Intermittency & Reserve Requirements
Wind (24.4% capacity factor) and solar (16.9% capacity factor) both operate well below nameplate capacity. This intermittency creates the uncertainty that NYISO's Dynamic Reserves framework is designed to address — by setting reserve requirements based on real-time contingencies rather than static rules. Assets that can respond within 10 minutes (demand response, batteries, V2G) are the most valuable under this framework.
