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.

PJM selected 51 projects to receive expedited interconnection studies through its Reliability Resource Initiative, adding 11,793 MW of nameplate capacity to the next study cycle.

Stakeholders urged FERC to consider reliability and consumer costs when weighing approaches to co-located large loads.

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.

Even if demand forecasts from new data centers are twice as large as what ends up being built, the growth is going to be at a scale where the power industry’s regulations need to change to keep up with it, former FERC Commissioner Allison Clements said.

The PJM Market Implementation Committee endorsed by acclamation an RTO-sponsored issue charge to consider changes to how resources committed in advance of the day-ahead market are offer capped.

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.
