What is Smart Grid?

Smart grid is the application of various technologies such as advanced metering, communications, distribution and sub-station automation, controls software, and data analytics to the energy system.

The smart grid enables the two-way flow of energy and information between grid operators and energy consumers. It empowers consumers to actively manage their energy use (and distributed energy assets), supports grid operators to optimize how the system serves dynamic energy demands, and lays the foundation for future main-stream technologies such as distributed renewables, electric vehicles, energy storage assets, and the internet-of-things.

The smart grid brings additional functionality and understanding along the entire energy system – from major generation and transmission to the building and appliance level. The smart grid knits together various aspects of the new energy future from energy efficiency and demand response programs that maximize local energy resources and improve the health of the planet.
