A comprehensive, data-driven analysis of residential electricity rate trends across Massachusetts, Connecticut, Rhode Island, Maine, New Hampshire, Vermont, New Jersey, Pennsylvania, and Texas — with projections through 2030.
Residential electricity rates increased an average of 20% across NuWatt's 9-state territory from 2021 to 2026. The average rate across all states is 24¢/kWh. Massachusetts leads at $33¢/kWh (up 28%), while Maine saw the fastest growth at +30%. No state experienced a rate decrease. Projections through 2030 show continued increases of 2-5% annually driven by aging infrastructure, fuel costs, and electrification demand. Solar locks in electricity costs at $0.06-$0.08/kWh for 25 years, providing a hedge against every dollar of future rate increases.

Electricity rates are the single largest factor in the financial case for solar. Yet most homeowners have no idea how fast their rates are climbing or what they will pay over the next 10 to 25 years if they stay on grid power. This report aggregates publicly available data from the U.S. Energy Information Administration (EIA), state Public Utility Commission (PUC) filings, ISO-NE and ERCOT market reports, and individual utility tariff schedules to give homeowners in our 9-state service area a clear picture of where rates have been, where they are now, and where they are going.
Every data point in this report is sourced, every projection methodology is explained, and every chart can be independently verified. We encourage journalists, bloggers, researchers, and homeowners to cite this report with attribution.

Rates vary within each state depending on your utility. Here are the major utilities in each state with their current average residential rates.
Four systemic forces are pushing electricity costs higher across all 9 states. None of these forces are temporary, and all are expected to persist or accelerate through at least 2030.
Transmission and distribution systems built 40-60 years ago need replacement. Utilities recover billions in upgrade costs through rate cases that raise your bill. ISO-NE transmission charges alone doubled from 2019 to 2025.
New England generates 50%+ of its electricity from natural gas, but pipeline capacity is constrained. Every winter price spike flows directly to ratepayers. The 2022-2023 winter saw wholesale prices 3x normal, adding $500+ to annual bills.
EVs, heat pumps, and data centers are increasing electricity demand across all 9 states. More load on the same grid means higher peak costs. ERCOT in Texas and ISO-NE in New England both set demand records in the past 18 months.
Offshore wind procurement, nuclear subsidy programs (ZECs in NJ), renewable portfolio standard compliance, and grid interconnection upgrades all add to the supply cost. These are policy-driven costs that will persist for decades.
Every cent per kWh of rate increase costs you real money. This table shows the monthly and annual cost impact of different rate increases at various usage levels.
| Household Type | Monthly kWh | +1¢ Impact/mo | +3¢ Impact/mo | +5¢ Impact/yr | +10¢ Impact/yr |
|---|---|---|---|---|---|
| Small home / apartment | 500 | +$5.00 | +$15.00 | +$300 | +$600 |
| Average home | 750 | +$7.50 | +$22.50 | +$450 | +$900 |
| Larger home / EV owner | 1,000 | +$10.00 | +$30.00 | +$600 | +$1,200 |
| All-electric home | 1,500 | +$15.00 | +$45.00 | +$900 | +$1,800 |
Massachusetts has already experienced a +5¢/kWh increase in a single year (2023-2024). For a home using 750 kWh/month, that single year's increase added $450 annually to their electricity bill — permanently.

Data: EIA Electric Power Monthly (Table 5.6.a), state PUC filings, ISO-NE/ERCOT market data. Projections assume historical CAGR continues. Actual rates may vary by utility, tariff class, and usage. Solar locked-in rate of $0.07/kWh based on average NuWatt system LCOE (owned systems, 25-year lifespan).
Solar panels produce electricity at a fixed cost for their entire 25+ year lifespan. Once installed, your rate never changes — regardless of what happens to utility prices. Here is the math.
Levelized Cost of Energy (LCOE) divides the total cost of a solar system (equipment + installation + maintenance) by the total electricity it produces over its lifetime. For a typical NuWatt installation:
$28,000
Avg system cost (after incentives)
400,000+
kWh produced over 25 years
$0.07/kWh
Locked-in LCOE
As time-of-use (TOU) rate structures expand across the Northeast and Texas, battery storage creates an additional layer of protection against rising rates.
Battery stores excess solar production during the day for use at night. Maximizes the amount of $0.07/kWh self-generated electricity you consume instead of buying grid power at $0.14-$0.33/kWh.
Charge your battery during off-peak hours (typically 10¢-15¢/kWh) and discharge during on-peak hours (25¢-45¢/kWh). The spread generates $300-$800/year in avoided cost depending on your utility.
In MA, CT, and RI, ConnectedSolutions pays $1,000-$1,500/year for battery discharge during peak grid events. This revenue accelerates battery payback and effectively pays you to reduce grid strain.
As utility rates climb 3-5% annually, the gap between your locked-in solar cost and the grid rate widens every year. A battery amplifies this by ensuring you use as much of your own solar production as possible (instead of selling it back at unfavorable net metering rates) and by capturing additional value through TOU arbitrage and demand response programs. In year 1, the savings are good. By year 10, they are dramatic. By year 25, the cumulative difference is $40,000-$80,000 depending on your state.
Five-year trends compare Q1 2021 to Q1 2026 EIA residential rates. Ten-year trends compare Q1 2016 to Q1 2026. Percentage changes are calculated as ((current - prior) / prior) * 100. Compound annual growth rates (CAGR) are derived as (current/prior)^(1/years) - 1.
Projections for 2027-2030 assume historical CAGR continues forward. This is a conservative methodology: actual rates could increase faster due to fuel price spikes, extreme weather events, or accelerated infrastructure spending. We do not apply any discount for potential rate decreases, as no state in our service area has experienced a sustained residential rate decrease in the past 20 years.
Solar locked-in rate of $0.06-$0.08/kWh is based on the levelized cost of energy for a typical NuWatt residential installation: system cost after applicable incentives, divided by total estimated production over 25 years (accounting for 0.5% annual panel degradation). The $0.07/kWh figure used in comparisons represents the median across our 9-state territory.
Utility rates have increased 20% in 5 years, and every projection shows them continuing to climb. Solar locks in your rate at $0.07/kWh for 25 years. The math is simple.
