Smart Grid & Demand / Response
What is the Smart Grid?
Use of digital information and controls to improve reliability, security and efficiency of the grid.
Use of smart automation systems that optimize the operation of buildings and homes.
Installation of smart meters to enable real time pricing
Deployment of demand / response

Auto Demand Response - a utility requests energy curtailment during an anticipated peak period where demand exceeds supply. Utility options are: Purchase power on the spot market Start up old generation plants Build new power plants (very costly) Rolling blackouts Demand / Response Auto DR is an automated way to achieve demand reduction.
