The average cost for electricity in NYISO was $201.89/MWh in January, up nearly 53% from January 2025 and possibly the highest ever for the month, the ISO reported.

While PJM experienced some of its highest peak loads ever during the late January winter storm, it overestimated load, with relatively high load forecasting errors, RTO officials told the Operating Committee.

DOE's senior leadership highlighted how the grid relies on fossil fuels to make it through winter peaks.

SPP says ample wind generation during the January winter storm enabled it to export as much as 3,500 MW to its neighbors in the Eastern Interconnection.

New York generators had to rely on oil as gas was scarce throughout the Eastern Interconnection during the Jan. 25-27 winter storm, NYISO said in a preliminary analysis.

The North American grid made it through the winter storm of Jan. 24-26 — dubbed “Fern” by The Weather Channel — relatively unscathed, but the cold weather gripping much of the U.S. and Canada continues, and cold snaps in the future will still stress the interconnected power and natural gas systems.

With a major winter storm bearing down on Texas, officials have assured the state that the ERCOT grid is in much better shape to take on freezing conditions than it was five years ago during Winter Storm Uri.
