PJM Grid Will Curtail Large Data Center Power During Shortages from June 2027

PJM Interconnection, serving 67 million customers from Virginia to Illinois, will cut power to data centers drawing 50 MW or more during grid shortages starting June 2027. Affected facilities may get just 30 minutes' notice, with compensation provided. Wholesale electricity prices on PJM's grid nearly doubled over the past year amid surging data center demand.
