Our wind farms on the open sea

A strong tailwind for the energy transition 

Strong wind is one of the most powerful natural forces on planet Earth – and it is thus also a powerful source for generating climate-friendly energy. The principle is that wind gusts set the three rotor blades in motion, which in turn drive a generator, the electricity from which is fed directly into the grid.

In many countries, wind power is already making an important contribution towards the generation of electricity from renewables, and the numbers are rising. We are therefore proud to be one of the world’s largest owners and operators of onshore and offshore wind farms.

And we want to keep on growing in this dynamic market – both alone and in collaboration with partners.

How does an offshore wind farm take shape? 

RWE Renewables has first-class resources, experience and expertise, so it can cover the entire wind energy value chain from development through to construction and operation.

Our integrated business comprises the entire lifecycle of offshore projects.

We achieve several milestones along the way to final commissioning:

We are no. 2 worldwide in offshore wind farms

RWE owns and operates offshore wind turbines throughout Europe representing a total of 2.4 GW. RWE Renewables is therefore uniquely positioned and predestined to drive the energy transition forward, as well as to play a leading role in the sector at an international level.

The goal is to achieve grid capacity of 8 GW by 2030. By taking part in additional auctions in Europe, the Americas and the Asia-Pacific region, RWE has a number of complex Offshore projects ahead of it. The largest construction projects include the windfarms Kaskasi (342 MW) and Sofia1 (1,400 MW). New offshore markets, e.g. Japan and Taiwan, will make a substantial contribution towards our world-leading position from 2024.

Are you generally interested in our wind sites? No problem! On our global map you will find an overview of all offshore and onshore operating locations and projects.

Unique market opportunities 

RWE Supply & Trading, our international trading house, functions as the link and hub connecting the wind turbines with customers. In the offshore area, we are looking to achieve an appropriate track record for the conclusion of power purchase agreements (PPAs).

There are major opportunities for growth in wind power sales across the entire technology range.

Rotor blade recycling

At its Kaskasi offshore wind farm, RWE tests the world’s first recyclable wind turbine blade 

The Kaskasi offshore wind farm (342 MW) will be constructed in the North Sea off Germany, 35 km to the north of the island of Heligoland. Most of its components are already made from recyclable materials. The turbine blades, developed by Siemens Gamesa, are recyclable, thanks to the use of a special resin.

There are four stages in this process

  • Rotor blade recycling - decommissioning at the end of service life | Offshore Wind at RWE

Job creation

Construction work for installing the electrical plant alone will create about 500 full-time positions. The benefits will also be felt by local businesses in the areas of accommodation, logistics, catering, and office supplies.

Supporting communities | Offshore Wind at RWE

Supporting communities

During onshore construction, local communities will receive £500,000 from the construction fund. A further £40,000 per year will be made available for areas adjacent to above-ground electrical infrastructure (onshore substation) and landfall locations.

Animal protection

We are focusing on measures to protect marine mammals and spawning black bream, and also animal life on land, especially badgers, bats, birds, invertebrates and reptiles.

Support for fisheries | Offshore Wind at RWE

Support for fisheries

A working group for commercial fishing has been established. Agreements in place with 70 fishermen will prevent negative impacts on their business and define clear rules for the period of construction.

Protection for divers | Offshore Wind at RWE

Protection for divers

An agreement on appropriate remedial measures ensures diver safety during the construction work. Additional partnership agreements have been put in place with charter boat owners.

Responsibility for the future

We take concerns and needs into consideration, and support the local fishing community and ports. Ongoing fishing operations within the wind farm are possible, and simultaneously bolster and encourage local job creation.
