In the month of August, electricity demand was 25,688 GWh, down compared to the same month the previous year (-1.1%) and compared to August 2021 (-3.6%). There was also an increase in foreign exchange (+19.0%) compared to the same month in 2022. In 2023, electricity demand (206,282 GWh) increased compared to the same period in 2022 (-4.5%) and compared to the cumulative figure for 2021 (-2.9%). The value of electricity demand was achieved with the same number of working days (22) and with an average monthly temperature approximately 0.6°C lower than August last year. When adjusted for seasonal and temperature effects, the figure represents a +0.7% variation.

The annual trend for August 2023 (compared to August 2022) was null (0.0%) with raw data. In August 2023, electricity demand was met 43.3% by production from Non-Renewable Energy Sources, 43.8% via Renewable Energy Sources and the remainder via foreign exchange. In 2023, electricity demand was 206,282 GWh, 46.7% of which was met via production from Non-Renewable Energy Sources, 36.9% from Renewable Energy Sources and the remainder from the foreign balance.

In August, production from Renewable Energy Sources increased (+27.2%) compared to the same month of the previous year. Specifically, there was an increase in renewable hydroelectric production (+49.8%), in wind production (+43.8%), and in photovoltaic production (+19.8%). In 2023 the operating capacity of renewables increased by 3,470 MW. This value is 1,733 MW higher (+100%) compared to the same period of the previous year.

The August total for withdrawal

programmes on the DAM was approximately €2.6 Bn, down 15% compared to the previous month and up 80% compared to August 2022.

In August, the spread between average bid- up and bid-down prices on the DSM was €124/MWh, down by 2% compared to the previous month and by 60% compared to August 2022.

Total volumes were down compared to the previous month (-25%).

In August, the spread between bid-up and bid-down prices on the Balancing Market was €144/MWh, up by 19% compared to the previous month (€121/MWh) and down compared to August 2022 (€519/MWh; - 72%). The total volumes increased slightly compared to the previous month (+3%).
