1. Overview​

Rhode Island operates a deregulated electricity market structured around the separation of supply and delivery. The state's energy landscape is defined by a heavy reliance on natural gas, high retail electricity prices compared to the national average, and aggressive clean energy mandates. Rhode Island Energy (owned by PPL Corp.) serves as the primary utility, responsible for grid maintenance and delivery to approximately 780,000 customers, while residents and businesses can choose between the utility's "Last Resort Service" or competitive third-party suppliers 1.

As of 2024, in-state electricity generation is dominated by natural gas, which accounts for 87% to 92% of production. Renewable sources comprise approximately 13% of in-state generation, with solar energy representing the majority (70%) of renewable output. When considering retail electricity sales, wind and solar met roughly 20% of the state's demand in 2024 1. Despite this fossil fuel dominance, Rhode Island ranks as the second-lowest emitter of energy-related CO₂ emissions per capita in the nation, largely due to high energy efficiency and low per capita energy consumption 1.

The state has established some of the most aggressive decarbonization targets in the U.S. under the Act on Climate and the Renewable Energy Standard (RES). The state aims to offset 100% of electricity demand with renewable energy by 2033, with an interim goal of 34% by the end of 2025. Long-term targets include an 80% reduction in emissions by 2040 and reaching net-zero emissions by 2050 2. To support these goals, the state participates in the ISO New England (ISO-NE) regional grid and the Regional Greenhouse Gas Initiative (RGGI) 1. Key projects such as the Revolution Wind offshore farm (expected online late 2026) are central to this transition 1.

⚠️ Data Discrepancy: There is a conflict in the search results regarding the timeline for the 100% renewable energy goal. One source cites a target year of 2030 3, while another specifies 2033 4. The 2033 date aligns with the state's codified RES mandates, but the discrepancy requires verification.

2. Market Structure​

Rhode Island operates a deregulated electricity market established under the Utility Restructuring Act of 1996, separating power generation from delivery. This structure grants consumers "retail choice," allowing them to select a third-party competitive supplier for energy supply while the utility maintains the physical infrastructure for distribution 4.

Grid Operations and Wholesale Markets​

The regional high-voltage grid is operated by ISO New England (ISO-NE), which serves as both the Independent System Operator (since 1997) and Regional Transmission Organization (since 2005) for the six New England states. ISO-NE acts as the "air traffic controller" for the grid, manages wholesale electricity markets, and oversees long-term power system planning. While ISO-NE operates the system, transmission lines are owned by utilities but controlled operationally by ISO-NE. The organization is regulated by the Federal Energy Regulatory Commission (FERC), and Rhode Island's specific interests are represented through the New England States Committee on Electricity (NESCOE) 5.

Utility Landscape​

The state's utility landscape is dominated by a single large investor-owned utility (IOU):

  • Rhode Island Energy (RIE): A subsidiary of PPL Corporation (NYSE: PPL), RIE serves nearly 800,000 electric and gas customers. It acquired the business from National Grid in May 2022 6.
  • Municipal Utilities: The state includes smaller public entities such as the Pascoag Utility District (serving Pascoag and Burrillville) and the Block Island Utility District. Pascoag is noted for securing long-term fixed-rate agreements for nuclear and hydropower to offer lower rates 7.
  • Municipal Aggregation: Seven municipalities have pursued aggregation, collectively negotiating electricity rates for residents while utilizing RIE's infrastructure for delivery 8.

Retail Choice and Default Service​

  • Standard Offer: Consumers who do not select a competitive supplier are automatically placed on the utility's "Last Resort Service" (Standard Offer). These rates are approved by the Rhode Island Public Utilities Commission and fluctuate quarterly based on wholesale market costs 4.
  • Supply Mix: As of 2024, in-state generation relied heavily on natural gas, which fueled roughly 87% of generation, contributing to high energy costs persisting into early 2026 9.
  • Consumer Tools: The state provides the Empower RI website for residents to compare competitive offers against standard utility rates. There are typically no switching fees, and billing remains consolidated through Rhode Island Energy regardless of the supplier chosen 9.

Legislative Context (2025)​

As of early 2025, legislative proposals (e.g., H5161) have been introduced to study the feasibility of statewide municipal or cooperative ownership of utilities. Additionally, lawmakers have proposed bills to cap Rhode Island Energy's profit margin at 4% 10.

3. Clean Energy Policy​

Rhode Island mandates aggressive clean energy targets, primarily driven by the 2021 Act on Climate and the Renewable Energy Standard (RES). The state is legally required to achieve economy-wide net-zero emissions by 2050, with interim mandates including a 45% reduction in emissions below 1990 levels by 2030 [3].

Renewable Energy Standard (RES)​

Enacted in 2022 via House Bill 7277, the RES requires 100% of the state's retail electricity sales to come from renewable energy sources by 2033 [1][2]. This standard applies to all retail electricity providers, including investor-owned utilities and non-regulated power producers [1].

