Construction of the UK’s giant Triton Knoll offshore wind farm has reached the half-way mark, with contactor DEME having installed Vestas V164-9.5MW turbine number 45 this week.

The 857MW project, being developed off the Lincolnshire coast in the North Sea by German utility RWE and its Japanese consortium partners J-Power and Kansai Electric Power, will supply electricity to 800,000 households in Britain, once fully online.

“A picture is worth a thousand words; this one expresses both the challenge and beauty of offshore work,” said Vestas in a post on LinkedIn.

Triton Knoll will be the largest run offshore wind project operated by RWE, which is also developing the 1.4GW Sofia, aims to expand its global offshore wind portfolio toward the target of 13GW via €5bn ($6bn) in investment between 2020-22.

The developer successfully bid for two new sites adjacent to Sofia on Dogger Bank, totalling 3GW of capacity, in the UK Crown Estate’s recent Round 4 leasing auction

UK seabed landlord the Crown Estate in February awarded six project leases representing almost 8GW of capacity for wind farms designed to help propel the country to its target of 40GW of offshore wind in place by 2030, four times the current total.
