THE PROJECT The purpose of the Unalaska Geothermal Independent Cost Estimate Project is to provide the Alaska Power Authority (the Power Authority) with a comparison of engineering concepts and costs associated with the potential development of a geothermal resource on Unalaska Island. The resource is a water-dominated geothermal reservoir of 382° F discovered at a depth of 1,950 feet at the base of Mount Makushin, approximately 14 miles west of the Unalaska/Dutch Harbor fishing community. During the summer of 1986, the Power Authority secured the services of Dames and Moore and two subcontractors to develop: (1) a feasibility analysis, (2) a conceptual design, and (3) a detailed cost estimate for the Unalaska Geothermal Project. The resulting report, titled the “Unalaska Geothermal Feasibility Study,” will be the basis for the comparisons that will result from this project. The primary concerns of the Power Authority, as stated in the RFP and echoed in conversations with the agency's staff, are a thoughtful review and estimating of all costs associated with the project--for both the generating plant and the transmission LL 192IND 808753-15 (08/07/87) 1-1 e zoe) line--and a consideration of the conceptual design of the overhead portion of the transmission line. Additionally, the @ Power Authority has expressed an interest in alternatives that could result in significant cost savings within any portion of the project “without adversely affecting the integrity of the system,” according to the RFP. Other project considerations include the apparent lack of design data upon which the Dames and Moore cost estimate was based. For example, there is reportedly a detailed material take-off for the facility in Volume II of the report. However, the design drawings and related work required to prepare a detailed take-off are not presented. As can be seen from the conceptual P&ID in Volume |, not even the line and valve sizes are shown. POWER will prepare design data adequate to support the cost estimate we will prepare. @ 192IND 808753-15 (08/07/87) 1-2 @ Dove) \ 192IND BO8753-15 (08/07/87) ll. PROJECT APPROACH INTRODUCTION POWER has divided the Unalaska Project into a series of discrete components. Each of these components is required to have a complete system, and each represents areas with widely divergent technical expertise requirements. These specific component areas are as follows: @ Geothermal Power Plant ® Transmission Line @ Substations @ SCADA and Communications @ Environmental Impacts and Permitting (Including Offsite Access Roads and Structures) POWER will assign engineers with specialized experience in each area to: (1) do a general design review, (2) perform sufficient conceptual design work to provide an adequate basis for the cost estimate, and (3) prepare a capital and operating and maintenance (O&M) cost estimate. The results developed by the various design groups will be assembled into a draft report and submitted to the Power Authority for review. Upon receipt of the Power Authority comments, a final report will be issued. Y e2oier ) QOS PETIT L 192IND 8D8753-15 (08/07/87) Coordination of the various groups and tasks will be performed by the Project Manager. The POWER team has sufficient staff and a wide enough technical base to allow each of the project areas to be addressed concurrently. This means that a quality report will be prepared within the limited amount of time available to perform the work. The project deliverable, the report, will provide a description of the design review work, the documents and basis for the cost estimate, and the cost estimate itself. Concerning the estimate, the American Association of Cost Engineers has defined the following five levels of cost estimates: (1) Order of Magnitude Estimate (Ratio Estimate) - Rule-of- thumb method based on cost data for similar types of plant; probable error is 10 to 50 percent. (2) Study Estimate (Factored Estimate) - Better than Order of Magnitude; requires knowledge of major items of equipment and is commonly used for feasibility studies; probable error up to 30 percent. (3) Preliminary Estimate (Budget Authorization Estimate) - Requires more detailed information than Study Estimate; probable error up to 20 percent. (4) Definitive Estimate (Project Control Estimate) - Based on considerable data prior to completion of all drawings and specifications; probable error within 10 percent. (5) Detailed Estimate (Firm or Contractor's Estimate) - Requires completed drawings, specifications, and site surveys; probable error within five percent. Ne eDouel ) Coreen Porat eee The cost estimate POWER will prepare will be a eS} Study/Preliminary Estimate hybrid, and thus will have a probable error between 20 and 30 percent. The assumption as to the accuracy of the estimate is based on the quantity and type of data that will be prepared for input per the Association of Cost Engineers’ definitions. However, based on the depth of POWER’s experience with geothermal systems and transmission lines, we anticipate that the accuracy of our estimate to be better than 20 to 30 percent. GEOTHERMAL POWER PLANT This discussion addresses the activities POWER plans to perform to accomplish the design review and cost estimate activities for the geothermal power plant. Following an examination of the resource data and Dames and 6 Moore plant design, flash calculations based on fluid enthalpy will be done to confirm the steam and liquid flows to the power plant. A conceptual Piping and Instrumentation Diagram (P&ID), with major control loops shown and the valves and piping sized, will be prepared. An equipment list showing the name, quantity, material of construction, design conditions, and size or horsepower rating of each of the major equipment components will be prepared next. The following is an example of a typical entry in a mechanical equipment list: Name: Wellhead Separators Quantity: Two Type: Vertical, Bottom Steam Out Cyclone Separator Design Conditions: 250 psi, 450°F Material: 2 1/4 Cr, 1 Mo r Size: 36” ID, 15° 4" S-S Weight: 11,000 # 192IND 8D8753-15 (08/07/87) l-3 CLUE ‘Oagress roopoees (— | For the items on the mechanical equipment list, price quotations will be solicited from vendors. These quotations, along with freight costs for truck or rail transport to Seattle and barge to Unalaska Island, will form the mechanical equipment costs. A site plan drawing illustrating the plant, wellpads, and gathering and injection system pipe routes will be prepared to assist in preparation of the material take-offs. Major systems and components of piping, concrete, structural steel, valves, etc., will have take-offs done. Quantities for small systems and subsystems will be found by factoring. Material unit costs will be determined by soliciting quotations from suppliers and from standard estimating references such as the Richardson Rapid Estimating System and corrected as necessary to account for transportation costs. Labor hours will be factored based on equipment and material quantities using standard estimating references. The hours will be checked by referring to similar jobs. A composite labor rate and per diem costs will be developed for the project and applied to the labor time to arrive at labor costs. Certain line item plant costs such as engineering and procurement, spare parts, fee, construction management, and contingency will be calculated as a percentage of the total plant cost. All land and right-of-way costs, owners’ costs, well drilling, and well field development costs are assumed to be supplied by the Power Authority. Re 192IND B08753-15 (08/07/87) ll bas 4 CDM OY The most significant portion of the O&M costs is the personnel @ component. To determine this, POWER will first develop the operating, maintenance, and support/management staffing requirements based on the assumption of partially unattended operation. The salary requirements and payroll burden for these personnel will be based on the wage scale for the existing diesel power plant personnel adjusted for level of expertise. An annual maintenance shutdown requiring additional maintenance staff will be assumed. Costs to bring in and use contract maintenance personnel will be developed and included in the total personnel costs. Maintenance parts will be factored as a percentage of maintenance labor. Plant supplies will be estimated based on previous jobs. Transportation costs to the plant will be calculated based on the type of transport, distance, and number of trips per year. @ The above costs will be summed to develop the total plant O&M costs. O&M costs for the roads, docks, and transmission line will be developed in their respective areas. TRANSMISSION LINE The following are POWER’s objectives for our analysis of the transmission line: @ A thorough analysis of data prior to and throughout the Unalaska Geothermal Feasibility Study. @ Adetermination of the adequacy of the transmission design criteria used in the Feasibility Study. @ Recommendations for favorable design alternatives, if any. @ The preparation of detailed cost estimates for the preferred ° alternatives listed in the Feasibility Study. 192IND 808753-15 (08/07'87) -5 CLM Ores PooDoeee a 192IND 8D8753-15 (08/07/87) @ The preparation of detailed cost estimates for any favorable design alternatives proposed by POWER. @ A compilation of the above with recommendations assembled into a comprehensive final report. POWER’s review and analysis of the transmission system will include a field trip to Unalaska/Dutch Harbor and to the plant site. We plan to video tape and photograph the power plant site, access roads and proposed transmission line route. The information gathered during the review of existing data and the field visit will be compiled and analyzed. If, during the course of POWER’s investigations, an alternative route appears to be most cost effective and/or pose less environmental concerns than the preferred route referred in the existing study, then POWER will provide a description of the alternative route (with a map) with the rationale for the alternative. If, during the analysis of the line, conductor, structure and station designs presented in the existing study, POWER determines that a more cost effective design of the conductor, cables, and structure configurations could be utilized, we will provide a detailed cost estimate of the recommended changes. POWER will prepare a detailed cost estimate of the preferred alternative described in the existing study. POWER’s detailed transmission cost estimates will be in table form with explanations of estimates, methods, assumptions, etc. The estimates will be prepared on a real, 4th quarter 1986 cost basis. The estimates will depict quantities and unit prices. Mobilization and demobilization will be broken out as a separate item. POWER will also provide a breakdown of labor hours and costs, equipment costs, material cost, and indirect costs. "re @ Dales _) Sper rare a a aaa SUBSTATIONS e POWER will review the existing feasibility study to determine the adequacy of the station designs considering project design criteria as defined in the existing study. POWER will analyze the cost effectiveness and operability of the stations considering the reliability required because of the remoteness of the substation and switch stations. Major equipment identified in the feasibility study will be evaluated for the functionability and operating life expectance. Detailed cost estimates will be prepared for the proposed station configurations and design as defined in the feasibility study. If the design criteria change and/or other alternative designs appear to be more reliable than those presented in the feasibility study, POWER will cost out the alternatives. SCADA and COMMUNICATIONS POWER will review the proposed SCADA and communications systems for both the geothermal plant and substation(s). The SCADA monitor, control point count, and equipment selection will be reviewed for adequacy. The communications review includes SCADA and voice communication requirements, communications termination points and a cost breakdown of equipment including the carrier, such as wire, coax, fiber optics or microwaves. Recommendations for SCADA and Communication system alternatives and/or cost savings will be presented in the review, if applicable. 192INO 8D8753-15 (08/07/87) = 192IND 8D8753-15 (08/07/87) ENVIRONMENTAL IMPACTS AND PERMITTING Under the overall project direction of POWER, Hart Crowser personnel based in Anchorage will review the planned access road routing, dock siting, environmental studies, and permitting. This review will entail a cursory investigation of preliminary design parameters and developing cost estimates. Of special concern will be the assumptions used as a basis for assessing access impacts, and the costs associated with project environmental and permitting tasks. The Dames and Moore study determined the costs associated with environmental and permitting work to be “not significant”. Hart Crowser feels that the Power Authority should be appraised of realistic cost estimates for environmental and permitting services. 1-8 @ Dower) NX 192IND BD8753-15 (08/0787) lll. PROJECT MANAGEMENT INTRODUCTION POWER’s Project Management System is structured to ensure our projects are completed on schedule and within budget for satisfied owners. This system has been a key element responsible for POWER’s reputation and growth. CONCERNS Project overruns and schedule slippages are the problems most commonly encountered in the industry today. Problems related to inaccurate project definition, scheduling, or budgeting are generally the cause of project overruns and schedule slippages. These are interdependent concerns and will be faced by most owners, to one degree or another, on nearly every project undertaken. Additionally, the risks inherent in conducting a successful project are compounded by the complexity, schedule and participation levels required. The answer to successful project management of complex and simple projects alike lies in reducing projects to manageable divisions that are independently defined, scheduled, budgeted, tracked, and managed. Wh- 4 e2ue eS OWNER PARTICIPATION POWER encourages owners to actively participate in project management as an integral part of each project management team. In recognition of the value of active owner participation, POWER provides owners with the elements of our interactive Project Management System that incorporates Project Work Plans, Schedules, and Budgets in a cross-referenced system developed in-house specifically for the management of utility and industrial engineering projects. The primary purpose of the system is to provide accurate information quickly and easily, enabling project owners, managers, and engineers to make informed, accurate decisions without unnecessary delays. MANAGEMENT OBJECTIVES The four fundamental project management processes necessary for successful project initiation and completion are: @ Complete and accurate definition of the Work Plan. @ Generation of a realistic and definitive Schedule. ®@ Development of a comprehensive and accurate Budget. @ Execution and follow-through of the Project Plan. Together, the project Work Plan, Schedule, and Budget constitute the Project Plan. Ne 192IND BOD8753-15 (08/07/87) Il-2 eC DUe DR Pore PROJECT PLAN Once POWER’s project team has been defined, responsible individuals and departments generate their respective parts of the Project Plan by implementing the steps of our Project Management System outlined below. WORK PLAN For the Unalaska Geothermal Independent Cost Estimate Project, the Project Work Plan is comprised of the Task Outline and Task Descriptions. @ The Task Outline is developed to serve as a quick reference for all project participants. ® Project specific Task Descriptions are developed to serve as a definition of all activities or events that must take place or be accomplished in order to complete a specific task. @ All activities required to provide for a complete process are shown for clarity and completeness, irrespective of whether or not a specific individual or entity has been identified as responsible for such activities. PROJECT SCHEDULE @ Preparation of a Project Schedule is critical for describing overall project dimensions to both management and the project team personnel. Schedule preparation takes place coincidentally with Work Plan preparation. ® @ As the project proceeds, standard Schedule maintenance procedures are employed as project Status Reports are issued. 192IND 8D8753-15 (08/07/87) IIl-3 CLUE (Eee PTEOBE r — This process ensures the Project Schedule reflects the actual project status at any given time. PROJECT BUDGET @ Subsequent to the development and review of Task Descriptions and Project Schedule, man-hour and expense budgets are generated. ®@ Budgets are prepared using the Task Description Worksheets, in the Project Control Document, and man-hours and expenses are entered for each Task. @ A Summary Report is generated combining labor and expenses. Using this system, adjustments to the budget due to schedule or work scope changes can be easily accommodated. A new budget can be generated whenever required. This feature allows POWER to respond quickly to the Owner's needs. STATUS REPORTS Project Status Reports are generated weekly, monthly, and quarterly to assess budgeted and actual project progress. These reports provide management with the following information: e Budget -Allocated for the current reporting period. -Allocated to date. -Total allocated. -Average labor cost per hour budgeted.

