Tennessee Valley Authority (TVA), provider of electricity to nine million people across seven southeastern states, will install revenue-grade electric vehicle (EV) charging stations in collaboration with selected distributors in its territory.
Installation of the charging stations is scheduled to begin in mid-2013. The solution includes ClipperCreek charging stations embedded with Itron sensor technologies, such as revenue-grade metrology, cellular communications and a ZigBee communication module.
With these charging stations, TVA can charge utility service vehicles while accurately measuring energy used. In addition, TVA can retrieve interval data collected at the charging station through a ZigBee smart meter interface.
The stations allow for flexible control of charging, receiving inputs (such as charging schedules and control signals for emergency demand response) from TVA, local distribution companies or local charging station operators.
