The proposed Big Chino Valley Pumped Storage Project proposed by ITC Holdings Corp. (ITC) will serve as an integrated solution to modernize the Southwest’s energy infrastructure. This includes updating the region’s power grid to meet an evolving, uncertain energy future – a grid with the flexibility to accommodate diverse generation resources, changing market demands, increased challenges to forecasting of electricity supply and demand and ever evolving technology inputs.
The project involves a large-scale, closed-loop pumped storage hydroelectric facility, one powerhouse and two reservoirs covering 420 surface acres located in Yavapai County, Arizona. It also includes three connecting transmission lines. ITC has identified three preferred micro corridors and associated alternative segments for additional study and stakeholder review.
Eldorado Corridor: A 500 kV, approximately 145-mile line that connects to the existing Eldorado Substation
Peacock Corridor: A 500 kV, approximately 20-mile line that travels west to interconnect with the existing the Peacock Substation
Yavapai Corridor: A 500 kV, approximately 50-mile line that travels east to interconnect with the existing Yavapai Station
