One Hundred million kWhs of energy savings achieved through Hydro One's Conservation and Demand Management program

May 4, 2007 — In Hydro One's recently released Conservation and Demand Management (CDM) Report, the company announced it achieved substantial results since the program's inception in 2005. Through a range of CDM initiatives, energy savings of 100 million kWhs, or roughly the electricity consumed in a community the size of Gravenhurst in a year, were realized.

To date, approximately 880,000 people have participated in one or more of Hydro One's 20 CDM initiatives and programs. This participation has resulted in the expected electricity savings over the lifetime of installed energy efficient equipment of 635 million kWhs, or annual consumption of over 53,000 homes. In addition to energy savings, the demand for electricity during peak periods has been reduced by almost 11MW or the average peak demand of almost 4,000 homes. Hydro One's CDM program provides a range of incentives to help customers save electricity and money, and ease strain on the provincial electricity grid during peak demand periods.

"Our CDM programs have allowed us to work in partnership with our customers to promote a conservation culture in Ontario and at the same time help our customers reduce their electricity costs," said Laura Formusa President and CEO, Hydro One (Acting). "We established a suite of programs that responds to our broad and diverse customer base and at the same time achieves measurable results."

"The results of Hydro One's CDM program represent a tremendous achievement in energy savings in a relatively short period of time," said Ontario Energy Minister Dwight Duncan. "The popularity of Hydro One's CDM program is proof positive that we are making significant headway in establishing a more energy conscious and energy efficient Ontario."

In 2005, the company piloted projects in all customer sectors including residential, farm, commercial, industrial, municipalities, schools and hospitals to evaluate customer acceptance and effectiveness of new CDM technologies. In 2006, larger scale programs were rolled out in selected locations across the province. These included equipment that measure residential electricity use and associated cost in real time, smart thermostats that remotely control central air conditioning, pickup of old low efficiency appliances (e.g. air conditioners and refrigerators), incentives for social housing energy efficiency improvements, building energy audits, and the first phase of smart meters. This year many of these programs will be expanded and made available to all Hydro One customers.
