Yes — the map above. Each dot is one hydroelectric power plant, sized by nameplate capacity and placed at the coordinates EIA files for it.

Which is the largest hydroelectric power plant in New Mexico?

Navajo Dam, at 30 MW. The table is sorted largest first, so the rest follow it.

Is there a hydroelectric power plant near me in New Mexico?

The county roll-up below groups every plant by county, which is the quickest way to find the one closest to a given town.

Which grid operator runs New Mexico's hydroelectric power plants?

No single ISO or RTO covers most of them. EIA files each plant against its own balancing authority, which in New Mexico is largely a vertically integrated utility rather than an organised market.

How current is this, and what is left out?

EIA-860M for 2026-07. Conventional hydroelectric. Pumped storage is counted separately. Plants below 1 MW are not surveyed by EIA and so are absent; retirements and additions after 2026-07 arrive with the next monthly release.
