Ostend (BE) | MERMAID and SEASTAR Projects intend to collaborate with Siemens Gamesa Renewable Energy as wind turbine supplier


The Mermaid and Seastar projects are amongst the last offshore wind projects to be built in the current designated offshore energy area in the Belgian EEZ. In a rapidly changing environment with a growing importance of offshore wind in the energy mix and decreasing cost levels, the Mermaid and Seastar projects adopted a combined approach for the wind turbine procurement in order to achieve the necessary economies of scale and synergies to lower the Levelised Cost of Energy (LCOE) for both wind farms.   

After intensive discussions with multiple suppliers to bring the competitiveness of their bids at a level compatible with the strongly reduced support levels, it was decided to collaborate with Siemens Gamesa Renewable Energy as  wind turbine supplier for the Mermaid and Seastar projects, with a predominant role for Ostend as offshore hub.

Parties will continue their contract negotiations with the aim to reach an agreement on the terms and conditions of a Turbine Supply Contract and a long term Service and Maintenance contract before the summer of 2018.

We are pleased to do this announcement as this will trigger a sequence of events that will eventually lead up to the construction of two offshore wind farms with a total capacity of ca. 500 MW. In order to reach project completion by 2020 the support mechanism announced by the government still has to be transposed into legislation, but we are confident the Belgian government will do its utmost to make this happen in the next weeks based on the principles agreed in October 2017.’

Green energy for 485.000 households

Subject to successful completion of the ongoing negotiations and regulatory approvals, the Mermaid and Seastar projects, will comprise 58 SGRE wind turbines, with a rotor diameter of 167m, on monopile foundations and two offshore substations connected to ELIA’s Modular Offshore Grid and provide green energy to 485.000 households. The wind turbines are expected to produce green energy as from 2020. The wind energy of the Mermaid and Seastar projects contributes to the achievement of the Belgian climate objectives 2020 and securing the future energy supply.
