What Is Mass Save ConnectedSolutions? The Battery Incentive Program Explained
Mass Save ConnectedSolutions is a performance-based incentive program that pays Massachusetts homeowners for sharing stored energy from their solar batteries with the electric grid during periods of peak demand. By allowing utilities like National Grid and Eversource to draw power from residential batteries when the grid is stressed, participants receive annual incentive payments based on the average amount of power they contribute.
The program represents a shift toward a decentralized “virtual power plant” model, where individual homes become active participants in grid stability. For Massachusetts residents, this program significantly offsets the cost of high-quality battery systems like the Tesla Powerwall. By participating, homeowners not only gain the security of backup power during outages but also turn their energy storage system into a revenue-generating asset that pays for itself over several years.
Key Characteristics of ConnectedSolutions
- Performance-Based Payments: Homeowners are paid based on the average kilowatt (kW) performance of their battery during “demand response” events, rather than a flat one-time rebate.
- Grid Support Strategy: The program is designed to reduce the need for “peaker plants,” which are often the most expensive and carbon-intensive power plants to operate.
- Automated Participation: Once enrolled, the utility manages the discharge of the battery remotely during peak events, requiring no manual action from the homeowner.
- Seasonal Incentive Structure: Payments are calculated based on performance during the summer season (June through September), when grid demand is highest due to air conditioning usage.
How ConnectedSolutions Works for Homeowners
The program operates through a series of scheduled “events” where the utility pulls power from your battery. Here is the typical process for a participant:
- Installation and Enrollment: A homeowner works with a certified installer like Boston Solar to install a compatible battery system and submits an application to their utility provider (National Grid, Eversource, or Unitil).
- Event Notification: During the summer months, the utility identifies periods of peak demand. They typically send a notification to the battery software 24 hours before a discharge event occurs.
- Energy Discharge: During the event—usually a 2-to-3-hour window in the late afternoon—the battery automatically discharges its stored solar energy into the home or back to the grid.
- Reserve Protection: Homeowners can set a “reserve” limit, ensuring the battery never drains below a certain percentage (e.g., 20%) to maintain backup power for emergencies.
- Annual Payment: At the end of the season, the utility calculates the average kW contributed across all events and issues a check to the homeowner.
Common Misconceptions
| Myth | Reality |
|---|---|
| My battery will be empty if the power goes out. | The program is designed to leave you with a reserve, and utilities rarely call events when severe weather (and potential outages) are forecasted. |
| I have to manually turn on my battery. | All events are handled automatically through the battery’s smart software and your utility’s dispatch system. |
| The program is only for large solar farms. | ConnectedSolutions is specifically designed for residential and small commercial battery owners. |
| This replaces the SMART program. | ConnectedSolutions is an additional incentive that can often be “stacked” with the Massachusetts SMART program. |
ConnectedSolutions vs. Traditional Solar Incentives
While traditional incentives like the Federal Solar Tax Credit (ITC) provide a one-time reduction in the upfront cost of equipment, ConnectedSolutions provides ongoing, performance-based income. Unlike Net Metering, which credits you for the electricity you produce, ConnectedSolutions pays you specifically for the timing of when you provide that electricity to the grid. This makes battery storage financially viable by creating a clear return on investment (ROI) timeline that wouldn’t exist through backup power benefits alone.
Practical Applications and Real-World Examples
In 2026, Massachusetts homeowners are seeing substantial returns through this program. For example, a typical Tesla Powerwall installation might contribute an average of 5 kW per event. With current incentive rates often exceeding $200 per kW-summer in certain utility territories, a homeowner could earn over $1,000 annually just for participating.
Over the five-year term of the typical ConnectedSolutions agreement, these payments can cover a significant portion of the initial battery investment. Beyond the financial gain, residents in high-traffic areas or regions with aging infrastructure contribute to a more resilient local grid, preventing brownouts for their neighbors while ensuring their own home remains powered during winter storms or summer heatwaves.

FAQ
Frequently asked questions for this article
How much does Mass Save ConnectedSolutions pay?
Participants are paid based on the average kilowatts (kW) of power their battery contributes during peak demand events. For example, if your utility pays $225 per kW and your battery averages a 5 kW discharge, your annual payment would be $1,125.
What batteries are compatible with ConnectedSolutions?
Most major smart battery systems are eligible, including the Tesla Powerwall, SolarEdge Home Battery, and Enphase IQ Battery. It is important to verify compatibility with your installer before purchase.
Will my battery be drained during a power outage?
No. You can set a reserve limit (typically 20% or higher) to ensure your battery always has enough power to keep your essential appliances running if a blackout occurs.
How long is the ConnectedSolutions contract?
The program typically requires a five-year commitment, during which you receive annual payments for your participation during the summer and winter seasons.
