SPP over one API

Southwest Power Pool runs real-time balancing market across the central US, from Oklahoma up to the Dakotas and is one of the highest wind-penetration grids in the world, with demand around 50,000 MW at peak. It settles across numerous settlement locations and hubs.

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 SPP are rolling out. Same endpoints, same JSON, just a different path segment — see the CAISO price API for the exact price shape.
