Live conditions — New York grid

Start of day system state is NORMAL (logged 09/12/2026 00:00:00 ET; no later state change in the log)

as of 2026-09-12 22:35 UTC · source: mis.nyiso.com

The condition is NYISO’s own operating state for the New York grid — normal, a watch when reserves run thin, or an emergency. It is copied from the operator’s notices, not inferred here; where the operator publishes no feed this page can read, it says so rather than guessing.

Load — NYISO demand

Load is total demand served on the NYISO system in megawatts. Figures are the values in the export; a dash means the feed did not carry the number, not that it was zero.

Generation by fuel is a single snapshot at its own as-of time, using NYISO’s own fuel categories. It moves through the day — solar at midday, gas and storage into the evening.

Prices (LMP) — NYISO zonal prices

as of 2026-09-12 22:35 UTC · source: mis.nyiso.com

A locational marginal price (LMP) is the cost of serving one more megawatt-hour at a given node: energy, plus congestion, plus losses. The spread between the lowest and highest node is congestion on the NYISO transmission system. Negative prices mean surplus supply, usually wind or solar, at that location.

The map colours every NYISO pricing node by its latest real-time LMP. The power plant and balancing authority maps linked below show what generates inside the NYISO footprint and where its boundary runs.
