Balances From RGGI Auction Proceeds Must Be Returned To Ratepayers
On December 23, 2025 the Massachusetts Department of Public Utilities (DPU) ordered that the $39.85 million balance from RGGI auction proceeds be returned to ratepayers per state rule. Calculating an 80%/20% split based on Eversource’s and UI load shares, respectively, results in a total of $31.6 million to be returned to Eversource customers and $7.9 million UI customers. The utilities must incorporate the excess RGGI proceeds into their forthcoming Rate Adjustment Mechanism filings.

As background in DPU order in Docket No. 20-80, in 2025 and every five years thereafter, each utility must file a CCP by 4/1 and an informational Climate Act Compliance Term Report by June 2029. The plans must employ both five- and ten-year planning horizons in demonstrating how the utility proposes to:
- contribute to EEA’s prescribed Scope 1 and 3 GHG emission reduction sublimits;
- employ known technology to satisfy customer demand safely, reliably, affordably, and equitably;
- identify investment alternatives using pilot or demonstration projects;
- incorporate the evaluation of previous metrics; and
- implement recommendations for future plans.