TASK IDENTIFICATION POWER’s Project Management System uniquely defines, schedules, budgets, and describes each work segment by an identification number that allows management to monitor completion status. These numbers then cross-reference the schedule and budget. Wl-5 eZee Copan remo eee THE PROJECT MANAGEMENT SYSTEM Once the Project Plan has been reviewed and approved, it is entered in the Project Management System. Other inputs to the system are: @ Time Cards-Weekly @ Expense Vouchers-Weekly @ Material Costs-Monthly @ Equipment Costs-Monthly @ Percent Completion Reports-Monthly @ Change Orders-As Required All inputs are coded and charged against specific Task numbers. Preparation of the Project Status and Exception Reports is an automatic function of the System. Once the Schedule and Budget parameters have been defined for each Task, and following approval by management, the system produces Exception Reports as a part of the Status Reports. These Exception Reports identify Tasks that approach or exceed preset parameters. PROJECT MANAGEMENT PROCESS The pictogram on the following page graphically depicts POWER’s Project Management System and the interactive relationships of the system’s components. The process is effectively designed to handle even large scale projects with multiple Segments and/or multiple Service requirements (Siting, Studies, Design, Construction Management, Procurement, etc.). \ 192INO 808753-15 (08:07 87) ll-6 @ Due ) Spree Pea PROJE C T INITIATION © OWNER - POWER Mi TIME CARD S & EXPENSE CHITS PROPOSAL REVIEW & REVISION POWER ENGINEERS, INC.

