ReaLCoE is an EU funded Horizon2020 project with a vision to enable direct competition of offshore wind energy with conventional energy sources in electricity markets.

This will be achieved by optimising and innovating in every link of the offshore wind energy value chain to an overall Levelised Cost of Electricity (LCoE) target of €35-50/MWh. The project will develop and demonstrate a new turbine platform that can host robust, reliable and modular Wind Energy Converters (WEC) with a rated capacity of 12+MW in a relevant offshore environment. Fifteen project partners from Europe’s key offshore markets including four renowned R&D institutes join their expertise in ReaLCoE to leverage innovations that fulfil this vision.

The consortium lead by Senvion is an integrated partnership combining multiple disciplines of the offshore sector to leverage efficiencies and cost reduction potentials. ReaLCoE will drive development, testing and certification from sequential to parallel and modular approaches. TNO contributes to this enabling much quicker times to market. The project will develop more efficient logistic and installation concepts to cope with increasing component size and weight. It will increase WECs’ operational lifetime and lower service and maintenance requirements through more robust and interchangeable components. TNO facilitates this by updating and applying its installation and O&M simulation tools. Insurance and finance experts included in the project will accompany ReaLCoE’s in depth investigation and application of business models to optimise investment and lower financial risks. Here, TNO will analyse the development of the future offshore markets and develop a vision how the market should develop to provide a long-lasting business case for offshore wind energy. Furthermore, TNO assists with the advanced implementation of digitization, reflecting the status of the physical wind turbine, to identify efficiencies and increase transparency at all levels along the value chain.

The project will install, demonstrate, operate and test a technology platform for the first prototype of a 12+MW turbine. A successful prototype operation will lead to the installation of a pre-series array in a real offshore environment towards the end of the project, to validate the concept; paving the way for modular WEC generations with superior rated capacities.
