⚠️ Program details change frequently. Qualifying thermostat lists and credit amounts are updated by utilities periodically. Verify with your specific utility before enrolling.

Many utilities, including those in Ontario, the Northeast US, and parts of the Midwest, pay ongoing bill credits when you enroll a qualifying smart thermostat in their demand-response (peak-saver) program. The credits are automatic, passive, and require no ongoing action after enrollment.

Whether your thermostat qualifies depends on the specific program and which models are on their approved list.

What a Peak Saver / Demand Response Credit Is

During peak demand periods (hot summer afternoons when electricity use spikes), utilities struggle to meet demand without buying expensive emergency power. They manage this by enrolling smart thermostats to reduce cooling setpoints by 2–4°F for the length of an event, typically 10–20 times per summer, each lasting 2–4 hours.

You receive ongoing bill credits for staying enrolled. You can override any event at any time. Your comfort is protected by opt-out controls.

The financial structure:
– Enrollment credit: A one-time payment ($25–$100) when you first register your thermostat
– Annual / seasonal credit: An ongoing payment ($20–$100/year or season) for staying enrolled and participating
– Instant discount: Some programs reduce the purchase price of a qualifying thermostat at participating retailers

Which Thermostats Qualify

Most peak-saver programs require a thermostat that:
1. Has Wi-Fi connectivity and cloud integration with the utility’s platform
2. Is on the utility’s approved device list
3. Controls a central cooling system (central AC or heat pump); most programs don’t support window AC units or baseboard heaters

Consistently eligible across most programs:
– ecobee Premium / Enhanced (the most widely eligible across Canadian and US programs)
– Google Nest Learning Thermostat / Nest Thermostat (eligible through Rush Hour Rewards and many BYOT programs)
– Honeywell Home T9 / T10 / Sensi

Check your specific program for:
– Amazon Smart Thermostat (eligible in some programs, not all)
– Mysa V2 / Sinopé (PSE Flex in Washington is one of the few programs that explicitly includes line-voltage baseboard thermostats)

Ontario: Peak Demand Programs

In Ontario, peak-saver and demand-response programs have historically been run through utilities and the Independent Electricity System Operator (IESO).

Peaksaver PLUS (historical): Ontario utilities including Toronto Hydro, Alectra, and Hydro One have run peaksaver programs. These programs allowed utilities to cycle air conditioning compressors or adjust smart thermostat settings during peak events.

Current status: Ontario’s demand-response programs for residential smart thermostats have evolved. Contact your specific Ontario utility (Toronto Hydro, Alectra, Hydro One, etc.) to ask about current smart thermostat enrollment programs.

How to Check if Your Thermostat Qualifies

Step 1: Go to your utility’s website and search for “demand response,” “peak saver,” or “thermostat program.”

Step 2: Check the approved device list. Each program maintains its own, and your thermostat must be on the list to enroll.

Step 3: If your thermostat isn’t on the list, check whether your thermostat brand has a built-in utility program directory. Both ecobee (through eco+ in the app) and Nest (through the Nest app energy settings) show available programs for your location on their own.

Step 4: Enroll. This is usually done through your utility’s portal, your thermostat’s app, or both. Most programs take effect within 24–48 hours of enrollment.

How Enrollment Works in Practice

Once enrolled:
– Your utility sends a signal on event days, hot summer afternoons in most cases
– Your thermostat adjusts its cooling setpoint by 2–4°F on its own
– Events run 2–4 hours
– You can override at any time using the thermostat or app
– Credits accumulate and appear on your utility bill (monthly or seasonally)

The override shouldn’t cost you the credit for the entire season. Most programs allow a reasonable number of overrides without penalty. If you opt out of events on a regular basis, some programs may reduce your credit or disenroll you.

Buying a Thermostat to Qualify

If your current thermostat doesn’t qualify (or you don’t yet have a smart thermostat), buying a qualifying model to enroll makes financial sense in most active program areas.

The math:
– ecobee Enhanced: ~$229 CAD
– Less rebate: ~$75 ($154 net)
– Enrollment credit: ~$50
– Annual credit: ~$40–$60/year
– Plus energy savings from scheduling/geofencing

In many cases, the enrollment credit and first year of demand-response credits bring the net cost of the thermostat below $60. The thermostat then continues earning credits in subsequent years.

Frequently Asked Questions

What is a peak saver credit?
A bill credit your utility pays you for enrolling a qualifying smart thermostat in their demand-response program. The utility can adjust your thermostat for the length of an event during peak electricity demand periods; in exchange, you receive ongoing credits, typically $20–$100 per year or season.

Does my existing smart thermostat qualify?
Check your utility’s approved device list. ecobee, Nest, and Honeywell models are most consistently eligible. If your thermostat isn’t listed, you may need to upgrade to a qualifying model to participate.

Can I override the adjustments?
Yes. Every demand-response program allows manual overrides. You can push the temperature back to your preferred setting at any time. Frequent overrides may reduce your seasonal credit, but occasional overrides are unlikely to affect enrollment.

Is a peak saver program worth the loss of control?
For most participants, yes. Events are infrequent (10–20 per summer), brief (2–4 hours), and produce minor adjustments (2–4°F). In a well-insulated home, you may not notice them. The credits are passive income; enrollment requires no ongoing effort.

Do Canadian utilities offer peak saver programs?
Some do. Ontario utilities have historically run peaksaver programs. Hydro-Québec’s Hilo platform offers demand-response credits for enrolled Sinopé thermostats. Canadian programs are less widespread than US programs. Contact your utility directly for current availability.

Can I combine a purchase rebate with demand-response enrollment?
Yes, in most cases; they’re separate programs. You claim the purchase rebate from your utility for buying the thermostat, then enroll in demand-response as a separate step to earn ongoing credits. Most programs don’t prohibit stacking these benefits.
