1. As sustainable energy standards come into force, smart grid facilitates the integration of sustainable energy and smart meters are an indispensable part of the project.

2. Smart grid is about improving the efficiency of the system, or better demand management for utilities, too. That will lower operation costs of utilities, let alone staving off costly power outage.

3. It is also in the best interest of electricity utilities that EVs are going mainstream, namely, a big boon to utilities, thereby they need to put in charge stands where needed around highways, major roads with card readers or cell phone tech.

4. The vehicle-to-grid communication technology is helping the battery serve as a storage to prevent the costly blackout and preserve the power from sustainable energy. That means utilities are shedding cost for additional storage facilities and ratepayers are selling electricity during peak demand so that EVs can make more economic sense, as we know.
