Maximum Demand
Information based on provisional data as of January 2024
The maximum annual value for the mainland was recorded in the winter, while last year's occurred in the summer.
In 2023, the maximum hourly demand in the winter was higher than last year’s, although it is well below the historical maximum and that of 2021, which coincided with the cold snap that swept the mainland at the beginning of January.
Annual evolution of peninsular instantaneous demand peaks
All-time winter high: December 17, 2007.
The annual hourly maximum was recorded on 24 January between 20-21 h, at 38,615 MWh, which represents a 2.2 % increase compared to the winter maximum in 2021, but is below those recorded in 2019 and 2020. Last year's maximum hourly demand was recorded in the summer. This year, however, the summer maximum is 3.1 % lower than last year.
