Yes. ConnectedSolutions pays up to $225/kW annually for commercial battery demand response, making battery storage a genuine profit center. A 100 kW commercial battery generates $22,500/year from ConnectedSolutions alone, plus $8,000-$15,000/year in demand charge reduction. When paired with solar, the 30% federal ITC and MACRS depreciation cut upfront costs by 40-50%, driving payback to 4-6 years. The 10-year NPV for a typical 100 kW/400 kWh system ranges from $185,000 to $245,000.
ConnectedSolutions is Massachusetts' utility-administered demand response program. Commercial battery owners earn revenue by discharging stored energy during grid peak events. The program operates through all three investor-owned utilities: Eversource, National Grid, and Unitil.
$225/kW/year
Highest-paying tier. Battery dispatches during afternoon/evening peaks (typically 2-7 PM) on hot summer days. Events last 1-3 hours. Ideal for businesses with predictable load profiles.
$200/kW/year
Fewer dispatch events focused on critical grid peaks. Called during extreme heat waves and highest-demand periods. Slightly lower compensation but less cycling wear on batteries.
$175/kW/year
Fully automated dispatch based on real-time grid signals. Battery responds within minutes to frequency regulation and peak demand signals. Requires compatible inverter and internet connection.
$50/kW/year
New pilot program addressing winter peak demand from heating loads. Events triggered during cold snaps when electric heating demand spikes. Stacks on top of summer program revenue.

Breakeven in Year 3
With the 30% ITC applied at installation and $37,500 in annual revenue, the system reaches positive cumulative cash flow during Year 3. By Year 10, the total return on the initial investment exceeds $268,000, representing a 191% return on the net investment.
Demand charges account for 30-50% of commercial electricity bills in Massachusetts. These charges are based on your single highest 15-minute demand reading each billing cycle, meaning one brief spike can inflate your entire monthly bill.
Massachusetts utilities bill commercial customers on two components: energy charges (per kWh consumed) and demand charges (per kW of peak demand). Your demand charge is set by your highest 15-minute average power draw in the billing period, regardless of how briefly that peak occurred.
For example, if your building draws 200 kW for just 15 minutes during a hot afternoon but averages 80 kW the rest of the month, you pay demand charges on the full 200 kW. At Eversource's GV rate of $13.75/kW/month, that single spike costs $2,750 in demand charges alone.
Battery storage eliminates these spikes through peak shaving: the battery controller monitors real-time power consumption and automatically discharges when demand approaches a pre-set threshold, effectively capping your peak demand at a lower level.

Load Profile Analysis Is Critical
Effective peak shaving requires detailed analysis of your building's 15-minute interval data (available from your utility upon request). Key factors include: peak demand magnitude, peak duration and frequency, time-of-use rate windows, seasonal demand patterns, and coincidence of peak demand with ConnectedSolutions dispatch events. NuWatt provides complimentary load profile analysis for all commercial battery assessments, identifying the optimal battery size to maximize combined demand charge savings and ConnectedSolutions revenue.
Pairing battery storage with solar transforms a good investment into a great one. Solar+battery systems unlock the full federal ITC, SMART 3.0 battery adder, and energy charge savings on top of ConnectedSolutions and demand charge reduction.
Commercial solar panels produce maximum power from 10 AM to 3 PM, but many commercial buildings peak later (3-7 PM) when solar output is declining. Battery storage bridges this gap by storing midday solar surplus and discharging during the late-afternoon peak. This maximizes self-consumption, reduces grid exports, and eliminates demand spikes simultaneously.
Without a battery, excess midday solar is exported at net metering rates (Class II: retail minus minimum charge). With a battery, that same energy is consumed on-site during peak hours, offsetting the full retail rate ($0.22-$0.30/kWh) plus reducing demand charges. The value of self-consumed solar is typically 50-80% higher than exported solar.
The Section 48/48E Investment Tax Credit applies to battery storage when the battery is charged at least 80% from on-site solar. The base 30% ITC applies to the combined cost of solar panels, inverters, battery, and installation. Additional bonus adders may apply:
A $300,000 solar+battery system with 30% base ITC saves $90,000 in federal taxes. With domestic content and energy community adders (50% total), the savings jump to $150,000.
Massachusetts allows commercial solar+battery systems to participate in both SMART 3.0 and ConnectedSolutions simultaneously. The SMART 3.0 program offers a battery storage adder for systems that pair solar with on-site storage, providing additional per-kWh incentive payments over the 20-year SMART term.
The key to successful stacking is coordinating dispatch priorities. During ConnectedSolutions events, the battery prioritizes grid dispatch (earning $225/kW). Outside of events, the battery focuses on demand charge management and solar self-consumption optimization. The SMART 3.0 production incentive is based on solar output regardless of whether the energy passes through the battery.

MACRS Depreciation: Extra 20% Bonus in 2026
Commercial battery+solar systems qualify for 5-year MACRS accelerated depreciation. In 2026, the additional 20% first-year bonus depreciation is still available (drops to 0% in 2027). The depreciable basis is reduced by half the ITC amount. For a $300,000 system with 30% ITC, the depreciable basis is $255,000, with $51,000 (20%) deductible in Year 1 via bonus depreciation. This significantly accelerates the tax benefit and improves Year 1 cash flow. See our full MACRS depreciation guide.

Collect 12-15 months of 15-minute interval data from your utility meter. This reveals your actual demand profile.
Identify peak demand events: magnitude (kW), duration (minutes), frequency, and seasonality.
Define your target peak demand ceiling. Typically 30-50% below current peak for optimal battery ROI.
Battery kW = Current Peak - Target Peak. This determines the discharge rate needed during peaks.
Battery kWh = Battery kW x Peak Duration (hours). Rule of thumb: 3-4x the kW rating for commercial applications.

Common questions about commercial battery storage and ConnectedSolutions in Massachusetts.
ConnectedSolutions is Massachusetts’ utility-run demand response program that pays commercial battery owners to discharge stored energy back to the grid during peak demand events. When the grid is stressed (hot summer afternoons, cold winter evenings), your utility sends a dispatch signal and your battery automatically discharges for 1-3 hours. You earn $175-$225 per kW of enrolled capacity annually through the summer program, plus an additional $50/kW through the winter pilot. For a 100 kW commercial battery, that translates to $22,500-$27,500 in annual revenue just from ConnectedSolutions alone. The program runs through Eversource, National Grid, and Unitil.
