Projected 2030 rate
Rhode Island residential rates have increased every single year. The 2022 spike was the worst — a 17.8% increase driven by natural gas market chaos.
The math is relentless: A RI household using 700 kWh/month paid $126/month in 2016. That same usage costs $203/month in 2026 — an extra $924/year with no change in consumption.
Understanding the drivers helps you see why rates will not stabilize anytime soon — and why solar is the best hedge.
RI generates most electricity from natural gas. As a constrained New England market, gas prices spike every winter. The 2022 rate shock was 100% gas-driven.
RI Energy is deploying advanced metering infrastructure (AMI) and grid upgrades. These multi-billion dollar capital investments are recovered through rate increases.
Revolution Wind (400 MW) and other offshore projects add capacity but require transmission investments. Contract costs pass through to ratepayers.
RI has the most aggressive renewable target in New England. Compliance costs (REC purchases, grid storage, transmission) will increase rates through 2033.
Transmission costs are the least controllable component for RI ratepayers. ISO-NE regional transmission charges rise 3-5% annually. Distribution infrastructure is aging.
Based on historical trends, RI Energy rate filings, planned infrastructure investments, and the 100% renewable by 2033 mandate.
| Year | Low Scenario | Mid Scenario | High Scenario |
|---|---|---|---|
| 2027 | $0.30 | $0.31 | $0.33 |
| 2028 | $0.31 | $0.33 | $0.36 |
| 2029 | $0.32 | $0.34 | $0.38 |
| 2030 | $0.33 | $0.36 | $0.40 |
| 2033 | $0.36 | $0.40 | $0.47 |
Methodology: Low scenario assumes 3% annual increases (historical minimum). Mid scenario uses 5% (10-year average). High scenario uses 7% (reflects 2022-type spikes becoming more common with gas volatility and grid investment). All scenarios are pre-inflation.
Rhode Island has the 3rd highest residential electricity rates in New England — and 70% above the national average.
Solar panels produce free electricity for 25+ years. As rates rise, each kWh your system produces becomes more valuable. Here is what that means for an 8 kW RI system:
| RI Rate | Annual Savings (8 kW) | 20-Year Value | Payback | Verdict |
|---|---|---|---|---|
| $0.18 (2016) | $1,900 | $38,000 | 14+ years | Marginal |
| $0.29 (2026) | $3,100 | $62,000+ | 7-9 years | Strong |
| $0.36 (2030 est.) | $3,800 | $76,000+ | 5-7 years | Excellent |
| $0.40 (2033 est.) | $4,200 | $84,000+ | 4-6 years | Exceptional |
When you install solar, you effectively lock in your electricity cost at $0/kWh for the energy you produce. As RI rates climb from $0.29 to $0.36-0.40, your savings grow every year without you doing anything. A system installed in 2026 saves more in 2030 than it does today.
The REG program pays $0.27/kWh for 15 years on top of net metering credits. As rates rise, your net metering credits also rise (they are pegged to a percentage of retail rate). REG income + growing net metering credits = compounding returns.
You cannot control RI Energy rates. But you can control how much of your power comes from the grid.
8 kW system costs ~$23,000. With REG ($0.27/kWh x 15yr) + REF ($5,000) + tax exemptions, payback is 7-9 years. Free electricity for years 10-25+.

Learn moreRhode Island residential electricity rates increased from $0.18/kWh in 2016 to $0.29/kWh in 2026 — a 61% increase over 10 years. The biggest single-year spike was 2021-2022 (+17.8%) driven by natural gas price volatility. RI rates have never decreased year-over-year in this period.
Three main factors: (1) Heavy dependence on natural gas for electricity generation in a supply-constrained New England market, (2) Grid modernization investments (AMI, smart grid infrastructure) being recovered through rates, and (3) Offshore wind integration costs and the ambitious 100% renewable by 2033 mandate. RI is the 3rd most expensive state in New England and roughly 70% above the national average.
Based on historical trends, regulatory filings, and planned infrastructure investments, RI electricity rates are projected to reach $0.33-$0.40/kWh by 2030. The wide range reflects uncertainty in natural gas prices, offshore wind contract costs, and the pace of grid modernization. Under all scenarios, rates continue to rise — the only question is how fast.
Rhode Island has the 3rd highest residential rates in New England at $0.29/kWh (March 2026). Massachusetts is highest at ~$0.32/kWh, Connecticut is ~$0.30/kWh. New Hampshire ($0.27), Maine ($0.23), and Vermont ($0.21) are lower. All New England states are significantly above the US average of ~$0.17/kWh.
Yes. Solar panels lock in your electricity cost at the installed price — effectively $0/kWh for the energy you produce and consume. As RI rates rise from $0.29 today toward $0.36-0.40 by 2030, every kWh your solar system produces becomes more valuable. A system that saves $3,100/year today could save $4,200/year by 2033. Over 25 years, this compounding effect adds tens of thousands of dollars in value.
Not in the short term. Achieving 100% renewable by 2033 requires massive capital investment: offshore wind farms, battery storage, transmission upgrades, and grid modernization. These costs pass through to ratepayers. Long-term (post-2035), renewable energy costs may stabilize rates as fuel costs are eliminated, but the transition period (2026-2033) will likely see continued above-inflation rate increases.
Solar panels are the most effective hedge against rising rates. With no federal 25D ITC (expired December 2025), focus on: (1) REG program income ($0.27/kWh for 15 years), (2) REF rebate ($0.65/W up to $5,000), (3) 7% sales tax exemption, (4) 20-year property tax exemption. Battery storage (Connected Solutions: $225/kW summer demand response) adds further rate protection. Even without the ITC, solar payback in RI is 7-9 years due to high rates.
Higher electricity rates increase heat pump operating costs, but heat pumps remain cheaper than oil ($3.45/gal), propane ($3.58/gal), and electric resistance ($0.29/kWh x 1.0 COP). A heat pump with COP 3.0 uses $0.29 / 3 = $0.097 per equivalent kWh of heat — still far less than oil or propane. Pairing solar + heat pump locks in both electricity AND heating costs. Clean Heat RI covers 60% of heat pump costs (up to $11,500).
Every year you wait, rates go up and your solar savings shrink. At $0.29/kWh and climbing, solar payback is now 7-9 years in Rhode Island. REG enrollment opens April 1.
