Just one day before scheduled retirement, the Department of Energy ordered Constellation to delay shutting down its Eddystone peaker units, citing reliability concerns across the PJM grid. (Utility Dive)

The delay could ripple through Constellation’s $16.4 billion Calpine merger, as the company had planned to sell other PJM assets to ease market power concerns.
