Tuluksak Yupiit School District ECM 22 Inspection Tuluksak 1992
_ALASKA ENERGY AUTHORITY Yupiit School District ECM #22 Inspection Tuluksak, Alaska June 22, 1992 TULUKSAK ECM #22 INSPECTION I. Background and Statement of Purpose A. Project History/Scope of Work The Yupiit School District received a grant through the Department of Community and Regional Affairs (DCRA), Grant Agreement DE-FG-06- 80R000892, Amendment A074, Amendment ECM 022, revised, to upgrade the diesel generators and waste heat system in the Tuluksak Elementary School, install an electrical intertie to the high school, and provide power to the City of Tuluksak. The Scope of Work included installing two new Cummins LTA10, 1200 rpm, 145 kw diesel gen-sets and associated waste heat recovery equipment at the elementary school, and an electrical intertie to both the high school and the City (Attachment I). The total fuel savings in ECM #22 was estimated at 34,125 gallons; 13,000 gallons saved from the waste heat system and 21,125 gallons saved by operating one efficient central power plant and shutting down the high school and the City power plants. Description of Copper Valley Construction Company (CVCC) project and comparison to original Scope of Work The project performed by Copper Valley Construction Company consisted of the following: 1. Repowering the existing two diesel gen-sets at the high school with Caterpillar 3304 1800 rpm diesel engines rated at 75 kw prime power. 2. Installing an electrical intertie from the high school to the elementary school complete with transformers and fused disconnects. 3. Installing a new main distribution panel and load balancing the elementary school. 4. Upgrading the waste heat recovery/cooling system at the high school power plant. The CVCC project did not include an intertie |! with the IRA Council's distribution system, and the Council still continues to operate its own power plant. The original Scope of Work for ECM #22 estimated that the high school and elementary school consumed only about 45% of the estimated combined electrical consumption for the high school, elementary school and City. Therefore, there is less waste heat available than originally estimated and a lower overall fuel savings realized. 1The School District and the IRA Council did not reach a power sales agreement prior to the project. 92Q2\D3140(1) Purpose of Inspection The purpose of the inspection was to determine the following: 1. Observe the operation of the school power plant, waste heat system, and electric intertie. 2. Review CVCC's plan and cost estimate for work performed, including as-built drawings and equipment installed. Determine if the project cost was reasonable and customary. 3: Prepare a final inspection report assessing the project. 4. Provide color photos of the project. Il. Scope of Work Topics A. 92Q2\JD3140(2) Inspection of the waste heat system and electrical intertie between the two schools Two 3304 PC Caterpillar Diesel engines were installed at the high school power plant on existing Kato 1800 rpm brushless generators. A 2400/4160 kv direct bury electrical interconnect was installed from the high school to the elementary school complete with step-up and step-down transformers and fused disconnects. At the time of the site visit on Monday, June 22, 1992, unit #2 was on-line carrying a load of about 20 kw, with 25 amps on all three phases. The elementary school was receiving its power from the high school power plant and the electrical interconnect appeared to be functioning properly. The waste heat system was providing heat to the high school. (The WH system needs to have more antifreeze added to the waste heat piping system and air vented from the piping). The diesel engines appear to have been installed in a professional manner using the appropriate materials for the job; however, it is our opinion that the installation of the step-up and step-down transformer banks for the electrical intertie at both the high school and elementary school does not conform with the intent of the 1990 Edition of the National Electric Safety Code (NESC) Tables 232-2 and 234-1. The transformers are located approximately nine feet above grade, Table 232-2 requires a minimum clearance from ground to unguarded rigid live parts (Section 1.d, 750V to 22kV) of 14 feet. During the winter months, the packed snow becomes the grounded surface on which operators or other individuals stand. Therefore, the transformers need to be elevated so that the minimum clearance to ground will be maintained during the winter months. Table 234-1 requires a minimum horizontal clearance from wires, conductor, cable, and unguarded rigid live parts adjacent but not attached to buildings...(Section 1.a(1)) of 5.0 feet. Both sets of transformer banks are located less than five feet from the nearest building wall. Therefore, the poles on which the transformer are mounted need to be relocated so that the transformers meet the minimum 5.0 foot clearance to the wall. Conclusions Finally, the electrical panel for the step-up transformer bank at the high school needs to be locked. Design Plan and Cost Estimate Prior to the Energy Authority's field visit to Tuluksak, CVCC provided us with a design plan for the project (Attachment II). As-built drawings were not provided after completion of the project. However, the design plans closely reflect the as-built status of the system. CVCC also provided a brief synopsis of their Scope of Work for the project (Attachment III). The Yupiit School District provided a property inventory list to the Energy Authority prior to the site visit. It appears that some items are not on the list and some of the items on the list may have been from different