PULLMAN & COMLEY LLC TIMOTHY G. RONAN, ESQ. 850 Main Street – 8th Floor Bridgeport, Connecticut 06601 Attorneys for Defendants Hon. Anne M. Nardacci, United States District Judge: MEMORANDUM-DECISION AND ORDER I. INTRODUCTION On March 2, 2026, Plaintiff NuPower LLC (“NuPower”) commenced a state court action against Defendants Charter Oak Microgrid Holdco, LLC (“Charter Oak”) and NuPower Thermal, LLC (“NuPower Thermal”) in Albany County, New York, seeking a declaratory judgment and an order requiring Defendants to comply with their purported obligations under the parties’ Membership Interest Purchase Agreement (“MIPA”). See Dkt. No. 2. On March 26, 2026, Defendants removed this case to federal court pursuant to 28 U.S.C. § 1332 based upon diversity of citizenship. Dkt. No. 1. Presently before the Court is Plaintiff’s motion for a preliminary injunction, see Dkt. No. 7, and Defendants’ motion to dismiss the Complaint pursuant to Rule 12(b)(7) of the Federal Rules of Civil Procedure for failure to join a necessary and indispensable party. See Dkt. No. 8. For the reasons set forth below, Defendants’ motion to dismiss is denied and Plaintiff’s motion for a preliminary injunction is also denied.

II. BACKGROUND A. The Parties Both NuPower and NuPower Thermal are Connecticut limited liability companies, and Charter Oak is a Delaware limited liability company. Dkt. No. 2 at ¶¶ 5-7. Scale Microgrid Solutions, LLC is an affiliate of Charter Oak, see MIPA § 1.2, and Bridgeport Thermal Limited Liability Company, NuPower Thermal Bridgeport LLC, and NuPower Bridgeport FC LLC (“Bridgeport FC”) are wholly-owned subsidiaries of NuPower Thermal. Id. at § 1.114. B. Plaintiff’s Allegations On October 2, 2019, the Connecticut Public Utilities Regulatory Authority (“PURA”)

approved a Power Purchase Agreement (“PPA”) between the United Illuminating Company (“UIC”), a regional electric distribution company, and Bridgeport FC, for a transformative renewable energy project located in Bridgeport, Connecticut (“Project”), subject to certain conditions (the “Final Decision”). Dkt. No. 2 at ¶¶ 1, 14. Specifically, Bridgeport FC was required to submit an updated cost estimate and cost recovery proposal to PURA related to the interconnection portion of the Project, and UIC could not sign and execute the PPA until PURA made a determination regarding Bridgeport FC’s electrical interconnection cost responsibility and recovery. Id. at ¶ 14. On July 22, 2020, UIC submitted an Interconnection Facility Study Report to PURA, which estimated the interconnection portion of the Project to cost $10.23 million. Id. at ¶ 15. Then, on July 30, 2020, Bridgeport FC submitted an updated interconnection cost estimate and cost recovery proposal to PURA wherein Bridgeport FC proposed accepting an $8 million recovery cap on the cost of the interconnection portion of the Project, provided that Bridgeport FC be permitted to act

as the Engineering, Construction, and Procurement contractor, subject to UIC’s oversight. Id. at ¶ 16. PURA subsequently approved UIC’s Interconnection Facility Study Report, accepted the $8 million recovery cap on interconnection costs, and ordered UIC and Bridgeport FC to execute the PPA on October 28, 2020. Id. at ¶ 17. On February 2, 2024, NuPower and Charter Oak entered into the Membership Interest Purchase Agreement (“MIPA”), pursuant to which Charter Oak purchased all outstanding membership interests in NuPower Thermal from NuPower for a “Purchase Price” that included a “Development Fee.” Id. at ¶¶ 8-9, 18, 26. Section 2.4 of the MIPA provides that the Development Fee “shall be adjusted to reflect and take into account . . . [a]ny and all decisions from PURA

adjusting the cap for any additional electrical interconnection costs, if at all.” Id. at ¶ 27. Specifically, in the event that the interconnection costs increase above $8 million, and such additional costs are not “covered by the cost-of-service recovery mechanism set forth in the PPA,” under the MIPA, the Development Fee will be reduced by eighty cents for every one dollar of such costs, up to $4.8 million. Id. Additionally, under Section 2.4(b)(i) of the MIPA, if NuPower requests and directs that a petition be filed with PURA for approval to recover additional costs, including additional interconnection costs, Defendants are obligated to file such petition by or on behalf of NuPower Thermal, and support such petition. Id. at ¶ 28. On May 15, 2024, Bridgeport FC filed a motion to PURA for the approval of a revised interconnection cost estimate and cost recovery proposal, which PURA denied without prejudice. Id. at ¶ 19; see also Dkt. No. 11-1 at 14-20 (Bridgeport FC’s revised proposal to PURA seeking to increase the cap on interconnection costs to $15 million); Dkt. No. 11-1 at 22-24 (PURA’s denial of Bridgeport FC’s proposal without prejudice). Construction on the Project commenced in June 2025, and construction of the

interconnection portion of the Project commenced in January 2026. Dkt. No. 2 at ¶¶ 20, 22. Construction of the fuel cell energy generation portion of the Project is complete, except for the interconnection portion. Id. at ¶ 21. According to Plaintiff, the interconnection cost estimate that Bridgeport FC submitted to PURA, which resulted in the $8 million cost recovery cap, materially understated the costs to design and construct the interconnection portion of the Project, with the current estimate to complete the interconnection portion exceeding $18 million. Id. at ¶¶ 23, 25. The costs to design and construct the interconnection portion drastically increased due to factors beyond the parties’ control, such as late-stage design and construction changes required by UIC, rising material and labor costs due to the COVID-19 pandemic, and general inflation. Id. at ¶ 24.

Plaintiff alleges that it prepared a petition to reopen and modify PURA’s Final Decision for the limited purpose of requesting that PURA increase the interconnection cost recovery cap from $8 million to $17.5 million (“Proposed Petition”). Id. at ¶ 29. Plaintiff further alleges that Defendants breached the MIPA by refusing to file the Proposed Petition with PURA after repeated requests by Plaintiff. Id. at ¶¶ 30-31, 37-39. C. The Instant Motions On March 2, 2026, Plaintiff commenced this action in New York State Supreme Court in Albany County seeking declaratory and injunctive relief pursuant to the MIPA and in connection with the Project. See Dkt. No. 2. On March 26, 2026, Defendants removed this case to the Northern District of New York. Dkt. No. 1.1 On March 30, 2026, Plaintiff filed a motion for a preliminary injunction, seeking an order requiring at least one of the Defendants to immediately file and support the Proposed Petition with PURA, or cause Bridgeport FC to do the same. Dkt. No. 7. On April 13, 2026, Defendants opposed Plaintiff’s motion, contending that Plaintiff cannot satisfy the heightened standard

applicable to mandatory preliminary injunctions, see Dkt. No. 11, and Plaintiff replied in further support of its motion on May 8, 2026. Dkt. No. 16. On April 2, 2026, Defendants filed a motion to dismiss the Complaint pursuant to Rule 12(b)(7) of the Federal Rules of Civil Procedure
