Developer studies feasibility of 1,250-MW Arizona project

Arizona Independent Power Inc. of Sonoma, Calif., is studying the feasibility of developing the 1,250-MW Ford Canyon pumped-storage project in Arizona.

The Federal Energy Regulatory Commission granted Arizona Independent Power a preliminary permit to study the site. The developer will have until March 31, 2009, to study and gather site-specific information, prepare preliminary engineering plans, and define mitigation measures for environmental issues of the project.

Arizona Independent Power said it will use information obtained through the studies — expected to cost $5 million — to decide whether to submit a license application to build and operate Ford Canyon.

Frank L. Mazzone, president of Arizona Independent Power, said the project site is in White Tank Mountain Regional Park northeast of Phoenix.

Using water from the Colorado River system, the project could include: a 1,970-foot-long, 250-foot-tall earth and rockfill dam to impound an upper reservoir; a 2,160-foot-long, 210-foot-tall earth and rockfill dam to impound a lower reservoir; two 14,000-foot-long penstocks; a powerhouse with five 250-MW Francis-type pump-turbines and motor-generators operating under 1,180 feet average head; two tailraces; a 40-mile transmission line; and appurtenant facilities.

The project (No. 12630) could generate 1,682 gigawatt-hours a year. Electricity would be sold to utilities in Arizona and in the southwestern U.S., Mazzone said.
