2 x Westinghouse 501B 73 MW Dual Fuel Gas Turbines

2 x Westinghouse 501B 73 MW Dual Fuel Gas Turbines
Location:California
Description
Two (2) Westinghouse 501B dual-fuel gas turbine generator packages available from a former combined-cycle power station.
This is a rare opportunity to acquire utility-scale Westinghouse 501B gas turbine assets from a legacy 60 Hz power plant application. These are large-frame industrial units originally installed in combined-cycle service and supported by major electrical balance-of-plant infrastructure. For buyers seeking real megawatt-scale equipment without new-unit lead times, this is the kind of package that deserves serious review.
Available documentation and site records identify these units as Westinghouse 501B combustion turbines, originally configured for dual-fuel operation on natural gas or distillate/liquid fuel, with a nominal 73 MW net output per unit. One turbine nameplate photo on hand confirms Westinghouse Gas Turbine model W-501-B and 3600 RPM. Permit records for the plant also identify the 501B units as 16-burner dual-fuel combustion turbines originally tied into HRSG service as part of the station’s combined-cycle layout.
These units are well suited for buyers pursuing:
- utility and industrial power generation projects
- peaking and standby generation development
- repowering opportunities
- refurbishment and relocation programs
- large private power applications
- data center and other high-demand power strategies where speed to market matters
The strongest value in this offering is the gas turbine/generator package itself, along with the remaining major electrical balance-of-plant associated with the plant. Site photos and records show substantial supporting electrical infrastructure still present, including breaker gear, bus/switchyard-related equipment, control enclosures, and plant documentation/manuals, subject to final confirmed sale scope.
