The offshore wind project could deliver 300MW long-term.
The official tender pack specifies an installed-capacity range of 280-320MW, so '300MW' is the central estimate of the published target. Actual built capacity will depend on the winning bidder's foundation choice (number / size of turbines), EEZ lease-area finalisation, and Maltese grid-integration capacity. The 300MW headline is the government's planning figure, not a project-as-built guarantee.

We tested Dalli's claim against (1) the Maltese offshore wind Pre-Qualification Questionnaire (PQQ) and full tender documentation, (2) the EEZ Act 2024 establishing the legal basis for the project's lease area, (3) Energy and Water Agency strategic documentation, and (4) the EU TEN-E / CEF Project of Common Interest framework referencing the project.
Mostly True. The Pre-Qualification Questionnaire and full tender documentation specify the project's installed-capacity range as 280-320MW. 300MW is the central estimate within that range. The actual built capacity will depend on the winning bid's foundation choice (number and size of turbines), the EEZ lease-area finalisation, and how much grid-integration capacity Enemalta and the second/third interconnector together can absorb. The 300MW number is therefore a planning headline anchored in the published tender range, not a guaranteed deliverable. Limitations: 'could deliver' is the relevant qualifier — large offshore wind projects of this scale frequently see capacity adjusted between award and commissioning. Realistic delivery is into the 2030s, with intermediate-phase build-out plausible. Until financial close and final investment decision, the number is indicative.
Could Malta's offshore wind project really provide 300MW
Dalli's 'three hundred megawatts' figure is the central estimate of the official tender's specified installed-capacity range.
The official capacity range
- Lower bound: 280MW.
- Central estimate: 300MW (Dalli's quoted figure).
- Upper bound: 320MW.
The range exists because tender bidders propose specific designs (turbine model, number of turbines, foundation type, lease-area utilisation). The 280–320MW band gives bidders flexibility to optimise within capacity constraints set by lease area and grid integration.
What 300MW means in Malta's grid context
Putting 300MW into perspective:
- Malta's peak summer demand in 2023 was 663MW. By 2026, it has climbed further (likely 700MW+).
- Malta's installed solar capacity at end-2024 was 252MWp DC (~238MW AC). 300MW of offshore wind would roughly match Malta's entire current solar fleet.
- Each Maltese gas-CCGT plant is 215MW.
- Each interconnector cable is 200MW.
300MW of offshore wind would therefore be larger than any single existing electricity asset on the Maltese grid. At a typical Mediterranean offshore-wind capacity factor of 35–45%, that translates to ~1.0–1.2 TWh per year of generation — close to Malta's full annual gas-CCGT generation today.
Why 'long term' matters in the framing
Dalli specifically described it as a long-term project. The realistic timeline:
- Tender award: late 2026 / early 2027.
- Final investment decision and EIA: 2027–2028.
- Construction: 2028–2030.
- Commercial operation: ~2030 at the earliest, more likely 2031–2032.
So 300MW is a 5–7 year-out figure, not a near-term contribution. Malta's interim energy security still rests on the gas-CCGT fleet, the existing interconnector, the planned third interconnector, and continued solar deployment.
Risks to the headline number
Several factors could pull the actual built capacity below 300MW:
- EEZ lease-area finalisation may turn out smaller than planned, constraining turbine deployment.
- Grid-integration capacity (how much Enemalta plus the new interconnector can absorb) may cap injection below 300MW.
- Project economics — floating-wind capex is still a young technology cost-curve, and bidder economics may favour the lower bound.
- Environmental constraints from EIA could limit certain turbine positions.
Each of these would push the actual delivered capacity towards the 280MW lower end rather than the 320MW upper end.
So is the claim accurate?
Order-of-magnitude yes, with appropriate caveats. The 300MW figure is the government's central planning estimate, anchored in the official tender's 280–320MW range. The actual built capacity will be set by the winning bid and a long sequence of subsequent decisions. Mostly True — the figure is real and supported, but it's a planning target, not a delivered reality.
