have been adjusted in some cases to allow for conditions not anticipated in the per mile line estimate. These cases include: e Link TE.D.40 across Fire Island. Costs have been increased because of access. e Links QC.C.30, QC.E.40, and QC.F.50 have been reduced because a reduced clearing effort is anticipated in these areas. e Links QC.D.40 contains a line item for temporary installation and removal of a line during construction of the double circuit steel line. Please note that guyed X structures were selected for cost estimating because they were practical for the locations in which they were applied and have costs which are comparable to wood pole H-frame and guyed vee structures. The type of structure chosen for final design will be determined after a detailed investigation of the route, agency requirements, and other factors. The following table summarizes salient information on the different overhead line designs.

This cable is expected to perform well in the operating environment of Turnagain Arm. The exception to this is the Bird Point Alternative where installation of a high-pressure gas-filled (HPGF) system, using directional drilling as an installation technique, is recommended. Cross-linked polyethylene (XLPE) cable is recommended for use on all land based underground cables. XLPE is not recommended for use as a submarine cable because it is not a commercially available product in the spliceless lengths and voltages required for this project. Two types of fluid-impregnated paper-insulated cable are viable for this project. One is self contained fluid filled (SCFF), a pressurized system that is a proven technology used for submarine cables worldwide. The second type of cable that warrants further investigation is a flat three-phase self- compensating design from NTK, Denmark. This design would provide the lowest installed cost and would provide two completely redundant three-phase circuits (vs. four single-phase cables for the traditional SCFF type cable). This unique capability may further influence the recommendation for embedment pending additional geotechnical evaluation. Cost data has been developed for each type of paper-insulated, fluid-impregnated, self-contained fluid-filled (single-phase cables) and self-compensating fluid-filled (three-phase cables). As a result of our preliminary engineering investigations completed during Phase I of the Project, we are providing cost estimates based on the use of the following cable types: 138kV - Bird Point Crossing 138kV & 230kV Land (Underground ) HLY 55-0198 (06/96) FINAL 120293-01/ab 1 SUBMARINE CABLE The cost estimates have been made assuming that double-armored cables will be embedded into the Arm’s bottom using a water jet assisted cable plow. The decision to use this method for the estimates is based on our information about the potential crossings and the recommendations of Pirelli-Jacobson’s Brian Jacobson (see letter in Appendix B). We have also provided a non- embedded cost estimate for each of the cable types we considered by reducing each embedment estimate by an appropriate amount, route dependent. The embedment cost is for embedment only and the associated mobilization and demobilization of all required equipment is covered separately. There are possible exceptions to using embedment for selected portions, or possibly entire lengths, of each alternative. Geotechnical and bathymetric evaluations could indicate that there may be areas where embedment is not needed. It may further indicate that additional armoring (rock armoring) is justified along part of the route (or link) where it is not feasible to embed the cables. Since significant field work is required and this data is to be obtained during the next phase of the project, we have opted to consider direct enbedment of double-armored cable along the entire route of each alternative to calculate the estimates. Based on the available information at this time, the reasons to embed cables are: e Scouring and abrasion of armor in the Point MacKenzie-Point Woronzof cable field has damaged armor on some of the existing cables, causing them to leak and subsequently be taken out of service. ° Pirelli-Jacobson recommends the embedment of armored cables due to the operating environment, based on their experience in the area. ° Embedment may reduce the risks of cables being damaged by anchors and moving boulders and changing Turnagain Arm bottom profile. ° Buried armor suffers significantly less corrosion and wear. To determine areas where embedment is not practical or is unnecessary, we recommend that further evaluations of the sea bottom’s surface and subsurface be conducted. These include evaluations by side-scan sonar, sub-bottom sonar, geotechnical drilling, and investigation of the bathymetry of the Turnagain Arm. These evaluations will help determine where rock armoring is necessary along portions of each link. The reasons not to embed cable in certain areas include: ° The bottom is too steep to use the embedding plow. ° The bottom is so soft that the cable will embed itself. ° Severe currents in the Arm cause the bottom to shift enough to uncover the embedded cable in a short time. e Bottom conditions are too hard (rocky) to embed cable. ° The additional cost of embedding already-protected (armored) cables may be considered excessive. HLY 55-0198 (06/96) FINAL 120293-01/ab 2 e Ice scour and/or boulder movement is so severe that embedment at a depth of 10 feet is not sufficient to prevent damage. Should the non-embedded approach be selected for part or all of an alternative’s length, the addition of rock armor over the double armor of the cables should be considered. Rock armor is an additional layer of armor consisting of wires that are typically larger in diameter than the wires of the underlying armor. The rock armoring is applied with a shorter lay than the normal armor wires. Its purpose is to provide additional protection against damage by external forces, such as anchors or boulders, and to support the cables when laid over obstructions or when bottom shifts suspend the cable over a portion of its route. This additional armor may double the weight of the cable and makes the cable stiffer and more difficult to handle. Rock armoring may be applied to selected sections of a continuous cable. The cost estimates are based on a 1,000-foot spacing