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."

California PUC Rules Against PG&E Rate Proposal

LCG, Apr. 5, 2002--A ruling by the California Public Utilities Commission on Thursday will allow utilities Pacific Gas & Electric to realize cost-of-service rates for power supplied to customers from its nuclear and hydroelectric plants and numerous long-term contracts, well below rates that had been suggested by PG&E as part of its bankruptcy restructuring proposal.

The overall amount expected to be collected from Pacific Gas & Electric customers this year is $2.9 billion, while San Diego Gas & Electric will recover approximately $466 million. Paul Clanon, who heads the PUC's energy division, noted that Pacific Gas & Electric would have received $716 million more under its proposal for emerging from bankruptcy. The average cost of PG&E-supplied energy according to Thursday's ruling will be $2.8 cents per kilowatt-hour, whereas PG&E's proposal called for charges of 5 cents per kilowatt-hour over 12 years, to be followed by market-based prices.

In the opinion of Nettie Hoge, head of The Utility Reform Network, "it just highlights exactly for us why 'cost of service' is more beneficial, and how absolutely rapacious the PG&E bankruptcy plan is." PG&E said it would need more time to consider the full impact of the ruling, but PG&E spokesman John Nelson told the Sacramento Bee that the decision was "part of the piecemeal approach to rate-making that the commission has been taking -- or talking about -- for the last year."

PG&E will have further chances to submit market-based rate proposals for future years.
