How it Works

Couple At Home During The Day

On hot summer days, when the grid is stressed, reducing energy can save energy costs and decrease pollution—and MassSave makes it easy!

After enrolling your qualified thermostat, National Grid will automatically send a signal to your thermostat to precool your home 3°F before the peak event and increase your thermostat setting 4°F during the peak event.

Peak events may occur during:

  • June-September
  • Non-holidays
  • Between 3-8pm

There are typically 15 peak events every summer – each event lasts only three hours.

You can opt out of a peak event at any time by changing your thermostat setting.

If this is not a good fit for you, we may unenroll you the following year.

Supported thermostats include:

  • Building36
  • ecobee
  • Emerson
  • Honeywell Home (including Lyric)
  • Lux
  • Nest
  • vivint.SmartHome

A central air conditioner or central heat pump is an air conditioner that cools an entire (or at least the majority) of a home or small business. This includes both ducted and ductless systems.

Window air conditioners and heating systems that do not cool are not central air conditioners or central heat pumps. 

To participate, your thermostat must be connected to a central air conditioner or central heat pump.

There are many options for purchasing a supported Wi-Fi thermostat.

For Homeowners, a supported Wi-Fi Thermostat can be purchased at:

  • Your local hardware stores
  • Online retailers, like Amazon
  • Through the MassSave website
  • If eligible, through a MassSave energy assessment

Unfortunately, you are not eligible for ConnectedSolutions if you don't have a central air conditioner or central heat pump.
