FAQ's

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

    On the SC12 plan (Residential Service with Time-of-Use Metering (SC No. 12)), on-peak hours run from 10 AM – 6 PM and 7 AM – 10 AM and 5 PM – 10 PM on weekdays. All remaining hours are classified as off-peak.

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

    Yes. NYSEG 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 NYSEG 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 NYSEG 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.
