Miner installs Brazil’s largest battery storage system at Rio de Janeiro port

Diversified miner Vale is making further progress in its strategy of replacing fossil fuels, with the announcement this week that it is installing Brazil’s largest battery energy storage system (BESS) at a port in Rio de Janeiro to supply electrical demand.

The BESS at Ilha Guaíba terminal (TIG), being developed in partnership with Siemens and MicroPower Comerc will reduce the electric energy cost of the port by about 20% by substituting the electrical grid supply during peak demand periods when the tariff is more expensive.

The equipment has a storage capacity of 10 MWh.
