Description (excerpt):
This wind integration cost study, the 2GW/3GW Study, is the third such analysis of wind integration costs performed by Public Service Company of Colorado. This particular study addresses the 2 GW and 3 GW levels of nameplate wind capacity on the Company’s electric system. The prior studies examined wind penetration levels of 10%, 15%, and 20% (nameplate wind capacity divided by peak load). The focus of this 2GW/3GW study is to determine the costs of integrating 2,000 MW and 3,000 MW (nominal values) of wind energy into the Public Service electric system. The wind integration costs quantified in this study are associated with the uncertain and variable nature of wind generation. These costs are often referred to as “hidden costs.”
