On the hottest days of summer, when every air conditioner in Texas runs full blast and the ERCOT grid approaches its limit, your electricity provider might ask you to use less power for a few hours. In exchange, they’ll pay you.
That’s demand response in a nutshell. It’s a growing part of how Texas manages its electricity grid, and it puts money in your pocket for something that’s usually just a minor inconvenience.
What Is Demand Response?
Building a power plant that only runs 100 hours per year is wildly expensive. Demand response (DR) flips the script: instead of adding generation, the grid operator pays consumers to temporarily use less during periods of high stress.
How It Works for Homeowners
- You enroll in a demand response program through your electricity provider or a third-party aggregator
- When the grid is under stress (typically hot summer afternoons), you receive a notification
- You reduce your electricity usage for a set period (usually 2-4 hours)
- You receive compensation: bill credits, lower rates, or direct payments
The most common residential DR programs work through smart thermostats. You give the program permission to raise your thermostat setting by 2-4 degrees during peak events. In exchange, you get paid.
Who Runs These Programs?
Demand response in Texas operates at multiple levels:
ERCOT: The grid operator coordinates large-scale demand response through programs like Emergency Response Service (ERS) and the 4 Coincident Peak (4CP) program for commercial customers.
Retail providers: Companies like TXU Energy and Reliant Energy offer residential DR programs, usually tied to smart thermostat enrollment.
Third-party aggregators: Companies like OhmConnect, Voltus, and EnergyHub aggregate thousands of individual households into virtual power plants and participate in ERCOT’s wholesale market programs.
Types of Residential Demand Response
Three program types exist for Texas homeowners, each with different trade-offs between effort and payout.
Smart Thermostat Programs
The most common residential program. You connect your smart thermostat (Nest, Ecobee, Honeywell) to the program, and during peak events, the thermostat automatically adjusts your temperature up by 2-4 degrees.
What you feel: Your house gets slightly warmer for 2-4 hours on maybe 10-20 days per summer. Most people barely notice. The thermostat adjusts gradually, not all at once.
What you get: $25-75 per summer season in bill credits, depending on the program and your home’s AC capacity.
You can opt out: Most programs let you override individual events. If it’s your kid’s birthday party and you need the AC blasting, you can skip that event. Too many opt-outs, and you forfeit the seasonal payment.
Peak Time Rebates
Instead of automated thermostat control, some programs simply pay you a higher rate for every kWh you don’t use during peak events compared to your baseline.
How it works: Your provider establishes a baseline for your typical usage on a hot afternoon. During a peak event, any kWh you use below that baseline earns you a rebate.
Example: Your baseline is 5 kWh per hour during peak. During an event, you use 3 kWh per hour. You get paid for the 2 kWh reduction at a premium rate (sometimes $1-2 per kWh saved).
The advantage: No device control. You decide how to reduce—raise the thermostat, turn off the pool pump, postpone laundry. It’s entirely in your hands.
Behavioral Programs
The simplest version: your provider sends you a notification asking you to conserve, tracks whether you did, and rewards you with small credits or prizes.
No device enrollment. No automated control. Just a text message saying “the grid needs help, please reduce usage between 3-7 PM” and a $5 credit if you measurably reduced consumption.
These programs pay the least but require the least commitment.
What Demand Response Actually Pays
$50-75 per year. That’s the realistic range for most Texas homeowners in a demand response program. Not life-changing, but here’s the full breakdown.
Typical Residential Earnings
| Program Type | Annual Payment | Commitment Level |
|---|---|---|
| Smart thermostat program | $25-75/year | Low (automated) |
| Peak time rebates | $30-100/year | Medium (manual reduction) |
| Behavioral programs | $10-30/year | Very low (voluntary) |
| Third-party aggregator | $50-150/year | Medium (device enrollment) |
The highest-paying residential programs come from third-party aggregators who participate in ERCOT wholesale markets. By combining thousands of homes, they can bid into demand response auctions and pass a portion of the revenue to participants.
What It Works Out To
For most Texas homeowners enrolled in a smart thermostat DR program:
- 10-20 peak events per summer
- 2-4 hours each event
- Thermostat raised 2-4°F during events
- Annual compensation: $50-75
That’s roughly $3-5 per event. Not life-changing, but it’s free money for a barely noticeable temperature difference on days when it’s 107°F outside and your house was going to be warm regardless.
How to Enroll
Most Texans can sign up for demand response in under 15 minutes. You have three paths.
Through Your Electricity Provider
Check your provider’s website or call customer service to ask about demand response programs. TXU Energy and Reliant Energy both offer smart thermostat enrollment programs.
Requirements:
- Smart thermostat (Nest, Ecobee, or compatible model)
- Wi-Fi connection
- Central air conditioning
- Provider account in good standing
Some providers offer a free or discounted smart thermostat as an enrollment incentive. Check if the thermostat deal is better than buying one separately—sometimes it is, sometimes the bundled rate premium wipes out the savings. See our guide on bundled electricity plans for the math on evaluating these deals.
