Why the “Smart GRID”?

  • ! Photovoltaic and Wind Power are getting more

efficient and lower cost – intermittent and unreliable

  • ! Electric vehicles are emerging – a mobile and large

new use for electricity

  • ! Customers want choices - to generate their own power

and buy power from others,local options

  • ! Electricity is increasingly vital to our personal,

economic and societal well being

  • ! The existing grid is aging and incompatible with these

changes

  • ! sectionalizing and reconfigures feeders

The ROUTER for the grid
