According to [the French company] Normandie Hydroliennes, the grant will accelerate the deployment of one of France’s first commercial-scale tidal energy pilot projects, advancing marine renewables in the country.
The project will install four Proteus Marine Renewables’ AR3000 horizontal-axis turbines in Normandy, delivering 34 GWh annually to the French grid by 2028, enough to power 15,000 homes. The tidal energy developer’s NH1 farm aligns with France’s 2030 renewable energy targets and broader energy transition strategy.

Normandie Hydroliennes expects 80% of the project’s construction value to be sourced domestically, creating 400 direct and indirect jobs in France.
UK-based tidal energy company Proteus Marine Renewables, a key technology partner, is supplying the four AR3000 turbines for the NH1 project. The company highlighted the importance of the EU funding.

In February, Proteus Marine Renewables installed a megawatt-scale tidal turbine in the Naru Strait, Japan, making it “the first to operate such devices in two countries”.

How reliable is the production of tidal energy? Is it intermittent in production like wind power?
Well it’s extremely predictable - only dependent on cycles of the moon (and sun). In a specific location there are slack periods every six hours or so, but the phase of the waves shifts as you move along the coast a bit (not too far, on the scale of France) so these could be smoothed out by combining power from multiple locations.
Thanks to the lunar tides shifting 50 minutes every day, you’ll have great weeks where you provide maximum power exactly on-peak, followed by terrible weeks where generate exactly off-peak.
But as you said, it’s entirely predictable, which wind is only partially. You can tell years in advance when you’ll produce more, something sun and wind can’t do.
