RWE and TotalEnergies will jointly deliver the 795MW OranjeWind offshore wind project in the Netherlands.
The latter has agreed to acquire a 50% stake from RWE in the North Sea project 53km off the coast of IJmuiden.
The pair have taken a final investment decision and suppliers have been selected for the main components.
RWE is to lead on the development, construction and operation of the site, where offshore construction is scheduled to get underway in 2026.
Full commissioning is being targeted for early 2028.
A turbine supply agreement is in place with Vestas for 53 V236-15MW turbines while Sif is to supply monopile foundations, RWE said.
Jan De Nul’s Les Alizes heavy lift vessel and Voltaire jack-up will transport and install the components, and inter-array cables are to be supplied by TKF.
RWE’s offshore wind chief executive Sven Utermöhlen said: “The Netherlands is one of our strategic core markets to grow our green portfolio.
“In TotalEnergies I am delighted to have a strong partner at our side with whom we can realise our first offshore wind project in the Netherlands and at the same time unlock the full system integration of OranjeWind.
“Together, we will provide a blueprint for the Dutch energy system of the future, designed to tackle the challenges of intermittent wind generation and flexible energy demand.
“As key players in the Dutch energy market, we are both committed to helping the Netherlands meet its decarbonisation targets.”
OranjeWind is slated to be the first system integration projects in the Netherlands, aiming to match intermittent wind power generation with flexible energy demand and contribute to grid stability.
Both companies plan to deliver system integration solutions, including electrolysers, smart charging solutions for electric vehicles, e-boilers for heating and battery storage.
TotalEnergies presidents Stéphane Michel and Bernard Pinatel said: “We are looking forward to working with RWE on a project that will enable us to develop production of green hydrogen, which we need to decarbonise our refineries in northern Europe.
“This integrated, innovative project perfectly illustrates our pioneering role in the energy transition in Europe, especially through the emergence of offshore wind power linked to green hydrogen electrolysers in the Netherlands.”
