FloWatt: The world's most powerful tidal farm
Located in Raz Blanchard in Normandy, one of the most energetic tidal currents on the planet, FloWatt will be the most powerful tidal farm ever deployed.
Its objective
Bring about the commercial deployment of marine tidal energy from 2026, giving rise to a new sector of the renewable energy industry in France that will play a full part in the French and European electricity mix. A new, 100% predictable carbon-free source of electricity.
Its history
Taken over by Hydroquest from 2020, the project aims to install 7 latest-generation HQ 2.5 turbines.
Joined by the energy company Qair in 2021, Flowatt continued its development until receiving unprecedented support from the French government in 2023 as part of the France 2030 plan.
The project, developed by Qair, Hydroquest and their main shareholder CMN, has received the support of the French government through an investment of 75 million euros and a preferential tariff for the electricity produced.
A project supported by:
Tidal energy:
a French energy lever
The tidal farm will provide a sustainable supply of renewable electricity for our regions using the power of tidal currents.
Predictable
A 100% predictable renewable energy: The natural movements of the tides are mainly linked to the gravitational forces of the Moon, thus guaranteeing a totally predictable production of electricity.
Powerful
High potential for available energy: with a 5 GW deposit that can be mobilised immediately, tidal power is a renewable energy with high potential. A real force for strengthening France’s energy independence.
Competitive
Energy at a competitive cost from 2030: With a production cost comparable to that of floating wind power, tidal energy will quickly become competitive and will gain a prominent place in the carbon-free electricity mix.
Virtuous
Energy with minimal environmental impact: with an extremely low impact on the marine environment and a structure that is easily recyclable at the end of its life, tidal turbines will ensure environmentally friendly renewable electricity production.
Invisible
Discreet technology: Fully immersed and moored to the seabed, the tidal turbines do not generate visual, noise or maritime disturbances.
Local
An energy at the heart of the local economy: marine tidal power will benefit SMEs and mid-caps in the region and their suppliers. The industrialisation of the sector will enable the creation of 6,000 jobs in France from 2030.

The project
in detail
A strategic alliance
Committed to responsible energy and convinced of the potential of tidal power in France and worldwide, the collaboration between the independent renewable energy producer Qair Marine and the French tidal power leader Hydroquest constitutes a strategic alliance for the worldwide development of the tidal power sector. Together with their industrial partner CMN, they are now among the leaders in the worldwide development of the tidal power sector.
Innovative and robust technology
The HQ 2.5 tidal turbine was developed by Hydroquest, in partnership with a group of French industrial, scientific and academic partners.
A robust technology, validated by the success of the 1MW turbine test project, which operated for 2 years (2019-2021) at the Paimpol-Bréhat test site in Brittany. A feat that has made it possible to certify the reliability of this technology, as the turbine has demonstrated 100% availability. The new generation benefits from feedback on this already proven concept and offers better performance. Its design has been simplified to make it lighter and it remains robust because it does not use any new components and is designed to last 25 years.
A local and efficient project
Characteristics of the pilot farm :
- Total power of 17.5 MW, thanks to 7 HQ 2.5 tidal turbines, manufactured in Cherbourg by CMN, also a partner in the Flowatt project.
- Annual production equivalent to the electricity consumption of 20,000 inhabitants.
- Local production, since 60% of the project value has already been allocated to French companies.
- Turbines close to the coast (3 km) but submerged at a depth of 30-35m, therefore completely invisible
