Include information about the number, size, age, efficiency, and type of generation. The Marathon hydroelectric project is located in Seward, Alaska. The project was constructed in the early 1980's as a combined water supply and hydroelectric project. The project consists of a small spring -fed diversion, approximately 3,500 ft. of 12"-14" steel penstock, and a small powerhouse housing one single jet pelton turbine, driving a 250 kw induction generator via a speed increasing gear. The project was designed by Ott Water Engineers to operate at 8.5 cfs under 440 ft net head. The powerhouse also contains pumping equipment to pump water from the tailrace into the City's water supply system. The project operated until sometime in the l 990's when an electrical problem caused the project to shut down. At the time of the equipment failure, the project was no longer part of the water supply system and revenues were not sufficient to justify repairs. The project has remained off- line since then. 4.2.2 Existing Energy Resources Used Briefly discuss your understanding of the existing energy resources. Include a brief discussion of any impact the project may have on existing energy infrastructure and resources. Currently, the City of Seward electrical utility grid purchases power from Chugach Electric.

The project was constructed in the early 1980's as a combined water supply and hydroelectric project. The project consists of a small spring -fed diversion, approximately 3,500 ft of 12"-14"steel penstock, and a small powerhouse housing one single jet pelton turbine, driving a 250 kW induction generator via a speed increasing gear. The project was designed by Ott Water Engineers to operate at 8.5 cfs under 440 ft net head, The powerhouse also contains pumping equipment to pump water from the tailrace into the City's water supply system. The project operated until sometime in the 1990's when an electrical problem caused the project to shut down. At the time of the equipment failure, the project was no longer part of the water supply system and revenues where not sufficient to justify repairs. The project has remained off- line since then. AVTEC has approached the City of Seward about using the project as a training facility for utility operators. HDR Alaska was contracted by the Alaska Energy Authority to assess the project and determine the feasibility of using the project as a training facility. As part of this work, HDR engineers visited the site May l 1-12, 2010 and inspected the project and interviewed personnel familiar with the project. This report provides a condition assessment of the facilities as they are now and provides recommendations and needed repairs to make the project operational again. A site visit report is attached as Appendix A. 2 Existing Project Works The project consists of the following major components. A general description of each follows. 2.1 intake The intake was not accessible at the time of the site visit, but the construction drawings were reviewed. The intake includes a small dam, intake screens, and a level sensor that is wired to the power plant. The condition of the signal wiring and the float operated sensor were not assessed but it is assumed they are no longer operational. AVTEC personnel report that the intake appears to be in relatively good condition and does not have sediment accumulation but does have accumulated leaves. 2.2 Penstock The penstock was not accessible at the time of the site visit but it is assumed to be operating condition. There have been no reported leaks or other problems with the penstock by those familiar with the project. Since the project has been shut down a small amount of water has been allowed to flow through the penstock to protect it from freezing. Alaska Energy Authority 1 July 30, 20I0 Marathon Hydroelectric Plant Condition Assessment 2.3 Shut-off Valve The penstock terminates with a gate valve equipped with a Limitorque electric operator. The valve is currently partially open and according to AVTEC personnel is not operable. A pressure gauge mounted upstream of the shutoff valve is scaled 0 -- 300 PSI. The gauge reading changes as the isolating valve is closed or opened indicating that the piezometer tap for the gauge is likely fouled. Figure 1. Turbine Shutoff Valve with Electric Operator 2.4 Turbine The turbine is a single jet impulse turbine of the Pelton design. The turbine does not have any nameplate or manufacturer's information on the case but, based on the speed increasing gear name plate, it appears to be designed to operate at approximately 730 rpm. The turbine is equipped with an electrically operated spear, with provision for manual operation by hand wheel. The electric operator was designed to be controlled automatically to regulate the intake pool elevation. At the time of the site visit, the operator had been removed from the spear mechanism. Its condition is unknown. It was noted that there is a small seeping leak in the weld that mounts the spear shaft packing box and guide bearing to the inlet case. This may indicate significant corrosion