FAQ's

  1. What are SWEPCO's on-peak hours in Arkansas?

    On the AR-RTOU plan (Residential Time of Use (Schedule 41)), on-peak hours run from 3:01 PM – 7 PM and 5:01 AM – 11 PM every day. All remaining hours are classified as off-peak.

  2. Does SWEPCO charge more for electricity at certain times in Arkansas?

    Yes. SWEPCO offers time-of-use (TOU) rate plans where electricity costs vary depending on the period. The period—peak, off-peak, mid-peak, or super off-peak—depends on the time, day, and season. This page lists boundaries for 3 active schedules; tou.tools does not publish pricing ($/kWh) details.

  3. How do I get SWEPCO time-of-use periods in my app?

    Schedules are accessible programmatically via the tou.tools REST API and MCP server for AI agents. By querying a U.S. address or ZIP code, your application can instantly retrieve the current period and next scheduled transition time. Developer API keys are free.

  4. Do SWEPCO time-of-use hours change during holidays or seasons?

    Yes. Peak hours and rate periods can vary by season (typically summer and winter halves) and special holidays. While some schedules like E-ELEC keep stable hours year-round, others introduce super off-peak windows or adjust peak times. Check each rate plan card above for specific seasonal boundaries.

  5. What is the best time to charge an EV under SWEPCO's plans in Arkansas?

    For customers on EV-specific plans like AR-RS-PEV, the most cost-effective time to charge is during super off-peak or off-peak hours. Charging during these designated windows significantly reduces electricity costs and minimizes demand on the grid.
