New York Grid Under Strain as Heat Waves Increase Demand
New York's power grid has been strained by heat waves, with the state's demand response program activated 22 times in 2025, mostly in summer. A report warns of elevated risk of supply shortfalls, while electrification and data centers could increase demand. Advocates are looking to renewable projects to ease the strain.
The NYISO's demand response program, which pays customers to cut electricity use, was activated 22 times in 2025—18 during summer months—compared to a maximum of eight activations in any single year over the prior decade. This escalation reflects how quickly extreme heat is reshaping the state's electricity landscape.