Compliance Targets: The RES mandates incremental annual increases in renewable energy usage, utilizing Class I (New) and Class II (Existing) renewable resources. Key targets include [1]:

  • 2025: 34% total
  • 2026–2027: Incremental 7% annual increases
  • 2028: Incremental 7.5% increase
  • 2033: 100% renewable energy

Providers comply primarily by purchasing and retiring Renewable Energy Certificates (RECs). An Alternative Compliance Payment (ACP) is available if procurement fails, set at approximately $78.24/MWh in 2024 [1].

Additional Mandates​

  • Energy Storage Systems Act (2024): Establishes a cumulative target of 600 MW of energy storage by 2033 to support grid reliability [2].
  • Heating Fuel Mandate: Requires all delivered heating fuel to contain at least 50% biodiesel by 2030 [2].
  • State Operations: State agencies are mandated to obtain 100% renewable energy for their own operations by 2025 [3].

Recent Developments and Proposed Changes (2026)​

In early 2026, Governor Dan McKee proposed significant modifications to these mandates to address rising utility costs, which are among the highest in the nation [2][3]. These proposals include [2][3]:

  • Timeline Delay: Pushing the 100% renewable electricity goal from 2033 to 2050.
  • Program Caps: A proposed $75 million cap on utility energy efficiency programs.
  • Transparency: New "Ratepayer Impact Notes" for major energy legislation.

Critics warn that these rollbacks may jeopardize the state's ability to meet the legally binding 2030 emissions targets established by the Act on Climate [2].

4. Utility Landscape​

Rhode Island's electricity market is served by one dominant investor-owned utility (IOU) alongside several smaller municipal and quasi-municipal utilities. The state operates as a deregulated energy market, meaning distribution companies (who own the wires) are distinct from competitive suppliers (who provide the actual energy) 4.

Investor-Owned Utility (IOU)

  • Rhode Island Energy (RIE): Formally known as The Narragansett Electric Company, RIE is the sole major IOU in the state. It serves approximately 99% of Rhode Island's electricity customers, totaling roughly 780,000 customers. The utility also provides natural gas to over 270,000 customers. Formerly operated by National Grid, RIE was acquired by PPL Corporation in May 2022 and rebranded 11.

Municipal and Quasi-Municipal Utilities

  • Pascoag Utility District (Clear River Electric and Water District): A quasi-municipal utility serving the Pascoag and Harrisville areas in the town of Burrillville with roughly 5,000 customers 12.
  • Block Island Power Company (Block Island Utility District): A non-profit, member-owned utility district serving New Shoreham (Block Island) 7.

Competitive Supply and Aggregation Under state law, customers can purchase power from third-party "nonregulated power producers" rather than the default "Standard Offer Service" 4. The largest competitive suppliers by residential sales volume include NextEra Energy (serving over 600,000 MWh), SmartEnergy Holdings, Clearview Electric, and Town Square Energy 13. Additionally, several municipalities participate in Community Electricity Aggregation programs, including Providence, Barrington, Central Falls, Newport, Portsmouth, South Kingstown, and Narragansett 14.

5. SSS-Eligible Resources​

No specific SSS-eligible resources identified. See section notes.

⚠️ Legislative Status: As of 2025, legislation (House Bill 5033) has been proposed to allow public utilities to purchase nuclear-powered electricity from neighboring states or permit future development of small modular reactors (SMRs) [RI.gov].

6. EAC/REC Registry Infrastructure​

Rhode Island utilizes the New England Power Pool Generation Information System (NEPOOL-GIS) as the primary registry for tracking Energy Attribute Certificates (EACs), specifically Renewable Energy Certificates (RECs) [1][2]. This regional system issues unique serial numbers for every megawatt-hour (MWh) of renewable energy generated in New England to verify origin, technology type, and vintage, preventing double-counting [3].

Administration and Compliance The Rhode Island Public Utilities Commission (PUC) manages the state's Renewable Energy Standard (RES) program through a portal administered by InClime, Inc. [2]. Obligated retail energy suppliers must submit annual compliance filings by July 15 each year to demonstrate they have met state-mandated renewable energy quotas [3]. To be valid for Rhode Island RPS compliance, RECs must be settled or retired within the NEPOOL-GIS system [1]. While RECs can be transferred from other systems like M-RETS, WREGIS, or PJM-GATS, their eligibility depends on specific state rules regarding out-of-region resources [1].

Generator Eligibility Facilities must apply for certification as an Eligible Renewable Energy Resource by filing a Renewable Energy Resources Eligibility Form with the PUC to have their RECs recognized for compliance [2]. Participants in the Renewable Energy Growth (REG) Program typically assign their REC rights to Rhode Island Energy, which acts as the aggregator within the NEPOOL-GIS system [2].
