Deliverable = signed interconnection agreement, in service by 2028, merchant (reconciled from the ISO's own queue). Existing and planned from EIA-860M.
ISO-NE looks, at first glance, like it has gas in the queue: about 6.3 GW. But every one of those projects is legacy, with online dates from 2001 to 2018. They are existing plants that remain listed, not new capacity. Filter to gas that is signed and still to be built by 2028 and the figure is zero.
New England is a well-known gas-constrained market, short on pipeline capacity into the region, and it is not adding new gas generation. For firm power the options are the existing fleet, imports, storage, and offshore wind, not new thermal build.
For a data center, ISO-NE is a small, expensive, supply-constrained market that does not offer a new firm-gas path. It belongs in the same category as CAISO and NYISO: analyze it on the demand and transmission side, not the gas-supply side.
