The Connecticut Light & Power Company d/b/a Eversource Energy (“Eversource”), the Connecticut Green Bank (“Green Bank”), and The United Illuminating Company (“UI”; together with Green Bank and Eversource, the “Program Administrators” or “PAs”) submit to the Public Utilities Regulatory Authority (“PURA”) the attached compliance pursuant to PURA’s May 5, 2026 Motion Ruling No. 18 in the captioned docket (the “Motion No. 18 Ruling”).

The PAs are filing this compliance to update to the Energy Storage Solutions Program Manual to reflect the Motion No. 18 Ruling in response to the PAs’ Motion to Support Upfront Incentive Buyouts, as directed by PURA in the Motion No.18 ruling. Specifically, Ruling No. 18 states:

Finally, the Authority directs the Program Administrators to incorporate the approved upfront incentive buyback framework into the ESS Program Manual no later than May 19, 2026, rather than deferring such updates to the August 1 filing. The updated ESS Program Manual, including both clean and redlined versions, shall be submitted as a compliance filing in this proceeding.

As background on April 24, 2026, the Program Administrators filed Motion No. 18 requesting PURA to clarify the Authority’s December 17, 2025, Decision in Docket No. 25-08-05 and approve of a process to permit upfront incentive buyouts, whereby third parties may repay the outstanding portion of an upfront incentive to enable enrollment in the new Construct ESS Program design. This section is 3.8 entitled “Upfront Incentive Buyback and Transition to Construct 5 Option” in the Program Manual.
