ConnectedSolutions pays battery owners $225-$275/kW in summer demand response revenue. A single Tesla Powerwall 3 (13.5 kW) earns $3,038-$3,713/summer. Available in MA, RI, and CT. Eversource pays the highest rate ($275/kW summer + $50/kW winter). National Grid pays $225/kW summer + $50/kW winter. Unitil does NOT participate.Revenue is based on battery power rating (kW), not energy capacity (kWh).

ConnectedSolutions rates vary by utility. Revenue is calculated per kilowatt (kW) of battery power capacity enrolled in the program. Note that Unitil does not participate and Eversource CT rates for 2026 are pending.
| Utility | Territory | Summer ($/kW) | Winter ($/kW) | Annual Total | Status |
|---|---|---|---|---|---|
| Eversource (MA) | Greater Boston, Western MA, Cape Cod | $275 | $50 | $325/kW | Active |
| National Grid (MA) | Central & Western MA, Worcester, Springfield | $225 | $50 | $275/kW | Active |
| Rhode Island Energy | Most of Rhode Island (~95%) | $225 | - | $225/kW | Active |
| Eversource (CT) | Most of Connecticut | - | - | - | TBD |
| Unitil (MA) | Fitchburg area (~11% of MA) | - | - | - | Not Participating |
Unitil does NOT participate in ConnectedSolutions. If you are in Unitil territory (Fitchburg, MA area), you can still install a battery for backup power and the SMART battery adder (+$0.04/kWh), but you will not receive demand response revenue.
ConnectedSolutions revenue is based on your battery's power rating (kW), not its energy storage capacity (kWh). The Tesla Powerwall 3 earns the most due to its 13.5 kW continuous discharge rating.
| Battery | Enrolled kW | Eversource Annual | NGrid Annual | 5-Year Total (Eversource) |
|---|---|---|---|---|
| Tesla Powerwall 3 | 13.5 kW | $4,388/yr | $3,713/yr | $21,940 |
| Tesla Powerwall 2 | 5 kW | $1,625/yr | $1,375/yr | $8,125 |
| Enphase IQ Battery 5P | 3.84 kW | $1,248/yr | $1,056/yr | $6,240 |
| Enphase IQ Battery 10T | 3.84 kW | $1,248/yr | $1,056/yr | $6,240 |
| SolarEdge Home Battery 400V | 5 kW | $1,625/yr | $1,375/yr | $8,125 |
| Generac PWRcell | 4.5 kW | $1,463/yr | $1,238/yr | $7,315 |
| LG RESU Prime | 5 kW | $1,625/yr | $1,375/yr | $8,125 |
| sonnen ecoLinx / eco | 5 kW | $1,625/yr | $1,375/yr | $8,125 |
Stacking tip: ConnectedSolutions revenue stacks with the SMART battery adder (+$0.04/kWh) in Massachusetts. A homeowner with an 11 kW solar system and Powerwall 3 on Eversource earns ~$4,388/yr from ConnectedSolutions plus ~$528/yr from the SMART battery adder. That is over $4,916/yr from the battery alone, before net metering savings.
ConnectedSolutions dispatches your battery during peak grid demand. Summer events generate the majority of revenue. Between events, your battery is fully available for self-consumption and backup power.
June - September
December - March
April-May, Oct-Nov
Typical event duration: 2-3 hours per dispatch event. Events usually occur on weekday afternoons during peak demand (2-7 PM). You receive advance notification via app or text. Your battery automatically dispatches and recharges from solar the following day.
NuWatt handles ConnectedSolutions enrollment as part of every battery installation in participating utility territories. The process is straightforward and typically completed within 2-4 weeks after battery installation.
NuWatt installs your qualified battery (Tesla Powerwall, Enphase IQ, etc.) and configures it for grid-interactive operation.
NuWatt submits your enrollment application to the utility or demand response aggregator. Your battery capacity (kW) is registered.
The utility verifies your battery installation and approves your enrollment. Typical approval: 2-4 weeks after submission.
Your battery begins receiving dispatch signals during peak demand events. Events are managed automatically — no action needed from you.
