Pension fund manager Caisse de depot et placement du Quebec has invested about $500 million US in wind farms in the United States and Canada owned by Invenergy Wind.

Chicago-based Invenergy said Tuesday that the portfolio of 11 operating wind farms in the United States and two in Canada have a combined output of about 1,500 megawatts.

One of the Canadian operations is the Le Plateau wind farm in Quebec's Gaspe region.

It has been in commercial operation since early 2012 and sells all of its renewable energy to Hydro-Quebec under a long-term contract.

Invenergy said it remains the majority controlling shareholder following the transaction.

Invenergy and its affiliated companies develop, own and operate large-scale renewable and other clean energy generation facilities in North America and Europe.
