the project submitted to the inquiry :

In line with European policy, France has embarked on a programme to combat climate change based in particular on the diversification of its energy system and growth of renewable energy. The Energy Transition Law for Green Growth of August 2015, amended in November 2019 by the Energy and Climate Act, sets ambitious national targets for 2030, including:

  • 33 % renewable energy in the overall final energy consumption ;
  • 40% of electricity production from renewable sources.

To meet these targets, France has embarked on an ambitious programme to build offshore wind farms along its various coastlines.

The offshore wind farm project off Dunkirk and its electrical connection are located in the Nord department (59), in the Dunkirk urban community.

The wind farm will be located more than 10 km off the coast of Dunkirk, and more than 11.4 km off the coast of the seaside towns on either side of the border with Belgium, covering an overall area of no more than 50 km². It will comprise a maximum of 46 wind turbines with a total maximum output of 600 MW (megawatts). Turbines will be installed on monopile foundations and connected to an offshore substation by a network of inter-turbine cables. The offshore wind farm will generate around 2.3 TWh (terawatt hours) of electricity per year, equivalent to the annual electricity consumption of almost one million people.

A maintenance base for the offshore wind farm will be built in Dunkirk, within the boundaries of the Grand Port Maritime de Dunkerque (GPMD), to operate and maintain the wind farm for 30 years.

Electrical connection of the wind farm includes a maritime section - located on the one hand on the State's natural maritime public domain and on the other hand on the State's maritime public domain administered by the GPMD. It comprises an offshore substation and a double 225,000-volt submarine link of around 17 km linking the offshore substation to the landing zone in the municipality of Dunkirk (Mardyck). It also comprises an onshore section in the municipalities of Dunkirk (Mardyck) and Loon-Plage - a double underground electricity link of around 6.5 km to an onshore substation in the industrial port zone, which is itself connected to the existing electricity transmission network nearby via two double 300-metre overhead links.
