SPP and MISO warned of a reliability crisis if the EPA's proposed Clean Power Plan isn’t eased to account for up to 134 GW of generation retirements by 2020, most of them coal-fired units.

FERC denied Consumers Energy’s request for a waiver from MISO’s must-offer requirement, three weeks after approving a similar request by IPL.

FERC approved IPL’s request for a limited waiver from MISO’s must-offer requirement, relieving the company of having to purchase replacement capacity after its coal-fired Eagle Valley units retire in 2016.

Generators that planned to retire coal-fired units ahead of the EPA's MATS extension deadline say they may accelerate retirements to avoid MISO penalties.

PJM is adding more items to the to-do list resulting from the September heat wave, during which officials ordered limited load sheds to prevent a wider transmission collapse.

Briefs from federal agencies governing PJM Interconnection and other national organizations. This week's news include stories from the Energy Information Administration, the Environmental Protection Agency, the Supreme Court and the DC Circuit Court.

Maryland and Delaware joined six other Eastern states in asking EPA to impose tighter controls on nine “upwind” PJM states they say are sending pollution over their borders.
