Prepa files changes to renewable energy, net metering

By on February 14, 2017

SAN JUAN – The Puerto Rico Electric Power Authority (Prepa) has filed before the State Department new rulings to interconnect generators and participate in net-metering programs that reduce requisites and simplify the evaluation process to interconnect the systems.

For the past few months, the renewable energy sector has complained about Prepa’s pace in complying with renewable energy interconnection parameters.

“We have developed some advanced rulings whose purpose is to reduce time and simplify the interconnection processes of the solar photovoltaic projects of residential and commercial customers to our electric grid, while reducing the costs of distributed generation systems with capacities between 1 [megawatt]  and 5 megawatts [MW]. With the new ruling, Prepa will help promote the development of distributed generation (DG) that use renewable energy sources,” Prepa Executive Director Javier Quintana said in a written statement Tuesday.

The new ruling consolidates three active rulings into two, apart from creating expedited processes to interconnect DG systems with capacities of up to 1 MW. It also integrates the evaluation, endorsement and approval into one stage for projects of less than 10 kilowatts [kW]. Likewise, it eliminates requisites to submitting blueprints, designs and inspection for the project’s approval, and limits the time Prepa has to conduct supplementary studies, to reprogram or replace meters, among other aspects.

For DGs with 25 kW or less capacity, Prepa eliminated the requisite to carry out periodic tests every five years, except for those recommended by the manufacturer. For DGs of up to 300 kW, the requisite to install a manual interruptor for Prepa’s operation was eliminated, and the need for a public liability responsibility policy. In addition, the meter’s relocation when not accessible to Prepa staff  was eliminated.

The modifications included in the rulings are expected to result in compliance to the standards established by the Puerto Rico Energy Commission and thus, should represent a positive impact for renewable energy systems.