of cables along the bottom. The Coastal Pilot (reference the Design Section Report) identifies an anchorage just north of Point Possession, near several of the possible cable routes. A final decision on the spacing should be made after the recommended geotechnical and bathymetric evaluations are completed. However, the actual spacing is expected to have little impact on the overall cost of the cable’s installation. For purposes of design and estimating we used 1-1000KMC per phase. This conductor size was utilized due to defined system load flows, dielectric losses, cable construction and ampacity calculations determined by assumed values of soil thermal conductivity, and probable subsurface geological features and profiles. Further geotechnical investigations will be required after a preferred route is selected to optimize the conductor size. This effort would be undertaken in the detailed design phase of the project. LAND UNDERGROUND CABLES All estimates for cables installed on land have been made using a manhole and duct system which is typical and usual for this type of application. Additionally, estimates assume that cross bonding of the cable’s sheaths as described in the Design Report. XLPE is the preferred insulation for land-based cables. This insulation material has proven reliability, is readily available, has the lowest losses and least maintenance requirements, and is the lowest capital cost. COST ESTIMATE SUMMARY Each of the following estimates is a compilation of the individual links and assumptions used to make up the cable costs of a particular route or local alternative. All cost estimates are in millions of dollars. Additionally, the following assumptions were used: HLY 55-0198 (06/96) FINAL 120293-01/ab 3 ° Landfalls were assumed to be within 1,000 feet of water’s edge. The reference to the 1,000 feet of conduit is in the Economic Report, Appendix B, sheet 2. The basis of 1,000 feet of conduit is that it is a typical length for these types of installations. The distance from shore’s edge to cable termination point could be as little as a few hundred feet up to 2,000 feet. Accordingly, 1,000 feet was used for estimating purposes. ¢ Geotechnical estimates includes marine survey, soil borings and soil thermal resistivity testing. ° Labor and expenses related to installation techniques are included in the labor item on the mobilization/demobilization line item. i ¢ Burial conditions for embedment costs are assumed to be without boulders or other significant obstructions. , e Installed cable cost for links in the Tesoro Route is $53.00 per cable foot and embedment cost is $14.00 per cable foot. ° Installed cable cost for links in the Enstar Route (EN.B.90) is $56.00 per cable foot and embedment cost is $14.00 per cable foot. e Installed cable cost for the Bird Point link is $176 per cable foot and embedment cost is $35.00 per cable foot. All cost data was developed from information supplied by Pirelli-Jacobson and Jacobson International. We also considered recently incurred cost of repair of CEA’s submarine cable systems. Subsequent to our evaluation of prices and development of methodology, Pirelli Jacobson’s Pietro Mondim reviewed our work and said that the higher costs per cable foot are justified for the shorter routes because fixed costs would be spread over shorter installation distances. Other items included in the section are a material pricing summary and a spreadsheet detailing the methodology to determine installation costs per cable foot.

I Es L r Page 1 SUBSTATIONS INTRODUCTION Modifications will be required to existing substations to terminate the proposed Southern Intertie. For the purposes of this report, alternate substation estimates have been prepared to include the University, Point Woronzof and International substations in the Anchorage area and the Soldotna and Bernice Lake substations on the Kenai Peninsula. In the EIS phase of the project, additional termination sites in the Anchorage area will be considered. This section will present the applicable substation cost estimates for the modifications necessary to terminate the Southern Intertie. Cost estimates for each substation are based on the conceptual general arrangement drawings contained in Appendix C and other applicable information as contained in the System Studies and Design Section Reports. Equipment vendors were contacted for equipment prices and shipping costs and constraints. The equipment prices used in preparing the estimates are based on this vendor information and are f.o.b. site. Future plans and additions for the substations were considered and accommodated in these estimates to the extent possible. The preliminary designs have also considered the addition of switches where appropriate to allow future expansion with minimal outages. Additional land purchase and/or expansions of the existing fence will be required for all proposed substation modifications. Land purchase prices are included in the right-of-way Section and were not included in the substation estimates.

HLY 55-0198 (06/96) FINAL 120293-01/ab 3 BERNICE LAKE SUBSTATION GENERAL The cost estimates for the Bernice Lake Substation are based on a new 115kV three breaker ring bus. The bus has been designed to not alter the existing access. The existing 115kV circuit breaker and voltage transformers will not be reused due to the length of outage required to perform the required modifications. The existing 115kV deadend structure and disconnect switch will be left in place and reused is shown in Figure SS-09, Appendix C. The existing yard must be expanded to the east for the addition of the Southern Intertie. Homer Electric Association (HEA) owns the property east of the substation to North Kenai Road. This area is adequate for the required modifications. 138kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 09. The proposed arrangement requires that additional property, approximately 215 x 185 feet in size, be included in the substation fence. Refer to the more detailed cost estimates contained in Appendix C and the Design Section Report for more information on the specific equipment required. 230kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 10, Appendix C. The proposed arrangement requires that additional property, approximately 235 x 185 feet in size, be included in the substation fence.

