How many biomass power plants are in Arizona?

3, with 33 MW of nameplate capacity between them, spread over 3 counties. That is the EIA-860M operating count for 2026-07.

Is there a map of Arizona biomass power plants?

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

Which is the largest biomass power plant in Arizona?

Novo BioPower Plant, at 27 MW. The table is sorted largest first, so the rest follow it.

Is there a biomass power plant near me in Arizona?

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 Arizona's biomass power plants?

No single ISO or RTO covers most of them. EIA files each plant against its own balancing authority, which in Arizona 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. Wood and wood waste, landfill gas, municipal solid waste and other waste biomass. 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.
