Weather-normalized load has declined across most of New York's grid zones, but data center and manufacturing queues may change that.
NYISO's overall load has stayed flat from 2021 to 2025, even as New York City's demand grew modestly. Eight of 11 zones posted negative growth thanks to energy efficiency and behind-the-meter solar. As of May 2026, however, roughly 50 new load interconnection requests are pending, representing over 12.5 MW of new demand. Data centers, chip fabs, and advanced manufacturing portend a big change in NYISO's future, and resistance is beginning to mount.
