  7. Traditional grid structure Future grid structure The Utility of the Future Solar PV Smart building technology Sensors and monitoring Electric vehicles Sensors and monitoring Customer-sited generation Customer-sited generation • Customers receive electricity • Dedicated networks with limited resources • Grid as a sole source • Real-time data/control • Customers receive/feed electricity • Networks with shared assets and layered customer resources • Grid as a sole source, back-up, and two-way flow • Increased real-time data/control

  8. Con Edison Smart Grid Strategy Distribution Automation 82% • Expand T&D Smart Grid technology with proven benefits • DOE Stimulus Smart GridInvestment Grant Projects • Continue to develop / demonstrate emerging Smart Grid technologies with less certain benefits • DOE Stimulus Smart Grid Demonstration Projects 8

  9. Smart Grid Investment Grant Flushing Network • Installation of underground autoloop and underground wireless controlled switches • Reduces severityand likelihood of a network event • Increases flexibilityduring contingencies Sub - Network A Sub - Network C Sub - Network B Substation 9
