The project will now consist of 62 8MW machines, giving a total capacity of 496MW, slightly down from 500MW. Nevertheless, Ailes Marines expects to see a 7% increase in productivity by using the larger turbines. The consortium will apply to the energy minister next week to approve the change.
Following site studies, the consortium said in June it was considering using gravity-based foundations instead of jackets, a move strongly opposed by local fishermen.
However, Ailes Marines now says it will be able to use jackets, given the smaller number of turbines, while staying within the project cost of EUR 2 billion.
The turbines will be built at Areva's planned factories in Le Havre, with production scheduled to start in 2018. St-Brieuc is scheduled to come online in phases from 2018 to 2020.
