ATCO is buying the Adelaide Wind Farm near Strathroy from Suncor as part of a $713-million deal with Suncor that features wind farms in Alberta.
The Adelaide-Metcalfe wind farm has been operating since 2015, has 18 turbines, a meteorological tower and an electrical collection system and a substation.
It is partly owned by Aamjiwnaang First Nation.
Suncor said it sold to invest more money in hydrogen and renewable fuels.
