Malta has over 1GW (1,000 MW) of available energy capacity.
Adding up Malta's electricity capacity stack — Delimara CCGT 215MW + ElectroGas CCGT 215MW + Marsa standby ~150MW + Malta-Sicily interconnector 200MW + ~250MW solar PV (AC nameplate) + small private generation — aggregate nominal capacity exceeds 1GW. Honest caveat: not all of this is firm or simultaneously dispatchable — solar yields drop to zero at night and the interconnector is hard-capped at 200MW until the second cable is built.

We tested Dalli's claim against (1) Enemalta plc capacity stack disclosures, (2) Energy and Water Agency installed-capacity records, (3) ENTSO-E Transparency Platform Maltese generation register, and (4) NSO solar PV capacity data.
True. Adding up Malta's electricity capacity stack: Delimara CCGT 215MW, ElectroGas CCGT 215MW, residual Marsa diesel/gas standby ~150MW, Malta-Sicily interconnector 200MW, and 250MW AC solar (267MWp DC) brings nameplate capacity to ~1,030MW. Plus small private generation (commercial backup, microgeneration). Against a peak demand of 663MW (July 2023), there is substantial nominal headroom. Limitations: capacity is not the same as firm dispatchable supply — solar yields fall to zero at night and the interconnector has a hard physical limit at 200MW until the second cable is built. So the firm dispatchable capacity available at peak (typically late-evening summer) is closer to ~780MW (CCGTs + Marsa + interconnector) than the headline 1GW figure. The 1GW number is correct as installed capacity, but listeners should not infer 1GW of always-available power.
Does Malta really have over 1 gigawatt of available energy capacity
Dalli's headline: over 1 gigawatt of available energy capacity, against a peak demand we already know hit 663MW in July 2023. The arithmetic is sound. The interpretation needs care.
What Malta's capacity stack actually looks like
Aggregate nameplate capacity sits a hair above 1 GW. Dalli's headline is right by simple arithmetic.
The crucial caveat — capacity vs. firm supply
Capacity is not the same as supply you can dispatch any moment. Three constraints matter:
- Solar yield is zero at night. Malta's 250MW AC solar nameplate produces nothing between sunset and sunrise — exactly when winter peak demand can occur. Effective firm contribution from solar overnight is 0MW (without storage, which Malta is starting to build but doesn't have at scale).
- The interconnector has a 200MW hard limit. Until the planned third cable is in place, any single fault on the interconnector — like the March 2022 anchor incident — knocks 200MW out instantly. The 200MW figure is also a soft cap during summer at peak demand on the Sicilian side.
- Marsa is reserve-only, not first-call. Its 150MW is meant for emergency cover, not regular dispatch.
Strip out the non-firm and reserve-only elements and Malta's reliable, daytime-and-evening dispatchable capacity is more like ~830MW (two CCGTs + interconnector + solar contribution at peak). At night without solar it falls to ~630MW. Compared to 663MW peak observed in July 2023, the headroom on a hot July evening with solar still contributing is real but not vast.
What about the future?
Three projects in the pipeline materially change this picture: the third Malta–Sicily interconnector (initially 200MW, scalable to 400MW per Abela's claim at the same press conference), the offshore wind farm in the EEZ (280–320MW once built, late-decade), and a planned ~200MWh battery storage system that would shift solar yield into evening peak hours.
So is the claim accurate?
Yes. Malta's nominal installed capacity is over 1 GW and the arithmetic is straightforward. The honest reading of that headline is: substantial nominal capacity, but a meaningful share is non-firm or reserve-only, so headroom over peak demand is more modest than the topline implies.
Verdict: True.
