Brazil’s electricity matrix is predominantly renewable, with hydro installed capacity totaling 68% of the

total supply, while biomass, wind, SHPPs and solar account for 16%. In the next years, it is expected that

other sources will grow, mainly wind and solar, reaching 12% and 3% respectively of total installed

capacity in 2024.

Smart distribution was a key theme addressed by the Project

"Energy in the City of the Future"

• The smart grid technology will provide increased network monitoring capabilities and greater quality and commercial opportunities

• Smart Grids will boost the amount of information available, which will be used in innovative ways to optimize operations and services

Smart Grid | The Future of Distribution

Vision of the Future of Distribution is directly associated with Smart Grids:

• Reduced unnecessary travel;

• Shorter average service;

• Reduced SAIDI (optimization of possibilities of network maneuvering);

• Greater customer satisfaction (real-time information);

• Optimization of service to nearly 600,000 tickets every year.
