Solar-Assisted EV Charging Project

•  In August 2009, ORNL was awarded $6.8 million for the installation of solar-assisted EV charging stations in Tennessee. This was part of a larger DOE grant to Ecotality for the deployment of EV charging stations in five states

•  The grant to ORNL required a 50/50 cost share match from regional partners. The majority of the cost share has been, or will be met, by the State of Tennessee, TVA, EPRI, and Nissan.

•  The final part of the cost share match is the State of Tennessee project.

•  We have also enjoyed great partnerships and in-kind support from the cities, distributors, and universities with whom we have worked.
