The maximum annual value for the peninsula was recorded in the summer, something that had not occurred since 2016.

In 2022, the maximum hourly demand in winter was very low, much lower than that recorded last year, coinciding with the cold snap that swept the peninsula at the beginning of January, and was even lower than the peak in 2016.

The maximum for the year was recorded in summer, specifically on July 14 between 14and 15 h. with 38,003 MWh, which represents an increase of 2.9 % compared to the summer maximum in 2021, but is 1.2 % below that recorded in 2020.

Evolution of the coverage of maximum hourly demand


Allocation of generation units based on primary fuel. The net production of non-renewable and non-Hydro Management Unit (HMU) facilities is net of their own consumption. In these types of production, negative generation indicates that the electricity consumed for the power station’s uses exceeds its gross production.
Other renewables: Include biogas, biomass, marine hydro, and geothermal.
Pumped storage: Pure pumped storage + estimate of mixed pumped storage.
Combined cycle: Includes operation in open-cycle mode.
Peninsula-Balearic Islands link: Positive value: energy input into the system; negative value: energy output from the system.
International exchange balance: Positive value: importer balance; negative value: exporter balance. Increment values are not calculated when exchange balances have different signs.
