Millions of smart meters have been installed across the country. Smart meters provide two-way communication between you and your utility, helping your utility know about blackouts, for example. This helps utilities to maintain more reliable electrical service.

Smart meters can be used with home energy management systems such as Web-based tools that your utility provides or devices that can be installed in your home. Smart meters can display your home energy use, help you find ways to save energy and money, and even allow you to remotely adjust your thermostat or turn appliances off.