SCHEDULE INTRODUCTION The following Project Schedule is a time-phased representation of POWER’s Work Plan for the Unalaska Geothermal Independent Cost Estimate Project. POWER personnel understand that scheduling is a vital part of project planning. Project manpower and cashflow requirements are developed in conjunction with the detailed Task Descriptions shown in the previous section. The result is a realistic and accurate schedule that provides the structure to manage all projects smoothly. The Tasks listed at left on the schedule are task headings. Numerical coding ties the Tasks to our Project Management System. The Project Manager will review the work progress and expenditures at the start of each week and compare them to the budget and schedule. Corrections, such as redirection of effort or relocation of manpower, will be taken as needed to remedy deficiencies or deviations from plan. al 192808753-15 (08/07/87) SCHEDULE COMMENTS The Schedule for this project is very tight. However, as POWER has the expertise in-house for the major components of the project, the geothermal power plant, the communications system, and the transmission and distribution system, coordination of Project activities and communication between personnel will be easily accomplished. In addition, because POWER has worked with Hart Crowser on a number of projects, our firms have developed a strong working relationship that enhances project performance. The most significant factor that could jeopardize the project Schedule is one that we will have no control over during this project--this factor is the weather. Should inclement weather delay the site visit by POWER’s engineer, then we will be set back in beginning the tasks to follow. Similarly, if weather causes an extended layover in the Dutch Harbor area, the Schedule will also be impacted.

BUDGET INTRODUCTION This section contains a summary of the overall project cost for the performance of the Tasks described in detail in the “Work Plans” section of this proposal. ¢$ As stated in the cover letter, POWER will perform the Tasks described in the Work Plan section of this proposal for a fixed price not to exceed $25,000. Even though this is a short-term, fixed-price contract, POWER has implemented its normal budgeting procedure for the Project. Based on the Work Plan, the manpower requirements, computer time, and other expenses were estimated for each task. These estimates then form the budget for their respective tasks. Through the course of the project, the costs expended will be tracked on the Task level. Internal reports detailing the previous week’s expenditures on a task-by-task basis are prepared at the first of each week and submitted to the Project Manager. This allows the Project Manager to stay current with @ the status of the project so that corrections can be made as a 192 IND BD875315 (08/07/87) Vi-1 ezue S 192 IND BD875315 (08/07/87) needed to maintain the Budget and Schedule. This is especially important on a short-term project as an inappropriate application of manpower or resources over even a two-week period can cause significant deviations from the Project Plan. POWER’S BUDGETING PROCESS The Budget included in this section is a product of POWER’s integrated Project Management System. Like the Work Plan and Schedule, it is subject to the Power Authority's review and approval. POWER’s project team personnel use a computer-generated budgeting input form to enter projected labor hours and expenses for each Task. Task descriptions from the Work Plan and the Project Schedule are used as guidelines for estimating manpower requirements and any expense costs. Labor for each Task is estimated in man-hours for each of POWER’s eight job classifications. These man-hour estimates are then entered into the computer where labor costs are calculated through the application of POWER’s current fee schedule. POWER’s standard expense costs include air fares, per diem, car rentals, reproduction, communication, field office costs, lease vehicles, computer costs, and other miscellaneous costs. These costs are entered into the computer in unit formats, such as number of trips, days, hours, etc. a e Dole) XN 192 IND BD875315 (08/07/87) BUDGET SUMMARY The following sheets itemize POWER’s Task costs for the Unalaska Geothermal Independent Cost Estimate Project. For the Task to be performed by Hart Crowser--Environmental, Permitting, Access Roads and Docks--the cost is a line item adjacent to the subcontractor category. Therefore, the Hart Crowser work is shown simply as an expense to the Project.

