Evaluating wind capacity value in New York and California

A conventional detailed reliability analysis is used to evaluate the capacity value of new generation based up location and forced outage rates. Adaptation of those methods can show the capacity value of additional wind generation. However, it would also be helpful to have an easier, faster methodology to estimate the capacity value of wind generation. Analytical results from both a detailed reliability analysis and from an approximate technique are presented. The locational and chronological aspects associated with evaluating intermittent non-dispatchable generation such as wind are discussed. Examples from two recent large-scale wind integration studies in New York and California are presented.
