The cost to construct the facilities, or capital cost, was estimated to be $140,000,OOO. With an installed <br />power generation capacity of 170 megawatts (MW), this capital cost represents an investment of about $825 per <br />kilowatt (kW) of installed capacity. Operating, maintenance and repair costs were estimated to be $750,000 per <br />year and off-peak pumping costs were estimated to be $9,220,000 per year. <br /> <br />Operational and financial analyses were performed to estimate the benefits arising from the hydropower project. <br />The preliminary operational analysis indicated a peak power production rate of 180 MW and annual power <br />production of 368,000,000 kilowatt-hours (kWh). The preliminary financial analysis indicated that power could be <br />produced at the site at a cost of $0.075 per kWh which would cover all of the costs associated with constructing <br />and operating the facilities and provide a 10 percent return on the investment. This is a relatively low cost for <br />peaking power. If an estimated cost of $0.01 per kWh for transmitting the power (wheeling charge) is added to <br />the production costs, it still appears as if a hydropower installation would be able to generate net positive <br />revenues. <br /> <br />V-6 <br />
