FERC approved Constellation's purchase of Calpine, which will create an even bigger IPP with nearly 60 GW around the country, with the biggest share of that in PJM.

Calpine proposed that NYISO split its 24-hour-only transmission congestion contracts into on-peak and off-peak products, arguing it would reduce the cost of congestion hedging by better aligning it with load and generation behavior.

As part of its review for the Constellation-Calpine merger, DOJ asked PJM for a major trove of market data as it looks into the region where the two firms' operations overlap the most.

Rapid demand growth within ERCOT was a major point of discussion at the Gulf Coast Power Association's recent Spring Conference.

Two power industry CEOs at the Gulf Coast Power Association’s spring conference offered two different takes on ERCOT load growth over the rest of the decade — and how the sector should deal with a potential doubling of peak demand by 2031.

FERC received several protests to Constellation's proposed purchase of Calpine, with PJM's Monitor arguing the companies need to make additional commitments to preserve competition in the RTO.

PJM’s Markets and Reliability Committee endorsed two proposals to revise the RTO’s ELCC formula to add two new generation categories and limit the penalties resources face if their accreditation declines between auctions.

PJM’s Market Implementation Committee narrowly endorsed a PJM proposal to use ELCC to model the availability of demand response resources in all hours, along with other changes to how DR accreditation is determined.
