What is ISO-NE?
ISO New England · serves 6 New England states, ~14 million people
ISO New England runs the grid for the six New England states. It's a winter-peaking, gas-heavy system at the end of the pipeline network, which makes cold snaps its defining stress: when heating demand and power demand spike together, gas supply tightens and prices jump. Offshore wind off the coast is the region's big bet to change that.
ISO-NE is part of the Eastern Interconnection and runs energy, capacity, and reserve markets.
