Springerville Generating Station is a coal-fired power plant in Springerville, Arizona. It is owned by Tucson Electric Power (TEP) and has a generating capacity of 1765.8 MW. TEP announced in 2025 that it plans to switch the plant to a natural gas plant by 2030.
Read more on WikipediaThe Springerville Generating Station is a 1779.2 MW hybrid power plant located in Apache County, Arizona. The plant, which began operating in 1985, is owned by Fortis, a Canadian company, and operated by Tucson Electric Power Co. The primary fuel source is subbituminous coal (SUB), and the plant utilizes conventional steam coal technology in addition to solar photovoltaic generation. It is tracked as one of two plants in the state, and ranks 13th out of 75 plants nationally.
The Springerville plant operates within the Tucson Electric Power Company balancing authority and the Western Electricity Coordinating Council (WECC) NERC region. The latest annual generation data indicates an output of 5,549,274 MWh, resulting in a capacity factor of 35.6%. Financial data is available for the plant, sourced from lbnl_solar. The solar component of the plant uses a fixed tilt tracking system.

This plant's balancing authority participates in CAISO's Western Energy Imbalance Market (WEIM). Direct nodal pricing data is not yet available.
No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
