Generating Facility and Microgrid Interconnection Regulation

An McV Energy Alert

July 28, 2021

On July 15, 2021, the Puerto Rico Energy Bureau (“PREB”) issued a Resolution and Order wherein it notified the joinder of case no. NEPR-MI-2019-0009 with case no. CEPR-MI-2018-0008. In case no. CEPR-MI-2018-0008, the PREB had ordered the Puerto Rico Electric Power Authority (“PREPA”) to adopt regulations to govern the interconnection of microgrid systems to PREPA’s grid. Meanwhile, the PREB opened case no. NEPR-MI-2019-0009 to address the process for the modification of the interconnection regulations and their alignment with public policy. The PREB deemed appropriate to deal with matters related to the interconnection of electrical systems to PREPA’s electric grid by consolidating both cases.

In the process of formulating and requiring modifications to the existing interconnection regulations, such as PREPA’s Regulation to Interconnect Generators to the Electric Distribution System of the Electric Power Authority and Participate in the Net Metering Programs, Regulation No. 8915, and PREPA’s Regulation to Interconnect Generators to the Electric Transmission and Sub-transmission System of the Electric Power Authority and Participate in the Net Metering Programs, Regulation No. 8916, the PREB published a single comprehensive interconnection regulation entitled “Generating Facility and Microgrid Interconnection Regulation.” Such document is intended to serve as a preliminary draft rule that would apply to any generating facility or microgrid seeking to interconnect to the electric power system, excluding only islanded systems.

The PREB is requesting input from stakeholders and interested persons before initiating rule making procedure by way of submittal of comments on the preliminary draft of the “Generating Facility and Microgrid Interconnection Regulation” with the intention to improve said draft before the formal rule making process commences. Comments are due on or before July 30, 2021.