projects. CVCC did not provide an initial cost estimate for the project before the site inspection, but after the Energy Authority's field visit, they faxed us a labor and materials cost breakdown (Attachment IV). While CVCC's labor and Caterpillar engine costs are higher than we would estimate, it is also fair to say that we do not know how CVCC's profit and overhead are distributed in the cost breakdown. Prior to the field visit, CVCC had provided the Energy Authority with copies of invoices from Potelcom and Debenham Electric for costs associated with the electrical intertie. However, these invoices appeared to contain some items that may have been from other projects CVCC was working on at the time. Total Project Cost The estimated project cost for the original Scope of Work for ECM #22 was $122,175 (Attachment I). The overall cost of the work performed for this project was estimated at $125,500 by the Energy Authority staff (Attachment V). CVCC's total billing for ECM #22 is $123,375 (Attachment IV). 1. The project as performed by CVCC is not the same project as outlined in the Scope of Work for ECM #22. 2. Since the Council still generates its own power, less waste heat and fuel savings are realized than estimated for ECM #22. 3. An itemized inventory list for the major components of the project should be provided by CVCC to the Yupiit School District. 4. The work performed by CVCC on the generator repower and waste heat/cooling system generally appears to conform with good workmanship practices. 5. It is our opinion that the installation of the step-up and step-down transformer banks for the electrical intertie at both the high school and elementary school does not 92Q2\JD3140(3) conform with the intent of the 1990 Edition of the National Electric Safety Code (NESC) Tables 232-2 and 234-1. The transformers are located approximately nine feet above grade, Table 232-2 requires a minimum clearance from ground to unguarded rigid live parts (Section 1.d, 750V to 22kV) of 14 feet. During the winter months, the packed snow becomes the grounded surface on which operators or other individuals stand. Therefore, the transformers need to be elevated so that the minimum clearance to ground will be maintained during the winter months. Table 234-1 requires a minimum horizontal clearance from wires, conductor, cable, and unguarded rigid live parts adjacent but not attached to buildings...(Section 1.a(1)) of 5.0 feet. Both sets of transformer banks are located less than five feet from the nearest building wall. Therefore, the poles on which the transformer are mounted need to be relocated so that the transformers meet the minimum 5.0 foot clearance to the wall. Finally, the electrical panel for the step-up transformer bank at the high school needs to be locked. 92Q2UD3140(4) ATTACHMENT I Department of Community & Regional Affairs Grant Agreement DE-FG-06-80R000892, Amendment A074, Amendment ECM 022 92Q2\JD3140 APPENDIX A Grant Agreement DE-FG-06-80R000892, Amendment A074 Department of Community and Regional Affairs Division of Community Development Amendment ECM #22, Revised Concept TJ7758 (9) ALASKA POWER AUTHORITY Hi yg yy = ave) sha an 334 West Sth Avenue, (dE WEI “DU IRCAUIN SMI aA 2nd Floor Anchorage, Alaska 99501 Date [= NO (907) 276-0001 — 10/30/89 (907) 277-7641 Mr. Norm Bair RE Tuluksak elementary school TO Department of Community and - Regional Affai GENTLEMEN: WE ARE SENDING YOU OC Attached O Under separate cover via_________the following items: O Shop drawings O Prints O Plans O Samples O Specifications CG Copy of letter OG Change order Qo COPIES OATE NO.

ECM # 22 REVISED CONCEPT As the existing diesel generators in Tuluksak Elementary School are of a make and model known to be one of the most inefficient installed anywhere in Alaksa, is hereby proposed that ECM #22 be amended to the following scope: Install 2 ea. new "State of the Art" diesel generator sets with accessories and jacket water waste heat recapture equipment in Elementary School. Provide electrical connections to Tuluksak High School and to the community wide electrical distribution system and operate the generators in the Elementary School on a continous basis to provide all electrical needs in Tuluksak. (The local utility has agreed to this concept.) COST ESTIMATE: 2 ea. generator sets with accessories 82,000 Jacket water waste heat recapture equipment 14,000 Transmission line materials 9,000" Transportation 11,000 Installation labor (Alaska Energy Authority) 25,000 <j s Project cost $141,000 = Note: Design and installation methodology is assumed to follow Alaska Energy Authority standards. GENERATOR CONVERSION EFFICIENCY: The conversion efficiency of the proposed "state of the art" generators (Cummins LTA 10 modified for 1200 rpm _ continous operation) is based on actual testing of an identical Alaska Energy Authority owned unit in Renton, Wa. on 9/29/89 by Energy Authority personnel. Test results: @ 61.9 kw load: 34.8% or 9,807 Btu/kwh @ 103.4 kw load: 37.8% or 9,029 Btu/kwh @ 144.3 kw load: 38.7% or 8,819 Btu/kwh The loads in Tuluksak will almost consistently be above 61.9 kwh as an annual total consumption for all users including the schools has been estimated at 764,400 kwh/year. including losses. (High Tuluksak in Zz » oO ys ‘A pf $b z - ¢fa QO,” = NS School consumption has been estimated at 204,000 kwh/year while the remaining community has been estimated to consume 438,000 kwh/year.) A slight conversion efficiency reduction will be caused by fluctuating loads, a Power factor different from 1.0, the use #1 diesel fuel, and Parasitic loads for switch gear and control system operation. Consequently, an average conversion efficiency of 32.0% has been used in the