MA RPS & APS Cost Summary

Plain-Language Primer: Understanding MA Compliance Costs

What You Need to Know

As a retail electricity supplier in Massachusetts and Rhode Island, Gridwealth Electric must comply with multiple state regulatory programs. These mandates require us to procure renewable energy certificates (RECs), alternative portfolio standards (APS) credits, and other clean energy resources. The cost of compliance is embedded in every kilowatt-hour we sell — and directly impacts your customer proposals.

This primer explains the six major compliance programs and how their costs stack up on a customer's bill.

1. Massachusetts Renewable Portfolio Standard (RPS) — Class I

What it is: The RPS Class I mandate requires retail suppliers to procure a growing percentage of electricity from new renewable energy sources: wind, solar, geothermal, and wave.

  • Compliance growth: Grows 2% per year through 2029.
  • 2025 requirement: 26% of all retail sales.
  • 2026 requirement: 28% of all retail sales.
  • ACP (Alternative Compliance Payment): $68.63/MWh.

Why it matters: Class I is the most expensive compliance obligation. A customer with 5,000 MWh annual usage requires approximately 1,400 MWh of Class I RECs in 2026, costing up to roughly $96,000 for the year at ACP.

2. RPS Class II Renewable

What it is: RPS Class II Renewable covers existing small renewable facilities already built, including small hydro, wind, and landfill gas.

  • 2025 requirement: approximately 3.41% of all retail sales.
  • 2026 requirement: approximately 3.57% of all retail sales.
  • ACP: $28.21/MWh.

Why it matters: Cheaper than Class I because facilities already exist. Still mandatory and adds meaningful annual cost to embedded compliance.

3. RPS Class II Waste Energy

What it is: RPS Class II Waste Energy covers waste-to-energy facilities and existing solid waste incineration.

  • 2026 requirement: approximately 3.70% of all retail sales.
  • ACP: $28.21/MWh.

Why it matters: Mandatory but generally lower-cost than Class I. Supply is constrained, so actual REC prices can fluctuate materially.

4. Alternative Portfolio Standard (APS)

What it is: The APS mandates procurement of electricity from alternative technologies including combined heat and power (CHP), advanced battery storage, flywheel storage, hydrogen fuel cells, and small wind.

  • Compliance growth: Grows 0.25% per year.
  • 2025 requirement: 6.75% of all retail sales.
  • 2026 requirement: 7.00% of all retail sales.
  • ACP: $28.21/MWh.

Why it matters: APS credits are less expensive than Class I but still represent a meaningful mandatory cost layer in every supply offer.

5. Clean Energy Standard (CES)

What it is: The Clean Energy Standard requires retail suppliers to procure electricity from clean or carbon-free sources including nuclear, large hydroelectric, new renewables (Class I), and other emissions-free resources.

  • 2025 requirement: approximately 80% of all retail sales.
  • 2026 requirement: approximately 82% of all retail sales.
  • ACP: approximately $30/MWh.

Why it matters: CES overlaps significantly with RPS. Many Class I RECs also satisfy CES, but suppliers often use nuclear and large hydro contracts to meet CES requirements cost-effectively.

6. Clean Peak Standard (CPS)

What it is: The Clean Peak Standard requires retail suppliers to procure a percentage of retail sales during seasonal peak hours from clean peak resources such as battery storage paired with solar and other peak-deliverable clean resources.

  • Compliance growth: Grows 1.5% per year.
  • 2025 requirement: 9% of sales during peak hours.
  • 2026 requirement: 10.5% of sales during peak hours.
  • ACP: $45/MWh (2025); $65/MWh (2026+).

Why it matters: CPS is the newest and fastest-growing compliance cost. The 2026 ACP jump to $65/MWh makes this program especially important in forward pricing.

Key takeaway for brokers: These six programs stack. A customer's total compliance cost exposure is the sum of all six programs. The calculator below shows this stacking and helps you understand what “embedded non-energy costs” really means in your supply quotes.

This represents the ceiling cost (ACP × obligation). Actual costs are typically lower depending on market conditions and REC availability.

Why the gap between ACP and actual cost? ACP is the safety-valve price. If a supplier cannot source enough RECs at market prices, it can pay ACP instead. Most of the time, actual REC market prices trade below ACP, especially for Class II and APS. Class I and CPS are more likely to approach ACP levels because of scarcity and policy prioritization.
