For a greener and sustainable planet

REN has taken on the role of Issuer of Guarantees of Origin in mainland Portugal. It is responsible for implementing and managing the system for issuing certificates attesting that the source of that energy generation is renewable, including the electronic registration, issuance, transfer, and cancellation of these certificates.

REN is connected with the other European countries through the AIB – Association of Issuing Bodies, which facilitates the import and export of Guarantees of Origin within the European area. In Portugal, where over half the electricity consumed is generated from renewable sources, Guarantees of Origin play an important role in promoting the generation of renewable energy, “guaranteeing” a greener and more sustainable planet.

Guarantees of Origin help companies comply with their sustainability strategies, showing concern about climate change and contributing to the increased satisfaction of their employees and customers, while for domestic consumers it enables them to take on greater social responsibility and have a greater impact on the energy transition.
