Data Sources

Our electricity rate data is gathered from authoritative public sources. Each state page links to its specific source. We prioritize the U.S. Energy Information Administration (EIA) and state public utility commission data when available.

  • State Public Utility Commissions
    State PUCs regulate utilities and often publish rate data, tariffs, and annual reports. Data varies by state and may require manual aggregation.
  • Manual MVP (Temporary)
    Placeholder for manually curated or aggregated data during initial development. Used when automated sources are not yet integrated.
