Arizona Public Service: FAQ

How many power plants does Arizona Public Service operate?
EIA-860M lists 21 operating plants against “Arizona Public Service Co” for 2026-07, totalling 11 GW of nameplate capacity in 2 states.
Is Arizona Public Service the owner of these plants?
EIA-860M names one reporting entity per generator. That entity operates the plant on the survey; ownership can sit with a parent, a partnership or a tax-equity structure that the form does not record.
Why are affiliates listed separately?
Because EIA files them separately. Rolling subsidiaries into a parent would need an ownership map EIA-860M does not publish, so this page does not invent one.
