Total has agreed to buy 80% of the 96 megawatt Erebus floating wind project off Wales.
The French energy giant inked the deal with developer Simply Blue Energy.
It marks Total’s entry into the offshore floating wind market.
The company said floating wind was set for “strong growth” in the years to come.
This emerging technology has wide potential, opening access to sites further offshore, which have less impact on the landscape, and benefit from very high wind resources, Total said.
Executive Patrick Pouyanne said: “With its entry into floating offshore wind, Total confirms its ambition to contribute to the development of renewable energy worldwide.
“Floating offshore wind is an extremely promising and technical segment where Total brings its extensive expertise in offshore operations and maintenance.
“Total has the appropriate skills to meet the technological and financial requirements that determine the success of future floating offshore developments.”
