In 2025, the electricity supplied amounted to 3,207.1 GWh, an increase of 3.2 per cent when compared to previous year, the NSO said Thursday.

The statement was ironically scheduled to be published today, on the same day that many localities in Malta and Gozo suffered a power cut.

During 2025, the electricity supply in Malta comprised of net generation from power plants (56.5 per cent), supply from net imports (32.1 per cent) and renewable sources (11.3 per cent), the NSO said.

In 2025, the gross production consisting of the electricity supplied from power plants and from renewables amounted to 2,221.7 GWh. The month of July featured the highest amount of gross production with 239.7 GWh.

Electricity production from power plants registered an increase of 0.5 per cent when compared to previous year amounting to 1,858.3 GWh. Energy harvesting from renewable sources registered an increase of 8.1 per cent, reaching 363.4 GWh in 2025. Most of the renewable energy (96.8 per cent) was produced from photovoltaic panels.

During 2025, a total of 1031.0 GWh were imported through the interconnector, registering an increase of 6.2 per cent when compared to the previous year.

The month of July (362.6 GWh) had the highest amount of electricity supplied during 2025 with a share of 11.3 per cent. This is followed by the month of August (334.6 GWh) having a share of 10.4 per cent from the amount of electricity supplied.

The months of July and August featured the highest electricity demand, registering 637 MW and 585 MW respectively during 2025. The annual average demand registered in 2025 was that of 492 MW - an increase of 2.9 per cent when compared to the previous year.

In 2025, GHG emissions from fuel combustion in power plant sources decreased by 2.4 per cent over the situation in 2024.
