  Energy and Utilities is a topic profile in the API Evangelist Network
  cataloging the API surfaces that move data across the modern electricity,
  gas, and water value chain. It indexes utility data integration APIs,
  grid and wholesale market operator APIs, federal energy data programs,
  renewable energy research APIs, weather APIs that drive grid demand and
  solar forecasting, EV charging interoperability protocols, and the
  Green Button family of customer energy data standards. The repo
  provides a baseline catalog plus shared semantics (JSON Schema,
  JSON-LD, vocabulary, examples) for the meter reading / energy data
  point that ties every one of these surfaces together.

    description: >-
      Third-party platforms that authenticate against retail electric, gas,
      and water utilities to retrieve customer meter, interval, and billing
      data on behalf of a consumer or business. These APIs collapse the
      thousands of US utility back-office systems into a single REST
      surface, typically aligned with the Green Button standard.
