Rivian to install Waypoint chargers at all Tennessee Parks The Tennessee Department of Environment and Conservation (TDEC) announced a new deal with EV automaker Rivian to install Rivian Waypoint EV charging stations at Tennessee State Parks. The goal is to have charging stations available at all 56 state parks, depending on the availability of electricity. “Tennessee’s State Parks will be home to some of our very first Rivian Waypoints and at the forefront of our plan to provide accessible EV charging to those adventuring in America’s most beautifully preserved environments,” Matt Horton, executive vice president of Energy and Charging Solutions at Rivian, said.
