The JV, dubbed Skylark, intends to build 350MW of new green energy projects into the UK planning system in the first five years.

The projects, which would represent a potential investment of £500m, will deliver enough energy for about 200,000 homes.

Three development sites have already been identified for the first 100MW round and Skylark plans to start electricity generation by 2018.

Ecotricity founder Dale Vince said: "Ecotricity will use its expertise in green energy development to design wind parks and gain planning consents, while Skanska will use their expertise in construction to build them.

"It’s a simple partnership that will help to bring energy independence to Britain using green energy made in Britain."

Skanska Infrastructure Development EVP Steve Cooper said: "At Skanska, sustainability is at the heart of everything we do. Wherever we work, we strive to push forward the green agenda in construction and infrastructure development. Our green agenda, together with our wish to build what society needs, help to define us as a company."

Ecotricity and Skanska claim the new JV would help reinvigorate the UK’s onshore wind sector, which has faced uncertainty over various factors.

Earlier in 2014, UK Prime Minister David Cameron’s Conservative Party has unveiled plans to end government subsidies for onshore wind projects if it wins the 2015 general election.
