FAQ's

  1. What are UPPCO's on-peak hours?

    On the CP-RR plan (Large Light and Power Response Rewards), on-peak hours run from 7 AM – 11 PM on weekdays. All remaining hours are classified as off-peak.

  2. Does UPPCO charge more for electricity at certain times?

    Yes. UPPCO 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 2 active schedules; tou.tools does not publish pricing ($/kWh) details.

  3. How do I get UPPCO 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 UPPCO 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.
