Clean energy developer RWE has cleared Aker Solutions and Siemens Energy to proceed with work for the Norfolk Vanguard West and East wind farms in the U.K. North Sea, according to a Jan. 15 news release.

The wind farms are part of the first phase of RWE’s Norfolk Offshore Wind Zone, which is expected to produce enough renewable electricity to power more than 4 million homes. The wind zone will be comprised of three projects— Norfolk Vanguard West, Norfolk Vanguard East and Boreas—each with a capacity of 1.4 gigawatts, according to Germany-based RWE.

Aker Solutions will carry out engineering, procurement, construction and installation of the high voltage direct current offshore platform, the company said in a news release. Siemens Energy is responsible for the onshore station and high voltage equipment in the offshore substations. The Aker Solutions and Drydocks World joint venture will deliver the two HVDC platforms in 2027 with installation scheduled for 2028.

Project execution is already underway with engineering and procurement activities ongoing for both platform topsides and substructures, according to the release.