The APA and these other utilities are investigating the possibility of constructing a new intertie or upgrading the existing one. The APA contracted POWER to conduct a feasibility study for this purpose. The utility's . concern is whether the potential increase in CLIENT'S NEED capacity and reliability is worth the cost associated with engineering, permitting, right- of-way acquisition, construction, and operating and maintaining the facilities over its useful life. Alaska Power Authority (APA) Conduct a feasibility study needed to determine the desirability of constructing a new intertie and/or upgrading the existing intertie between Anchorage. ahd tie ena Parasia APA has specified five aspects for POWER to address: (1) determine the need for a new PROJECT SERVICES transmission line between Anchorage and the Kenai Peninsula and determine a complete field of options if such a line is needed; (2) assess upgrading the existing Chugach Electric Association and Homer Electric Association lines; (3) conduct a transmission route selection study for a new transmission line; (4) determine envionmental and permitting requirements for recommended routes; and, (5) prepare a cost estimate for the recommended new line and or upgrade of the existing line. @ Route Study @ Field Surveys @ Land Ownership Analysis @ Study Area Mapping @ Cost Estimating @ Transmission System Studies @ Reconnaissance Studies @ Environmental Assessment ISSUES & CONCERNS After existing studies of the utility have been reviewed, POWER conducted its own transmission system studies using an in-house system specifically designed for scientific and engineering applications. The POWER System Analysis (PSA) programs are run on @ Avalanche and Wind Damage @ Submarine Cable Placement @ System Stability @ System Reliability @ System Capacity @ Schedule Constraints BS Environmental Ganciraint? POWER’s network of Apollo supermini computers. These programs included Load Flow Studies to evaluate the existing and proposed PROJECT DESCRIPTION transmission system and a Stability Study to analyze the voltage and phase conditions during and immediately following a system disturbance. The results of these studies were analyzed to determine the optimum voltage level, conductor size, line configuration, switching requirements, and reactive compensation requirements for the proposed intertie. A 115kV transmission intertie between Anchorage and the Kenai Peninsula experiences extended outages because of avalanche and wind damage in the winter. Although the generation capacity on the peninsula is able to meet the peak load during these outages, connected railbelt utilities wish to maintain a reliable and stable transmission system because the existing transmission system is weakly interconnected with widely dispersed POWER also researched the land use and environmental issues concerned with this NX CDE ) OO PFA project and developed cost estimates for land services and geographic conditions for right of way acquisitions, permits, engineering, material construction management, submarine cable construction, and maintenance costs for each alternative route. POWER selected a preferred route among four possible routes: the existing line, upgraded to 230kV and three other proposed routes. POWER also determined the design criteria for the transmission system. Because the Cook Inlet must be crossed to reach the Peninsula from Anchorage, an added feature which POWER will address in these steps will be the design and routing for submarine cabling . POWER conducted this study in conjunction with Hart-Crowser, which provides environmental, land, and geotechnical services and has extensive Alaskan and arctic experience.

Prior to the preparation of proposal POWER is performing conceptual design and evaluation of generation and transmission options to supply power to the USAF. PROJECT SERVICES Conceptual Design Process Flow Diagrams Equipment Selection Cost Estimates Reliability Analysis Economic Analysis Proposal Preparation ISSUES AND CONCERNS ' Economic Feasibility t System Reliability t Cost of Service PROJECT DESCRIPTION The USAF is seeking to purchase very reliable power with an estimated total demand at the transmitter site of 10 MW (5 MW demand at each transmitter sector). A maximum unscheduled electrical service outage time of 1/2 hour per year will be allowed (99.9943% availability factor). More specifically, the maximum allowable electrical service interruptions are two (2) 30 cycle outages per year or one (1) 15 minute outage of electrical service to either transmitter sector. POWER’s approach for assisting CVEA in preparing a proposal to the USAF for the OTH- B Radar Project is broken into two phases. PHASE I POWER, after reviewing the existing data pertinent to the Project, is performing a study of potential service scenarios. The service scenarios include a “do-nothing” service scenario that is used as a base case to compare the other scenarios against. POWER is investigating viable generation alternatives within each service scenario and is developing a preferred generation alternative for each scenario. Options being studied include construction of a 138kV transmission line to the site and additionally providing either (1) on-site generation for back-up generation or (2) expanding the existing power plant at Glenallen. Generation options under evaluation include internal-combustion engine-generator sets, combustion turbine- generator sets, expansion of hydroelectric capacity, and construction of a coal-fired power plant. In addition, the possible incorporation of a large scale Uninterruptible Power Supply into the system to provide the required reliability is being evaluated. PHASE II Phase II will consist of preparing a formal Proposal to the USAF based upon the results obtained in Phase I.

ENGINEERING SERVICES System Design System Start-Up Operator Training Materials Specifications Operator Manual Preparation Maintenance Manual Preparation PROJECT DESCRIPTION POWER’s Alaskan project experience includes the design and supervision of the installation of generator switchgear in the Pribilof Islands. The switchgear automatically controls a generation facility providing power through eight diesel generators ranging in size from 175 KW to 350 KW. Since the demand for power on the islands varied during the day, more generators than necessary were kept online to prevent power failures. The switchgear provided voltage, frequency stability, and load sharing. POWER insured that the switchgear was installed in less than three hours, as the client had specified. POWER designed the load-shedding system to keep on-line only the power needed to serve immediate system loads. To meet the varied daily demand, the generators are now automatically started and stopped. POWER’s design included a predetermined selection to cycle the different generators on and off so that all generators are used periodically. If a partial power failure occurs, the load is shed to prevent complete power failure. If complete failure does occur, the load is isolated, one generator is started for station power, and an alarm is automatically sent to the operator by telephone. To ensure total success of this new system, POWER handled all equipment selection and procurement responsibilities, conducted the Start-up procedures, trained the operators, and prepared operating and maintenance manuals.

Comparison of Upgrading Existing Systems Versus Installing New System PROJECT DESCRIPTION POWER personnel performed power plant heat rejection study for the coal-fired Chena Station located in Fairbanks. A key consideration in the Chena Station plant modernization and expansion plans was development of a suitable method of heat rejection from condensing steam turbine units. The existing plant used Chena River water in a once-through cooling system. The warm water from the power plant resulted in thermal degradation of the river and winter ice fog problems. The potential for increasing the severity of these problems precluded the expansion of the once-through system. Alternatives investigated included using a once-through system and discharging the heated water to the Fairbanks city water system or through an existing sewer system utilidor to the Tanana River as well as using dry or wet/dry condensers. Also for this project, several power generation options were considered as methods of increasing the output and improving the reliability of the plant. POWER personne! also performed an economic analysis to determine which of the options was most economically attractive.

The Beluga 230kV Station will provide voltage transformation, metering, line protection and switching for existing and future 230kV transmission from the gas-fired generating plant to expanding load centers 40 miles away in the Anchorage area. The project is being designed and constructed in two phases. Phase | consisted of the design of a three- breaker ring bus scheme to provide protection and switching for an existing 138-230kV, 300-MVA autotransformer, a 230kV line and a 138kV line to be con- verted to 230kV. Phase II design involves the addition of a second 230kV, 300-MVA autotransformer bay and three more circuit breakers to convert the station to a breaker-and-a-half scheme. Design provision is also being made for addition of a future 230kV line terminal. 7) x N 7-9 ar both Bd bate She ttn a cof la ot? Severe space constraints in the heavily forested project area dictated siting of the 380’ x 270’ station addition on an active streambed. This constraint, as well as the Station’s location in the subarctic zone in a Zone 4 seismic area, required that extensive geotechnical investigation be conducted and elaborate site prepara- tion be performed during Phase |, including stripping of the overburden and use of non-frost-susceptible fill material. In addition, two 60” x 46” flat-bottomed galvanized steel culverts were specified to channel the stream under the north end of the yard and a French CLUE EAFes PDT drain system was designed to lower the water table. A 10-foot step was incorporated in the station grade to minimize the amount of fill required. 8, 9 VERTICAL REBARS AT 1°-3 0/C F 04 TIES, TYPE B, AT 12°O/C #4 TIES, TYPE AAT 12°0/C DATUM 100.0" (SEE NOTE 3)] ‘SUBGRADE 09 veRTICAL = REBARS AT 1°-3 0/C-—F Sees Sees =a 2-4" RIGIO INSULATION LAYERS 04 TIES, TYE A 6 8. aes plae ge EXTENDED 4-0 PAST EDGE OF FNO BASE.

