Understanding Spanish Solar Compensation

What is "Autoconsumo" in Spain?

Spain uses "autoconsumo" (self-consumption) regulated by Royal Decree 244/2019. Eligible simplified compensation values exported surplus under the applicable contract or regulated mechanism, subject to its energy-value cap.

Simultaneous solar use avoids the relevant marginal import-energy cost
Exported energy is valued under the applicable compensation terms
Compensation applied to monthly bill
Simplified compensation itself does not bank unused credit; separate commercial terms may differ
Key Differences from UK/US Systems

Spanish System

  • • Net billing (not metering)
  • • Monthly settlement
  • • Wholesale compensation rates

  • • Max offset: energy charges only

UK/US Systems

  • • 1:1 credit exchange
  • • Credits roll over
  • • Can offset entire bill
