ERCOT over one API

Electric Reliability Council of Texas runs five-minute real-time energy market across most of Texas and is known for extreme price spikes and heavy wind output, with demand around 85,000 MW at summer peak. It settles across hubs such as HB_HOUSTON, HB_NORTH, HB_WEST and HB_SOUTH.

What you can pull

Demand — system demand (load) in MW. Hourly (EIA-930).
Generation fuel mix — MW by source (gas, nuclear, coal, hydro, wind, solar, battery). Hourly (EIA-930).
Prices (LMP) — locational marginal prices (LMP) in $/MWh. Rolling out.

Availability & cadence

Demand and the full fuel mix are available for every US grid, updated hourly from the U.S. EIA-930 feed (which publishes with a few hours' lag). Locational prices for ERCOT are rolling out. Same endpoints, same JSON, just a different path segment — see the CAISO price API for the exact price shape.