Shallow-bottomed spread footings were designed to avoid high water-table problems, while buried styrofoam insulating board was specified to prevent frost penetration. To protect the nearby stream from accidental oil contamination, POWER designed a sophisticated oil spill containment system which features concrete-walled catch basins with impermeable membrane liners and imbiber bead drains around all oil containing equipment. Koa Electrical design for Phase | of the Beluga 230kV Station was complex. It involved extensive relaying and control interface with existing station facilities to provide integrated protection coordination. The state-of-the-art protection scheme designed by POWER utilizes dif- ferential and sudden pressure protective relaying for the transformer and bus, breaker failure relaying for each circuit breaker, and distance relaying for the lines. Design interface was also required for the station’s new microwave-operated SCADA system. POWER was responsible for placement of the remote terminal unit in the control house and schematic wiring. Other electrical design tasks included a contro! house annunciator with both local and remote alarms. Structurally, the new station is designed to withstand Zone 4 seismic loads and features tubular steel station structures designed for both strength and aesthetics. Over 300,000 Ibs. of steel were required for the sturdy yet architecturally streamlined structures. Additional POWER responsibilities on the estimated $6.1 million project include design of the line reroutes necessary for proper station-line interface, survey supervision and limited contract administration and construction monitoring services.

The new dual-transformer, 25-MVA station supplies power to all refinery facilities via six underground feeders, with design provision for two additional feeders. Its main-with-bypass bus scheme allows for isolation of the power circuit breakers for maintenance, or total station bypass if required. Design of the facility, located in Alaska’s subarctic zone, presented several engineering challenges. The most significant of these involved site preparation. Sited out of necessity on an old riverbed with a shallow water table, the station would have been extremely susceptible to frost heaving during the frigid Alaskan winters. To eliminate this potentially serious problem, POWER civil engineering personnel specified excavation of the entire substation site, placement of a special fabric lining under foundations, and backfill with non-frost-susceptible fill material. In addition, special spread-footing foundations with frost barriers were designed to neutralize the site’s teegereesggunscgee high water table and severe winter freezing problems. Due to its proximity to the existing river, the new facility also required an oil spill containment pit around each of the transformers. The subarctic climate imposed other special design considerations. Winter temperatures in the -40°F to -70°F range required specification of two oil heaters per transformer, extra equipment insulation and placement of the 13.8kV metal-clad switchgear inside the station’s super-insulated control building. Interface with other plant electrical systems provided additional engineering challenges. Special relaying arrangements were designed to protect the station and utility supply against reverse power flow from in-plant generation, while two capacitor banks were specified to control VAR-induced voltage fluctuations on the feeders caused by the plant generation. Complex design interface was also required with the local utility’s SCADA system and the main plant Foxboro Spec- trum Coordinated Control System. POWER coordinated its design effort closely with the local utility, MAPCO and the other electrical contractors on the project to ensure proper systems interface. Additional POWER responsibilities with regard to the main plant substation included design of the 69kV transmission source loop, material procurement, construction inspection, and testing and ener- gization. Designed and constructed on a fast-track schedule, the modern facility was energized on time.

A proposed new direct connec- tion to the Tracy Station would provide more power, allow substantial savings, and also provide greater system reliability. The participants contracted POWER Engineers to identify transmission line corridor alternatives with the highest probability of providing acceptable locations for the project. POWER also conducted preliminary electrical system analyses. For each identified route alternative, POWER provided cost estimates for comprehensive environmen- tal studies, engineering and design services, right-of-way acquisition, and construction services. In addition, POWER also identified activities necessary to complete the Tracy Station-Bay Area Transmission Line and developed two project schedules. During this study, POWER consulted many city, county, and private agencies to determine which areas within the overall study area would be most in conflict and which would be most compatible to the proposed project. As a result of these consultations, several areas of special environmental concern to be avoided were identified. FUTURE 4a ae SANTA CLARA Based on the findings from this study, POWER recom- mended routes that shared existing linear utilities and right-of-ways. POWER concluded that a number of reasonable alternatives existed and that further com- prehensive and detailed environmental and engineering studies should be conducted. ( SUMMARY POWER's clients needed a focused direction in which to further pursue a complex transmission line project. POWER identified the major stumbling blocks to be avoided and a general workable route that significantly contributed to the project progression.

The completion of this project brought new service to the remote areas of Cape Chiniak and Narrow Cape on Kodiak island, as well as provided more reliable service to existing customers. In conjunction with the preliminary and final design of the 44-mile “back bone” line, POWER designed the single- and three-phase taps, three-phase step-up transformer bank, two three-phase underground segments, and both overhead and underground secondaries and services. CLUE Exes POOR (| Design Features for a Rugged Environment. Kodiak Island’s remoteness and severe climate presented interesting challenges for POWER’s design team. High winds and winter icing conditions in the project area required NESC “Heavy” loading criteria to be applied to structure design. POWER designed the distribution line to use predominantly single-pole wood structures with 4/0 and 1/0 ACSR conductors. For the extremely rugged areas, however, POWER determined that the sturdier H-frame structures would be more appropriate. Because of a history of vandalism in the area, POWER recommended polymer insulators. Environmental Concerns. Several design features were based on environmental factors. To design the REA structures for raptor safety, POWER lowered the crossarm on a standard REA base structure to increase conductor separation. The line also followed a raised causeway bordering a salmon migration route. Because the causeway did not provide adequate easement for the structures, POWER designed a special pole-peninsula foundation in the water. These peninsulas were designed to minimize the impact along this environmentally sensitive area. Radio Interference. Aware of the United States Coast Guard’s concerns of radio frequency interference, ~ POWER designed the segment of line at the Holiday Beach site to maintain the required one-mile distance from the Guard’s communication facilities. Construction Management at a Remote Site. POWER’s construction management team performed bidder prequalification, including specifications to ensure that the contractor had recent experience with remote locations and possessed adequate Alaska licenses and bonding. Although managing a construction job at a distant site presents added difficulties, POWER successfully handled the extra challenges. POWER allowed extra lead time to procure and ship materials to Kodiak Island; when unexpected right-of-way constraints required a redesign of 25 percent of the structures throughout the line, design and orders for new structures and equipment were handled expeditiously. Rugged Terrain and Construction Techniques. Because of the severe, rugged terrain in certain portions of the route, the contractor framed the structures in yards and transported the structures via helicopter to the structure site. At that time, specially equipped track vehicles set the structures. This method of construction minimized impact to the environment by reducing the need to cut in access roads.

