Warwick Electricity Prices

Electricity in Warwick costs significantly more than the national average — and that gap has been growing steadily over the past few years.

Rhode Island’s electricity rate climbed from 22.3 cents per kWh in 2021 to 28.1 cents in 2024 — a roughly 26% increase in just three years. The national average over that same period rose from 13.7 to 16.5 cents per kWh.

Solar can help Warwick homeowners reduce their dependence on the grid. By generating your own electricity, you’re less exposed to rising utility rates that have consistently outpaced the national average in Rhode Island.

Over time, that protection adds up. Homeowners who go solar lock in more predictable energy costs — a meaningful advantage in a state where electricity rates have shown a persistent upward trend.

Warwick Area Utility Providers

In Warwick, RI, National Grid is the primary electricity provider. Based on 2023 data, National Grid customers pay approximately 27.2¢ per kWh — among the highest rates in the country.

To put that in perspective, the 2023 national average was 16.0¢ per kWh. Rhode Island’s state average was 27.00¢ per kWh — meaning Warwick residents pay roughly 70% more than the typical American household.

High electricity costs make solar worth a closer look. Generating your own power at home means relying less on the grid — and less exposure to rates that have steadily climbed over time.

Rhode Island Solar Incentives

Warwick homeowners have access to several solar incentives in Rhode Island that can help reduce the upfront and ongoing costs of going solar.

Rhode Island offers a mix of grants, tax exemptions, net metering credits, and battery storage rebates. These include the REF Small Scale Solar Grant, a sales tax exemption, a property tax exemption, and the ConnectedSolutions battery program — each with its own eligibility requirements.

Note that the federal residential solar tax credit is no longer available for new installations. If you’re considering a solar lease, Palmetto’s LightReach program handles the commercial tax credit and passes savings through lower monthly payments.

Incentive Type Description Source
Renewable Energy Fund (REF) Small Scale Solar Grant Rebate A state grant of $0.65 per watt (up to $5,000) for residential solar installations, with an additional $2,000 adder for battery storage systems installed at the same time. Learn More
Rhode Island Net Metering Program Net Metering Rhode Island’s net metering policy allows solar customers to earn bill credits at 80% of the retail electricity rate for excess energy exported to the grid, with protections guaranteed through 2039. Learn More
Rhode Island Solar Sales Tax Exemption Sales Tax Exemption Rhode Island exempts all solar PV equipment and installation labor from the state’s 7% sales tax, applied automatically at the point of sale. Learn More
Rhode Island Solar Property Tax Exemption Property Tax Exemption Rhode Island homeowners who install solar panels are exempt from any increase in property taxes resulting from the added value of their solar energy system. Learn More
ConnectedSolutions Battery Demand Response Program Rebate Rhode Island Energy’s ConnectedSolutions program pays battery storage owners $225 per average kW performed each summer in exchange for allowing the utility to dispatch their battery during peak demand events. Learn More
Affordable Solar Access Pathways (ASAP) Program Rebate A low-income solar lease program providing qualifying Rhode Island households in environmental justice areas access to affordable rooftop solar — currently paused and not accepting new applications. Learn More

Rhode Island’s Renewable Energy Fund (REF) Small Scale Solar Grant, administered by the RI Commerce Corporation, provides 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 — regardless of how many batteries are added. Grant rounds are offered in spring, summer, and fall each year on a first-come, first-served basis, and you must apply before installation begins.

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 will apply for the grant on your behalf. After installation is complete and final documentation (inspection certificate, interconnection agreement, and invoices) is submitted, payment is typically processed within 6–8 weeks, with a total timeline of 6–12 months from application to check.

Important: The REF grant is only available for net-metered systems and cannot be combined with the Renewable Energy Growth (REG) Program. However, it can be stacked with the state sales tax exemption, property tax exemption, and net metering credits. Homeowners in Warwick must choose between REF + Net Metering or the REG Program — not both.

Rhode Island’s Net Metering Program allows homeowners with solar panels connected to the grid to earn bill credits for excess electricity they send to the utility. For systems installed after April 15, 2023, Rhode Island Energy (which serves approximately 95% of RI customers, including Warwick) credits exported energy at 80% of the retail rate — currently approximately $0.232/kWh. Net excess generation credits are capped at 125% of your annual utility usage. Rhode Island law protects net metering terms through 2039, giving homeowners at least 13 years of guaranteed program access for a system installed in 2026.

Net metering can be combined with the REF Small Scale Solar Grant and state tax exemptions, but it operates under a separate framework from the REG Program. Homeowners in Warwick who enroll in the REG Program are not eligible for standard net metering credits on the same system. Virtual Net Metering (VNM) is also available for eligible entities such as municipalities, public schools, non-profits, and hospitals that cannot install on-site solar.

