Monthly Electricity Statistics
Highlights and data explorer of monthly electricity production and trade data for all OECD member countries and electricity production data for a selection of other economies
Highlight of the month
In July 2026, Spain’s electricity consumption reached 24.9 TWh, up 2.0 TWh (8.8%) year-on-year from July 2025. The increase coincided with particularly high cooling demand, which reached 166.5 CDD21 (cooling degree days with 21°C threshold temperature, population weighted average).
Electricity consumption in Spain shows a clear seasonal pattern, with two peaks typically observed during the year. The summer peak, around July, coincides with higher cooling demand, while the winter peak, around January, coincides with higher heating demand. The evolution of cooling degree days (CDD21) and heating degree days (HDD14) shown in the chart illustrates this seasonal relationship.
Electricity consumption here is calculated as electricity available: indigenous production plus imports, minus exports, electricity used for pumped storage, and transmission and distribution losses.