No’ authorize design and construction of a distribution line to be fed from a new hydroelectric generation source on the island. The new facility was constructed for incorpora- tion into the Kodiak Electric Association system. Routed along the west side of Kizhuyak Bay, the line required several special design considerations. Recorded winds in excess of 138 mph and heavy icing conditions in the area required design to NESC “Heavy” loading criteria. Salt, sea spray and fog contamination required specification of extended leakage post insulators to reduce the increased flashover potential created by these conditions. To provide raptor protection for bald eagles and other birds of prey on the island, the crossarm on the delta-configured, standard Rural Electrification Administration VC1 structure used for the line was lowered to allow for additional conductor separation. Underground entry at the Port Lions distribution substation involved design of a 550-foot underground run ad ee VM3-25R utilizing directly buried 4/0 URD cable. Other special design features included specification of a three-phase oil circuit recloser for line protection and design of a recloser bypass structure at the Port Lions termination.

The line is needed to provide an outlet for projected joint-owner generation that will exceed existing Geysers area transmission outlet capacity. Line facilities will consist of 61 miles of 230kV 6 transmission line and 13.5 miles of 230kV collector line in the Geysers area. POWER Engineers has provided \ 2 GEOTHERMAL PUBLIC POWER LINE (GPPL) NORTHERN CALIFORNIA all preliminary engineering services required to license the project with the newly formed California Energy Commission (CEC). The first phase of the two-phase licensing process involved submission of a Notice of Intent (NOI) document that was designed to provide the CEC and other interested groups with general decision-making infor- mation regarding the project. Upon CEC review and approval of this document, phase two was initiated. This phase involved preparation and submission of the Application for Certification (AFC), a document that more precisely defines all project aspects. Certification for the project is contingent upon the CEC’s extensive review and final approval of this document. During the NOI phase of the $60 million-plus transmis- sion project, POWER performed a spectrum of preliminary engineering tasks necessary to identify the following: routing for each of the alternative corridors, voltage levels of proposed lines, tower types and configurations, ruling spans, conductor types and config- urations, code requirements, design criteria, operating criteria, construction methods and schedules, and corona and electrical field effects. In addition, an extensive economic analysis of alternatives and construction cost estimate and was prepared that included ruling span and conductor optimization studies. The vital NOI document CLUE Epees POTOBeS Lam cost tora: eT | MR rat ms: assisted the joint owners in selecting a preferred route and provided the CEC with an important body of economic information concerning the alternatives. For the AFC, POWER transmission design personnel conducted in-depth studies and calculations required to establish the design parameters to be utilized for final design of the line facilities. These included recom- mended tower types and configurations, mechanical- structural design criteria, conductor configuration, tower height requirements, phase spacings and other pertinent design aspects. In addition, preliminary structure spotting ( was performed during this stage to assist in establishing a definite route to be submitted in the AFC as the joint owners’ preferred route. Recommended design features of the 61-mile main transmission line include 57 miles of double-circuit, vertically configured steel lattice towers through the mountainous portion of the line and 4 miles of double- circuit, tubular steel poles leading into the new switching Station in the Sacramento Valley. Two-conductor bundled ACSR “Seahawk” was identified in POWER’s conductor optimization study as the best conductor application for the 1000-MW-capacity line. Due to high recorded winds and elevation in excess of 3000 feet, California “Heavy” loading was identified for portions of the line. The pro- posed GPPL's location in Zone 3 and 4 seismic areas required additional final design loading criteria to be recommended. POWER design personnel identified both single- and double-circuit, single- and bundled-conductor segments for the 13.5-mile steel tower collector line in the Geysers area, based on projected generation loads. The optimum conductor identified for this line was AAC “Marigold.” Recorded winds near 100 mph in the Geysers area will require application of a special high-wind loading con- dition to final design, along with additional seismic Zone 4 loading considerations. In addition to preliminary design of the transmission facilities for the GPPL, POWER also provided preliminary design and cost estimates for the various station alter- natives and conducted all land and environmental services associated with this phase of the project.

Originating at a tap of an existing 138kV circuit near the rural community of Grouse Creek, the line is routed in a southwesterly direction approximately 8 miles to feed Raft River’s new Grouse Creek 138-24.9kV Substation. From there the line runs south and then southwest through 24 miles of high- desert valley and rolling foothills to the new Tecoma 138kV Station, which houses another RREC 138-24.9kV substation and a 138kV switching station owned by Wells Rural Electric Company. CDallel_/ oS oe oe The Grouse Creek-Tecoma Line was designed and constructed on a very compressed schedule, both to upgrade an overtaxed, unreliable distribution circuit in this area of RREC’s service territory and as the first leg of a new 138kV power source for Wells Rural’s isolated West Wendover Substation, projected to be incapable of serving burgeoning power demand in the Wendover, Nevada, area by the summer of 1985. Funded by the Rural Electrification Administration, the line was designed to utilize standard REA transmission structures. However, design of a special transposition ELEVATION ———— LOOKING AMEAD ON LINE ll structure using a modified REA TH-15 configuration was required to satisfy Bonneville Power Administration wheeling requirements. In addition, high wind and winter icing conditions necessitated use of NESC “Heavy” loading criteria and side guying of structures in exposed wind spans.

The new line was designed to replace a rapidly deteriorating 24.9kV line constructed in 1952. Though originally conceived as a single 32-mile line, revised demand projections caused the line to be designed and constructed in three separate phases. The Sunbeam-Stanley 69kV Line represented the final phase of this project. Originating at the small community of Sunbeam on the scenic Salmon River in central Idaho, the wood single- pole and H-frame line runs westward for approximately 12 miles through the Salmon River Mountains adjacent the river to just outside the town of Stanley. There the 69kV overhead line ends and is converted to an 1800-foot, three-phase underground tie to existing @ distribution. \ Located in the Sawtooth National Recreational Area in extremely rugged terrain, the new line necessitated special routing and design considerations. Though primarily routed along the right-of-way of the existing line, a Forest Service requirement to minimize visual impacts dictated a major reroute around a campground. To further minimize environmental impacts, non-specular conduc- tor and forest-green guy guards were specified by POWER transmission design personnel, and structures spotted from ridge to ridge where possible. Due to high wind and severe winter conditions in the project area, NESC “Heavy” loading criteria were used for design of the wood structures utilized on the line. A specially designed, reinforced single-pole structure was C Dole TH-IR WITH VCIH U.B. employed for short ruling span sections of the line to accommodate the use of 336-kcmil ACSR transmission conductor and future 4/0 ACSR underbuild on the same structure. H-frame structures were used in longer ruling span sections of the line for canyon and river crossings and ridge-to-ridge spans. Besides complete design responsibility for the high- altitude line, POWER also conducted required system Studies, land services, survey and construction manage- ment through project closeout. The new facility was completed within budget and on schedule despite difficult access and terrain conditions that required considerable helicopter construction.

