The system built by Vale at the terminal in Rio de Janeiro is part of the investment of around US$ 2 billion, to reduce its emissions by 33% by 2030

Vale is installing, in Rio de Janeiro, one of the largest battery energy storage systems to supply the country's electricity demand. Recently, the company announced an investment of at least US$ 2 billion to reduce its absolute direct and indirect emissions by 33% by 2030, based on the premises of the Paris Agreement, in addition to the intention to become carbon neutral in 2050.

For the installation of the system, Vale entered into a partnership with Siemens and MicroPower Comerc (MPC), which in practice will reduce the cost of energy in the port by around 20%, by replacing the electricity supply from the concessionaire at peak demand times, when the tariff is more expensive. The equipment has a storage capacity of 10 megawatt hours, enough to serve 45 homes for one hour.

Vale reported that this type of technology is an important step in the company's decarbonization strategy. The use of batteries is one of the technologies that should be applied to replace diesel with renewable electricity in transport equipment, such as locomotives and off-road trucks, included in the Power Shift program, which is being implemented by the company.

“As Vale continues to decarbonize its operations, the use of batteries will become an increasingly important part of the electrification of our equipment fleet,” explains Vale's Director of Energy, Ricardo Mendes. “This project allows us to field test a new technology to accelerate Vale's energy transformation, which aims to achieve self-sufficiency by increasing electricity generation mainly through solar and wind sources in addition to our hydroelectric generation”, he adds.
