The site currently has chargers and plans to
scale 60, for combined nameplate charging capacity nearly 12
MW—enough charge 200 electric trucks per day. This increases the utilization

storage, and megawatt charging needs evolve. addition,
29 bobtail lanes feature 180-kW chargers, offering longer-term parking
and charging convenience for drivers while reducing deadhead miles. Each transformer feeds dedicated switchboard, which
distributes power each charger its group. First, the 180-kW chargers are disconnected; that doesn’t
