Energy Bureau Resumes Interconnection Rulemaking
The Puerto Rico Energy Bureau has issued a Resolution and Order advancing its ongoing rulemaking to amend and modernize the regulatory framework governing the interconnection of distributed generation (“DG”) and microgrid systems. The proceeding, originally initiated in 2019 and later consolidated with a related 2018 case, builds on prior rounds of comments submitted in connection with the 2021 preliminary draft and subsequent proposals, including LUMA Energy’s recommendation to separate detailed technical requirements into a standalone Technical Interconnection Requirements (“TIR”) document.
The Resolution also reflects the material impact of House of Representatives Joint Resolution 193 of January 7, 2026 (“RC 193”), which mandates, among other changes, the elimination of certain interconnection-related charges for systems up to 25 kW and the repeal of inconsistent provisions in prior regulations. In response, the Energy Bureau has formally resumed its administrative process and established a structured pathway for stakeholder participation. Specifically, the Bureau has invited all stakeholders and interested parties to submit written comments addressing both (i) the substantive content and structure of the forthcoming interconnection regulation and (ii) the scope and priorities of the anticipated stakeholder workshops.
Further, although the TIR and Smart Inverter Settings are not formally part of the regulation, they are closely tied to the interconnection of DG systems; accordingly, the Energy Bureau invites stakeholder comments and discussion on the content of the TIR. All comments must be submitted no later than April 15, 2026, representing the key near-term opportunity for stakeholders to influence the regulatory framework. The Resolution further establishes a defined timeline for the rulemaking, including issuance of a draft regulation by July 7, 2026 and final adoption by January 7, 2027.
In addition to identifying priority topics for stakeholder input, such as technology scope, interconnection timelines and enforcement, application review processes, cost allocation, study standards, and queue management transparency, the Resolution prescribes specific procedural requirements for submissions.
Stakeholders must clearly title their filings “Comments on Proposed Generating Facility and Microgrid Interconnection Regulation – Case No. NER-MI-2019-0009,” address them to the attention of Chairman Edison Avilés Deliz, and submit them through one of the authorized channels: email (comentarios@jrsp.pr.gov), the Energy Bureau’s electronic filing portal, or by postal mail or in-person delivery to the Clerk’s Office in San Juan. These requirements, together with the planned workshop process and parallel technical evaluations (including ongoing review of smart inverter settings), underscore the Energy Bureau’s intent to develop a comprehensive and durable interconnection regime through a transparent, participatory, and procedurally rigorous process.
