The Energy Data API provides wholesale electricity prices per market region, grid demand and generation by fuel, and other related data. The API offers a single schema across four market structures, including AEMO NEM, Elexon GB, ENTSO-E EU zones, and EIA US balancing authorities. Data is available in integer micro units with region codes in one list. The API also includes EIA weekly petroleum inventories and derived cheapest-window signals for charging and demand response.
