New Plant in Itajaí Strengthens the National Electricity Chain and Expands Production of Storage Systems to Boost the Energy Transition

WEG has confirmed the construction of Brazil’s largest battery factory. The new facility will be located in Itajaí (SC) and will have financing of approximately R$ 280 million from BNDES.

With this move, the company accelerates its expansion strategy in solutions related to the energy transition and decarbonization.

According to the company’s official statement, the project will raise production capacity to up to 2 GWh per year in energy storage systems (BESS). This volume is equivalent to approximately 400 systems of 5 MWh.

Energy Storage Gains Prominence in Brazil

Contrary to what many may think, the new factory will not produce batteries for electric vehicles at this initial moment. The company will direct the plant to stationary energy storage.

These systems stabilize electrical grids and allow for better utilization of renewable sources such as solar and wind.

In practice, the system stores energy generated during low demand periods and returns it to the grid when consumption increases.

Therefore, energy storage has become a key component following the regulatory auctions promoted by the federal government to unlock the sector.

Consequently, the greater the storage capacity, the greater the energy security of the country. Furthermore, the electrical system can better support the growth of electrification, including electric vehicles.

Thus, even without direct focus on electric mobility, the project indirectly influences the advancement of this market.

Automation, Technology, and Impact on the Production Chain

The new plant will have a high level of automation. The WEG will use mobile robots in internal logistics and will install a structure dedicated to testing and development.

Additionally, the factory will introduce technologies such as cell-to-pack architecture to Brazil. This solution improves efficiency and increases the energy density of battery systems.

Although production is focused on stationary storage, the local presence of advanced engineering strengthens the Brazilian industrial ecosystem.

In the short term, the direct impact on the automotive sector will still be limited. However, in the medium term, technological development may open up space for automotive applications.

The investment also reinforces Brazil’s position in the global decarbonization chain. Projects like this increase energy security and encourage the expansion of renewables.

In a scenario where the country begins to advance in local production of electric vehicles, the battery industry is likely to become increasingly strategic.

Therefore, WEG’s initiative represents not just industrial expansion. It signals a long-term vision and consolidates Brazil as a relevant participant in the battery economy.

Do you believe Brazil is prepared to become a leader in the global battery industry and in the energy transition?
