When is the cheapest time to charge an EV in Pennsylvania?
tou.tools tracks 1 EV-specific rate plan in Pennsylvania (RIDER-4-EV-TOU). On EV time-of-use plans the lowest-cost window is generally the overnight super-off-peak or off-peak period; charging then avoids the on-peak window. See the EV plan schedules for the exact hours.
-
How do I find which Pennsylvania utility serves a specific address or ZIP code?
tou.tools maps 1,560 Pennsylvania ZIP codes to the utilities that serve them. Because service territories can overlap, a ZIP may return more than one candidate utility; supplying a full street address resolves it to a single utility via a geocoded point-in-territory lookup. The REST API and MCP server both return the matching utility and its current TOU period.
