Cranston Electricity Prices
Cranston homeowners are paying some of the highest electricity rates in the country — and the trend is heading in one direction.
Rhode Island’s electricity rate has climbed from 22.3 cents per kWh in 2021 to 28.1 cents per kWh in 2024 — a roughly 26% increase in just three years, well above the national average of 16.5 cents per kWh.
For many Cranston homeowners exploring solar installation, this gap matters. Generating your own electricity with solar panels means relying less on the grid — and less exposure to rates that continue to rise year after year.
Over a 20–25 year system lifespan, Cranston solar panels can provide a meaningful hedge against future rate increases, giving homeowners greater predictability over one of their most consistent monthly expenses.
Price of Energy: Rhode Island vs National Average
Cranston Area Utility Providers
Cranston, RI residents are served by Narragansett Electric. According to 2023 data — the most recent available — Narragansett Electric’s rate was 27.20¢ per kWh, just above Rhode Island’s 2023 state average of 27.00¢ per kWh.
For context, the 2023 national average was 16.0¢ per kWh. Rhode Island’s higher rates are largely tied to aging regional infrastructure and constrained energy supply in the Northeast, which drives costs well above the national norm.
When electricity costs are this high, the math around solar can shift meaningfully. Generating your own power at home means relying less on the grid — and less exposure to rates that have historically trended upward in Rhode Island.

Rhode Island Solar Incentives
Cranston homeowners have access to several state and local programs that can help reduce the cost of solar installation. Here’s a look at the solar incentives in Rhode Island currently available.
Rhode Island offers a range of incentives for solar installation, including cash grants, net metering bill credits, long-term production payments, sales tax exemptions, property tax exemptions, and battery storage rebates — each designed to lower upfront and ongoing costs.
Note that the federal 30% residential tax credit was eliminated by the Big Beautiful Bill. State and local incentives remain. For those considering a solar lease, LightReach handles the commercial ITC and passes 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 |

| Solar Property Tax Exemption | Property Tax Exemption | Rhode Island law exempts the added value of a solar energy system from local property tax assessments for 20 years, so installing solar will not increase your property tax bill. | Learn More |
| ConnectedSolutions Battery Demand Response Program | Rebate | Rhode Island Energy pays battery storage owners $225 per average kW performed each summer for allowing the utility to draw on their stored energy during peak grid demand events. | Learn More |
| REF Energy Storage Adder | Rebate | An additional $2,000 cash grant available to Rhode Island homeowners who install a battery storage system at the same time as their solar panels through the Renewable Energy Fund program. | 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 in Cranston 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. Credits roll over month to month throughout the billing year.
Net metering allows residents of Cranston 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 in Cranston 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 Cranston homeowners 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.

Leasing Solar Panels
In Cranston, RI, Palmetto offers a Power Purchase Agreement (PPA) through Rhode Island Energy (formerly National Grid) with net metering. With a PPA, instead of paying a fixed monthly amount, you agree to purchase the electricity your solar panels produce at a set rate per kilowatt-hour (kWh). Because solar panels produce more power in summer than winter, your solar bill will vary by season — but your annual savings are comparable to what you’d see with a lease.
Compared to buying a system outright with cash, a PPA has some meaningful advantages. There’s no large upfront investment, and Palmetto owns and maintains the system throughout the agreement. That means if something needs attention, it’s Palmetto’s responsibility — not yours. You simply pay for the clean energy your panels produce, often at a rate lower than what you’d pay your utility. Learn more about how buying compares to leasing solar.
Palmetto’s LightReach program makes this easy for Cranston homeowners. With LightReach, you get solar panels on your roof with no upfront cost, predictable energy payments, and full system maintenance handled by Palmetto. It’s a straightforward way to start generating your own clean energy without the complexity of owning and managing the system yourself.
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!
