DEMOGRAVI3 is a project that aims to develop an innovative gravity based foundation for offshore wind turbines. EDP has just been granted European funding for the project.

The DEMOGRAVI3 project by EDP will be funded by the European Commission’s Horizon 2020 programme through a € 19.2 million fund. The project will last for four years and will include a full-scale demonstration in a real-life environment off Aguçadoura, Póvoa de Varzim, in northern Portugal.

DEMOGRAVI3 will test a wind turbine with an innovative gravitational foundation made of concrete and steel. This turbine will be installed on the Aguçadoura Offshore Wind Demonstration Farm, about 6 km off the Portuguese coast, taking advantage of the underwater cable connecting the WindFloat turbine to a substation on land, which will be decommissioned meanwhile to make way for Phase 2 of the project, to be installed in Viana do Castelo. The consortium developing this new project will be coordinated by EDP, through EDPR.

DEMOGRAVI3 will be installed on the seabed, although it will already be assembled and floated to the mooring place. The whole structure of the turbine and its constituent elements will be assembled on shore and then transported. The main innovation of this structure thus avoids the necessity for heavy lift vessels to anchor and assemble all the turbine components in an offshore environment.

According to António Mexia, CEO of EDP, "This initiative strengthens EDP’s commitment to an emerging area of wind production with strong growth potential. By increasing competitiveness and their contribution to the fight against climate change, the installed capacity of renewable energy will tend to grow faster than in recent decades, and oceans will play a key role in this expansion".

The total budget for the project amounts to € 26.8 million.
