PSO's filed public-EV-charging schedule: time-of-use energy with no demand charge at all. Rates fold the 17.05% interim rate adjustment now in effect subject to refund — a rate-case final order is expected shortly and the library re-derives at the order — plus the fuel and class riders and Tulsa's franchise and sales taxes. The on-peak window runs 6 a.m. to 11 p.m. every day.
