Utilities in North America

59 utilities providers across North America, publishing 110 APIs.

59 providers 110 published APIs 220 indexed documents

Utilities across North America — 59 providers on the APIs.io network sit in both cohorts, and between them they publish 110 indexed APIs.

34 of the 59 publish at least one machine-readable API; 25 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 21 emerging, 18 minimal, 9 thin, 8 developing, and 3 strong.

Leading by rating: OpenADR Alliance, Green Button Alliance, Hydro-Québec, Pacific Gas and Electric, MISO, Virtual Peaker, and 53 more.

Region membership is derived from three explicit signals — a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. This is a map of stated headquarters, not of markets served.
