Exelon on Sept. 30 filed a petition for a declaratory order from FERC on its dispute with Constellation Energy over the latter’s effort to co-locate major loads at two of its nuclear plants.

Exelon prioritized improving "our regulatory outlook in Illinois," CEO Calvin Butler said, after the state's Commerce Commission rejected ComEd's integrated grid plan for failing to meet core provisions of the Climate and Equitable Jobs Act.

"The energy transformation will last decades, not years, which is why we are confident that investment opportunities will continue to strengthen and lengthen our rate base growth,” CEO Calvin Butler said.

Six Exelon utilities have agreed to pay ReliabilityFirst $1.8 million for violating NERC's reliability standards.

Pennsylvania regulators agreed to set guidelines for electric vehicle charging rates, with deadlines and demand charges among the key issues to be decided.

Former Philadelphia Electric Co. employee and longtime PJM stakeholder Dave Pratzon is retiring this week after a 45-year career.

PJM capped a busy week with a 90th birthday celebration that attracted utility CEOs and government officials.

PJM employee No. 13 switched off the lights of a nearly 53-year career, leaving open a position for a mentor, office prankster and Santa Claus.

Exelon said first-quarter profit exceeded expectations, in part due to strong performances by PECO, Baltimore Gas and Electric and Constellation Energy.
