Dataset	Description
Behind-the-Meter Solar ActualNYISO · hourly	NYISO estimated behind-the-meter solar output by load zone and a published SYSTEM total at hourly resolution. NYISO releases each completed operating day on the following day, so this is a published completed-day estimate rather than a live meter reading.
Behind-the-Meter Solar ForecastNYISO · hourly forecast	NYISO day-ahead behind-the-meter solar forecast by load zone and a published SYSTEM total at hourly resolution. source_time preserves the file's real publication timestamp; compare a delivery hour only with the matching completed-day estimate, never with a sum that also includes SYSTEM.
Behind-the-Meter Solar Installed CapacityNYISO · hourly / snapshot	NYISO estimated behind-the-meter solar installed capacity by load zone. This tracks distributed PV nameplate growth over time.
Day-Ahead Implied Marginal Emission RateNYISO · hourly (DAM)	NYISO day-ahead implied marginal emission rate by zone, including CO2 and NOx rates derived from day-ahead LBMP, VOM, and implied heat rate.
