Frequently asked
-
What are the typical time-of-use on-peak hours in Ohio?
Across the 4 residential TOU plans tou.tools tracks in Ohio, the most common on-peak window is 2 PM – 6 PM (2 plans); others run 7 AM – 11 PM and 6 AM – 9 AM. Every hour outside the on-peak (and any mid-peak) window is billed as off-peak. Exact boundaries vary by utility and plan — see each utility's schedule above.

-
Do Ohio time-of-use peak hours apply on weekends?
On the residential TOU plans we track in Ohio, on-peak hours apply on weekdays only — weekends are off-peak across all 4 plans. Many tariffs also treat observed holidays as off-peak; the Days column in each schedule above shows the exact rule.
-
Do Ohio time-of-use hours change by season?
Some do. Of the 4 residential TOU plans we track in Ohio, 2 shift their period boundaries between seasons (typically summer and winter), while 2 keep the same hours year-round. Each schedule above lists its exact season dates.
-
When is the cheapest time to charge an EV in Ohio?
tou.tools tracks 2 EV-specific rate plans in Ohio (RS-PEV-OPT1 and RS-PEV-OPT2). 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 Ohio utility serves a specific address or ZIP code?
tou.tools maps 1,115 Ohio 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.
