The 50 MW project in Ontario was developed and sold by First Solar Inc and commenced commercial operations earlier this year. Alterra will be the managing partner for the facility, and will hold a 10% interest.

"With this transaction, Alterra has added solar power to its operating portfolio, opening the door for us to pursue other solar opportunities as well as continued growth in wind, hydro and geothermal power,” said Alterra CEO, John Carson.
