Estimation methods

This document outlines the estimation methodologies that electricityMap uses to create the most accurate and useful data possible.

Estimation models

• Time Slicer Average is used for filling holes where data is missing from the provider.
• Real-Time Estimations is a hierarchal estimation model that uses external forecasts then internal forecasts, and lastly falls back to Time Slicer Average if both the external and internal forecasts are unavailable. Limited to solar and wind forecasts for now.
• Construct Breakdown is used to construct production breakdown for zones where real-time, hourly data is unavailable.
• Reconstruct Breakdown is used to re-construct production breakdown for zones where the real-time hourly data we obtain from public sources is either too unreliable or incomplete to be integrated as is into electricityMap.
• Zone specific models:
  • AE & OM & QA: United Arab Emirates, Oman, Qatar
  • CH: Switzerland
  • IE & GB-NIR: Ireland and Northern Ireland
  • IN: India
  • JP: Japan

Estimated zones

For now, only specific zones are estimated, but we are constantly working on expanding the list 🌍
