The “smart grid” is a hot topic these days: it’s in the press a lot, and gets tons of play in Washington D.C. However, the average citizen is still pretty hazy on the details.
Many people confuse the smart grid with smart meters; which are the smart grid’s most noticeable aspect, but only one piece of the puzzle. It’s all really pretty intuitive, once you see it on paper.
The term “smart grid” is an umbrella term, defining the modernization of the electricity infrastructure in the U.S. It will take a decade or more to fully revamp the grid with the latest technologies. It’s a project the Department of Energy (DOE) compares to the national interstate highway system and the Internet, both of which took decades to develop.
Our electricity grid includes several components: generation, transmission, distribution, and end consumption. Electricity storage is currently inefficient and costly, but storage may be a major component of the system in the future. The “grid” refers to the portion of the electricity infrastructure between the power plant and end-user: transmission, distribution, and storage.
