Renewable energy firm RWE Innogy has formed a 50:50 joint partnership with Norwegian Statkraft for setting up 900MW Triton Knoll offshore wind farm in UK.
Projected to supply enough electricity for around 800,000 average UK households, the wind facility will involve an investment of £3bn to £4bn ($4.6bn-$6.1bn).
The firms have not revealed the financial details about the agreement, which is expected to close by 2017.
The partners are likely to start construction of the wind project by the same year.
Located off the east coast of the country, the wind farm development will offer around 1,900 jobs.
The partners will handle the development and construction phases for the project through a joint team.
