What is a Smart Grid?
•“The electricity industry is poised to make the
transformation from a centralized, producercontrolled network to one that is less centralised
and more consumer-interactive.”
•“The Smart Grid will be characterized by two-way
flow of electricity and information and will be
capable of monitoring everything from power plants
to customer preferences to individual appliances.”
•“For utilities it is … the electricity network ..
Integrated with the latest advances in digital and
information technology to improve electricity system
reliability, security and efficiency.”
