Childs
Location: AZ
Operator: Arizona Public Service
Configuration: 3 X 1.8 MW
Operation: 1918 (ret 2005)
T/G supplier: ??
Quick facts: In 1976, the Childs-Irving hydro complex was named the 11th ASME National Historic Mechanical Engineering Landmark. The project was cited for innovations in design and construction including steel transmission towers, forged penstocks, and the use of mule teams to move components to the remote sites on Fossil Creek in the Mogollon Rim country. The projects were initiated to support regional mining activities. In 1991, APS filed FERC relicensing applications for the Childs-Irving complex, but, after lengthy discussions with other stakeholders, APS announced in 1999 that it had decided to decommission the Childs-Irving plant and restore full flow at Fossil Creek. In Jul 2010, APS completed the 5yr, $11mn decommissioning project.
