[Project No. 15030-000]


Desert Pumped Storage, LLC; Notice of Preliminary Permit 
Application Accepted for Filing and Soliciting Comments, Motions To 
Intervene, and Competing Applications

    On April 27, 2020, Desert Pumped Storage LLC, filed an application 
for a preliminary permit, pursuant to section 4(f) of the Federal Power 
Act (FPA), proposing to study the feasibility of the SilverKing 2 
Energy Storage Project (SilverKing 2 Project or project), a closed-loop 
pumped storage project to be located in Gila County, Arizona. The sole 
purpose of a preliminary permit, if issued, is to grant the permit 
holder priority to file a license application during the permit term. A 
preliminary permit does not authorize the permit holder to perform any 
land-disturbing activities or otherwise enter upon lands or waters 
owned by others without the owners' express permission.
    The proposed project would consist of the following: (1) A new 33-
foot-high dam with a total crest length of 9,780 feet, creating a 2,047 
acre-foot upper reservoir with a maximum surface elevation of 1,499 
feet above mean sea level; (2) two 3,329-foot-long, 10-foot-diameter 
steel penstocks that would connect the upper and lower reservoirs after 
passing through the powerhouse; (3) a new powerhouse to be located 
close to the afterbay with an approximate elevation of 1,210 feet above 
mean sea level with four 25-megawatt generator units with a total 
installed generation capacity of 100 megawatts and associated 
switchgear and controls; (4) an approximately 100-foot-long, 14-foot-
diameter tailrace low pressure draft tube between the powerhouse and 
the lower reservoir; (5) a new 98-foot-high dam with a total crest 
length of 3,273 feet, creating a 1,846 acre-foot lower reservoir, with 
a maximum surface elevation of 1,210 feet above mean sea level that 
will utilize an existing waste rock dump of an open pit mine; (6) a new 
200 mega-volt ampere (MVA) substation located adjacent to the lower 
reservoir; (7) an approximately 500-foot-long new 230-kilovolt 
transmission line from the new substation to the existing transmission 
lines owned by Salt River Project Agricultural Improvement and Power 
District; and (8) appurtenant facilities. The estimated average annual 
generation of the SilverKing 2 Project would be 400 gigawatt-hours.
