The company appointed Pacific Energy subsidiary Contract Power Australia as preferred contractor to build, own and operate the project's proposed power generation facilities.
Coburn's purpose-designed power infrastructure is based on low-cost, low-emission solution integrating natural gas fuelled generation with state-of-the-art solar and battery storage technology.
The proposed power solution enables Strandline to capture energy supply cost savings relative to the June 2020 definitive feasibility study.
The power station is designed suitable for a maximum demand capacity of 16 megawatts and average consumed power of about 10MW.
A joint venture between Woodside Energy (and EDL LNG Fuel to Power has been appointed as preferred contractor to supply LNG to the power station via road train from Woodside's Pluto LNG facility near Karratha.
The proposed LNG supply contract is over a 10-year term (with appropriate pricing review and adjustment mechanisms) and also enables Strandline to capture energy supply cost savings relative to the DFS.
"The company continues to move rapidly towards development of Coburn and these key contract appointments to well-credentialed suppliers provide delivery certainty," Strandline managing director Luke Graham said.
Strandline will now work on finalising documentation with the suppliers.
