One of the main focuses of the agenda of the Minister of Mines and Energy, Alexandre Silveirawho has been in China for more than a week on an official trip, is to present to Chinese investors the Brazil’s first energy storage battery auctionscheduled for April, and attract companies from the Asian country to the event.
The initiative is considered a priority by the government, given the advancement of intermittent renewable sources in the Brazilian electrical system, such as solar and wind, and the need to guarantee security and stability in network operation.
This Friday (23), the minister met, in Shanghai, with representatives from Huawei. The main focus of the meeting was the debate on battery energy storage systems and the possible participation of Chinese companies in the auction that will be held.
The contest guidelines were also presented to CATL (Contemporary Amperex Technology), the largest battery manufacturer in the world. The meeting took place last Wednesday (21).
CATL occupies a central position in the global battery chain, supplying automakers such as Tesla, BMW, Volkswagen and Ford, as well as having a strong presence in large-scale energy storage projects.
The topic was also discussed in meetings with Envision Energy, a global leader in integrated solutions for the energy transition, and with representatives from the SANY Group, one of the largest industrial conglomerates in the world in the areas of heavy machinery, mining equipment, energy and infrastructure.
The battery auction, scheduled for April 2026, will begin supplying in August 2028 and will feature reserve power contracts lasting ten years. The competition will be aimed exclusively at contracting new energy storage systems.
In practice, the model will allow companies to install large batteries capable of storing electricity when there is excess on the grid, such as in periods of strong solar or wind generation, and releasing it at times of highest consumption.
The solution contributes to reducing the risk of blackouts, reducing dependence on thermoelectric plants and expanding the integration of renewable sources into the national electrical system.
Systems of this type are already widely used in countries such as the United States, China, Australia and members of the European Union, especially in networks with a high share of clean energy.
