Malta’s electricity supply rises 3.2% in 2025 as demand also increases

Malta’s electricity supply increased by 3.2 per cent in 2025, reaching 3,207.1 GWh, according to figures published by the National Statistics Office (NSO).

Average electricity demand increased by 2.9 per cent to 492 MW. The highest monthly demand was recorded in July, at 637 MW, followed by August at 585 MW. July also recorded the highest electricity supply during the year, at 362.6 GWh, followed by August with 334.6 GWh.

Electricity demand typically peaks during the summer months, when Malta and Gozo experience periods of particularly high demand amid extreme temperatures. In July of this year, the Government said electricity demand had reached a record 741MW, surpassing the previous peak of 663MW recorded in summer 2023.

Currently, Enemalta is relying entirely on local electricity generation, as the Malta-Sicily Interconnector (IC1) has been temporarily switched off due to ongoing works in Sicily related to the second interconnector. This then, raises the question if this move was made at the right time and whether all factors were considered, especially when temperatures are still a bit high.

According to the NSO, electricity imports rose by 6.2 per cent to 1,031.0 GWh and accounted for 32.1 per cent of total electricity supply. Power plants generated 1,858.3 GWh, an increase of 0.5 per cent over 2024.

Renewable electricity generation increased by 8.1 per cent to 363.4 GWh, with renewable sources accounting for 11.3 per cent of total electricity supply. Photovoltaic installations accounted for 96.8 per cent of renewable electricity generation.

The increase in electricity supply was accompanied by a 2.4 per cent decrease in greenhouse gas emissions from fuel combustion at power plants compared with 2024.

Overall, electricity supplied in 2025 increased at a slower rate than in the previous year, when supply had risen by 6.5 per cent.

During the summer, Gozo experienced prolonged power cuts after faults affected two cables supplying electricity to the island. The outages occurred during a heatwave affecting the Maltese Islands, with tourism operators describing this situation as "embarrassing" and one that "affects Malta's image."

BusinessNow.mt had spoken to tourism operators in Gozo to discuss the situation.

Diane Falzon, owner of il-Kartell restaurant in Marsalforn, described the situation as “disastrous and embarrassing,” while Arzella restaurant owner Christian Grech said that “to lose a Saturday, at the end of the month when wages are due, is a loss of a lot of fund.”

Earlier this year, Enemalta issued a call for interest for potential economic operators for the design and construction of a new 132kV electricity connection between Malta and Gozo.

The proposed project involves a submarine cable of around 20 kilometres, together with land-based sections on both islands, connecting Baħar iċ-Ċagħaq near Magħtab with Għajnsielem in Gozo.
