Eversource serves approximately 4.4 million customers across Massachusetts, Connecticut, and New Hampshire. Like National Grid, Eversource participates in two thermostat programs: a one-time purchase rebate and the ConnectedSolutions demand-response program.

Eversource Smart Thermostat Rebate

Eversource’s energy efficiency programs include rebates for qualifying ENERGY STAR smart thermostats.

Rebate amount: $50–100 per qualifying thermostat
Who qualifies: Eversource residential customers in MA, CT, or NH with ENERGY STAR certified model
How to apply: Submit through eversource.com → Save Energy → Rebates

In Massachusetts, Eversource participates in Mass Save, a statewide efficiency program. Rebates for MA customers may be processed through masssave.com. See Massachusetts Smart Thermostat Rebates (Mass Save).

ConnectedSolutions: High-Value Demand Response

Eversource is a major participant in ConnectedSolutions, the Northeast’s collaborative demand-response program. For Connecticut and New Hampshire customers, this may represent the most valuable thermostat demand-response program available.

ConnectedSolutions credits (vary by state and year):
– Massachusetts: historically $75–$170/season (among the highest US programs)
– Connecticut: $75–$130/season
– New Hampshire: $50–$100/season

Verify current season’s amounts. They change annually based on capacity needs.
