FAQ's

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

    On the DCA plan (Large Data Service Rate — Schedule DCA), on-peak hours run from 1 PM – 7 PM and 4 AM – 10 AM on weekdays. All remaining hours are classified as off-peak.

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

    Yes. NES 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 14 active schedules; tou.tools does not publish pricing ($/kWh) details.

  3. How do I get NES 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 NES 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 NES's plans?

    For customers on EV-specific plans like EVC, 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.
