In New England, increasing winter reliability concerns are driving questions about how long the region’s aging fleet of oil-fired power plants can, or should, remain on the system.

While NYISO operated reliably last winter, the season provided “continued examples of limited flexibility on the gas system,” ISO staff told the Operating Committee.

PJM has requested that Talen Energy continue operating a portion of its H.A. Wagner Generating Station an additional three years beyond its requested 2025 deactivation date.

ISO-NE presented the final stage of its Operational Impact of Extreme Weather Events study to stakeholders at the NEPOOL Reliability Committee on Nov. 14.

Transmission upgrades that are needed to avoid overloads in a fully electrified New England by 2050 could cumulatively cost between $22 billion and $26 billion, ISO-NE told its Planning Advisory Committee.

ISO-NE fossil fuel generators burned 6 million gallons of oil during the recent heat wave, resulting in a 50% emissions spike over the same period in 2021.

The Northeast U.S. could meet its winter peak power needs with LNG rather than relying on oil or coal plants, argues a Houston-based entrepreneur.

FERC approved an agreement between Dynegy and its Office of Enforcement to settle allegations that the company misrepresented its plants' ramp rates to PJM.

Limited fuel supplies put the New England grid at heightened risk of emergency actions — including controlled outages — this winter, ISO-NE said.

The military has been among the leaders in seeking to make its facilities more resilient and adding renewable power, energy storage and microgrids.