Rhode Island’s Solar Sales Tax Exemption waives the state’s 7% sales tax on all solar photovoltaic equipment and installation labor. Qualifying equipment includes solar panels, inverters, racking, wiring, solar batteries, and even electric vehicle (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 can be significant. On a typical residential solar system, the exemption can save homeowners over $1,900, and over $2,900 if a battery storage system is also included. Because the exemption applies to labor as well as equipment, the full installed cost of the system benefits from the tax relief.

This exemption is available to all Rhode Island homeowners installing solar and/or battery storage systems, including residents of Warwick, and can be stacked with other state incentives such as the REF grant, the REG program, net metering credits, and the property tax exemption. There are no income limits or application deadlines — the benefit applies to every qualifying solar installation in the state.

Rhode Island’s Solar Property Tax Exemption ensures that homeowners who install solar panels will not see their property tax bill increase as a result of the added value that solar brings to their home. Even though solar installations typically increase a home’s market value, the assessed value used for property tax purposes excludes the value of the solar energy system entirely. This exemption applies to both primary and secondary residences across Rhode Island, including Warwick.

Over the lifetime of a solar system, this exemption can represent substantial savings. On average, Rhode Island homeowners save over $7,200 in property taxes thanks to this exemption. The benefit is ongoing for as long as the solar system remains on the property, making it one of the most valuable long-term incentives available to RI solar owners.

No special application is required to claim this exemption — it is applied automatically when your property is assessed. This incentive can be freely combined with the REF grant, REG program, net metering credits, and the sales tax exemption, making it a seamless addition to any solar incentive strategy.

The ConnectedSolutions Battery Demand Response Program, administered by Rhode Island Energy, compensates homeowners with battery storage systems for allowing the utility to draw on their stored energy during periods of peak grid demand. Participants earn $225 per average kW performed each summer. 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. The program has received regulatory approval for the 2024–2026 period.

Popular batteries such as the Tesla Powerwall and Enphase IQ 10 are eligible for the program. Homeowners can lock in their incentive rate for the first five summers of enrollment, providing predictable earnings. Importantly, customers can participate in both the ConnectedSolutions Battery Program and the ConnectedSolutions Solar Program simultaneously, and doing so will not reduce the incentives earned in either program.

Low-income customers on the A-60 rate are also eligible for a 0% interest financing loan for the cost of a battery system, with no down payment required and a $25,000 lifetime cap per account. This program can be combined with the REF Energy Storage Adder ($2,000) for homeowners in Warwick installing solar and battery together, maximizing the financial return on a battery investment.

The Affordable Solar Access Pathways (ASAP) Program, administered by the Rhode Island Office of Energy Resources (OER) and the Renewable Energy Fund, was designed to provide qualifying low-income households in environmental justice communities with access to affordable rooftop solar through an innovative solar lease. The program targets households with incomes at or below 80% of the Rhode Island median income — for example, up to $35,674 for a single person or $68,605 for a family of four. Eligible geographic areas include parts of Woonsocket, Central Falls, Pawtucket, Providence, Cranston, West Warwick, East Providence, Warren, Middletown, and Newport.

Important Notice: The ASAP program is currently paused and not accepting new applications. The OER and the Renewable Energy Fund are reviewing next steps, including whether to identify a new program vendor to continue administering the program. Interested homeowners should monitor the official program page for updates on when the program may reopen.

When active, the program also offered eligible participants access to a zero-interest HEAT loan of up to $25,000 for the installation of a battery storage system. Rhode Island remains committed to expanding solar access for low-income residents, and updates will be posted to the official program page as they become available.

Leasing Solar Panels

If you’d rather go solar without a large upfront cost, Palmetto offers a Power Purchase Agreement (PPA) through its LightReach program for Warwick homeowners served by Rhode Island Energy (formerly National Grid). With a PPA, you pay only for the electricity your panels produce — at a set rate per kilowatt-hour — instead of buying the system outright.

With a cash purchase, you own the system and handle all maintenance yourself. With a LightReach PPA, Palmetto owns the system and takes care of maintenance, monitoring, and repairs. There’s no large investment to recoup, and your savings start as soon as your panels are active. Because solar panels produce more in summer than winter, your PPA payments will be slightly higher in summer — but your utility bill savings will be higher too, and annual savings are comparable to a fixed lease.

Curious how a PPA compares to buying outright? Learn more about the differences between buying and leasing solar to find the option that makes the most sense for your home and budget.

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!
