PGGM and Ampère Equity Fund will pay around £16 million for their share in the offshore wind farm, in addition to a pro rata share of the construction costs.

DONG Energy will retain a 50.1% stake in Walney Offshore Wind Farm and SSE will retain the 25.1% stake it acquired from DONG Energy in December 2009.

DONG Energy will be the leading partner in the remaining construction works related to the offshore wind farm, and has assumed certain specific obligations towards PGGM and Ampère Equity Fund relating to the final construction cost of the project and its completion.

Excluding the connection to the Great Britain electricity network, the cost of constructing Walney is expected to total approximately £1 billion.
