Brazilian consultant CELA has said that the inclusion of electrical energy storage systems in a federal government capacity reserve auction, which could take place in June 2025, could strengthen Brazil’s National Interconnected System (SIN) network.
“By allowing the storage of renewable energy generated during times of lower demand, we will significantly reduce the effects of recurring cuts to solar and wind power generation, the so-called constraint-off (or curtailment), in addition to increasing of the system’s operational flexibility,” said CELA Chief Executive Officer Camila Ramos. “At the same time, the introduction of storage systems accelerates discussions on technical regulations, stimulates innovation in the sector and promotes the digitalization of Brazil’s electricity grid.”
The capacity auction would include contracts for energy storage projects with a minimum power availability of 30 MW for the equivalent of four hours of continuous transmission per day in the electrical system, with a maximum of one daily charge and discharge cycle, at a time determined by the National System Operator (ONS).
