Brookfield said late on Thursday that shareholders have tendered 59.7% of Western's common shares in response to its C$2.60 per share offer, at a cost to Brookfield of about C$92 million (US$90 million).
Together with Brookfield's existing holdings, the fund will now own 66.1% of the company. It is designed to strengthen Brookfield's presence in the California market.
"This will increase our operating wind capacity in the attractive California market by 56% to nearly 430MW, while the company's other operating and development stage assets are expected to create further value over time," says Brookfield CEO Richard Legault.
Brookfield has extended it offer to 7 March to allow more Western Wind shareholders to tender their shares.
