A single unit, located in an underground powerhouse was <br />selected for economic reasons and minimum environmental impact. <br /> <br />The powerhouse cavern will be sized to accommodate a 60 MW <br />single-stage vertical reversible pump/turbine which directly couples <br />to a motor/generator. To house the pump/turbine, motor/generator, <br />and all necessary auxiliary electrical and mechanical equipment, the <br />cavern excavation will be approximately 90 feet wide, 100 feet high, <br />and 125 feet long and will require excavation of about 40,000 cubic <br />yards of rock. The machine hall will have a floor elevation of <br />approximately 9,230 feet. The powerhouse cavern will be composed of <br />two bays: the control/machine bay and the transformer bay. <br /> <br />The access tunnel wi 11 enter the powerhouse cavern at the machi ne <br />hall level. In addition to the access tunnel, two emergency exits <br />will be provided. <br /> <br />City of Gunnison, Arapahoe CO,unty, and Parker Water and Sanitation <br />District are current holders of a preliminary hydropower permit (No. <br />10449) from the Federal Energy Regulatory Commission. <br /> <br />The hydroelectric project is an integral part of the proposed Union <br />Park Water supply project. Its purpose is to provide electric power <br />and revenues needed to pump water from Taylor Park Reservoir to the <br />proposed Union Park Reservoir, and thus enhance the feasibility of <br />the proposed multi-purpose water project. <br /> <br />-8- <br />
