RWE shrinks Triton Knoll capacity

German utility RWE will cut the capacity of its Triton Knoll offshore wind farm by up to half, saying the project off Eastern England will now come in between 600MW and 900MW.

The group’s RWE npower renewables unit said the revised capacity range follows a review at Triton Knoll, which received UK government offshore consent for 1.2GW last July, and will "ensure the efficiency and utilisation of the site is maximised".

Project Manager Jacob Hain said: “The recent optimisation work is part of a project review to make the site more competitive and more economic in line with government proposals to bring down the cost of offshore wind.”

The North Sea project has also undergone further design work for its onshore infrastructure, which will now occupy a footprint more than 50% smaller for its substation and 40% for its intermediate electrical compound, RWE said.

The onshore element of Triton Knoll has been the subject of vocal opposition from local politicians in Lincolnshire, including the area’s Member of Parliament.

RWE said work is ongoing on proposed electrical infrastructure. “Local communities will have the opportunity to take part in a formal consultation which will take place before any planning application is submitted.”

The Triton Knoll changes are the latest in a string of revisions to plans for the UK’s offshore wind pipeline since the government announced final details of its new support regime late last year.

One of the most significant of those changes was RWE’s decision to abandon plans to develop the 1.2GW Atlantic Array zone off southwest England.
