Earn cash from your Powerwall and create a cleaner, stronger grid
National Grid customers in Massachusetts or Rhode Island can now enroll their Powerwall in ConnectedSolutions, a program that links batteries across the state together to create a large supply of sustainable energy to be used during peak demand.
Earn hundreds of dollars each year by participating in this virtual power plant with other customers, and know you’re contributing to a cleaner, stronger grid—all with the same self-powered and emergency backup features of Powerwall.
By pairing Powerwall with solar, customers can unlock additional incentives in both states. In some cases, these programs can significantly reduce the cost of solar and completely cover the cost of Powerwall.
Maximize the value of Powerwall and earn hundreds of dollars every year

What is ConnectedSolutions?
ConnectedSolutions is a program that reduces overall electric use during periods of high energy demand using connected devices like Powerwall. Tesla and National Grid are working together to bring hundreds of Powerwalls together into a virtual power plant to support the grid in a clean way.
Who is eligible?
Powerwall owners in National Grid territory in Massachusetts and Rhode Island.
Who could I contact with questions or if I want to apply?
If you already have a relationship with a Tesla account representative or a Powerwall installer, please work with them. If you are new to Powerwall, please fill out the form above and we’ll reach out to you.
What is the benefit of participating?
The program is designed to:
- Earn value from your Powerwall
- Provide protection during a grid outage
- Increase grid stability
- Reduce fossil fuels and support the transition to a renewables-based economy
How much can I expect to earn?
ConnectedSolutions is a performance-based program. Your payment will be based on your average power contribution during peak events. Tesla will manage your system for you to maximize your performance, but it will depend on your Powerwall system, and we don’t guarantee any dollar value.
The highest-earning Powerwall system will be one that is paired with enough solar generation to completely recharge the battery every day. These systems will be able to discharge the most capacity during events. If there is plenty of solar generation to recharge the batteries, then Powerwall could earn as much as $700 a year in MA and $1,000 a year in RI by participating in ConnectedSolutions.
Powerwall systems not paired with solar generation will not be allowed to export power to the grid, but will still be able to discharge to serve home load. This limitation will greatly reduce the earning potential, but if the home load during events averages 1kW, Powerwall can still earn as much as $200 a year in MA and $290 a year in RI.
Earnings during the first year will also depend on enrollment. You will get zero credit for events that happen before you enroll, which will reduce average performance.
How will Tesla and National Grid use my Powerwall?
You can expect National Grid to request power from your Powerwall for a few hours up to 75 days per year (roughly 60 summer days and 15 winter days). During the hottest part of summer, you can expect an event almost every weekday. Tesla will charge the battery for best event performance and command the battery to discharge during the event. At all other times, you can choose how the battery behaves through your Tesla app.
How can I ensure that I’ll still have backup energy if the power goes out?
- Severe storms: Storm Watch mode will be active 24/7/365 and will prioritize backup over participation in this program if a severe storm is forecast.
- During program events: the Powerwall will always retain at least 20 percent of its capacity as backup during events to protect against unexpected outages. Of course, program events only make up 3% of the year.
- All other times: You can set your backup preferences in your Tesla app.
When do I get paid?
The customers’ performance will be calculated and approved by National Grid at the end of each season, summer and winter.
Based on those calculations, Tesla will pay customers at the end of each season, after it receives the funds from National Grid. Summer program proceeds will be paid by late December, and winter proceeds will be paid by late May. Customers must be enrolled in the program through the end of the season in order to be eligible for that season’s payment.

Beyond ConnectedSolutions, what other programs are Massachusetts and Rhode Island customers eligible for?
Solar systems are eligible for a federal tax credit that could refund up to 30% of the system cost. If Powerwall is paired with a solar system, it may also be eligible for this tax credit.
Massachusetts solar customers are eligible for the SMART Program. SMART includes additional incentives for Powerwall.
Rhode Island solar customers are eligible for the Small Scale Renewable Energy Growth Program.
How much value can I generate by participating in these programs?
The value created by these programs will vary based on the size of the solar system and the number of Powerwalls.
For example, a Powerwall paired with an 8 kW solar system in Massachusetts could create almost $12,000 in value - $3,200 from the federal tax credit, $4,800 from the SMART storage incentive and $3,850 from ConnectedSolutions – more than enough to cover the Powerwall’s price.
These are just the values attributable to Powerwall – the solar component of a system will also create value through savings on your utility bill, the federal tax credit, SMART and Renewable Energy Growth programs.
