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:
