SSE PLC said Tuesday that it has agreed to sell its 25.1% stake in the Walney wind farm, offshore U.K., to Greencoat UK Wind PLC for 350 million pounds ($467.9 million)

The FTSE 100 energy company said the deal is part of a program to sell non-core assets with the intention of generating GBP2 billion by the fall of 2021. Walney--which is operated by 50.1%-owner Oersted AS--falls into that category, SSE said.

SSE said this program will support its GBP7.5 billion five-year capital expenditure plans to invest in core strategic assets as part of its transition to net zero emissions.

Greencoat UK Wind, a London-listed renewable infrastructure fund, separately said Walney is a natural addition to its portfolio of operating U.K. wind farms and increases its net generating capacity to over 1 gigawatt for the first time.
