According to figures from the Belgian Offshore Platform (BOP), the country’s offshore wind farms produced less electricity in 2025. BOP says that this is due to weaker winds over the North Sea.
Total output for the wind farms in the Belgian sector of the North Sea reached about 6.6 terawatt-hours (TWh). This was enough to provide 8.2% of Belgium’s electricity needs. However, output was lower than in 2023 (a very windy year) when 8 TWh was produced. In 2024 this was 7.1 TWh. The fall in output last year was caused by lower wind levels.
Belgium currently has nine offshore wind farms that have a combined capacity of 2.26 gigawatts (GW). This places the country in Europe’s top five when it comes to offshore wind energy production capacity. Only the UK, Germany, the Netherlands and Denmark are able to produce more energy from offshore windfarms.
Meanwhile, three new off-shore wind farms are planned in the Princess Elisabeth Zone. Once up and running they could raise Belgium’s offshore wind capacity to up to 5.8 GW. BOP calls for faster progress to be made on the construction of the wind farms, noting that work on the offshore grid is already under way.
BOP stresses that offshore wind energy remains a key source of affordable, locally produced renewable energy, thanks to low maintenance costs and the long-term stability in the cost of the energy produced.
