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." The WRA does state that resources are adequate for normal winter peak demand, but extended, wide-area cold snaps will be challenging.

California Rewrites Contracts with Williams Cos.

LCG, November 12, 2002-California officials and energy company Williams Cos. reached a settlement yesterday, yielding the state $417 million.

In 2000 and 2001, Californian energy purchasers signed $43 billion in long-term energy contracts, estimated to be roughly twice the price necessary.

California Attorney General Bill Lockyer brought lawsuits against several energy companies earlier this year, alleging contract prices were unfairly high.

Williams Cos. agreed to pay California $417 million, which includes renegotiating its 10-year contract with the state by $180 million. The deal also includes yielding the state six turbines, worth $90 million, putting $150 million to energy efficiency, and giving $80 million to projects for solar energy in California schools. $147 million will go to state agencies over eight years. Reports on the allotment of funds are unclear as to how all these projects' costs add up to $417 million, but Lockyer has said that the net effect could be as large as $1.4 billion.

As part of the settlement, Williams Cos. will also pay Oregon and Washington each $15 million over three years.

While the $417 million is being touted as a major victory for the state, some Californians may wonder from where the remaining $21.6 billion in alleged overcharging will come.

The settlement still faces court and regulatory approval.
