In this section you will find answers to frequently asked questions compiled by the Puerto Rico Energy Bureau.

What does Act 57-2014 represent for the electrical industry in Puerto Rico?

By adopting the Act 57-2014, as amended, known as the Puerto Rico Energy Transformation and RELIEF Act the legislature made changes to various laws and adopted new measures to promote a comprehensive reform of the electrical sector. In short, the purpose of the new legal framework is to ensure that the electrical system of Puerto Rico is efficient, that the power grid is stable and secure and that the electrical service has a fair and reasonable cost.

What is the Puerto Rico Energy Bureau and how does it work?

The Puerto Rico  Energy Bureau (PREB) is an independent and specialized public entity created by the Act 57-2014 , as amended, to serve as a key component for full and transparent implementation of the energy reform. Specifically, the PREB has the responsibility to regulate and supervise the electrical industry, to oversee adjudicative cases and disputes and to enforce the energy public policy of the Government of Puerto Rico.

The PREB works as a collegial forum that consists of one (1) Chairman, Edison Avilés Deliz, Esq., and four (4) Associated Commissioners, of which currently three (3) have been appointed, Ángel R. Rivera de la Cruz, Esq., Lillian Mateo Santos, Esq. and Ferdinand Ramos Soegaard, PE.

Entities that are operated an/or regulated by the PREB?

The Puerto Rico Energy Bureau (PREB) does not operate any entity within the industry, as this would involve a conflict, since the PREB is in charge of regulating, overseeing and supervising the members of the electrical industry in Puerto Rico, for example, the  Puerto Rico Electric Power Authority, and other private companies that produce energy.

What are the functions of the Puerto Rico Energy Bureau?

The functions of the Puerto Rico Energy Bureau (PREB) can be summed up in three main tasks: (i) to regulate, (ii) to investigate and (iii) to adjudicate. When the PREB issues regulations it is exercising its regulatory powers. Through this power, it sets the standards to be met by the companies offering electricity services in the country and the entities that make up the industry.

The PREB exercises its power to do research in order to: (i) collect information needed to perform its functions or (ii) to guarantee that persons or entities within the electrical industry are complying with the laws and regulations governing the industry.

Finally, the PREB exercises its adjudicative power to solve cases and controversies related to the energy sector. For example, the PREB is responsible for reviewing the determinations of electric power companies on electricity bills, to address complaints related with the failure of compliance with the Government’s energy public policy, to address complaints related with the failure of compliance of the Puerto Rico Electric Power Authority (PREPA) with the mandates established in Act 83-1941, to address complaints related with wheeling or interconnection, as well as cases and disputes related to contracts between PREPA and independent power producers.

Electricity rate and bill, are they the same?

No. The electricity rate is the amount the power utility company is authorized to charge the customer for the provided service. On the other hand, the bill is the document containing the detailed account of each of the charges the customer pays for the service received in a given period of time.

Does the Puerto Rico Energy Bureau determine my electricity invoice?

No. The electricity bill is determined by the power company. Now, the Puerto Rico Energy Bureau has the power to evaluate and approve rates for electric service proposed by the Puerto Rico Electric Power Authority and/or other electric utilities, so that they are fair and reasonable for consumers.

Does a power company need a permit to provide its services in Puerto Rico?

Yes. All the energy companies in Puerto Rico must request and receive a certification from the Puerto Rico Energy Bureau to provide services in the island.

For more information about this certification visit our Regulations Section and please download the Regulation on Certification, Annual Fees and Operational Plans for Electric Service Companies in Puerto Rico, Regulation 8701 of the Puerto Rico Energy Bureau. Or you can also visit our Documents and Payments section for additional information.

If I have a complaint related with my bill, who do I contact?

The Puerto Rico Energy Bureau (PREB) issued its Regulation on the Procedure for Bill Review and Suspension of Electric Service Due to Failure to Pay, which details the steps to follow by the client in case any objection to the electric bill arises.

On the other hand, under Act 143-2018, known as the Just, Reasonable and Transparent Billing of Essential Public Services in Emergency Situations; and Articles 2 and 3 of Act 3-2018, the PREB issued the Regulation on the Procedure for the Revision of Bills Issued by the Puerto Rico Electric Power Authority during Emergency Situations. This Regulation has the purpose of addressing the special cases in which an Emergency Situation occurs and the electricity service is not available for a certain period of time for the client, but an electricity bill for said period is received by the client.

For additional information, please contact the PREB Clerk’s Office.

Where do I have to go to file a complaint against a company regulated by the PREB?

To file complaints or appeals to the Puerto Rico Energy Bureau examine the relevant provisions of Regulation 8543, known as the Regulation of Adjudicative, Notice of Non Compliance, Rate Review and Investigation Procedures of the Puerto Rico Energy Bureau, as well as the Administrative Order on Instructions for Submitting Forms, Documents and Hearings, CEPR-MI-2015-0001, and submit the corresponding documents at the PREB Clerk’s Office, located at World Plaza Building, 268 Ave. Muñoz Rivera, Suite 202, San Juan, PR.
