Dubbo Firming Nominees Pty Ltd is a wholly owned subsidiary of Squadron Energy which is part of the Tattarang group of companies.
Dubbo Firming Nominees was formerly part of CWP Renewables (CWPR), and CWPR was acquired by Squadron Energy in late 2022. All CWPR development and operational projects, including the proposed dual-fuel Dubbo Firming Power Station, have continued as normal under the Squadron Energy brand.
Squadron Energy has over 2 GW of renewable power projects in construction and operations and has about 20 GW of renewable, storage, and firming projects in the development pipeline.
Firming power capacity needed
The proposed Dubbo Firming Power Station project will operate as a “firming” generation facility supplying electricity at short notice.
With a capacity of up to 64 MW, it will firm up the power supply when the sun is not shining, and the wind is not blowing to guarantee that the electricity supply can be maintained irrespective of weather.
Utilizing open cycle gas turbine (OCGT) technology, the dual-fuel power station will be capable of operating on biofuel and fossil gas with hydrogen blends in the short to medium term with a view to transitioning to 100 percent hydrogen and biofuel systems.
With an up to 20 MW electrolyzer, the proposed project will produce hydrogen when there is excess electricity in the grid.
Generation from this project will be used to firm renewable energy generation. While our pipeline of wind, solar, and storage projects will enable us to provide 90- 95 percent renewable electricity, our firming projects like the Dubbo Firming Power Station will supply the remaining 5-10 percent, explained Jeff Allen, Senior Project Developer for Dubbo Firming Power Station.
The estimated AU$190 million investment is expected to support up to 150 construction jobs and five operational jobs.
If approved, it is expected to be operational in the second half of 2025, and anticipated to operate at a capacity factor of about 12 percent in any given year.
