FERC and NERC warn of elevated winter reliability risks despite adequate resources under normal conditions
Loading...
Summary
FERC staff and NERC presented a winter 2024–25 market and reliability assessment that forecasts colder temperatures, modestly higher gas prices and elevated risk of tight generation availability in several regions under extreme weather, while finding adequate resources under normal conditions.
FERC staff and the North American Electric Reliability Corporation (NERC) told commissioners that the U.S. power system is generally equipped to meet expected winter demand but could face energy shortfalls during prolonged extreme cold.
"A significant portion of North America is at risk of having insufficient energy supplies to meet demand in severe winter conditions," Robert Tallman of NERC said, summarizing the organization's winter reliability assessment. FERC staff noted Henry Hub futures for the 2024–25 winter averaged $2.95 per MMBtu, about 13% higher than last winter, and warned that drought, wildfire impacts and colder temperatures could exacerbate supply constraints.
Why it matters: Commissioners said the report underscores the continuing importance of gas-electric coordination and winterization. Staff told the commission that while all NERC regions have adequate resources under normal conditions, regions including MISO, ERCOT, SPP and parts of the Southeast face a higher likelihood of tight supply under extreme scenarios and may require operational mitigations.
Key details: FERC staff said EIA forecasts winter production near 104 BCFD, down 1% from the prior winter but above the five-year average. Power-sector gas burn is expected to decline modestly even as residential and commercial demand rises. Staff and NERC recommended enhanced generator winterization, improved communications among gas suppliers and grid operators, and planning for fuel assurance and alternative fuel arrangements where feasible.
New England considerations: Commissioners pressed staff about New England's dependence on Canadian pipeline flows and LNG imports. Staff explained that supplies from eastern Canada and the Saint John, New Brunswick LNG facility are typically contracted by local distribution companies and that contracts and storage help manage deliveries but can be affected when demand strains both regions simultaneously.
Next steps: The staff slide deck and a more detailed version of the assessment will be posted on FERC's website; commissioners asked that the report inform continued work on gas-electric coordination and related FERC–state collaborative efforts.
