CALGARY, ALBERTA -- (MARKET WIRE) -- 06/16/09 -- Canada's largest and most diversified renewable energy company, Canadian Hydro Developers, Inc. (TSX: KHD), was named one of Canada's top 50 most socially responsible corporations by Jantzi Research Inc., an independent investment research firm, and Maclean's Magazine.

"We are extremely pleased to be recognized in this manner," says Kent Brown, Executive Vice President & Chief Financial Officer. "Our business has always been rooted in optimizing the social,
environmental, and economic benefits of low-impact, renewable energy generation facilities."

Jantzi Research in Toronto compiles detailed reports on thousands of stocks in Canada and around the world, delving into environmental, social and governance performance. The firm's research serves as the cornerstone for some of the largest socially responsible investment funds in Canada.

"Climate change and energy are key issues of corporate social responsibility, and Canadian Hydro Developers has made itself part of the solution by becoming a leader in Canada in the sustainable development of renewable energy sources," says Kevin Ranney, Managing Partner/Director of Research for Jantzi Research.

Canadian Hydro is about to fully commission its $475 million Wolfe Island Wind Project at the end of June, which will be the second largest of its kind in Canada. Once completed, the 197.8 MW project is expected to generate approximately 594 GWh of renewable power annually. Combined with the company's Melancthon EcoPower(R) Centre, Canadian Hydro will double its operations.

In making the list, Canadian Hydro was selected on the basis of its performance across a broad range of environmental, social and governance indicators. Jantzi Research conducted a thorough examination of the company's profile and corporate governance structure, researched media sources, online databases, government sources and NGOs, as well as consulted with key stakeholders.

"Being named among Canada's top 50 most socially responsible corporations confirms that we're well positioned to provide effective leadership and vision for Canadian Hydro to grow value responsibly, in a profitable and sustainable manner," says Brown.
