Docket Number SEC 26-005 Joint Petition of Nautilus Generation, LLC and Vistra Operations Company LLC for Approval of the Transfer of Ownership of Essential Power Newington, LLC Background On February 9, 2026, Vistra Operations Company LLC (Vistra) and Nautilus Generation, LLC (Natuilus); (collectively: 'Petitioners'), filed with the New Hampshire Site Evaluation Committee ('Committee', or 'SEC') requesting approval of the proposed upstream change of ownership of Essential Power Newington, LLC (EP Newington), whose ultimate corporate parent is Q-Generation Holdings, LLC, to Vistra. This filing (Petition) was made to the Committee pursuant to the statutory requirements of RSA 162-H:8 and RSA 162-H:5, I. Appended to the Petition was the Petitioners' Motion for Confidential Treatment, made pursuant to RSA Chapter 91-A, regarding: (1) the Audited Statement of Assets and Liabilities of Nautilus (Attachment 3 to the Petition); (2) certain portions of the unredacted Petition and included organizational charts (Attachments 1 and 2 to the Petition) that contain certain confidential financial information of the Petitioners that is not publicly available. On March 20, 2026, the Chairman of the Committee, Mr. Christopher J. Ellms, Jr. (Chairman, New Hampshire Public Utilities Commission), issued an acknowledgement of the Petition. The Petition and other information pertaining to this matter are available online at https://www.puc.nh.gov/VirtualFileRoom/Docket.aspx?DocketNumber=SEC%2026-005. Nature and Location of Certificate Facility The Committee granted the original certificate to EP Newington (then named Newington Energy, LLC) in May 1999. See SEC Docket No. 1998-01. The certificate was transferred three times, with the Committee's approval, in April 2008 (SEC Docket No. 2008-01), in June 2016 (SEC Docket No. 2016-02), and in November 2024 (SEC Docket No. 2024-04). EP Newington owns and operates a 606 megawatt combined-cycle, dual fuel merchant electric generation facility located in Newington, in Rockingham County, which has been in operation since 2002. The primary fuel of the facility is natural gas, and the secondary fuel is ultra-low sulfur distillate oil (i.e., diesel oil). A natural gas pipeline of the Portland Natural Gas Transmission System, and an oil transfer pipeline owned by Sprague Energy, serve the EP Newington facility. The Petitioners state that, upon Committee approval of transfer, Vistra will ensure that operation and maintenance of the EP Newington facility continues in compliance with all terms and conditions in the EP Newington SEC Certificate, with continuity in operational and maintenance capabilities, and adequate financial, technical, and managerial capability being exercised by Vistra.
