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.

NRDC argued that ISO-NE’s preferred method of measuring marginal reliability impact risks under-valuing some components of clean energy resources.

NESCOE urged ISO-NE to share confidential data about fuel supply and grid reliability with FERC ahead of the upcoming winter.
