tou.tools tracks 3 EV-specific rate plans in Indiana (IN-GS-PEV, IN-PUBLIC-FLEET-PEV, and IN-RS-PEV2). 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 Indiana utility serves a specific address or ZIP code?
tou.tools maps 329 Indiana 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.