Revenue is paid based on your enrolled capacity and participation. Payments are typically made after each season (fall for summer, spring for winter).
5-year enrollment recommended: ConnectedSolutions is typically a 5-year commitment for best rates. Early termination may reduce your per-kW payment. NuWatt recommends the full enrollment term to maximize lifetime revenue.
Revenue scales linearly with battery count. Homeowners with multiple batteries earn proportionally more. Eversource territory numbers shown below.

Massachusetts and Rhode Island continue to invest in demand response as a grid reliability strategy. ConnectedSolutions enrollment has grown year-over-year, and utilities have maintained or increased per-kW rates. The program is expected to continue through at least 2030.
Eversource CT ConnectedSolutions rates for 2026 have not yet been finalized by PURA (Public Utilities Regulatory Authority). Previous years offered comparable summer rates to MA. This tracker will be updated as soon as CT rates are published.
An important distinction: ConnectedSolutions pays per kilowatt (kW) of power capacity, not per kilowatt-hour (kWh) of energy storage. The Tesla Powerwall 3 (13.5 kW power, 13.5 kWh storage) earns far more than two Enphase IQ 5P batteries (7.68 kW power, 10.0 kWh storage combined) despite similar energy capacity because of its higher power output.
Revenue depends on your battery capacity (kW) and utility. A Tesla Powerwall 3 (13.5 kW) enrolled in Eversource ConnectedSolutions earns approximately $3,713 in summer ($275/kW x 13.5 kW) plus $675 in winter ($50/kW x 13.5 kW) for a total of $4,388/year. On National Grid, the same battery earns about $3,713/year ($225/kW summer + $50/kW winter). Revenue is based on enrolled capacity (kW), not stored energy (kWh).
ConnectedSolutions dispatches your battery during grid peak events, typically for 2-3 hours per event. Most programs cap total dispatches at 60 hours per summer season. Between events, your battery recharges from solar and is available for self-consumption and backup power. You can set a reserve level (typically 20-30%) to ensure backup capacity remains.
Technically yes — ConnectedSolutions requires a qualified battery, not necessarily solar panels. However, without solar panels to recharge your battery for free, your battery charges from the grid at retail rates. The economics are far better with solar: your panels recharge the battery daily at no cost, making the demand response payments essentially free revenue.
Unitil serves approximately 11% of Massachusetts customers (primarily the Fitchburg area). Unitil has not opted into the ConnectedSolutions demand response program. Their smaller customer base and different grid infrastructure make the program less viable. If you are in Unitil territory, you can still benefit from battery backup and SMART battery adder payments, but ConnectedSolutions revenue is not available.
Summer events (June-September) are called during peak grid demand, typically during heat waves when air conditioning drives consumption above forecasted levels. Events usually occur on weekday afternoons (2-7 PM). Winter events (December-March) are called during extreme cold snaps. You receive advance notification and your battery is dispatched automatically by the utility or aggregator.
This tracker is updated monthly. We monitor utility rate filings, program changes, and qualifying battery lists. ConnectedSolutions rates are typically set annually by each participating utility through DPU rate proceedings. The "Last Updated" date reflects the most recent review of all program parameters.
ConnectedSolutions rates are sourced from utility DPU filings, the Massachusetts Clean Energy Center (MassCEC), and utility program pages. Rates reflect the per-kW incentive published for the 2026 program year.
Battery specifications (power rating, energy capacity) come from manufacturer datasheets and ConnectedSolutions qualifying product lists maintained by each participating utility. Enrolled kW may differ from nameplate ratings based on utility enrollment standards.
Revenue projections assume full summer and winter participation with no missed events. Actual revenue may vary based on the number and duration of dispatch events called in a given season. The 60 hours/year summer cap and 20 hours/year winter cap are utility-imposed maximums.
Rhode Island Energy rates are sourced from the RI PUC and the Rhode Island Energy demand response program page. RI Energy currently offers summer-only ConnectedSolutions.
Update frequency: This tracker is reviewed and updated monthly. Rate changes are typically announced annually by each utility through regulatory proceedings. The data was last verified on February 15, 2026.
