The director of ANEEL (National Electric Energy Agency) Gentil Nogueira was drawn this Monday (13), to report on the processes relating to the first LRCAP (Auction for Reserved Capacity in the form of Power) intended for battery energy storage systems to be connected to the SIN (National Interconnected System).
He will be responsible for conducting the analysis of the two calls for bids scheduled for December and evaluating the respective rules that will govern the execution of the two competitions, both planned by the MME (Ministry of Mines and Energy) for the beginning of December.
Experience in planning and regulation.
Gentil Nogueira took office as director of ANEEL In September 2025, after serving as National Secretary of Electric Energy at the Ministry of Mines and Energy and being a member of the Board of Directors of the ONS (National System Operator).
His career encompasses experience in the areas of electricity sector planning, system operation, and public policy formulation. Since joining the Agency's board, he has participated in processes related to the oversight of distributors, corporate transactions in the generation segment, and regulatory improvements.
He also participated in the deliberation that approved the regulatory framework for energy storage systems, at which time he advocated for a more in-depth legal analysis of provisions related to reversible hydroelectric plants before the publication of the final regulation.
In their votes and statements in ANEELNogueira has also drawn attention to the need for the electrical system to incorporate mechanisms capable of increasing its operational flexibility, given the growing share of intermittent renewable sources.
Pioneering contest
According to the guidelines established by the MME (Ministry of Mines and Energy), the LRCAP (Laboratory for Recycling and Accelerating Production) for batteries, the first of its kind in the history of the electricity sector, will be divided into two sequential stages.
The first will be restricted to projects that meet the national content requirements, while the second will allow the participation of other ventures that are able to meet the technical conditions stipulated for the bidding process.
The rules defined for the auction establish, among other requirements, a minimum power of 30 MW per project, a discharge autonomy of at least four hours, a minimum overall efficiency of 85%, and the capacity to perform up to two complete charge and discharge cycles per day, with full recharge in up to six hours.
Market in anticipation
The implementation of the LRCAP storage agreement is being closely watched by the market as it represents the creation of a specific mechanism for contracting power supplied by battery systems.
Among the prospects associated with the auction is the use of this equipment to increase the operational flexibility of the electrical system, especially in light of the growing participation of wind and solar sources in the Brazilian energy matrix.
Storage is also seen as an alternative to reduce the effects of restrictions on the flow of renewable energy, allowing some generation to be shifted to periods of higher demand.
Another aspect that draws attention is the locational methodology developed by EPE (Energy Research Company) and ONS to identify the points in the network where storage systems can offer the greatest contribution to the electrical system.
The proposal aims to promote projects located in areas subject to congestion or operational restrictions in transmission.
At the same time, industry stakeholders are awaiting the final definition of the bidding documents to clarify aspects related to the tariff treatment of energy used for battery charging and the operating rules of these systems when dispatched by the ONS (National System Operator).
