A ANEEL (National Electric Energy Agency) held, this Thursday (13), an international seminar on improving the regulation of energy storage in Brazil.
The event was attended by the general director of ANEEL, Sandoval Feitosa; the director of Electric Energy Studies at EPE (Energy Research Company), Reinaldo da Cruz Garcia; the director of the Department of Planning and Grants for Transmission and Distribution of Electric Energy and International Interconnections of the Ministry of Mines and Energy (MME), Guilherme Zanetti Rosa; and the manager of Southern Engineering at the National Electric System Operator (ONS), André Della Rocca Medeiros.
The seminar allowed a debate on experiences from different countries, such as Chile, Denmark, China and the United States, in the area of innovation and global energy challenges. Among the topics discussed were trends for international standards on Grid Forming; the integration of storage systems; solutions for energy resilience and technological innovation. The results of the R&D Project “Application of Battery Energy Storage (BESS) in the Brazilian System” were also presented.
“A ANEEL is here not to limit market development, but to encourage it. That is why we are discussing this new frontier that is opening up for the Brazilian electricity sector, which has been very well designed from a regulatory point of view, and is being conducted with broad dialogue between all stakeholders. I am certain that this approach will leave an immense and relevant legacy for the future of the electricity sector in Brazil”, he highlighted. Sandoval.
The meeting takes place amid discussions of the Public Consultation No. 39/2023, which proposes adjustments to the regulation to enable the integration of storage systems in Brazil. Despite the potential of these technologies, the country still faces regulatory uncertainties that may hinder their implementation, making the debate urgent and necessary.
Ricardo Tili, director of ANEEL, was also present at the event and classified the meeting as an opportunity for the Agency's technicians to interact with international experts and absorb knowledge about the best regulatory practices for the integration of batteries and other storage systems into the Brazilian electrical system.
“I was extremely happy to see our technicians from ANEEL interacting with international experts, exchanging and absorbing valuable knowledge about different battery integration experiences, global standards and opportunities for our system,” highlighted Tili.
“The exchange of knowledge with countries that have already made progress in this regulatory boundary It is essential for us to be able to develop robust, efficient, legally secure regulation capable of responding to the challenges of the growing insertion of intermittent renewable energy in our energy matrix”, he added.
The role of storage in the energy transition
Energy storage is a key component of the energy transition, enabling the stabilization of the electrical grid, more efficient use of energy generated by intermittent renewable sources such as solar and wind, and reducing the need to operate thermal power plants. Countries such as the United States, and Australia have already made significant progress in this area, developing regulatory mechanisms that allow the efficient insertion of these technologies into the energy market.
In Brazil, the topic is becoming increasingly relevant as the electricity grid becomes more dependent on variable sources. Through initiatives such as this seminar, Aneel seeks to understand how different regulatory models can be adapted to the national reality, ensuring legal certainty for investors and predictability for the electricity sector.
