Abstract
The Electricity Innovation Institute (E21) and the Electric Power Research Institute (EPRI) propose two standard cost estimate methodologies, a utility generator (UG) and a non utility generator (NUG) methodology, including a set of financial assumptions, to evaluate the economics of offshore wave power plants. The E21 EPRI Project Team will use these methodologies to evaluate the economics of both a 1,500 Mega Watt Hours Electric per Year (MWeh/yr) pilot plant and a 300,000 MWeh/yr commercial size plant (500 kW and 100 MW at 40 capacity factor respectively).
Regulated utilities are permitted to set electricity rates (i.e., collect revenue) that will cover operating costs and provide an opportunity to earn a reasonable rate of return on the property devoted to the business. This return must enable the UG to maintain its financial credit as well as to attract whatever capital may be required in the future for replacement, expansion and technological innovation and must be comparable to that earned by other businesses with corresponding risk.
