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."

Reporting to Energy Price Index Publications Falls Off

LCG, Nov. 15, 2002--Traders at a number of large energy companies have begun not to provide any price data concerning their transactions to industry publications, and in some cases are releasing the information themselves through their risk oversight units.

The likely result of the change in reporting patterns is to make the price indexes less representative and reliable as a source of market information. William Hogan, a professor at Harvard University who serves as director of research for the Harvard Electricity Policy Group, told the Wall Street Journal, "The tradeoff here is between easy access to imperfect information and difficult access to better information. It's not completely obvious to me which one is beter and which is worse. There is a real danger here that everybody decides to clam up."

Regional differences in the numbers of deals taking place will affect some indexes more than others, where the published indexes are concerned. One of the most widely known set of indexes is published by Platts, a company owned by McGraw-Hill Cos. Both electricity and natural gas, for which trading volumes are greater, have experienced changes. Constellation Energy Group, El Paso, Reliant Resources Inc., PPL Corp., Williams and CMS are no longer reporting prices in any way.

While some companies have disclosed that false prices were submitted to index publishers by their traders and are now cooperating with federal authorities, others who may fear being subpoenaed appear to have decided it is less risky to simply not report should they make an error in reporting. "If you start losing the price transparency, it creates advantages for big companies and probably leads to higher prices," said Phili Verleger Jr., an economic consultant in Newport Beach, Calif.
