Ontario’s electricity system operator is planning to roll out a voluntary program that pays customers with smart thermostats to have their air conditioning remotely reduced on hot summer days.
Energy Minister Todd Smith had asked the Independent Electricity System Operator (IESO) to suggest new conservation initiatives, as the province seeks to manage rising demand from electrification, The Canadian Press reports. On Tuesday, he announced he had accepted its recommendations and will introduce new and expanded programs starting next year, with a cost of C$342 million.
One of the programs will let households with central air conditioning and a smart thermostat volunteer to allow the IESO to lessen their cooling load in order to reduce peak demand on certain summer days, and get paid an as-yet unspecified incentive.
“This expansion will help deliver enough annual electricity savings to power about 130,000 homes every year, and reduce costs for consumers by over $650 million,” Smith told a news conference. “It’s a win for customers, it’s a win for climate, and a win for Ontario.”
The IESO estimates there are 600,000 smart thermostats in the provinces, nearly three-quarters of them in single-family homes, based on discussions with manufacturers, a spokesperson told The Energy Mix in an email. From experience in other North American jurisdictions, the program is expected reach 15% of those households in the first year.
The government said that over a lifespan of up to 20 years, the programs will result in three million tonnes of greenhouse gas emission reductions, CP writes.
The programs also include support for greenhouses in southwest Ontario—such as incentives to install LED lighting, solar generation, or battery storage—as well as enhancements to the Save On Energy Retrofit Program for businesses, institutions, and municipalities.
“Whether it’s funding for municipalities to upgrade the chillers at their local rinks or arenas, funding for a hospital to make HVAC or air handling system upgrades, or funding for a local business for building upgrades like new insulation or better windows and doors,” Smith said, “all these upgrades would not only reduce demand on the provincial grid, but also reduce energy use and operational costs.”
Ontario’s opposition parties said the programs announced Tuesday don’t even replace a number of energy conservation programs previously cut by the Progressive Conservative government, such as an incentive to buy energy-efficient heating and cooling equipment and energy efficiency incentives for new buildings.
“This program is woefully inadequate to address the climate crisis and the electricity shortage Ontario faces,” said Green Party Leader Mike Schreiner.
“A small incentive targeting a select group of homeowners, disguised as an energy efficiency program, fails to make up for the efficiency programs (Premier Doug) Ford cancelled four years ago.”
In recent months, the IESO has been planning new conservation initiatives as well as looking to procure new, much of it high-emitting electricity generation while it looked to fill an upcoming electricity supply gap, with Pickering Nuclear Generating Station set to shut down and demand rising.
But Smith said last week that the province plans to run Pickering for an extra year, to 2026, and possibly refurbish it to operate for another 30 years as “unprecedented growth” in areas such as electric vehicle manufacturing means demand could increase even more quickly than previously anticipated. That was in spite of a blockbuster consulting report, released just last week, showing that distributed energy resources could supply the entire shortfall with the right policy supports.
The IESO says conservation is a cost-effective and environmentally friendly way to mitigate demand.
Critics of the Progressive Conservative government say the province would not be in as much of a supply crunch now if it hadn’t cancelled 758 green energy contracts during Ford’s first term.
