A smart grid delivers electricity using digital technology.

A smart grid delivers electricity from suppliers to consumers using digital technology to save energy, reduce cost and increase reliability and transparency. Such a modernized electricity network is being promoted by many governments as a way of addressing energy independence, global warming and emergency resilience issues.
As with any heavily promoted initiative, many similar proposals have many similar names, including at least smart electric grid’, smart power grid, intelligent grid or intelligrid, FutureGrid and the more modern intergrid and intragrid.
In principle, the smart grid is a simple upgrade of 20th century power grids which generally ”broadcast” power from a few central power generators to a large number of users, to instead be capable of routing power in more optimal ways to respond to a very wide range of conditions.
