Avista Sun Car and Battery Storage Device Projects

Avista is currently testing the impact of two plug-in Toyota Prius hybrids that have been retrofitted with additional battery capacity to extend vehicle range with stored electricity. We are offsetting the demand these cars will have on our base load with renewable power we’re generating through solar panels installed on the roof of our corporate headquarters building. These solar panels are typical residential panels which are produced in our home state of Washington.


The purposes of this project include:

  • To educate employees, customers and the public on use of renewable, specifically solar power for residential use and for powering electric transportation; and
  • To test the impact to our system for power planning purposes as the public begins to adopt electric powered transportation, including implications of charging vehicles as part of smart grid planning.

We are also in the preliminary stages of testing a battery storage device for utility-grade power to assess the potential feasibility of shifting solar energy for better time of use.