following calculations. JACKET WATER WASTE HEAT AVAILABILITY/SAVINGS The above electric loads will Produce 2,087.1 MMBtu of recoverable waste heat on an annual basis with the Proposed diesel generators. It is conservatively estimated that the main boiler room, which is proposed connected to the waste heat recapture system, uses 13,000 of the estimated 18,000 - 21,000 gallons of fuel consumed for heating purposes in the Elementary School each year. At the estimated boiler conversion efficiency of 65% this corresponds to 13,000 x 0.65 x 134,000 = 1,132.3 MMBtu/year. Even with very limited seasonal variation in electrical consumption patterns, the entire 1,132.3 MMBtu/year needs would easily be satisfied by the waste heat recapture system. The Lower Kuskokwin Delta villages traditionally experience very significant annual electric load variations with low summer loads and high winter loads due to traditional activity patterns. As waste heat availability closely reflects generator loading, this will make more heat available during the winter months and less during the summer, thereby making it a very safe assumption that the entire heating load can be satisfied as shown. SAVINGS FROM IMPORVED GENERATION EFFICIENCY: Annual savings from improved generator efficiency for Elementary School electrical consumption only: Previous generation related consumption: (122,400 kwh x 3413 Btu/kwh)/0.101 4,136.2 MMBtu New generation related consumption: (122,400 kwh x 3413 Btu/kwh) /0.32 1,305.5 MMBtu Savings: (4,136.2 - 1,305.5) 2,830.7 MMBtu In gallons: 2,830.7 MMBtu/ 134,000 Btu/gallon = 21,125 gallons TOTAL SAVINGS: Total annual savings for proposed system: (21,125 + 13,000) gallons = 34,125 gallons Total annual cost savings for proposed system: 34,125 gallons x $0.898 $/gallon = $ 30,644 /year. Pay back time for project: 141,000/30, 644 = 4.6 years. Note: The above calculations pertain only to the Elementary School. The very significant fuel savings resulting from drastically improved fuel-to-electricity conversion efficiency improvements for High School and community loads have not been quantified and have not entered into the above calculations.

P.a2 RE: TULUKSAK HORK TO BE ACCOMPLISHED The Tuluksak High School was being served by two (2) 50 KW 3 phase John Deere powered generators, both of which were reading high time . The Elementary School was served by one (1) 50 KW single phase GM powered generator with no standby backup. There was no interconnection existing between the schools. After reviewing peak demand records for both schools, it was apparent that the average high peak demand reached 63 KW; therefore a 75 KW generator was determined adequate to supply both schools. A cost analysis of available options showed that up-sizing the High School generators and providing an inter- connect between schools would provide the most cost effective system within available funds. BRIEF SYNOPSIS OF THE WORK ACCOMPLISHED IS AS FOLLOWS: 1. The John Deere 70 horsepower engines which powered Kato generators at the High School were replaced with 115 HP Caterpillar $304’s providing 75 KW prime power with peaking capacity of 90 KW. 2. An underground inter-connect was installed, including transformers and fused disconnects. 3. Anew main distribution panel was installed at the elementary school which included load balancing and checking of wiring within the elementary school generator room. 4. The waste heat recovery system at the high school was cleaned and flushed with some parts being replaced to provide a functional and efficient operation. JIUN— S-s2 FRI 16 129 ; 7 P.los A Pra PESCRIRTION OF BAGH OPERATION IS. As FOLLOWS: 1._GENKERATOR REPOWER Caterpillar 3304 PC engines rated at 115 peak horsepower were installed on Kato 1800 RPM brushless generators. After an initial run-in period both plants were tested for up to four (4) hours at 90 KW demand. Both plants maintained RPM, and cycles, with no noticeable rise in generator temperature. In accordance with manufacturer specifications all systems were monitored and checked for torque at 250 and 500 hours. Both plants are functioning properly. 2. INTERCONNECT As shown on the One Line Diagram a direct-bury interconnect was installed between the high school and the elementary school. Included is a Pole Mount 15 KVA Transformer at each end with fused disconnects. The buried cable is 5 KY cu'l 624-B airport lighting cable. The cable route is marked with REA specification buried cable markers in accordance with REA specifications for underground cable marking. Materials purchased for the project are shown on the enclosed invoices from Poteleom and Debenham Supply. B.MAIN_ DISTRIBUTION PANEL : ELEMENTARY SCHOOL A new MDP was placed in the old elementary generator room to replace the existing load center. As part of that effort, éach eircuit was checked for maximum loading and the load was balanced to comply with NEC regulations. New breakers Were installed and tested. 4._WASTE HEAT RECOVERY SYSTEM. The existing waste heat recovery system in the high school was tested and found deficient in several areas including: a. Inadequate circulation ef glycol from the generator module to the school. b. Various sensor and control problems: 1. Fused wiring in main control panel JUN- S-92 FRI 16:180 : 2. Inoperative low water alarms. : 3. inoperative return water temperature sensor 4. Improperly adjusted valving 5. Inoperative thermostats. c. Water flow restricted by scale. d. Dirty radiators in overheat system. e. Worn pumps. All of the above problems were corrected by replacing inoperative parts or cleaning and adjusting the remaining pieces. 5. TOTAL SYSTEM The total system was tested and brought to a fully functional status.