of that weld has occurred. Alaska Energy Authority 2 July 30, 2010 Marathon Hydroelectric Plant Condition Assessment Figure 2. Turbine, Speed Increaser and Generator The turbine has a deflector designed to prevent flow from hitting the runner during a shut -down sequence. The deflector is not designed to be partially operated. The deflector is weight operated and released by actuation of an electric solenoid. Resetting of the deflector requires hoisting of the weight using the overhead crane. The deflector was cycled several times and appears to be in working order. The turbine runner is mounted on a shaft with anti -friction bearings on each side of the turbine housing. At the time of the site visit the tailrace chamber was full of water and therefore the runner could not be inspected. 2.5 Speed Increasing Gearbox The turbine is coupled to the low speed shaft of a speed increasing gearbox. The speed increaser is rated 720 rpm/] 750 rpm. The gearbox is equipped with grease lubricated antifriction bearings on both shafts and with a motor pump for forced oil lubrication for the gears. The oil circulating system includes a water/oil heat exchanger which uses cooling water from the penstock. Alaska Energy Authority 3 July 30, 2010 Marathon Hydroelectric Plant Condition Assessment Figure 3. Speed Increaser with Cooling and Forced Oil Lubrication system 2.6 Generator Power is produced from an induction generator. The generator was manufactured by Reliance Kato Engineering and is rated 250 kW, 1773 rpm, 480 volts, 3 phase 60 Hz and includes internal thermal protection. The generator bearings are grease lubricated antifriction bearings. 2.7 Controls The turbine -generator controls are packaged in the top half of a single cabinet. The bottom half of the cabinet contains an electrically operated power switch, current transformers, and a power resistor bank. Alaska Energy Authority 4 July 30, 2010 Marathon Hydroelectric Plant Condition Assessment Figure 4. Control and Switching Electrical Panel The controls consist of conventional control switches, indicating lights, meters and protective relays mounted on the door, and a Texas Instruments programmable controller and a few control relays mounted in the interior back panel. The control panel encountered some amount of component failure which has apparently never been resolved and the panel assembly has been partly disassembled. The relay components have not been properly closed with the covers. Alaska Energy Authority 5 July 30, 2010 Marathon Hydroelectric Plant Condition Assessment Figure 5. Generator Main Switch inside Control Panel A main power disconnect for the generator power is mounted on the back wall of the building. A separate feeder disconnect provides service for the station power and lighting was energized at the time of the site visit. 2.8 Transformer The original design drawings for the project identified one pad mounted 300 kVA transformer to be located adjacent to the powerhouse. Currently there are two pad mounted enclosures located outside of the powerhouse. One of these is a transformer labeled at 75 kVA. The other pad mounted enclosure sits adjacent to this transformer and is not labeled and is presumably the 300 kVA main power transformer. 3 Conclusions The mechanical equipment appears in generally good condition for having sat unused for such an extended period of time. The deflector, turbine, speed increasing gear box and generator all rotate freely. However, the mechanical equipment should be disassembled and inspected before any attempts are made to operate the project. Alaska Energy Authority 6 July 30, 2010 Marathon Hydroelectric Plant Condition Assessment It is possible that the existing control panel could be refurbished to operate the plant but the relay components are obsolete and would not be useful as part of a training program. The lack of documentation of the control equipment would add significantly to the cost of refurbishment. As such, it would probably be best to replace the entire control panel with a modern unit. The shut off valve is reportedly stuck in a partially opened position. An inoperable shut off valve poses a potential safety hazard and should be remedied. Repair of the valve will require draining of the penstock. At that time, the pressure gauge tap could also be repaired and weld repairs could be made to the turbine nozzle assembly. The transmission system is not documented and it is apparent that changes have been made to the original design. As -built drawings should be created for the existing system and copies should be located in the powerhouse as well as in the City's offices. 4 Refurbishment Plan The following plan is developed for the purpose of returning the plant to productive use and maximizing the training benefits that it can provide. It is anticipated that the following work would be done under a single contract however routine maintenance and cleaning could be done by volunteer or force account labor. Intake: Clean the accumulated debris, inspect and repair as necessary the intake screens, level sensor and other components. Test the communication wiring to the plant. If the wiring has failed, consider alternative means of signaling the water level to the powerhouse, such as solar powered radio. Temporarily divert the water from the penstock at the intake and inspect visually the condition of the penstock, if practical. It was reported by City personnel that there is little debris at the intake. 