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."

Talks to Resume in Illinois Power Plant Strike

LCG, July 24, 2001Midwest Generation, the owner of 12 coal-fired power plants in Illinois that produce about a fourth of the state's electricity, said yesterday that talks would resume Thursday with the International Brotherhood of Electrical Workers in an effort to end a 25-day-old strike at the plants.

Local 15 of the IBEW said it would meet tomorrow with the company and a federal mediator. One way or another, the two sides are expected to get together this week.

Company managers and supervisory personnel have been operating the seven baseload and five peaking plants since the union walked out on June 28. Bill Starr, business manager of the union local, said in a statement that Midwest Generation "has struggled to operate its power plants under normalcircumstances," and that Chicago-area heat and humidity will provide "an even greater challenge for the company to maintain its operations."

"That's false," a company spokesman said. "Our plants are running without problems."

Midwest Generation has offered workers a pay increase, but the union is holding out over work rules and the use of outside contractors to do some work it believes should be performed by employees. The company has said acceding to those demands would make it impossible to effectively manage its business.

Midwest Generation, a unit of Southern California-based Edison International Inc., purchased the 12 plants from Commonwealth Edison Co. of Chicago in 1999 and sells their output to ComEd.
