What this index measures

The EnergyIndex Wind series tracks onshore and offshore wind generation in the United States. Wind is the largest renewable source on the U.S. grid, and its month-to-month swings drive power prices in Texas, the Plains and the Midwest.

Who uses it

  • Wind developers and landowners
  • Grid operators and power traders watching seasonal supply
  • Students and journalists covering the energy transition

Methodology

  1. Source. U.S. Energy Information Administration, Electric Power Operational Data, monthly net generation, fuel type WND (wind (all sectors)), location US, sector 99 (all sectors). Units: thousand megawatt-hours, shown here as GWh.
  2. Share. Source generation divided by all-fuels generation (ALL) for the same month.
  3. Index level. Trailing-12-month generation divided by total generation in calendar 2020, times 100. 2020 = 100. A level of 150 means the last twelve months produced one-and-a-half times what 2020 did.
  4. Revisions. EIA revises recent months; we re-pull every six hours and restate without notice. The most recent month is preliminary.
  5. What this is not. Not a price, not a security, not investment advice. Nothing on this site is for sale or trade.

Latest data month: July 2026. Retrieved from EIA API v2.
