It depends on the plan. Of the 5 residential TOU plans we track in Arkansas, 2 apply on-peak periods every day including weekends, while 3 restrict on-peak to weekdays and treat weekends as off-peak. Many tariffs also treat observed holidays as off-peak; the Days column in each schedule above shows the exact rule.

Some do. Of the 5 residential TOU plans we track in Arkansas, 2 shift their period boundaries between seasons (typically summer and winter), while 3 keep the same hours year-round. Each schedule above lists its exact season dates.

tou.tools tracks 1 EV-specific rate plan in Arkansas (AR-RS-PEV). 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.

tou.tools maps 1,211 Arkansas 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.