The Thompson Creek-Sunbeam Line was designed and constructed as the second phase of a three-phase project to accomplish this upgrade. Intended for future 69kV transmission with 24.9kV distribution underbuild to accommodate system expansion, the line was initially energized at 24.9kV and included design of numerous services and taps to customers along its 12-mile length. Routing of the line through the scenic Salmon River Gorge on primarily Forest Service land required several environmental and visual impact mitigation measures to be taken. Non-specular 336-kcmil conductor and forest- green guy guards were specified to reduce visual impacts, along with careful routing around campground facilities. Care was also taken to route the line behind natural cover wherever possible to minimize its visibility from the nearby state highway. Further impact mitigation CDallel measures included use of H-frame structures in mountainous terrain to allow for longer spans and ridge- to-ridge structure spotting. Other routing constraints were imposed by the narrow river gorge and extreme-terrain sections that necessitated several river crossings and helicopter-assisted construc- tion along portions of the line. The rugged terrain and severe winters required use of a specially designed, extra-sturdy single-pole structure to support the transmission and future underbuild conductors in the NESC “Heavy” loading area. The rein- forced delta-configured structure, modeled on the Rural Electrification Administration's TP-3 structure, features a heavier crossarm and additional pole hardware with higher strength ratings. =| lull [nee] |nle|s|ale|>|e|a [0] =|5|= ae ee eel ltl In addition to its design responsibilities, POWER also performed all required system studies, land services and construction management through energization and project closeout. For its close coordination with the Forest Service and careful adherence to Forest Service environ- mental strictures and requests during the design and construction of the transmission facility, POWER received a letter of commendation from that government agency upon timely completion of the project. PROJECT COMPLETION: August 1983 PROJECT COST: $991,000 CITY OF BOUNTIFUL 46KV TRANSMISSION LINE NORTHERN UTAH CLIENT City of Bountiful Light & Power CLIENT’S NEED Provide land, engineering design, and construction ser- vices for a 26-mile, 46kV transmission line, consisting of single-pole and H-frame wood structures, located be- tween two hydroelectric projects and Bountiful, Utah. The line passes through the Wasatch Mountain Range, re- quiring design and construction features for steep, rug- ged terrain that also minimized land and visual impacts.

POWER Engineers was contracted to pro- vide a full range of professional services for the 46kV line, which would start from Echo Dam with a tap to the East Canyon Dam and continue to a point on the east side of Bountiful. Each project phase (land services, design, and construc- tion management) could have been performed by separate firms. By using POWER’s multiple services, however, the client received the additional benefits of pro- ject continuity and consistency, with a minimum of lost time that results from redundant review of the same data. C2allel Landowner Contact Continuity. POWER’s land ser- vices team, conducting easement acquisition and per- mitting for right-of-ways, contacted approximately 50 private landowners of farms and ranches, as well as representatives of land owned by the Utah Department of Wildlife Resources, the Bureau of Land Management, and the Wasatch-Cache National Forest. Consequently, when the construction contractor, whom POWER manag- ed, began work for this project, POWER’s already established rapport with the landowners and agencies improved the progress for construction. Environmental Concerns Identified. When performing land services, POWER identified several environmental concerns voiced by the county, the Forest Service, and private landowners. These included visual impact con- cerns and concern about increased accessibility to previously remote areas. Consequently, POWER’s land services team’s deep understanding of the environmen- tal issues could be accurately communicated to POWER’s design and construction support teams. Design Features and Environment. POWER’s design staff effectively designed the line with a sensitivity for the line’s visual and environmental impact without com- promising system integrity. When ascending the scenic Wasatch Front, single-pole structures were used to minimize the visual effect. When the line went out of view into the steep valleys, however, longer spans were re- quired. H-frame structures were used to permit these longer spans. Throughout the route, POWER’s design minimized the amount of clearing that was needed through the aspen and scrub oak forests. During con- struction, to minimize impact on both private and public property, helicopter transport was used over large por- tions of the line. Routing Constraints Affecting Design. During the in- itial routing studies, POWER identified the client’s re- quirement that the route follow an existing pipeline as much as possible. Consequently, approximately half the route used the pipeline’s right-of-way. This requirement influenced structure location and required special con- sideration during the design process. Quick Response to Reroutes. During the project, a short unexpected reroute was necessary because of a landowner’s sudden change on a right-of-way decision. Fortunately, POWER’s land services and design teams could respond quickly to make the reroute and incor- porate it into the design; POWER’s construction manage- ment team, having immediate knowledge of the changes, could process the necessary change orders expeditiously. Other Design Features. POWER designed the 46kV line for 69kV because of the 9000-foot Wasatch Range eleva- tion. The line consisted of both single-pole and H-frame wood structures, using 266 ACSR “Partridge” conduc- tors and special NESC “Heavy” loading to accommodate the high winds and ice during the area’s winters. Light- weight, easy-to-handle polymer insulators were chosen because of their resistance to gunshot damage; this add- ed feature minimized the effects of potential vandalism. Rugged Terrain and Construction Techniques. The rugged Wasatch Mountains and limited access to the line’s right-of-way required special construction tech- niques. The contractor used off-the-road equipment and several different helicopters to move men and materials along the line. For the mountainous portion of the line, most structures were framed in assembly yards and flown to the structure site. Despite early snow and resulting mud, the construction was completed on time and with minimum impact on the autumn deer hunting in the area.

This project will tap into the existing Alaska Power Administration's Hydroelectric Plant intake tunnel to divert flow to the Eklutna Water Project distribution system, presently under construction. The project includes a 8,500-foot-long, 72-inch finished diameter tunnel. Hart Crowser accomplished geotechnical explorations and an extensive groundwater pump testing program, while coordinating a multi-disciplinary design team consisting of four Alaskan firms as well as outside @ tunneling experts. Geotechnical exploration for the tunnel utilized several different drilling and sampling techniques to accommodate boulders. Unanticipated groundwater conditions were discovered during the work, and required a timely, cost-effective change in exploration with little disruption to the design schedule. Hart Crowser developed the soil and groundwater data needed for design engineering for the tunnel as well as valve shafts, short pipeline and culvert sections, and 6,500 lineal feet of access road.

DPP Drilled Pier and Piling program for the calculation of the ultimate lateral resistance and lateral deflections at working loads of single piles and pile groups installed into saturated and unsaturated, cohesive and noncohesive soils. The ultimate lateral resistance is calculated assuming that failure takes place, e either when one of two plastic hinges form along each individual pile or when the lateral resistance of the supporting soil is exceeded along the total length of the laterally loaded pile. Lateral deflections at working loads are calculated using the concept of lateral subgrade reaction taking into account edge effects, both at the ground surface and at the bottom of each individual pile. This computer program was developed by mathematically modeling the results and findings presented in the Journal of the Soil Mechanics and Foundation Division, Proceeding of the American Society of Civil Engineers, by Bengt B.

