Platts discontinues several New York, Connecticut and New Hampshire US Renewable Energy Certificates assessments, May 4
Platts, part of S&P Global Energy, has discontinued several US Renewable Energy Certificates (RECs) price assessments, effective May 4, 2026.
Platts initially proposed the discontinuation on Feb. 5, as published in a proposal note followed by a decision note published Feb. 23, 2026.
- New York Tier 1 RECs have been discontinued due to regulatory changes that have reduced market liquidity.
- Connecticut REC Class 1 Prior Year Vintage and New Hampshire REC Class 1 Prior Year Vintage have been discontinued due to limited liquidity for these contracts.
Platts assessments for New York Wind RECs are not impacted by this change. Platts also continues to assess Connecticut REC Class 1 Current and Next Year vintages, and New Hampshire REC Class 1 Current and Next Year vintages.
The discontinued price assessments are as follows:
