Gregor Alexander, SSE's finance director, said: "The sale of a stake in Dogger Bank Wind Farm to Eni is another successful example of SSE's approach to partnering to create and secure value for shareholders.
"This transaction will enable us to fund further low carbon growth opportunities, helping to deliver governments' net zero ambitions and our own target to treble our renewable output by 2030."
SSE is also the 49% shareholder in the Seagreen offshore development project in Scotland and wholly owns the Viking windfarm project on the Shetland Islands.
