Rhode Island electricity rates are climbing fast — and they’re already well above the national average. Here’s what that means for your wallet.
Rhode Island’s average electricity rate hit 28.1 cents per kWh in 2024 — nearly double the national average of 16.5 cents. Since 2021, rates have risen more than 26%, putting steady pressure on household budgets.
Solar panels can help offset those rising costs. By generating your own electricity at home, you rely less on the grid — and less on utility rates you can’t predict or control.
With Palmetto’s LightReach program, you can go solar with no upfront cost. You pay a fixed monthly rate — often lower than your current bill — while Palmetto owns, monitors, and maintains the system for you.
Price of Energy: Rhode Island vs National Average
Rhode Island Area Utility Providers
Rhode Island has one primary electric utility: Narragansett Electric. Based on 2023 data — the most recent available — Narragansett customers paid around 27.20¢ per kWh, well above the national average of 16.00¢ per kWh.
That gap is significant. Rhode Island’s rates are driven by aging grid infrastructure, heavy reliance on natural gas, and limited regional energy diversity — factors pushing costs nearly 70% above the national average.
For homeowners paying that much per kWh, solar can help stabilize monthly energy costs. Palmetto’s LightReach program requires no upfront cost — Palmetto owns and maintains the system, includes a 90% Production Guarantee, and your rate is fixed from day one.

Rhode Island Solar Incentives
Rhode Island offers a strong set of solar incentives in Rhode Island — from cash grants and tax exemptions to long-term bill credits — that can meaningfully reduce the cost of going solar.
State programs like the Renewable Energy Fund grant, the REG Program, net metering, and both the sales and property tax exemptions work together to lower your upfront costs and improve your long-term savings. A battery storage system can unlock additional rebates as well.
Note: The federal 30% residential solar tax credit was eliminated by the 2025 Big Beautiful Bill. State and local incentives still apply. With a Palmetto LightReach lease, Palmetto handles the commercial tax credit and passes those savings through via lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Renewable Energy Fund (REF) – Small Scale Solar Grant | Rebate | A cash grant of $0.65 per watt (up to $5,000) for Rhode Island homeowners who install a new solar energy system, with an additional $2,000 adder for simultaneously installing battery storage. | Learn More |

