How PNM’s plans work
1A (Residential Service). In July the first 450 kWh a month cost 13.7¢ each; then 19.3¢ above 450 kWh a month, then 24.2¢ above 900 kWh a month. An average New Mexico home (942 kWh in July) goes past the first tier, so extra load such as an EV is priced higher. Fixed charge: $12.79 a month.
Prices on this page are all-in per kWh, before taxes: the totals recorded in the OpenEI Utility Rate Database, base rates plus the riders and supply charges it includes. Your bill shows them as separate lines, and riders can change between tariff revisions.
As a cross-check, PNM billed its residential customers an average of 16.35¢ per kWh in 2025 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for New Mexico’s price change since.
