France’s Offshore Wind: €2 Billion Spent Over 15 Years, Long-Standing Poor Track Record

France holds the second-largest offshore wind resource in Europe, but its industrial takeoff has transformed into a long administrative ordeal. Between endless procedures and overpriced contracts, the national energy transition has paid dearly for its chronic delays compared with its European neighbors.

Why a fifteen-year administrative gridlock paralyzed the start of offshore wind farms in France

Launched in May 2011, the first call for bids targeted five strategic zones such as Saint-Nazaire or Fécamp to reach 3,000 MW. Yet the reality boiled down to a generalized regulatory blockage. By 2020, only a 2 MW experimental turbine was operating off Croisic.

This slowness can be explained by the proliferation of legal challenges led by fishermen, tourism professionals, and environmental advocates. These systematic challenges stretched the execution timelines. French offshore parks thus require a decade to emerge, compared with about one third of that time for our neighbors.

The state paid dearly for this initial paralysis. During this lost decade, nearly two billion euros were spent solely to fund litigation, technical assessments, and renegotiation of contracts. Meanwhile, the national electricity grid did not receive any commercial energy from these offshore projects.

Why the old guaranteed feed-in tariffs for offshore wind weigh so heavily on public finances

The early contracts envisaged tariffs above €200/MWh, reflecting the technological immaturity of 2011 and 2013. Yet the average market price stood at €58/MWh in 2024, according to RTE. This total disconnect turned these initial agreements into heavy public subsidies.

In a March 2026 report, the Court of Audit assesses the overall commitment to renewable energy at €87 billion by the end of 2024. Fortunately, technology has evolved. The Normandy project awarded in 2022 shows a price of €44.9/MWh, proving a major drop in production costs.

A recent revival of the marine energy sector that still struggles to catch up with its northern neighbors

The situation began to unlock from 2024 with the commissioning of the Saint-Brieuc and Fécamp parks. In that year, offshore installations generated nearly 4 TWh, accounting for about 0.7% of metropolitan electricity. This start marks a historic break with the inertia of previous years.

France nevertheless lags considerably. According to WindEurope, the country reached 2 GW installed capacity by spring 2026. By way of comparison, at the end of 2025, the United Kingdom had 17 GW installed, Germany peaked at 9.6 GW, and the Netherlands reached 4.7 GW despite a smaller resource.

Moreover, the old contracts obliged the state to buy electricity even during periods of overproduction. According to the CRE, negative prices lasted 235 hours in early 2024, causing €80 million in losses. Amendments signed in June 2025 now allow stopping the turbines if necessary.

France’s energy targets for 2050 require a major acceleration of future marine projects

For the future, the roadmap sets a target of 40 GW distributed across 50 parks by 2050. However, the initial goals of the Energy-Climate Package for 2020 already anticipated 6 GW offshore, a level still not reached by the end of 2024. The accumulated delay remains difficult to close quickly.

The administrations must now optimize oversight and clarify penalties to streamline the sector. To sustain these new competitive tariffs, the government is banking on grid connections expected at Dieppe-Le Tréport by late 2026 and then Courseulles-sur-Mer in 2027 to permanently stabilize the national sector.
