Data Centers Just Got Kicked Off the Grid During a Record Heat Wave
The short version: When PJM neared an all-time demand record, regulators didn't tell data centers to power down — they told them to fire up their own diesel generators instead.
Our Take
Notice what didn't happen during this near-record heat wave: no data center went dark. Instead, the DOE's emergency order let PJM order 50-megawatt-plus loads onto their own backup generators — the same diesel gensets that sit quietly in permit filings until a grid crunch turns them on for real. That's the buildout working exactly as designed: hyperscalers get uninterrupted service, and the exhaust becomes a neighbor's problem.
The rest of the roundup — an Indiana county scrambling to freeze new construction, a California courtroom fight, a $200 billion Meta campus swallowing rural Louisiana — is really the same story told three ways. Communities are being asked to sign off on massive land, water, and power commitments before they've seen what happens when the grid actually gets stressed. Now they know: ratepayers cover the summer peak risk, and the data centers get a generator fleet as their insurance policy.
