BATTERIES TO INTERUPT STORAGE MARKET

BRAZIL’S POWER SECTOR STARTED A SIGNIFICANT INVESTMENT CYCLE IN
2009, WHICH REACHED ITS APEX IN 2012, WITH THE CONSTRUCTION OF LARGE
HYDROELECTRIC PLANTS IN BELO MONTE, SANTO ANTÔNIO AND JIRAU IN THE
NORTH OF THE COUNTRY. NOW IT’S TIME FOR ENERGY STORAGE.

Brazil's power consumption has increased at a rate of 1.6% per the ability to ensure security of supply and stability — through