LEE RANCH MINE NEW MEXICO Project Name: LEE RANCH MINE Brief Description: POWER prepared a feasibility study to determine the cost effectiveness of installing a 7.5 MW cogeneration unit at Santa Fe Coal Co.’s Lee Ranch Mine for Stan Burns and Associates. The project consisted of a conceptual design for the unit, a capital and operating and maintenance cost estimate, and an economic analysis. Scope of Estimating Effort: Basically this was a + 30 percent accuracy estimate suitable for preliminary feasibility analysis. POWER secured cost estimates for the major equipment components and factored the balance of the equipment and installation costs.

COST ESTIMATE All cost estimates included in this section are in first quarter, 1986 dollars. As these are budgetary estimates, the accuracy range of the capital and operating and maintenance cost estimates is + 25%. Although the costs are in present day dollars, it is assumed that by the time the decision was made to go ahead with the project, the engineering, construction and commissioning of the plant would take until the end of 1987 and the plant would go on-line at the start of 1988. Capital Cost The estimated capital cost for this 7.5 MW plant is $11,795,000. This is felt to be a reasonably accurate estimate, more so than would normally be anticipated with the estimating methodology used. This is due to the fact that this estimate compares very favorably with a recently completed plant using similar technology. Exclusions to the estimate are land costs, owner's costs for financing and administration and owner's costs for startup (operator training, home office technical assistance, etc.). To develop the estimate, vendor budgetary quotations were secured for the following equipment and systems: ° Turbine-Generator Set with Auxiliaries ° Fluidized Bed Combuster and Boiler with Fuel Handling, Ash Handling, Fans, Pollution Abatement, Duct and Related Steam Generation Systems (Installed Price) Cooling Tower (Erected) Circulating Water Pumps Deaerator Condensate Pumps Boiler Feedwater Pumps 2738K (7) Other mechanical equipment and systems costs were factored from similar plants using the sixth-tenths rule or were prepared using comparable estimating methods. These are as follows: Condenser Flash Tank Feedwater Preheater Make-up Treatment System for Boiler Feedwater Cooling Tower Water Treatment System Crane Firewater Pumps The steam generation train is an installed cost so it was set aside as a separate item along with the erected coolng tower (which did not include the basin) in the initial stages of the capital cost preparation. The total of the costs for the other equipment was then used as the basis to calculate the remaining costs for installation, support systems, etc. The installed equipment costs quoted by the suppliers were then summed with the calculated balance of plant costs to determine the total plant capital cost. The total capital cost was then spread over the various categories of direct and indirect costs which would make up the project to illustrate the anticipated cost breakdown. The results are shown in Table 1, Capital Costs. Operating and Maintenance Cost The annual operating and maintenance (O & M) cost summary in first quarter, 1986 dollars is given in Table 2, Power Plant Operating & Maintenance Cost Summary. The discussion which follows provides the background for each of the line items in the O & M summary. Labor Labor costs consists of 3 components, operating, maintenance and supervisory/administrative labor. For operations, the plant has 4 shifts which will operate the plant 24 hours per day, 7 days per week. Each shift will consist of one operator (the plant is designed to run with a minimal operating staff). An extra operator is included in the staff as a "floater" to cover vacations and sick leave. A salary of $40,000 per year, which includes fringe benefits, was used for the operators. For maintenance, it was assumed that two full time maintenance technicians are required to support the plant. Their salary, including fringes, was also figured at $40,000 per year. It was also assumed that a contract crew or maintenance people borrowed from the mine would be required for the 2 week annual shutdown. To derive this expense, it was assumed that a 4 man crew would work 10 hours per day for 14 days at $20 per hour per person. Supervision for the operating and maintenance staff will be provided by the plant engineer. This individual's salary was figured at $55,000 per year including fringes. Administrative duties, such as payroll, personnel, etc., were assumed to be handled by the mine at no charge to the power plant. 2738K (8) Table | e CAPITAL COSTS Cost lst Qtr., '86 Description ($ 1,000) Direct Costs Purchased Equipment $ 3,622 Purchased Equipment Installation 1,461 Instrumentation and Controls (Installed) 502 Piping (Installed) . 1,087 Electrical (Installed) 678 Buildings 360 Yard Improvements 117 Service Facilities 175 Land 0 Total Direct Costs $ 8,002 @ Indirect Costs Engineering and Supervision $ 1,169 Construction Expense 1,297 Contractor's Fee 351 Contingency @ 7.5% 876 Permitting 100 Total Indirect Costs $ 3,793 Total Costs $11,795 2738K (9) Table 2 POWER PLANT OPERATING & MAINTENANCE COST SUMMARY Ist Qtr., '86 _($1,000/ Yr.) Labor $ 346 Maintenance Parts 91 Fuel - Coal 722 Natural Gas 3 Limestone 59 Supplies : 30 Power 9 Total $1,260 Note: No costs were assumed for water supply to the plant, for waste water treatment, or for ash disposal. 2738K (10) Maintenance Parts For maintenance parts, 100% of maintenance labor costs were assumed. This includes both Santa Fe Coal and contract maintenance costs. Fuel To find annual coal costs, an operating time of 7446 hours, which is based on an 85% availability, was multiplied by the 6.46 ton per hour feed rate and $15 per ton coal cost. The natural gas is required to heat the bed for startups. A unit price of $3.50 per thousand standard cubic feet and 21 startups per year were assumed to arrive at the annual natural gas cost. Limestone Limestone, which is added to the fluidized bed to control sulfur dioxide, is dependent on the quantity of sulfur in the coal feed stream. From the ultimate analysis, the highest sulfur concentration was 0.87 weight percent, so the total sulfur was found using the annual coal feed which was previously calculated. A limestone addition rate three times that required by the reaction stoichiometry was used along with a $15 per ton cost to get the annual limestone expense. Supplies The supplies category covers costs for those miscellaneous things required for plant operation. This includes janitorial services at $1,500 per month, telephone at $100 per month, paper supplies, water treatment chemicals, etc. Power The power plant will consume some power when it is off-line. This power consumption rate will be quite low when the plant is completely down but will approach the full parasitic load when the fans and pumps are running such as will occur during startup. The total annual off-line time of 1314 hours was used along with a 100 kw per hour usage rate and $.067663 per kwh energy cost to calculate the power cost. Demand charges were ignored but the use of the highest on-peak energy rate should compensate for this simplification. 2738K (11) FILE C DUE TELEPHONE RECORD project ce 22 cc: PILE @ DOWEL TELEPHONE RECORD @ : ; Projecto z JobNo. ZY9¢g/ To > Phone No. U3 Lede - 4265 owe 2helen From 1 0 Time ——$$___ | =_ EAU TELEPHONE RECORD projet 20% Ze Lan Co. 2 LL mM WEL, La To A 4h or band Ge ae ) Soy) gap tied L . ~ [rs A \eCha. chm ; 8s Date 2/2. 55) 6G From AJ@w WMearyou Pe élic Servico COMNAE2.£ Subject Ljher 4 ; at Pal ne Por tear P— tees Leer under [Odie W% Sr ary?
