Appliances & Rebates

National Grid is proud to be a sponsor of the MASS Save program. MASS Save has helped make Massachusetts one of the most efficient states in the country through educating the commonwealth on energy efficient appliances and advertising the rebates and discounts offered.

On the MASS Save website, you can find a list of energy star appliances. Upon clicking on each appliance, there is a short description explaining how each appliance works, the types of appliances, its advantages, and other considerations before deciding whether to buy the appliance. There is also a section that highlights possible rebates if you decide to purchase the appliance.

The overarching categories include appliances, heating and cooling, building products, lighting, commercial food service equipment, office equipment, water heaters, electronics, and data centers.

We recommend that you go to our page on solar for more information regarding solar panels. You have the option to search for your needs, view online quotes and ask advice about the products.

Electric Vehicles

Sure. Each of the interns have learned how to use the EV charging station outside the Hub. There are also several videos online that demonstrate how to charge an electric vehicle.

Because charging your EV requires electricity, the rate is not fixed. Instead, it is variable, which means that the rate will change depending on the time of day, the local demand, and the amount that you use. As a rule of thumb, an electric car can travel 1 mile for every 3 –4 kW of energy. Electricity rates are around 20 cents per kWh as of June 2022. The total time to charge your vehicle could take anywhere from 30 minutes to 12 hours. It depends on the size of the battery, the age of the vehicle, the speed of the charging port, and the battery’s health.