Through a Third-Party Aggregator
Companies like OhmConnect, Virtual Peaker, or EnergyHub run their own demand response programs that work alongside (not instead of) your electricity plan.
You enroll separately, connect your smart thermostat, and participate in events they coordinate. Payments come directly from the aggregator, independent of your electricity bill.
The advantage: you can stack aggregator payments on top of any provider-sponsored DR program, though check both programs’ terms to make sure they allow it.
ERCOT’s 4CP Program (Commercial)
This is primarily for commercial and industrial customers, but some residential aggregators incorporate 4CP awareness into their programs.
ERCOT determines the four highest-demand 15-minute intervals each summer (one per month, June through September). Large consumers who reduce usage during these peaks save significantly on their transmission charges for the following year.
Residential customers don’t participate directly, but aggregators who predict and respond to 4CP peaks pass some savings to their enrolled households.
The Grid Perspective: Why This Matters
Your $50 credit is a rounding error. But 500,000 thermostats adjusting simultaneously? That’s a virtual power plant — and it’s a real reason Texas has avoided blackouts on several peak demand days.
The Peak Problem
Texas electricity demand peaks on hot summer afternoons when every AC unit runs at full capacity. The grid must have enough generation to meet that peak demand—but building power plants that only run 100 hours per year is incredibly expensive.
Demand response reduces peak demand by 1-3%, which can be the difference between a stable grid and rolling blackouts. During near-emergency conditions, ERCOT can activate demand response resources to avoid curtailing power to anyone.
Growing Importance
As Texas adds more solar power, the grid faces a new challenge: solar production drops off in the evening just as people come home and crank up the AC. This creates a steep ramp in demand between 5-8 PM that’s difficult for other generators to fill.
Demand response during these evening ramp hours will become increasingly important—and likely increasingly valuable for participants.
Is Demand Response Worth It?
The short answer: if you already own a smart thermostat, yes. The effort rounds to zero. If you don’t own one, it depends on whether you planned to buy one anyway.
The Case For Signing Up
It’s mostly automated: Smart thermostat programs require zero ongoing attention. You enroll once, and the thermostat handles everything.
The comfort impact is small: A 2-4°F increase during the hottest hours of the hottest days is barely noticeable, especially with ceiling fans running. Your house goes from 74°F to 77°F, not from 74°F to 85°F.
You can opt out: Having a bad day? Override the event. Most programs allow several opt-outs per season without penalty.
Free money for not much: $50-75 per year for doing almost nothing. Over 10 years, that’s $500-750 in credits.
Grid contribution: You’re helping prevent blackouts. That has real value for your community, even if the personal payment is modest.
The Case Against
Small payments: $50-75 per year isn’t meaningful for many households. If the enrollment process or occasional opt-out hassle isn’t worth the payout, skip it.
Privacy concerns: Connecting your thermostat to a utility or third-party aggregator means sharing your home’s energy usage data and giving them limited control of your AC. If that’s a dealbreaker, behavioral programs (text-based, no device control) are a lower-commitment alternative.
Not for everyone: If you have medical conditions requiring consistent temperatures, or if household members can’t tolerate heat, demand response isn’t appropriate. Programs allow medical exemptions for this reason.
The Bottom Line
Demand response programs in Texas are low-risk, low-reward. You give up a few degrees of comfort on the hottest days of summer, and you get paid $50-75 per year for it. The enrollment is easy, the events are automated, and you can opt out when you need to.
Is it worth it? For most homeowners with a smart thermostat, yes. The effort-to-reward ratio is high because there’s almost no effort. You sign up, connect your thermostat, and cash the credits.
If you don’t have a smart thermostat, the calculation changes. Buying a $130 thermostat to earn $75 per year takes nearly two years to break even. But if you were already considering one for comfort and efficiency, the DR payments sweeten the deal.

Frequently Asked Questions
What is demand response in Texas electricity?
Demand response is a system where homeowners voluntarily reduce electricity usage during peak grid stress in exchange for payment. Most residential programs work through smart thermostats that automatically raise your temperature 2-4 degrees during peak events (typically hot summer afternoons). You receive bill credits or direct payments for participating.
How much do demand response programs pay in Texas?
Residential demand response programs typically pay $25-150 per year depending on the program type. Smart thermostat programs pay $25-75 per summer season. Third-party aggregators pay $50-150 per year. The payments are modest but require minimal effort.
Can I opt out of demand response events?
Yes. Most programs allow you to override individual events through your thermostat or the program’s app. If you skip too many events, you may forfeit part of your seasonal payment, but you won’t be penalized otherwise. Programs are voluntary and can be canceled at any time.
Do I need a smart thermostat for demand response?
For automated programs, yes—you need a compatible smart thermostat (Nest, Ecobee, Honeywell, or similar). Behavioral programs that send text notifications and track your response don’t require any special equipment. Some providers offer free or discounted thermostats as enrollment incentives.
