What Is the Rhode Island Renewable Energy Standard?

In 2022, Rhode Island passed one of the most aggressive renewable energy standards in the United States, mandating 100% renewable electricity by 2033. This aggressive timeline reflects the state's commitment to decarbonization and long-term clean energy procurement.

The RES Framework

Rhode Island's Renewable Energy Standard requires retail electricity providers and load-serving entities to supply an increasing percentage of their electricity from renewable sources each year. Compliance can be achieved through two primary mechanisms:

• NEPOOL-GIS Certificates (RECs): Tradeable renewable energy certificates that prove generation from qualifying renewable resources.
• Alternative Compliance Payments (ACP): A financial mechanism allowing suppliers to pay a fixed rate per MWh instead of procuring RECs if they are unavailable or cost-prohibitive.

The ACP serves as the safety valve for the program. If REC prices exceed the ACP rate in the market, suppliers can elect to pay ACP instead, effectively creating a ceiling price for compliance.

The Two-Tier Structure

Rhode Island's RES uses a two-tier framework that separates existing renewable generation from new renewable capacity. This structure helps balance cost predictability with the state’s aggressive push for new renewable development.

Existing RES (Baseline)

The Existing RES tier maintains a stable requirement for renewable facilities that were already operational before the state’s most aggressive expansion began. This tier:

• Requires approximately 16% of retail sales from existing renewable sources.
• Remains relatively stable year-to-year.
• Covers existing hydroelectric, wind, and other renewable facilities.
• ACP Rate: $72.00/MWh (CPI adjusted annually).

New RES (Aggressive Ramp)

The New RES tier is the real driver of the state’s decarbonization schedule and grows significantly each year:

• 2024: 9% of retail sales (total RES: 25%)
• 2025: 15% of retail sales (total RES: 31%)
• 2026: 22% of retail sales (total RES: 38%)
• 2027: 29% of retail sales (total RES: 45%)
• 2028: 36% of retail sales (total RES: 52%)
• Continuing to: 100% by 2033
• ACP Rate: $85.00/MWh (CPI adjusted annually).

The New RES requirement grows at approximately 6–7% per year, among the largest annual step-ups of any U.S. renewable mandate.

What This Means for Brokers

Rhode Island's RES creates meaningful pricing challenges for brokers and suppliers. Understanding these dynamics is critical to quoting competitively while preserving margin.

Supply Pricing & Procurement Strategy

• Rising REC Costs: RI supply pricing must reflect rapidly escalating REC procurement costs. As the New RES obligation ramps higher, availability tightens and prices rise.
• Multi-Year Exposure: A customer locked into a 3-year fixed deal in 2024 faces cumulative escalation risk. By 2026, the New RES requirement grows from 9% to 22% — a dramatic increase in that compliance layer alone.
• Annual Step-Ups: RI’s 6–7% annual step-ups are materially faster than Massachusetts, making this a critical variable in long-term pricing models.

Margin Protection Strategies

• Forward REC Procurement: Lock in REC pricing 1–2 years forward to reduce basis risk.
• Collar Pricing: Use optionality to cap downside exposure while preserving upside when REC markets soften.
• Annual Reset or Escalation Clauses: For longer-term deals, consider indexing annual compliance cost adjustments to ACP rates or REC benchmarks.

Customer Communication

RI customers need clear explanation of how fast compliance costs are growing:

• Show the ramp trajectory and explain that 2028 compliance costs can be roughly double 2024 levels.
• Explain the difference between Existing RES (stable) and New RES (rapidly escalating).
• Highlight Gridwealth’s REC procurement expertise — we manage the complexity so the customer doesn’t have to.
