PURA Issues Final Decision in Reconsideration of Yankee Gas Rate Case

(New Britain, CT - March 11, 2026) - The Connecticut Public Utilities Regulatory Authority (PURA or Authority) today issued an adjusted Final Decision in the Yankee Gas Services Company d/b/a Eversource Energy(Yankee or Company) rate case.

The Company originally sought approval of an approximate $209 million increase in November 2024, which was later amended to approximately $193 million, to which PURA issued a Final Decision the following November allowing for an increase of approximately $83 million. Today's decision modifies that amount to approximately $87 million, authorizing approximately 45% of the Company's request.

Following careful reconsideration of the record, consistent with the law, today's order revises the allowed revenue requirement for Yankee, which was determined in November 2025, from $802.24to $806.66 million, an increase of 0.551%.This amount reflects a refund to ratepayers of $40.22 million over the next three years.The company initially requested a revenue requirement of $912.95 million. The approved rate base was adjusted from $2,309 millionto $2,310 million, an increase of .002%. The base authorized rate of return on equity was maintained at 9.48% from the October order.

In reconsidering the November 2025 decision, the Authority maintained cost disallowances related to incentive compensation and inspection fees and maintained a cap on cost recovery for distribution integrity management.

The Authority also adjusted the gross earnings tax calculation and maintained the previously allowed expense for environmental remediation, while permitting a capped amount of deferred expense,grounded in advocacy from DEEP. Based on the record in this case and prevailing policy,the Authority removed return penalties related to record management, procurement, accounting, and documentation practices, but will continue to closely monitor the company's performance in these areas.
