RWE submits bids in Hollandse Kust West tender

The German energy company RWE is participating in the Dutch offshore wind tender for sites VI and VII of Hollandse Kust West (HKW).

The zones are located in the North Sea, approximately 53 kilometers from the Dutch coast. The sites will each provide over 760 MW of offshore wind capacity.

Furthermore, RWE’s proposed design for the HKW VI site strives to have a net positive impact on the North Sea ecosystem, while RWE’s concept for the HKW VII site is described as “a plan for the seamless integration of offshore wind farms into the Dutch energy system, including 600 MW electrolyser capacity onshore with access to storage capacity in the planned onshore hydrogen backbone.”

Revitalize the wind farm

RWE’s unique design concept for HKW VI is expected to mitigate negative effects on flora and fauna – above and below sea level – while taking significant steps to rewild the North Sea.

The company said it would build on its many years of research into existing offshore wind farms and projects currently under development and construction, such as Kaskasi in the German North Sea.

Innovations will be implemented to allow birds and bats to fly safely between the turbines and below the rotor swept area, RWE said. Additionally, RWE intends to rewild the area by adding artificial reefs and floating gardens. This is expected to improve habitat, strengthen the food chain and thus benefit all species, such as birds, fish and marine mammals.

RWE will use special vibro-piling techniques during the construction of the wind farm to minimize disruption caused by the installation of the monopile foundations.

The company will also invest in a comprehensive research and development (R&D) program with leading partners. These will include the best universities and research institutes in the Netherlands, and will foster local research on innovations and businesses, including the creation of many new research and doctoral positions. In addition, RWE plans to implement a comprehensive multi-technology monitoring system at HKW VI, and will share its knowledge widely and freely to enable all offshore wind stakeholders to do as much as possible for the ecology – by creating a so-called “living laboratory”. .

Hollandse Kust West VII and the energy system of the future

In order to meet the challenges posed by the adequacy between the fluctuation of electricity production from renewable energies and the flexibility of energy demand, RWE has drawn up a plan for the integration of offshore wind farms into the system. Dutch energy.

To this end, RWE will focus on combining the hot HKW VII offshore wind farm with 600 MW land electrolyzers for the production of green hydrogen.

In addition, the company intends to integrate electric boilers for heating, battery storage and charging solutions for electric vehicles.

Large parts of the investments are planned in the regions of Groningen and Brabant in close collaboration with partners in these regions. In addition, RWE also plans to accelerate the commercial application of new technologies by helping a large number of innovators and startups to demonstrate their innovation in an operational environment. The ultimate goal of the company is to perfectly match the energy demand to the flexible production profile of the wind farm, thus contributing to the stability of the grid.

Solutions on system integration and ecological measurements, research and knowledge sharing will be implemented with more than 40 partners, RWE said. This includes start-ups and innovators that RWE will help demonstrate their innovation in an operational environment, as well as customers and industry partners that the company will help decarbonize their businesses with new flexible demand-side investments. In addition, RWE will cooperate with universities, applied science education centers and vocational schools with regard to knowledge sharing and dissemination.

The winners of the HKW tender are expected to be announced in the fall. Besides RWE, the sites have attracted bids from Ørsted and TotalEnergies, Shell and Eneco, SSE Renewables and Brookfield, bp, and Vattenfall and BASF.
