"Houston is sending an important message to its residents that alternative fuels are on their way, and the infrastructure to power these vehicles is available," he added.
Coulomb Technologies' networked charging stations, called ChargePoint Network, allow users to get text or e-mail messages when charging is complete. The network also provides a map of unoccupied charging stations and requires authenticated access to eliminate energy theft.
The charging stations are part of a program funded by Reliant Energy to highlight the use of plug-in electric vehicles. Reliant and Nissan signed a recent agreement to establish Houston as a launch city to advocate the use of electric automobiles by the U.S. public.
Reliant said that by adding a network of charging stations dedicated to electric vehicles, Houston could lead the way in zero-emission automobile usage.
