ISO-NE's published Fuel Mix source feed. This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.
What is physically generating in ISO-NE, in megawatts by fuel, one row per interval. 364,161 intervals, 2022-01 to now. Columns: coal_mw, gas_mw, nuclear_mw, hydro_mw, wind_mw, solar_mw, storage_mw, other_mw. Wide rather than long: a whole interval's mix is one row, so shares are computed across columns in that row and the timestamp does not repeat once per fuel. "Which fuel is largest" is greatest() across the columns, or simply reading the row.