The Renewable Energy Fund (REF) Small Scale Solar Grant, administered by the RI Commerce Corporation, provides Rhode Island homeowners with a cash grant of $0.65 per watt, capped at $5,000, to help offset the upfront cost of a new solar installation. If you also install a battery storage system at the same time as your solar panels, you can receive an additional $2,000 Energy Storage Adder, bringing the maximum residential incentive to $7,000. Grant rounds are offered in spring, summer, and fall each year on a first-come, first-served basis.
To be eligible, you must own the property in Rhode Island where the system is being installed, and the site must meet a minimum Total Solar Resource Fraction (TSRF) of 80%, verified through a shade analysis conducted by your installer. Your installer applies for the grant on your behalf — you must apply before your system receives Permission to Operate (PTO) from RI Energy, as you are no longer eligible once PTO is granted.
Important: The REF grant is only available for net-metered systems and cannot be combined with the Renewable Energy Growth (REG) Program. You must choose one or the other. After installation is complete and final documentation is submitted, payment is typically processed within 6–8 weeks, with a total timeline of 6–12 months from application to check.
The Renewable Energy Growth (REG) Program, administered by Rhode Island Energy, allows homeowners with solar systems up to 25 kW DC to sell their electricity generation to the grid at a fixed, guaranteed price for the duration of their contract (15 or 20 years). The 2026 ceiling rate is approximately $0.2723/kWh, meaning an average 8 kW system can earn roughly $2,642 per year in REG payments. Participants receive bill credits up to the amount owed, with any excess generation paid out as a direct deposit.
Enrollment opens on April 1st each year and is available on a first-come, first-served basis until the program’s allocation is fully subscribed — historically, the 40 MW residential/small commercial allocation fills within weeks of opening. To qualify, you must be an RI Energy customer with a solar system sized to produce no more electricity than your historic or estimated annual usage.
Important: The REG Program and the REF Grant are mutually exclusive — you must choose one or the other. However, REG participants are eligible to also participate in the ConnectedSolutions Battery Demand Response Program if they have a battery storage system, making it possible to stack REG income with battery incentives.
Rhode Island’s Net Metering Program allows customers with solar systems to earn bill credits for excess electricity sent to the grid. For systems installed after April 15, 2023, Rhode Island Energy credits exported energy at 80% of the retail rate — currently approximately $0.232/kWh based on RI Energy’s ~$0.29/kWh retail rate. Customers of municipal utilities (Pascoag Utility District and Block Island Power Company) receive full 1:1 retail rate credits for exported energy. Credits roll over month to month throughout the billing year.
Net metering allows you to generate credits when the sun is shining and apply them when you need to draw from the grid, dramatically reducing or even eliminating your monthly electric bill. Systems can be credited for generation up to 125% of your on-site annual consumption. At the end of the billing year (March for RI Energy), any remaining excess credits are paid out at the avoided cost rate (typically $0.03–$0.05/kWh).
Rhode Island law protects net metering terms through 2039, giving homeowners installing in 2026 at least 13 years of guaranteed program access. Note that net metering is paired with the REF grant and is not available to participants in the REG Program on the same system. A comprehensive policy review is underway with results expected by October 1, 2026, though current protections remain in effect.
Rhode Island’s Solar Sales Tax Exemption waives the state’s 7% sales tax on all solar photovoltaic equipment and installation labor. Covered items include solar panels, inverters, racking, wiring, solar batteries, and even EV chargers installed as part of a solar project. This exemption is applied automatically at the point of sale — no application or paperwork is required from the homeowner.
The financial savings are significant: on a typical residential solar installation, the exemption can save homeowners over $1,900. If a battery storage system is also included, total savings can exceed $2,900. These savings are realized immediately at the time of purchase, reducing your net installation cost from day one.
This exemption applies to both residential and commercial solar projects throughout Rhode Island and covers the full scope of a solar installation — equipment and labor alike — making it one of the most straightforward and broadly applicable incentives available to RI solar buyers.
Under Rhode Island General Laws §44-3-21, solar energy systems are exempt from local property tax assessment for 20 years. This means that even though a solar installation typically increases a home’s market value, the added value of the solar system is completely excluded from the assessed value used to calculate your property taxes. Installing solar will not raise your property tax bill.
The financial benefit is substantial: solar panels can add meaningful value to your home while saving you an estimated ~$362 per year in property taxes that would otherwise be owed — totaling approximately $7,240 in savings over 20 years. This exemption applies to both primary and secondary residences across Rhode Island.
No special application is required — the exemption is applied automatically when your property is assessed. After year 20, your municipality may include the remaining value of the solar system in your property assessment; however, by that point, solar panels typically have minimal assessed value due to depreciation, so the practical impact is very limited.
The ConnectedSolutions Battery Demand Response Program, administered by Rhode Island Energy, compensates homeowners with battery storage systems for allowing the utility to dispatch their stored energy during periods of peak grid demand. Participants earn $225 per average kW performed each summer season — for example, a 5 kW battery can earn approximately $1,125 per year. The program has received regulatory approval through the 2024–2026 period, and participants can lock in their rate for the first five summers of enrollment.
Demand response events occur between June and September, from 3:00 PM to 8:00 PM, with a maximum of 60 events per summer and no single event lasting longer than 3 hours. Popular batteries such as the Enphase IQ 10 and Tesla Powerwall qualify for the program. Participation is largely automated — your battery’s software manages the response events with minimal homeowner involvement.
This program is available to both net-metered customers and REG Program participants, making it one of the few incentives that can be stacked regardless of which primary solar program you choose. Additionally, low-income customers on the A-60 rate may qualify for a 0% interest financing loan (no down payment, up to $25,000 lifetime cap) for battery installation, which can be combined with the REF Energy Storage Adder for maximum savings.
The REF Energy Storage Adder is a $2,000 cash grant available to Rhode Island homeowners who install a battery storage system simultaneously with their solar panels through the Renewable Energy Fund (REF) program. This adder is available regardless of how many batteries are installed — whether you add one battery or multiple, the adder remains $2,000 for residential projects. For commercial systems, the maximum battery adder is $40,000.
The Energy Storage Adder is layered on top of the base REF solar grant ($0.65/watt, up to $5,000), bringing the maximum combined residential incentive to $7,000. To qualify, the battery storage system must be installed at the same time as the solar system — retrofitting a battery onto an existing solar installation does not qualify for this adder.
Like the base REF grant, the Energy Storage Adder is only available for net-metered systems and cannot be combined with the REG Program. Your installer applies for this adder on your behalf as part of the standard REF grant application process. This incentive can also be combined with the ConnectedSolutions Battery Demand Response Program for additional ongoing annual earnings from your battery.

Go Solar with LightReach — No Upfront Cost
In Rhode Island, Palmetto’s LightReach program offers a Power Purchase Agreement (PPA) through Rhode Island Energy (formerly National Grid) under their Net Metering program. With a PPA, you pay a set rate per kilowatt-hour (kWh) for the solar energy your system produces — rather than a fixed monthly amount. That means your bill may vary slightly by season, but you’re always paying for clean energy at a predictable rate, not whatever the utility decides to charge.
Compared to paying cash upfront, a PPA through LightReach requires no upfront investment. There’s no large check to write, no maintenance to manage, and no repair bills to worry about. Since Palmetto Finance owns the system, we handle everything — design, installation, permitting, and ongoing maintenance — all included. If your panels don’t hit our 90% Production Guarantee, we’ll credit you the difference.
Unlike most third-party solar agreements, Palmetto’s LightReach plan centralizes everything into one inclusive price. You get premium all-black panels, a high-efficiency inverter, comprehensive project management, and a protection program — all managed by Palmetto. It’s a straightforward, low-risk way to go solar in Rhode Island.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!
