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


Con edison smart grid strategy

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