If the new station is not built at the time it is needed for the Southern Intertie, additional work will need to be done to the existing substation. The bay for the Southern Intertie can still be built in the location shown on Figures SS-11 and SS-12, Appendix C, but-a strain bus would need to be constructed to connect the bay to the existing substation. Additional costs would be incurred for site work, fencing, grounding, control building, etc. that would not be necessary if the new station were in place. These costs have not been estimated. 138kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 11. Cost estimates for the 138kV option assume that the proposed 138kV breaker-and-a- half station is in place. The general arrangement drawing of the proposed station furnished by CEA shows a bay designated for a future 138kV transmission line. As shown of Figure SS-11, this bay will be used for the Southern Intertie. 230kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 12. Cost estimates for the 230kV option assume that the proposed 138kV breaker-and-a- half station is in place. The general arrangement drawing of the proposed station furnished by CEA shows a bay designated for a future 138kV transmission line. As shown of Figure SS-12, this bay will be used to connect to a 230/138kV autotransformer via an overhead strain bus. The 230kV portion of the station will be constructed adjacent to the proposed station and will require that additional property, approximately 250 x 55 feet in size, be included in the substation fence.

The design takes advantage of unassigned future positions where possible. 138kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 13, Appendix C. Cost estimates for the 138kV option assume that the future 138kV bay shown on the general arrangement drawing furnished by CEA can be used for the Southern Intertie. 230kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 14, Appendix C. Cost estimates for the 230kV option assume that an entirely new 230kV station will be built to the east of the existing station. Proposed changes to the 230kV portion of the station completely utilize all available land within the existing fence. Future plans include the addition of another 230kV line to ML&P Plant No. 2 and a 230/115kV autotransformer. The configuration of the proposed 230kV additions is not easily adaptable to accommodate the future additions. For this reason, a ring bus expandable to a breaker and one-half has been proposed as shown on Figure SS-14.

This section presents the cost estimates for each of the possible transmission line routes. Please refer to the “Route Descriptions and Cost Estimate Summaries” section of this report for a listing of required compensation requirements for each Alternative identified. Equipment vendors and turnkey/manufacturer’s were contacted to obtain equipment prices, shipping costs and related construction costs. The pricing information is used in preparing the estimates in this section. Land acquisition and/or new right-of-way will be required for all installations involving submarine/underground reactor installations. For the compensation of the existing 115kV line, additional property will be required adjacent to the existing right-of-way. Significant land acquisitions would be required both in the Anchorage area and on the Kenai Peninsula to accommodate Battery Energy Storage (BES) systems. Summary estimate sheets for all reactive compensation scenarios are provided at the end of this section. Detailed estimates and associated general arrangements are provided in Appendix D. The following tables summarize the reactive compensation estimates by base route. One alternative estimate to the Quartz Creek route is also included as the underground Bird Point Crossing requires additional compensation beyond the base route. No other routes require additional compensation due to routing alternatives.

HLY 55-0198 (06/96) FINAL 120293-01/ab a SHUNT CAPACITOR BANKS The cost estimates are inclusive of utilizing shunt connected capacitor banks in 20 MVAR blocks. These are primarily for improving steady-state system operating conditions. As determined in the Systems Studies, the shunt banks must be augmented by a fast-acting device (Static Var Compenstors [SVC] or Thyristor Controlled Series Capacitors [TCSC]) on the existing 115kV Intertie. Accordingly, estimates for the shunt banks are included with either an SVC or TCSC. A general arrangement showing 2-20 MVAR. banks with a 0-20 MVAR SVC is shown on Figure RC-01 and detailed in Table RC-01 in Appendix D. The configuration with the 0-40 MVAR TCSC is provided with a single 20 MVAR Shunt Capacitor Bank. Refer to Figure RC-02 and Table RC-02 in Appendix D. SHUNT REACTORS The cost estimates for the shunt reactor installations are provided for both 138kV and 230kV scenarios. In general, the reactors are placed at the terminus of the submarine/underground cables. The following table summarizes the required shunt reactor installations.

HLY 55-0198 (06/96) FINAL 120293-01/ab 3 STATIC VAR COMPENSATORS The cost estimate provided for the SVC is included with the shunt connected Capacitor Bank, Figure RC-01 and Table RC-02 in Appendix D. The SVC operation for dynamic control is augmented by the more economical 20 MVAR shunt banks for the steady-state support. As described in the Systems Studies and Design Section Reports, the SVC provides dynamic stability during system disturbances. Significant control issues would have to be addressed to coordinate with the-existing SVC installations. SERIES CAPACITOR BANKS The cost estimate provided for the Series Bank is included with a 20 MVAR shunt connected Capacitor Bank, Figure RC-02 and Table RC-02 in Appendix D. As with the SVC, a portion of the var support is more economically provided by standard shunt banks. Normally (mechanically) switched series capacitors can not be utilized for the Southern Intertie application due to response time and Subsynchronous Resonance considerations. A more detailed description and discussion is provided in the System Studies Report. Accordingly, this estimate included a TCSC Bank. This device provides sub-cycle response time and mitigates SSR concerns typically associated with series compensation. TCSC provides the best overall technical solution considering both steady-state and dynamic system requirements. BATTERY ENERGY STORAGE BES has the unique capability of providing full power circle operation. More detailed operational information is provided in the System Studies and Design Section Reports. Estimates for two systems (Anchorage and Kenai) project were provided by vendors. Together the BES systems estimates varied between $41 million and $51 million. These are rough budgetary numbers only. Significantly more study work would be required to refine the BES capacity specifications which could significantly influence the capital cost. Accordingly, detailed cost estimates are not available for this option. HLY 55-0198 (06/96) FINAL 120293-01/ab 4 SUMMARY The following tables provide a cost estimate summary for each reactive compensation installation or applicable combination of installations for the Southern Intertie. Additional supporting detail can be found in Appendix D.

This estimate is based on previous EISs successfully completed by Dames & Moore with similar issues. Initially, we estimated the cost based on estimated miles of alternatives. The three primary routes (Tesoro, Enstar, and Quartz Creek) equal approximately 275 miles total. There are approximately an additional 145 miles of local alternatives within the three primary routes. Accordingly, a total of approximately 420 miles of alternatives are to be evaluated in the EIS. For major EISs in rural areas, costs typically average approximately $4,500 to $5,000 per mile of alternative. Using this average per mile cost, we estimated the overall costs to be approximately $1.9 to $2.1 million. In addition, the Southern Intertie Project has a number of significant issues that will require additional studies or effort. These are: e Urban Anchorage: Typical urban studies vary in cost from $250,000 to $750,000. Because the Municipality of Anchorage has prepared a plan for utilities, we do not anticipate maximum costs for this study. Estimated additional cost is between $250,000 to $300,000. e The National Environmental Policy Act (NEPA) requires all alternatives to be evaluated equally. However, the level of data currently existing for the potential alternatives is inconsistent. For example, the Forest Service’s data are the most complete and are at the level of detail desired for a transmission line project EIS. For the remainder of the study area, data gaps exist for soils, vegetation, visual concerns, etc. An additional $150,000 to $200,000 is anticipated for data collection. e Typically, after completing the initial feasibility or alternative identification studies, a solution for most utility projects becomes obvious. However, for the Southern Intertie Project, a combined least-impact and least-cost preference has not yet appeared because of agency issues and submarine crossing conditions. This will result in a difficult decision process with numerous decision meetings with the client, agencies and interested parties, graphics, and data management. Estimated additional cost ranges between $100,000 and $150,000. HLY 55-0198 (06/96) FINAL 120293-01/ab 1 The difficulties or agencies with significant issues are as follows: - State Parks - Forest Service - US. Fish and Wildlife Service - Corps of Engineers (404 permits) - Native Corporation Lands and Private Lands (Soldotna and Kenai areas) e The primary concerns include visual, wilderness, recreation/tourism, and wildlife habitat. The concern of federal and state agencies is the management of these resources and the potential impact of the transmission line on them. Since there is no clear resolution of these issues for the primary routes, we will need to conduct major mitigation studies in locally sensitive areas. Visual analysis will include numerous simulations and visibility analyses. Typical wilderness studies will include user identification and areas of potential impact prior to making mitigation recommendations. The level of analysis for recreation and tourism will be generally confined to mitigation of visual and physical impacts, while wildlife habitat may be somewhat more complex. The cost for additional visual and recreation/tourism analyses is estimated to be $100,000 to $150,000. The following table summarizes the overall environmental cost estimates. Environmental Cost Summary ———= Anticipated Cost ($) Potential Cost ($) Urban ane 250,000 300,000 $2,500,000 $2,900,000 " Estimated costs do not include client, legal counsel, or agency involvement (cost reimbursement). HLY 55-0198 (06/96) FINAL 120293-01/ab 2 Additionally, pre-construction surveys, monitoring during construction, and compliance planning are needed’. Their cost is estimated as follows: Additional Environmental Cost by Type The work in preparing the EIS is detailed in the following sections. ENVIRONMENTAL IMPACT STATEMENT The general technical approach, including the environmental studies and preparation of the EIS, is described below. It is important to note that we are assuming an EIS will be required, although there is always the potential to complete an environmental assessment (EA). Typically, this kind of work can be organized into seven main groups of activities, as shown below. Terminology may vary depending upon the lead agency. 1) Work Scope 2) Scoping 3) Inventory 4) Impact Assessment and Mitigation Planning 5) Preferred Route(s) Selection 6) Draft EIS (DEIS) 7) Final EIS (FEIS) A geographic information system (GIS) will be used to assist in the environmental analysis. This system will provide the ability to summarize the voluminous environmental data, assist reviewers and decision makers in identifying and assessing specific impacts, and compare routing alternatives. GIS applications will include: e Digitizing of resource inventory data as collected and recorded on maps by resource principal investigators e Conversion of mapped resource data to a digital database format > These estimated costs are not based on a final route and will need to be reviewed during the EIS phase. > Cultural and biological surveys may be required during the EIS phase. HLY 55-0198 (06/96) FINAL 120293-01/ab 3 e Development of impact assessment models to evaluate how construction and operation of the proposed project would affect resource values and features e Data report and presentation graphics, inventory and impact maps at various sizes and scales WORK SCOPE The environmental consultant would assist in the identification of a federal lead agency, including preparation of documents (e.g. preliminary right-of-way application, etc.), and initial agency meetings. The project’s preparation plan required at the initiation of an EIS will contain the overall scope of work, including management structure and responsibilities, technical approach for the environmental studies, methods for conducting the resource studies, and schedule. This preparation plan will be approved by the agencies. A public involvement program would also be developed and is expected to include the agency interdisciplinary team, newsletters, public open houses, working groups, and perhaps a project information line. In addition, the environmental consultant will assist the lead federal agency in preparing the Federal Register notice. SCOPING Several agency and public scoping meetings would be conducted. Prior to initiating the environmental process, the project team will meet with other federal agencies, which have the potential to become cooperating agencies for the EIS, to inform them of the project, discuss their issues and concerns, and invite their participation in the project. Follow-up meetings with the agencies will be conducted during scoping and throughout the project. The lead federal agency will execute interagency agreements with the cooperating agencies. The lead federal agency would prepare a Notice of Intent to prepare the EIS for publication in the Federal Register and establish the dates and locations for the public scoping meetings. Public scoping meetings would be conducted at various locations within the study area. The purpose of the meetings is to introduce and describe the project, explain the purpose of and need for the project, describe the environmental studies and public planning to be conducted as part of the environmental process, and solicit comments. The lead federal agency would conduct all scoping meetings. CEA, or its representative (e.g. engineering consultant), will participate by presenting the project description and purpose and need. The environmental consultant will present status of initial studies and will prepare displays, including project map and flip chart visual aids, handouts, and sign-in sheets. The environmental consultant will document and summarize the proceedings and prepare a report on the scoping process and results. Potential changes to the scope of work will be documented. A project mailing list would be established and maintained throughout the project. The environmental consultant would prepare fact sheets to send to all addresses on the mailing list HLY 55-0198 (06/96) FINAL 120293-01/ab 4 and would prepare news releases for all media within and nearby the study area, including newspapers and radio and television stations. A plan of development describing what can be expected for construction, operation, and maintenance will likely need to be prepared early on, depending on the lead agency’s requirements. INVENTORY Specific to the alternative corridors, available resource data previously not obtained through secondary sources (i.e., existing maps, databases, published and unpublished reports) and agency contacts will be researched and secured. The collection of data will be systematic and well documented. The environmental consultant will provide the resource study team with corridor base maps and a data documentation packet of standard forms to record the data sources. For example, information about the original scale and sources of data, assumptions used during collection, formats, dates, and additional sources will be part of the data documentation. Important to this procedure is the documentation of variations in data resolution and accuracies in order to understand any limitations of the data. These procedures will provide a means to ensure the applicability of the data and the validity of their sources. Preliminary base data initially will be developed for each alternative corridor based on refinement of the secondary data, supplemented by aerial photo interpretation and additional map studies. Environmental data will then be reviewed in the field, verified, and mapped in final form supported by graphs and tables as appropriate. The environmental resources to be addressed, at a minimum, include: Air Resources Earth Resources Water Resources Biological Resources Land Use Visual Resources Socioeconomics Electrical Effects Cultural Resources (prehistory, history, Native American concerns) It is important to note that the inventory study area or corridor widths will vary by resource depending on the needs and concerns for each resource study. For example, visual resources may be affected up to two miles from an assumed centerline, while effects to earth and water resources may be evaluated approximately one-half mile from the assumed centerline. HLY 55-0198 (06/96) FINAL 120293-01/ab 5 Once plots have been completed for each resource study, the resource study teams will input and verify data at an appropriate scale. A refined database for corridor level assessment will be constructed. Corridor base maps created on GIS/Computer-Aided Drafting and Design (CADD) will include roads and other features that allow registration. The environmental consultant will digitize all maps, provide check plots to scale, complete all editing changes, correct maps and cut into grid cells. Each corridor may be subdivided at an appropriate size and, when complete, will serve as the maps for digitizing. Each resource study team will be responsible for checking the accuracy and edge matching of data sets within the corridors. As necessary, corridor information will be produced on an overall map or separately. Technical reports will be produced and given to the lead and cooperating agencies as documentation for the EIS. Presentation maps will be prepared at the appropriate scale. IMPACT ASSESSMENT AND MITIGATION PLANNING The objective of the impact assessment and mitigation planning process ([A/MPP) is to conduct an interdisciplinary analysis of the potential environmental impacts and plan effective mitigation within the alternative corridors. Concurrent with the refinement of the environmental database, we will implement the IA/MPP. The methodology will be reviewed by the ID team, which includes the project participants, so that pertinent issues and concerns are addressed. The ID team will meet at key times during this task to understand the methodology and results. Potential environmental consequences (impacts) are based on the environmental effects that would result from the construction and operation of the transmission line along the alternative routes. Through the use of the IA/MPP, the potential direct, indirect, and cumulative impacts, the interrelationships (cause and effect) of impacts (beneficial, adverse, direct, indirect, local, or regional) will be determined. Determining impact significance is probably the most important and difficult part of impact assessment and will be determined through a systematic process of defining criteria for “thresholds” beyond which impacts are considered significant. Criteria for thresholds will take into account the magnitude, incidence, intensity, duration, and interrelationships of impacts and regulations. The criteria will be developed based on data collected, issues and concerns expressed, and relevant agency policy. Requirements for access involves where and to what extent roads would have to be built or upgraded to construct the proposed project facilities for each alternative corridor. The environmental consultant will assist POWER in determining where existing roads are sufficient or would require upgrading, and where new access roads would have to be constructed. Potential vegetation clearing will also be estimated. Specific impacts of each resource will be documented in the technical reports. The technical reports will be accompanied by data tables that indicate the location and description of specific resource features and values, initial impact levels of these resources, mitigation measures recommended to reduce impacts, and residual impacts expected following mitigation. The technical reports will be reviewed and approved by the ID team. HLY 55-0198 (06/96) FINAL 120293-01/ab 6 PREFERRED ROUTE(S) SELECTION Ranking the alternatives and selecting the “environmentally preferred” alternative or alternatives (or corridor) are the final steps before the preparation of the EIS. Ranking and comparing the alternatives are important in understanding the relative impacts of each. A multi-objective decision-making process will be used to evaluate and compare the environmental considerations inherent to the study area. Each resource study team (e.g. land use, biological, etc.) will conduct comparisons or rankings of the alternative corridors. These comparisons will be used to synthesize “cross discipline” rankings of all alternative corridors. The purpose of rankings is to develop an environmental ordering of all corridors under consideration. This comparison of corridors uses information and judgments rendered within each resource study. These data are organized around goals, of which the most important for the EIS is the identification of the environmentally preferred alternative or alternatives. All corridors will be ranked in order of environmental preference. Routing preference will be based on review of generalized impact levels, significant unavoidable adverse impacts, and other pertinent descriptive and impact data. Agency and public comments received through the public contact and information program also will be considered. The lead agency and cooperating agencies will identify the agency-preferred alternative or alternatives for inclusion in the EIS. Critical information from the project proponent is typically considered by the lead agency in its decision. DRAFT EIS (DEIS) The format of the DEIS will be in accordance with the Council on Environmental Quality regulations 40 CFR 1502.10 for preparation of an EIS. A preliminary DEIS will be prepared for review and approval by the lead and cooperating agencies. The schedule for preparing the preliminary DEIS will be carefully synchronized with the schedule of the environmental studies in order to ensure its timely completion and submission. For example, the chapter on the affected environment will be written after the resources inventory material has been developed. The chapter on environmental consequences will be completed after the impact analysis has been determined. Other special sections and appendices will be compiled throughout the preparation of the preliminary DEIS. The preliminary DEIS will be reviewed by the lead agency, CEA, and cooperating agencies. Review comments will be returned for incorporation by the environmental consultant into the final DEIS. Review meetings will be scheduled to clarify all comments on the report. The environmental consultant