The Smart Grid can be described as the transparent, seamless and instantaneous two-way delivery of energy information, enabling the electricity industry to better manage energy delivery and transmission and empowering consumers to have more control over energy decisions.

Among the benefits of the Smart Grid are: improved grid reliability and security, fewer service interruptions, lower costs, cleaner energy, more integration of renewable energy, demand response opportunities and a means to bring greater energy independence to consumers.

Below are three interactive graphics showing how the grid currently works in The Grid Today, the future of power delivery in The Smart Grid and, lastly, how your household would work with the Smart Grid in The Smart Grid to You. Each shows how electricity reaches a consumer.

Moving your mouse over the images reveals an explanation of the elements of power delivery.

One significant difference between today’s grid and the Smart Grid is two-way exchange of information between the consumer and the grid. For example, under the Smart Grid concept, a smart thermostat might receive a signal about electricity prices and respond to higher demand (and higher prices) on the grid by adjusting temperatures, saving the consumer money while maintaining comfort.
