Well, Hy Vee is providing the electricity at the Peru supercharger, according to signage there. Despite being one of the newer models, it has significantly less amps than the (2013) supercharger in Rockford, even when I was the only one charging there.
I view their half-power ChargePoint charging stations as "enough to say that we're doing electric vehicle charging without actually costing us much money in electricity." I fret that the same thing will happen with "their" superchargers: a limited amount of electricity doled out to everyone waiting. And we won't know until the 3 ships and the midwest superchargers start being busy.
