The new joint venture company, Skylark, will construct wind farm projects in UK while leveraging Ecotricity’s experience in developing green energy projects through planning as well as Skanska’s experience in construction and engineering.

In first five years, Skylark will launch new green energy projects, with total generation capacity of 350MW, into planning system representing a potential investment of £500m if the projects are approved.

The projects are expected to supply green electricity to 200,000 homes.

For the Skylark’s first round of investment, representing around 100MW of generating capacity, three development sites have been identified already.

The new company intends to deliver new renewable energy capacity in the region as early as 2018 while creating a range of new jobs.

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.

"This joint venture with Skanska will help Ecotricity further advance the mission we already pursue with the support of our customers – changing the way energy is made in Britain so we can all live more sustainable lives."

Skanska Infrastructure Development executive vice president Steve Cooper said: "Our green agenda, together with our wish to build what society needs, help to define us as a company."
