Warwick Electricity Prices
Electricity in Warwick costs more than most of the country — and rates have been rising steadily for years.
Rhode Island’s electricity rate climbed from 22.3 cents per kWh in 2021 to 28.1 cents in 2024 — a 26% increase in just four years. The national average in 2024 was 16.5 cents per kWh.
Solar panels generate electricity from sunlight, which means Warwick homeowners can reduce how much power they pull from the grid — and lower their exposure to these rising utility rates.
Over time, solar can help stabilize your energy costs. Rather than paying whatever the utility charges each year, you’re generating your own power — giving you more predictability over your monthly bills long term.
Price of Energy: Rhode Island vs National Average
Warwick Area Utility Providers
In Warwick, RI, electricity comes primarily from Narragansett Electric. Based on 2023 data — the most recent available — Narragansett Electric customers paid about 27.2¢ per kWh, just above Rhode Island’s state average of 27.0¢ per kWh.
Both figures are significantly higher than the 2023 national average of 16.0¢ per kWh. New England’s heavy reliance on natural gas for power generation, aging grid infrastructure, and regional transmission costs all contribute to elevated electricity rates in the area.
When local electricity costs this much — nearly 70% above the national average — generating your own power at home through solar panel installation in Warwick, RI can make a meaningful difference in your monthly energy budget.

Rhode Island Solar Incentives
Warwick homeowners have access to several solar incentives in Rhode Island — including grants, tax exemptions, and utility programs — that can meaningfully reduce the cost of going solar.
These incentives include the Renewable Energy Fund grant, net metering bill credits, a 20-year property tax exemption, a full sales tax exemption on equipment and labor, and performance-based payments through the Renewable Energy Growth program.
Note that the federal 30% residential tax credit was eliminated by the Big Beautiful Bill. Homeowners who lease through LightReach may benefit indirectly, as Palmetto applies the commercial ITC and passes savings through 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 |

| 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, residents of Warwick 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, homeowners in Warwick 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 Warwick homeowners 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 Warwick 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 Warwick 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 in Warwick, 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
If you’re interested in solar but not ready to pay the full cost upfront, Palmetto offers a Power Purchase Agreement (PPA) through its LightReach program for Rhode Island Energy customers in Warwick. With a PPA, you don’t own the system — Palmetto does. Instead, you simply pay for the solar electricity your panels produce at a set rate per kilowatt-hour (kWh), rather than a fixed monthly amount.
Because solar panels produce more energy in summer than winter, your PPA payments will naturally shift with the seasons — higher in sunny months, lower in winter. Over the course of a year, the average cost tends to be consistent. And since Palmetto owns and maintains the system, you’re never responsible for repairs or upkeep. Want to understand how a PPA compares to buying outright? This guide breaks it down clearly.
Compared to a cash purchase, a PPA means no large upfront investment, no maintenance responsibilities, and predictable energy costs from day one. Palmetto also backs LightReach with a 90% production guarantee, so you can feel confident your system is working as expected. For Warwick homeowners served by Rhode Island Energy’s net metering program, a PPA can be a straightforward way to start saving on electricity without taking on the full cost of ownership.
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!

Yes, solar makes strong financial sense for Warwick homeowners. Rhode Island has the 5th highest electricity rates in the nation at 28.1¢/kWh — nearly 70% above the national average. With 4.7 peak sun hours daily, a typical Warwick home can save around $100,000 over 25 years, with a payback period of roughly 7–8 years. Rhode Island also offers a cash grant up to $5,000, net metering, and property and sales tax exemptions.
If upfront cost is a concern, Palmetto’s LightReach solar lease removes that barrier entirely — Warwick homeowners can go solar with no money down and start saving from day one, with Palmetto handling all maintenance.
Yes, Warwick homeowners served by Rhode Island Energy (formerly National Grid) have access to net metering. Under Rhode Island’s program, excess solar energy you send to the grid is credited on a 1:1 basis against your monthly consumption. Any remaining credits roll over month to month as a dollar credit indefinitely.
As of February 2024, customers can also request a cash payout of unused credits at the Last Resort Service supply rate, or transfer credits to another account under the same owner. Rhode Island law protects net metering access through 2039.
Yes, solar panels can increase your home value in Warwick. According to a Zillow study, homes with solar panels sell for approximately 4.1% more than comparable homes without them. For a typical Warwick home, that could mean tens of thousands of dollars in added resale value.
Rhode Island also offers a 20-year property tax exemption on the added value solar brings, meaning your property taxes won’t increase — you get the home value boost without the tax consequence.
