Monitoring around Provence Grand Large records 35 to 40 dolphins per survey trip

France is using pilot projects to track potential marine impacts of floating wind structures.

The offshore renewable energy sector has experienced major growth in installed capacity worldwide.

In France, this expansion has been essential in meeting decarbonization goals and rising energy demands.

But achieving these commitments is challenging, as the nation grapples with soaring power demand fueled by electrification and industrial expansion.

The nation is now turning to floating offshore technology, focusing on how it interacts with delicate marine ecosystems.

Will these pilot projects help offshore wind developers boost marine conservation?

How France changed its energy priorities

From a long, complex history with fossil fuels to ambitious national decarbonization commitments.

The French relied on coal for more than a century before transitioning to oil and gas for power generation.

This left the nation highly vulnerable to global market shocks, as it primarily imported oil and gas to boost reserves.

Soon, nuclear power became prioritized to secure energy independence.

Yet, fossil fuels still account for up to 60% of France’s total power consumption today.

Furthermore, its imports increased to 95%, leaving the economy even more vulnerable.

As a result, the nation incorporated fossil fuel phase-out targets, with international climate commitments playing a major role.

An interim goal includes sourcing more than 41% of its final energy consumption from green sources by 2030.

But achieving these commitments is challenging, as the nation grapples with soaring power demand fueled by electrification and industrial expansion.

That is why utility-scale wind power has become so vital.

Addressing the constraints of conventional wind power

France is not the only nation struggling with this dual crisis.

That is why onshore wind capacity has been surging as the world tries to close the supply gap more sustainably.

For the French, it also plays a strategic role in diversifying its domestic power production.

But these onshore projects are now facing severe space limitations.

This has led to local opposition, land-use competition, and strict zoning laws.

Developers realized they had to seek alternative solutions to bypass these bottlenecks.

Soon, offshore wind power generation gained major traction in the nation.

Beyond addressing spatial limitations, offshore projects also benefit from high-volume electricity thanks to stronger, more consistent winds.

But as it grew more popular, competition for maritime space with commercial shipping and fishing increased.

Fortunately, floating wind structures offered a feasible deep-sea solution.

Now, pilot projects like Provence Grand Large are rising in the ocean, with marine conservation being prioritized.

A floating innovation focusing on ocean wildlife preservation

Provence Grand Large serves as a landmark milestone for France’s offshore renewable energy capacity.

The 25-MW project is located about 11 miles off the coast of Port-Saint-Louis-du-Rhône in the Gulf of Fos.

EDF power solutions launched the pilot project in the Mediterranean, which occupies water depths of roughly 328 feet.

The pilot consists of three floating wind turbines, which generate enough power to supply 45,000 homes each year.

They use a tensioned anchor-line floating system, paired with dynamic subsea cables that move with the structures.

Ensuring expansion safely coexists with local wildlife

Research and monitoring teams are closely tracking environmental indicators over a 20-year period.

For bird protection, radar tracking and 24/7 camera monitoring are used with acoustic deterrence systems.

Additionally, nearby nesting sites are being restored with the help of the Camargue Regional Nature Park.

To monitor marine mammals and biodiversity, the following are used:

• Underwater hydrophones
• Biosediment sampling
• Boat-based monitoring trips for behavior tracking

The pioneering pilot project is now completely operational.

It provides the French grid with clean power while moving toward its multi-year monitoring phase.

Initial findings have indicated that native seabirds and cetaceans frequent the site without disruption.

Should the long-term data also confirm minimal marine ecosystem impact, the project will spearhead France’s floating wind commercial future.
