Solar-Assisted EV Charging Update

  1. 1. Solar-Assisted EV Charging Update TDEC Conference Kingsport, Tennessee March 13, 2013
  2. 2. ORNL is DOE’s largest science and energy laboratory $1.65B budget World’s most intense neutron source 4,400 employees World-class research reactor 3,000 research guests annually $500M modernization investment Nation’s largest materials research portfolio Most powerful open scientific computing facility Nation’s most diverse energy portfolio Managing billion-dollar U.S. ITER project 2 Green Economy 1302
  3. 3. 3 Managed by UT-Battelle for the U.S. Department of Energy 3 Managed by UT-Battelle for the U.S. Department of Energy 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.
