US Grid Operator PJM to Issue Level 1 Energy Emergency Alert Around 5pm ET

A grid emergency alert is a rare, concrete signal that power supply and demand are out of balance in the largest US wholesale electricity market, which matters well beyond utilities. It touches data centers, industrial load, and the crypto miners plugged into PJM territory, all of which compete for the same electrons. The absence of any stated cause or duration is itself the story: whether this proves a brief heat- or outage-driven squeeze or a sign of deeper strain on a grid absorbing rapid load growth is the open question worth watching.