2. Penstock: Visually inspect exposed portions of the penstock for corrosion. Perform limited ultrasonic inspection to assess whether there has been significant interior corrosion. 3. Turbine shutoff valve: While the water is diverted at the intake, disassemble the gate valve and operator, inspect and repair as necessary. Ream the piezometer tap and reinstall the gauge. Add a pressure transducer at the gauge piping. This may require removing the valve from the pipe. 4. Turbine case: Inspect all welds on the pressure piping for defects and corrosion, and repair as indicated to meet applicable ASME Boiler and Pressure Vessel Code, Section VIII. Turbine components: Disassemble the turbine spear and operator, needle and deflector, and inspect all bushings, journals, seals and operating mechanisms, repair as needed, and reassemble. Inspect the turbine runner in place for erosion and cracking. Disassemble and inspect the turbine shaft bearings, regrease and reinstall. Inspect the interior of the turbine housing for erosion and corrosion. Disassemble the turbine -speed increaser coupling, inspect and replace worn flex components if out of tolerance. Check alignment of gear and turbine shaft, adjust as necessary. Reassemble the turbine housing. Test the operation of the deflector trip solenoid mechanism. Alaska Energy Authority 7 July 30, 2010 Marathon Hydroelectric Plant Condition Assessment 6. Turbine control components: Reinstall the electric operator for the spear and ensure proper working order. 7. Speed increasing gear: Inspect the gear housing, bearings lubrication and cooling water circuit components. Inspect the water piping and heat exchanger for corrosion and dirt accumulation. Replace the lubricating oil. Circulate oil and verify correct oil flow to all spray nozzles. 8. Generator: Inspect and megger test windings, test surge suppressors, cable connections. Clean air intakes as accessible and inspect to determine if more thorough cleaning is necessary. Check coupling components and alignment of generator to high speed gear pinion shaft. 9. Control Cabinet and Switchgear: Remove the existing panel and replace with one built in accordance with recent new construction specifications and representative of other new hydro facilities. #I 10. Powerhouse: Clean and remove unnecessary equipment and debris. Paint piping and areas showing corrosion/degradation. Dismantle and remove un-used water supply pumps, piping and associated equipment. 11. Tailrace: Drill drain hole in vault directly below runner to allow Figure 6. Example vault to drain automatically when unit is shut down. control cabinet 4.1 Optional Upgrades The following upgrades would make the project more modern and a better training platform for operators. Replace electric operator for the spear with hydraulic cylinder and add a hydraulic cylinder for operating the deflector closing weight. Provide a small hydraulic power unit (HPU) to power both cylinders. Add limit switches and position transmitters for both the needle and the deflector, and control valves for the HPU to enable closed circuit modulation of the positions of both in response to governor and level control governors. That system would be more typical of the control systems for existing and new hydro turbines. Figure 7. Example 2. Replace the existing induction generator with a synchronous type hydraulic power unit generator equipped with the current standard excitation and voltage regulating equipment. Again, this would be more typical of existing and new hydro facilities. 3. Add extra controls in the control cabinet to allow for alternative types of turbine control such as the existing electrical spear control, and alternative hydraulic control components and for synchronizing control and voltage regulation for a synchronous generator. 4. Establish a direct communication link with AVTEC's simulation center in Seward and modify the switchgear to allow the two systems to interface. 5. Add a resistive load bank at the hydro facilities to allow for hydro training when not connected to the grid. Alaska Energy Authority 8 July 30, 2010 Marathon Hydroelectric Plant Condition Assessment 5 Cost Estimate The estimated cost for completing the refurbishment plan described above is $250,000. The estimated additional cost for providing the optional upgrades described above is $260,000. Of this, the synchronous generator and voltage control would be approximately $125,000 of the optional items, and the hydraulic, communications and electrical controls $135,000. The cost estimates include labor, materials, engineering support, contractor mobilization and profit, and contingency. Alaska Energy Authority 9 July 30, 2010
