America’s electrical grid was born more than a century ago, when our electricity needs were simple -- and our demand for power was much lower. As American homes and businesses take on ever-increasing numbers of electronic devices and technological capabilities, utilities need ways to learn about (and respond to) changing electricity demand in real time. The Smart Grid makes this possible, resulting in more reliable electricity for all grid users.

The Energy Department is investing in strategic partnerships to accelerate investments in grid modernization. We support groundbreaking research on synchrophasors, advanced grid modeling and energy storage -- all key to a reliable, resilient electricity grid that’s ready to power the generations ahead.
