Brazil’s electricity matrix is predominantly renewable, with hydro installed capacity totaling 61% 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 9% and 2% respectively of total installed

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:
