Renewables group Pattern Energy boosted its operating portfolio to 4.4GW after acquiring 251MW across two North American wind farms.

Pattern – which buys projects taken into operation by its sister companies at Pattern Development – spent $293m to buy half-shares in the 300MW Henvey Inlet project in Ontario, and the 220MW Grady Wind in New Mexico.

Pattern said both “are backed by long-term power contracts with investment-grade offtakers”.

"These acquisitions increase our portfolio by 13% to 4.4GW of operational capacity across 28 renewable energy facilities," said Mike Garland, CEO of Pattern Energy.
