The Maine Supreme Judicial Court ruled on September 17, 2026, in the case of Berwick Solar, LLC v. Public Utilities Commission (PUC), affirming the PUC's decision to dismiss Berwick Solar's complaint against Central Maine Power Company (CMP). The court's ruling clarifies the obligations of solar energy developers regarding interconnection costs and the timelines for reconciliation statements. This decision impacts small solar energy companies and their financial responsibilities when connecting to utility systems.
In this case, Berwick Solar, a company focused on solar energy generation, entered into an Interconnection Agreement (IA) with CMP in March 2020. The IA was designed to outline the costs and responsibilities for connecting Berwick Solar's photovoltaic generation facility to CMP's electric distribution system. The dispute arose when CMP issued multiple reconciliation statements seeking additional costs for the interconnection, which Berwick Solar argued were issued outside the required timelines.
The PUC dismissed Berwick Solar's complaint in January 2025, stating that the company was still obligated to pay the actual costs of construction for the interconnection, regardless of the timing of the reconciliation statements. Berwick Solar appealed this decision, leading to the Supreme Judicial Court's review.
The court, led by Justice Lawrence, examined the relevant regulations and the IA. It determined that Berwick Solar's obligation to pay for interconnection costs was not contingent upon CMP's timely issuance of reconciliation statements. The court stated, "Berwick Solar’s obligation to pay the actual cost of its project is specified in section 3(A), which governs responsibilities for costs." This ruling emphasized that the failure of CMP to issue the statements within the specified time did not relieve Berwick Solar of its financial responsibilities.
The court also noted that the regulations provided mechanisms for addressing untimeliness, but Berwick Solar did not pursue these options. The ruling highlighted that the costs sought by CMP had actually decreased over time, suggesting that Berwick Solar was not prejudiced by the delays in receiving the reconciliation statements.
The court's ruling has significant implications for small solar energy developers in Maine. It reinforces the idea that companies must be diligent in understanding their contractual obligations and the timelines associated with interconnection agreements. By affirming the PUC's decision, the court has clarified that delays in utility communications do not exempt developers from their financial responsibilities.
Looking ahead, the ruling may set a precedent for future disputes involving interconnection agreements between solar developers and utility companies. It underscores the importance of adhering to established timelines and understanding the implications of regulatory frameworks governing interconnections.
Berwick Solar has the option to appeal the decision further, but details on any potential appeal were not available in the court filing. The outcome of this case may influence ongoing discussions about the regulatory environment for solar energy in Maine and beyond.