will then finalize the DEIS for final approval by the lead agency and CEA. HLY 55-0198 (06/96) FINAL 120293-01/ab q/ The environmental consultant will revise the report, if needed, and submit the final camera-ready DEIS to the lead agency. The lead agency will file the DEIS with the EPA, prepare and issue the Federal Register Notice of Availability, and distribute copies of the DEIS to interested parties. During the DEIS review period, the lead agency, with assistance from the environmental consultant, will conduct public hearings to receive comments. on the adequacy of the DEIS, make arrangements for the hearings, prepare notices and media releases, and conduct the proceedings. The representatives of the environmental consultant project team will attend the public hearings and provide input as needed. Preparation of the environmental presentation materials by the environmental consultant will be closely coordinated with the preparation of technical and engineering information by POWER. : FINAL EIS (FEIS) Following the public review period, the comments received will be reviewed by the lead agency, cooperating agencies, CEA, and the environmental consultant. The responsibility for developing appropriate responses for inclusion in the FEIS will be assigned by the lead agency. Presumably, the environmental consultant will prepare responses to all comments on the environmental studies while those related to the purpose of and need for the project, system planning, and engineering design will be completed by CEA. Following the development of the responses, the comments and their corresponding responses will be incorporated into the preliminary FEIS and submitted to the lead agency, cooperating agencies and CEA for review. Based on the comments from the review, the environmental consultant will prepare the FEIS for final approval by the lead agency. The lead agency will file the FEIS with the EPA and prepare and issue the Federal Register Notice of Availability. The environmental consultant will also prepare and issue media releases and newsletters, and distribute the FEIS to interested parties. At the close of the FEIS review period, the lead agency will prepare and issued the Record of Decision. A plan amendment may be required by a land managing agency, such as the Forest Service or Bureau of Land Management. Plan amendments are typically required when a preferred route does not utilize an existing or planned utility corridor documented in the Forest Plan or Resource Management Plan (Bureau of Land Management). PRE-CONSTRUCTION / MONITORING Prior to construction and potentially before agency approval on the selected alternative, a number of compliance studies are required. These include Section 106 (cultural) and Section 107 (biology). In addition, a Construction, Operation and Maintenance (COM) Plan would be prepared. The final element of environmental studies includes preparation of EAs (if needed) as well as other permits (e.g. Section 404). HLY 55-0198 (06/96) FINAL 120293-01/ab 8 RIGHT-OF-WAY AND PERMIT ACQUISITION INTRODUCTION In order to secure a right-of-way along an approved route, significant permitting and acquisition of private easements will be required. Because of the complexity of local, state, and federal agency permits, as well as the need to resolve concerns of private landowners, the right-of-way acquisition process will require close coordination among project team groups, i.e., CEA personnel, project management, environmental consultant , design staff, and the right-of-way personnel. Therefore, costs for right-of-way acquisition do not accrue only to right-of-way personnel. For detailed information about the project land status and anticipated permitting process refer to the Draft Lands/Regulatory Section Report. Cost information presented here was derived from researching the land status and property values along the core route for each of the three primary study corridors and their local alternatives. While the permitting requirements may not vary for a route selected anywhere within the boundaries of a study corridor, the number of private parcels may vary from one side of the corridor to the other, thereby affecting the cost of easement acquisition. PERMITS The three primary study alternatives, as well as their local alternatives, have many common permit requirements. Costs presented for permitting include title services, appraisals, and the assembly of exhibits and submission of the permit applications. Also included are costs to track the permit through the approval and granting process. Costs for conducting the appropriate environmental compliance associated with permits are covered in the costs for the EIS and pre-construction monitoring. Anticipated permit applications required include: Kenai Peninsula Borough Right-of-Way Permit Alaska Department of Fish and Game Title 16 Stream Crossing Permit Alaska Department of Fish and Game Title 16 Waterways Permit Alaska Department of Natural Resources Right-of-Way Permit Alaska Division of Governmental Coordination Coastal Zone Consistency Permit Bureau of Land Management Grant of Right-of-Way Alaska Department of Natural Resources Tidelands Lease Municipality of Anchorage Right-of-Way Easement HLY 55-0198 (06/96) FINAL 120293-01/ab 1 e State of Alaska (DNR), Division of Parks and Outdoor Recreation Right-of-Way Permit Corps of Engineers 404 and Section 10 Permit State of Alaska, Mental Health Trust Lands Permit Alaska Department of Transportation and Public Facilities Utility Permit U.S. Forest Service Special Use Permit Alaska Railroad Corporation Crossing and/or Easement Permit Kenai River Special Management Area Permit Alaska Department of Natural Resources Tidelands Right-of-Way Permit U.S. Fish and Wildlife Service RIGHT-OF-WAY ACQUISITION Land Field Services of Anchorage researched public records to determine estimates of parcels crossed by the various routes. Those sources were also used to gain a planning- level estimate of land values that could be used to derive easement costs. These data sources included: e Municipality of Anchorage Assessor and Recorder records for plats and assessed value; e Motznik Title Service for urban area land values; e Kenai