**Posted:** October 02, 2026
**Respond By:** November 30, 2026
**Identifier:** P-15429-000

FERC is considering an application to study the proposed Fish Creek Pumped Storage Project in Nevada County, California; this is a hydroelectric permitting notice, not a purchase of goods or services.
- Government buyer: Federal Energy Regulatory Commission (FERC), within the U.S. Department of Energy; no specific office is identified.
- Applicant: RamaFlux Sierra PSH, LLC. No equipment OEMs or other vendors are identified.
- Proposed project: One 750-MW closed-loop pumped-storage hydroelectric facility, identified as project P-15429-000, near Nevada City.
  - Includes new upper and lower reservoirs formed by embankments, steel-lined penstocks, a lined pressure shaft, and an underground powerhouse with reversible pump-turbine units.
  - Also includes a lower-reservoir intake structure, a new single-circuit 230-kV transmission line connecting to existing infrastructure, access routes, and associated facilities.
- Notable requirements and limits: The requested preliminary permit would provide priority to file a license application during the permit term if issued. It would not authorize construction, land-disturbing work, or entry onto another party’s property without permission.
- FERC is seeking public comments, motions to intervene, and competing applications or notices of intent to file competing applications.
