Frequently asked

  1. What are the typical time-of-use on-peak hours in New Hampshire?

    Across the 4 residential TOU plans tou.tools tracks in New Hampshire, the most common on-peak window is 4 PM – 8 PM (1 plan); others run 1 PM – 7 PM and 7 AM – 11 PM. Every hour outside the on-peak (and any mid-peak) window is billed as off-peak. Exact boundaries vary by utility and plan — see each utility's schedule above.

    tou.tools tracks 3 New Hampshire utilities with at least one active TOU rate plan — 12 active schedules in total. The largest by customers served are Eversource (New Hampshire), New Hampshire Electric Cooperative, and Unitil Energy Systems. They span investor-owned utilities and electric cooperatives. The full list above is sorted by customers served.

  3. Do New Hampshire time-of-use peak hours apply on weekends?

    On the residential TOU plans we track in New Hampshire, on-peak hours apply on weekdays only — weekends are off-peak across all 4 plans. Many tariffs also treat observed holidays as off-peak; the Days column in each schedule above shows the exact rule.

  4. Do New Hampshire time-of-use hours change by season?

    Not on the plans we track. All 4 residential TOU plans in New Hampshire keep the same period hours year-round. Each schedule above lists its exact season dates.

  5. When is the cheapest time to charge an EV in New Hampshire?

    tou.tools tracks 4 EV-specific rate plans in New Hampshire (EV-TD, TOU-EV-D, TOU-EV-G1, and TOU-EV-G2). 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.

  6. How do I find which New Hampshire utility serves a specific address or ZIP code?

    tou.tools maps 250 New Hampshire 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.
