Thank you for helping to keep Ontario’s electricity reliable.

The peaksaver PLUS® program endED on December 31, 2017.


After 10 successful years, the peaksaver PLUS® program ended December 31, 2017. Together with more than 315,000 participating homes and businesses across the province, you have played an important part in protecting the environment while keeping Ontario’s electricity reliable.


When you first signed up, a thermostat or electronic switch was installed to temporarily reduce the electricity used by your air conditioner, electric water heater or pool pump, on the hottest summer days when electricity demand was highest. With significant changes in smart thermostat technology and the evolution in demand response programs, peaksaver PLUS® ended on December 31, 2017 .

Effective December 31, 2017, the peaksaver PLUS® program including maintenance services for peaksaver customers enrolled prior to 2011 and peaksaver PLUS® customers will end as a result of a public stakeholder engagement that was completed by the Independent Electricity System Operator (IESO) April 2016. Participating peaksaver PLUS® customers will not be included in any peak electricity load control events between May to September.
