NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

LCG, November 19, 2025--NERC yesterday released its 2025–2026 Winter Reliability Assessment (WRA), which concludes "much of North America is again at an elevated risk of having insufficient energy supplies to meet demand in extreme operating conditions."

Close Delayed on Two NRG Energy Plant Acquisitions

LCG, July 26, 2001-- NRG Energy Inc. said this morning that the Federal Energy Regulatory Commission has instructed its staff to convene a technical conference to "further explore issues related to the competitive effects" resulting from NRG's proposed acquisition of the Bridgeport and New Haven Harbor Stations in Connecticut.

The order directs FERC staff to report back to the Commission within 90 days after exploring "issues regarding market power concerns."

NRG has planned extensive emissions upgrades to the 660 megawatt Bridgeport plant and the 460 megawatt New Haven station, both of which it is buying from United Illuminating Co. FERC's action will delay closing the transaction beyond this summer, the original target of the companies, NRG said.

"Upon review of the FERC order received yesterday, it is clear some issues have yet to be resolved. However, NRG is confident the FERC will ultimately approve the transaction," said Craig A. Mataczynski, chief executive of NRG North America.

"Connecticut will benefit from this acquisition as it will help to ensure a healthy fuel diversity within New England's power grid so that affordable, reliable and environmentally responsible electricity is available when and where it is needed," he added.

Mataczynski said his company plans significant cuts in emission from both plants. , "NRG remains committed to reducing sulphur emissions at the New Haven facility by 50 percent and, after installing additional environmental controls, reducing sulphur emissions by more than 90 percent at the Bridgeport Harbor facility," he said.

The transaction also requires approval by the U.S. Department of Justice.
