Story details

On October 12, the Department of Energy announced an emergency order directing PJM Interconnection to dispatch specified generating units as needed to maintain reliability. The agency cited elevated demand, a high rate of planned generator outages during autumn maintenance, and planned transmission outages in the region.

The order is effective October 13–16, 2026. PJM may call on backup generation as a last resort before or during an Energy Emergency Alert 3. DOE estimated that more than 35 gigawatts of unused backup generation is available nationwide; that figure is not a regional capacity total for this order.
