RamaFlux Sierra PSH, LLC; Notice of Preliminary Permit Application Accepted for Filing and Soliciting Comments, Motions To Intervene, and Competing Applications

On April 30, 2026, RamaFlux Sierra PSH 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 Fish Creek Pumped Storage Project (Fish Creek Project or project). The proposed facility would be a 750-megawatt (MW) closed-loop pumped storage hydroelectric facility located near the town of Nevada City in Nevada County, California. 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 new facilities: (1) an ( printed page 62728) upper reservoir created by a new embankment at an approximate elevation of 4,200 feet above mean sea level to serve as the upper pool; (2) a lower reservoir created by a new embankment with at an approximate elevation of 2,600 feet above mean sea level to be located on the eastern slope of the Fish Creek drainage basin to serve as the lower pool; (3) a conduit system of steel-lined penstocks with a concrete and steel-lined pressure shaft to connect the upper and lower reservoirs to the powerhouse; (4) an underground powerhouse with reversible pump-turbine units with a generation capacity of 750 MWs located adjacent to the lower reservoir on its western side; (5) an intake structure at the lower reservoir; (6) a new single-circuit 230 kilovolt (kV) transmission line to connect the powerhouse to the existing 230 kV transmission infrastructure at the vicinity of the proposed project; (7) construction access routes; and (8) appurtenant facilities.
