TORONTO - Hydro One is proud to support Earth Hour again this year and is encouraging its customers and employees to reduce their energy consumption on Saturday, March 28, 2009 between 8:30 and 9:30 p.m. "Hydro One is proud to participate in this important WWF and global initiative by reducing lighting at our head office and locations across the province and by encouraging our employees and customers to participate in Earth Hour," said Giuliana Rossini, Director, Strategy and Conservation Officer, Hydro One. "Although many lights at our field locations must remain on for the safety of the public and our workers, we are taking steps to reduce electricity use wherever possible."

Hydro One is celebrating Earth Hour every day by taking steps to reduce its overall energy consumption. Last year, it conducted energy audits and retrofits at three of its facilities in Ontario with five more building retrofits planned for this year. Energy retrofits are expected to reduce CO2 air emissions by 400 tonnes annually, representing a savings of more than 600,000 kWh per year.

The Company is also taking steps to minimize the impact of its fleet by purchasing hybrid vehicles for at least 10 per cent of new light duty vehicle purchases, installing speed limiters on heavy-duty vehicles and educating employees on anti-idling and proper tire inflation. Hydro One expects these campaigns will reduce green house gases by 400,000 kg each year. Hydro One customers care about conserving electricity too. Since 2005, they have saved more than 400 million kWh of electricity, a savings of more than 260,000 tonnes of CO2 emissions, through conservation and demand management programs.
