Some do. Of the 6 residential TOU plans we track in New Mexico, 2 shift their period boundaries between seasons (typically summer and winter), while 4 keep the same hours year-round. Each schedule above lists its exact season dates.

tou.tools tracks 1 EV-specific rate plan in New Mexico (NM-42). 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.

tou.tools maps 423 New Mexico 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.
