ED3 Peak Rewards & Rebates 2026: Every Discount Available to Maricopa Homeowners
ED3 is a small utility — 36,000 meters vs APS's 1.3 million — but they offer a surprisingly deep list of rebate programs that most Maricopa homeowners don't know about. This guide covers every residential rebate and incentive ED3 has available in 2026.
ED3 Peak Rewards: $50/Year for Doing Almost Nothing
Peak Rewards is ED3's demand response program. You sign up, connect a compatible smart thermostat, and ED3 adjusts your AC setpoint by 2-3°F during peak demand events. In exchange, you get paid.
Peak Rewards at a Glance
How It Actually Feels
During a Peak Rewards event, your thermostat bumps from (for example) 76°F to 78-79°F for a few hours during the hottest part of the day. Most people barely notice a 2-3°F change if the house was pre-cooled. If it's genuinely uncomfortable, you can override the adjustment on your thermostat — you don't get penalized, though frequent overrides may affect your participation incentive.
Compatible Thermostats
ED3 Peak Rewards works with most major smart thermostats:
- Google Nest (all models)
- ecobee — ecobee3, ecobee3 lite, ecobee4, ecobee Smart, Enhanced, Premium
- Honeywell — T5, T6, T9, T10, RTH9, Vision Pro 8000/9000, RedLINK Gateway
- Sensi — Sensi, Sensi Lite, Sensi Touch 2
If you don't have a smart thermostat yet, the $100 rebate covers most of the cost of a Nest or Sensi. An ecobee Premium runs ~$220, so you'd pay ~$120 out of pocket. See our best smart thermostat for Arizona TOU rates guide for specific models ranked by TOU scheduling features.

The Best ED3 Rebate Stacking Strategy
Here's how to maximize your rebate value if you're a new Maricopa homeowner or planning upgrades:
- Smart thermostat + Peak Rewards — $100 thermostat rebate + $25 enrollment + $25/year. Do this first — it's free money for a device you want anyway.
- Solar shade screens — Cheap, immediate impact on cooling bills. Every south and west-facing window should have them in Maricopa.
- HVAC upgrade — If your system is 10+ years old, the ED3 HVAC rebate stacks with the federal 25C heat pump tax credit ($2,000). Time this for fall/winter when contractors are less busy.
- EV charger — If you drive an EV, the charger rebate + on-bill funding + the ED3 EV TOU rate ($0.056/kWh overnight) is a powerful combo.
- Pool pump — Variable speed pool pumps use 70-80% less energy than single-speed. The rebate + energy savings usually pay back in 1-2 summers.
ED3 vs APS: How Do the Rebate Programs Compare?
| Program | ED3 | APS |
|---|---|---|
| Demand response | Peak Rewards ($50/yr + thermostat) | Cool Reward ($150-500/yr + $3,750 battery) |
| Battery rebate | None | $3,750 |
| HVAC rebate | Yes (amount varies) | Cool Cash up to $2,000 |
| EV charger rebate | Yes + on-bill funding | None |
| Pool pump rebate | Yes | Yes |
| Shade tree rebate | Yes | No |
| Induction cooktop | Yes | No |
ED3 wins on breadth — more rebate categories (shade trees, induction cooktops, EV charger on-bill funding) than APS. APS wins on battery/VPP — the $3,750 Cool Reward rebate and $500/year VPP earnings dwarf anything ED3 offers. For the full comparison, see our ED3 vs APS rates guide.

How does ED3 Peak Rewards compare to APS demand response?
APS Cool Reward offers larger battery rebates ($3,750) and higher VPP earnings ($150-500/year), but requires a home battery. ED3 Peak Rewards requires only a smart thermostat — much lower barrier. The $25/year + thermostat rebate is smaller but free to join.
Can I stack ED3 rebates with federal tax credits?
Yes. ED3 rebates are utility incentives. Federal tax credits (like the 25C heat pump credit or 30% battery ITC) are independent federal programs. They stack fully. You claim the federal credit on your tax return and the ED3 rebate through ED3 directly.
