Smart Grid

What is Smart Grid?

A “smart grid” is an electric power delivery system from point of generation to point of consumption integrated with advanced communications and information technology. Integrated solutions and analysis tools to optimize resources & costs and enhance reliability and system efficiency.

Smart Grid

What is Smart Grid?

NEMA (National Electrical Manufacturer’s Association) defines Smart Grid as ‘the addition of monitoring, analysis, control and communication capabilities to the national electrical delivery system to maximize the throughput of the system while reducing energy consumption’

Definition
