PJM Interconnection, the nation’s largest power grid system, has declared an emergency as a scorching heat dome in the South continues to expand farther north and east.
On Thursday, PJM issued a Maximum Generation Emergency/Load Management Alert, an early notification that the conditions may need the operator’s emergency procedures. This is accompanied by an Energy Emergency Alert 1 (EEA-1), which signals that all generating resources are online or scheduled to go online.
