Exelon’s Constellation will pay American Electric Power $252,701 to settle AEP’s complaint over MISO’s failure to collect transmission charges from a defunct LSE.

Exelon said its Illinois nuclear plants are “up against a clock,” with the legislature unable to meet to consider withdrawing from PJM’s capacity market.

Exelon provoked ire among ISO-NE stakeholders after signaling it plans to keep its Mystic plant open after expiration of its cost-of-service agreement with the RTO.

FERC rejected ISO-NE Tariff revisions to clarify that resources retained for fuel security reasons will not be retained for other reasons once the fuel security retention period ends.

A top PJM official sought to quell concerns over an exodus from the RTO in response to FERC’s controversial order expanding the minimum offer price rule.

Exelon said a report from PJM's Monitor uses assumptions to cast a negative light on the FRR alternative members may pursue in the face of an expanded MOPR.

FERC rejected Exelon’s request to allow it the option to terminate its cost-of-service agreement to keep Mystic Units 8 and 9 in operation until 2024.

PJM’s Planning Committee will consider whether the RTO must develop document language to deal with mitigation of existing and future infrastructure.

FERC rejected transmission rate challenges against Pepco and Delmarva Power & Light that questioned the accounting of the utilities' prepaid pension assets.

Exelon is cooperating with an investigation into its lobbying of the Illinois legislature and will ensure high ethical standards in the future.
