Every summer, the same handful of scorching afternoons drive an outsized share of your utility's total costs — millions of air conditioners kicking on at once strains the grid and forces utilities toward their most expensive, least efficient backup power plants. To avoid building more of those plants just to cover a few peak hours a year, most major U.S. utilities now run demand response (DR) programs: they pay you, directly, to let them briefly cycle down your air conditioner or water heater during those specific windows. It's one of the few energy programs where the utility pays you rather than the other way around, and it's widely under-used simply because most homeowners have never heard of it.
How Demand Response Actually Works
The mechanism is simpler than it sounds. Your utility (or a third-party aggregator working on its behalf, like OhmConnect or Leap) either installs a small switch on your outdoor AC condenser or connects to your existing Wi-Fi smart thermostat. During a small number of "event" days each summer — typically triggered when grid demand is forecast to exceed available supply, almost always on the hottest weekday afternoons — your AC compressor is cycled off for a portion of each hour, commonly 15-20 minutes out of every 60, instead of running continuously. The indoor fan usually keeps circulating air the whole time, so most participants report the temperature drifting only 1-3°F higher during an event rather than the AC shutting off completely.
Events are usually capped at a modest number of hours per season (often 30-60 hours total across the whole summer), and most programs let you override a limited number of events per year — by app, text, or a physical button — without losing your enrollment or annual payment. You stay connected to the grid the entire time; nothing resembles a rolling blackout. The tradeoff is a few degrees of extra warmth during a handful of afternoons, in exchange for an annual payment.
How Much Can You Actually Earn
Payouts vary by utility and program type, but most residential AC-cycling and thermostat-based programs land in a fairly predictable range:
- Basic AC-cycling or smart thermostat programs: typically $25-$100 per year as a flat seasonal bill credit or rebate, paid automatically once you've enrolled a qualifying device.
- Higher-tier residential programs: some utilities, including Southern California Edison's Save Power Day program, pay up to $160 in summer bill credits for central AC customers who enroll and accept automatic cycling.
- Battery storage or EV charger enrollment: programs that let a utility draw on your home battery or delay your EV charging during peak hours can pay considerably more than AC-only programs, often several hundred dollars a year, because a battery or EV charger gives the utility more precisely controllable capacity than a single compressor switch.
These are meaningfully smaller numbers than the battery-focused virtual power plant programs some utilities advertise, which can pay $500+ a year — but AC-cycling and thermostat programs require no hardware purchase at all beyond, in some cases, a smart thermostat you may already own. That makes the effective return very high relative to the (near-zero) cost of enrolling.
Two Types of Programs: Direct Load Control vs. Smart Thermostat (BYOT)
Older direct load control programs use a small switch physically installed on your outdoor AC unit by a utility technician, usually at no cost to you. They're simple, work with any central AC system regardless of age, and don't require a smart thermostat, but they offer the utility only a blunt on/off toggle.
Newer "bring your own thermostat" (BYOT) programs work entirely through your existing Wi-Fi-connected smart thermostat's app — see our smart thermostat vs. programmable thermostat comparison if you're deciding whether to upgrade. Because a smart thermostat can adjust your setpoint by precise increments rather than cutting power entirely, these programs often deliver a gentler in-home experience and frequently pay a modest bonus on top of the standard enrollment credit. If you already own a smart thermostat, checking whether your utility offers a BYOT program is usually the highest-value first step, since you're not installing anything new — you're just opting an existing device into a program it's often already compatible with.
Is It Worth the Comfort Tradeoff?
For most households, yes, with a caveat. The payment is modest — closer to "found money for doing nothing" than a meaningful dent in your annual electric bill — but the actual cost to you is genuinely small for most participants: a few degrees of extra warmth on a handful of already-hot afternoons, with an override option if a specific event is inconvenient (hosting guests, working from home during a heat-sensitive task, a household member with heat sensitivity). The households where it's less worth it: anyone with a health condition that makes even brief indoor temperature swings risky, or a household that would need to override every single event, since chronic overriding can reduce or eliminate the payment and, in repeated cases, can result in automatic disenrollment.
Households already tracking and reducing summer AC costs (see our electric bill spike calculator and AC running cost calculator) are a natural fit for these programs, since the same households that are already cost-conscious about cooling tend to tolerate a few degrees of variation without much friction.
How to Find Your Utility's Program
Coverage and program names vary significantly by region and utility, so there's no single national enrollment page. The most reliable path: search "[your utility name] demand response" or "[your utility name] AC cycling program," or check the "ways to save" or "rebates" section of your utility's website directly — nearly every major investor-owned utility runs some version of this, and many municipal and cooperative utilities do too. If your utility partners with a third-party aggregator like OhmConnect or Leap rather than running its own program, enrollment usually happens through the aggregator's app instead of the utility's site. Programs typically open for enrollment in spring and run through the end of the cooling season (commonly June through September), so if you're reading this mid-summer, check whether late enrollment is still open — some programs accept it throughout the season.