Peninsula Land Management Officer, Assessor; and GIS Manager for maps, plats, parcel and cost information; and e Land Field Services, via past CEA project work, with an extensive in-house data base for lands crossed by the Quartz Creek 115kV Line. An individual parcel-by-parcel examination of location and cost relative to each specific route link was beyond this phase’s work scope and, accordingly, was not conducted. In- depth title searches and appraisals would be conducted for each parcel affected by the ultimately selected route within which right-of-way acquisition would occur. In some cases, particularly in the Anchorage area, the nature of readily available parcel information is such that parcel counts may be incomplete. Again, after a route selection process is complete, this would require an in-depth title search to provide the level of detail necessary to proceed with easement and permit acquisition. The records examinations described above reveal parcel counts for the core, or primary routes as follows: e Tesoro Route - 105 parcels between Point Woronzof and Bernice Lake; e Enstar Route - 58 parcels between the International Substation and the Soldotna Substation; e Quartz Creek Route - 93 parcels between University Substation and Soldotna Substation HLY 55-0198 (06/96) FINAL 120293-01/ab 2 In our analysis, it has been assumed for the links that parallel an existing road, highway, railroad, or other identified public utility corridor, the transmission line would be sited within the existing utility corridor. The rationale for this assumption is based on constraints of the Alaska eminent domain statutes. Those proceedings do not allow a utility to condemn private lands if a public utility corridor is available for the proposed use. Therefore, in those cases, right-of-way acquisition costs would accrue to permitting only, with no costs required for acquiring private lands. An examination of land status in the vicinity of landfall alternatives for submarine cable shows that nearly all are owned or administered by federal or state agencies. Therefore, the costs for reactive compensation stations site acquisition is covered within the appropriate permitting process. If an alternative landfall is chosen in the Klatt Road area, it is likely that private property would have to acquired for the landfall facilities. It is estimated that land values in that area are $152,000 per acre. Costs for acquiring this site are included in the costs for this alternative. As it may become desirable to expand the University Substation, an examination of land status to the east of the substation was made. A suitably sized parcel is privately owned in that area. Land values in this vicinity are currently approaching $200,000 per acre. Approximate land values in other project areas are as follows: Soldotna, $10,000/acre Point Possession, $20,000/acre north of Captain Cook State Park, $3,000/acre south of Captain Cook State Park, $5,000/acre tural lands along the Quartz Creek Route, $1,000/acre These costs form the basis for the direct cost of purchasing the easement. In the case of CEA’s easement payment policy, the landowner would receive 100% of the fee value of his property for the area encumbered by the easement. Costs for acquiring private rights-of-way include: title services appraisal services ($750/parcel) easement surveys and descriptions ($600/parcel) document preparation negotiation recording file transfer/close-out HLY 55-0198 (06/96) FINAL 120293-01/ab 3 The above listed costs form the basis for determining the indirect cost of right-of-way acquisition. Essentially, these costs are associated with the labor and expense of acquiring the easements. It is estimated that the total indirect cost per parcel for acquiring easements on this project would be $3,350.

Box 1066 Hailey, Idaho 83333 Attn: Mr. Jack Hand Re: Submarine Cable Circuit Turnagain Arm - Cook Inlet, Alaska Dear Jack, We have completed our rough estimate of installation costs for (4) single conductor 138kV oil filled submarine cables at (4) crossings in Turnagain Arm - Cook Inlet Alaska. We believe it would be in the customers best interest to embed these cables under the sea bed for the total length of the crossing. The embedment of the cables is based upon a jetting method utilizing high pressure water being applied to a cable burial machine. The cable is laid through the sled anc is placed at a pre-determined depth via a “stinger” located on the burial machine. It is also recommended that double armor be applied to the outer sheath of the cable for added protection and longer life. The armor should be the same lay for ease of handling. We have broken our estimate into two categories including j just laying the cables on the sea bed and laying and burial of the cables. We appreciate the opportunity to work with you and should you have any questions please do not hesitate to contact us. Best regards, Pirelli Ja€obson, Inc.

REGARDING YOUR FAX DATED JANUARY 9, 1996 Dear Mr, Aabo, In order to respond to your fax in dus time, I will submit 3 rough estimate of a similar cable with a alight difference in the cross section (750 MCM instead of 1000 MCM). The cable that we propose will be SCFF (self contained fiuid filled) cable as per attached cable technical dats with double armor. ee / . : The cable will have a polypropylene yarn serving and it will be manufactur¥d ih a continuous length. The budgetary price for the cable ex-factory Naples (Italy) is $160 USD / ft. To the above cost, you will hare to add the import duties and the transportation cost. Please also note that we have proposed a double armor cable because as you mentioned in some areas there -_ is rocky hard bottom and the cable burial is questionable from s technical and economical point of view. We have to inform you that our company owns different burial machines that use the jetting method but all are usable in sandy/omd bottoms, Le, jettable bottorn, and we do not have available machine for trenching in rocky bottom. Should you require an estimate for construction, please keep in mind the above. 5355 28th Avenue N.W.°** Seattle, WA 98107"*"°U.S A. Received: 01/09/96 07:37:24 From: 206 789 2851 a jee@5-1996 “gig?
