GREENVILLE ENERGY SAVINGS

Smart thermostats pay for themselves in under a year in Greenville’s climate, where AC runs 6+ months annually. Rebate programs are available statewide in SC — but which rebate you qualify for depends on your specific utility provider.

**Greenville County utility providers** — Greenville County is served by multiple electric utilities depending on your address:

- **Greenville Electric Cooperative** — Serves most of rural Greenville County

- **Dominion Energy SC** — Serves Greenville city and surrounding areas

- **SCE&G (now Dominion Energy SC)** — Legacy service areas merged into Dominion

Check your power bill to confirm your provider, then visit their rebate portal directly.

**Rebate programs available statewide in SC**

- **Dominion Energy SC** — Smart thermostat rebates available online; amounts vary by model and program cycle

- **Greenville Electric Cooperative** — Member rebate programs through Touchstone Energy; check blueridge.coop for current offers

- **Federal tax credit** — Energy-efficient home improvement credit (25C) may cover 30% of qualifying HVAC controls

**Recommended models** — Ecobee SmartThermostat Premium and Google Nest Learning Thermostat are the most rebate-eligible models across SC utility programs. Both available at Lowe’s of Greenville (1280 Woodruff Rd) and Home Depot Greenville (1339 Woodruff Rd).

**Installation tip for Greenville homes** — Older Greenville homes (pre-1990) often lack a C-wire. Both Ecobee and Nest ship with C-wire adapters, but heat pump systems (common in Greenville County) may require a licensed HVAC tech for wiring — budget $75–150 for professional install on heat pump systems.

**Savings estimate** — ENERGY STAR data shows smart thermostats save an average of $50–$100/year in HVAC costs. In Greenville’s extended cooling season, savings typically run at the higher end.
