Hot rocks
This map shows the estimated temperature in the Kingia Sandstone reservoir zone. Blue colours are cooler temperatures and the red shades are hotter.
This geological formation occurs 3.5 to 5 km below the surface with temperatures of 150 to 200 degC.

Inferred resource
The inferred geothermal resource for the Kingia Sandstone within the STG EPA 0009 area was independently assessed by Monteverde Energy Consultants in 2022. The results are summarised in the table above.
The mid case estimated power output is 226 MW for a period of 30 years. The above values were calculated by reference to the total area of the GEP application (STG EPA 0009) minus the rock volumes associated with gas accumulations known at the time.

For comparison, the Collie Power station, which has a name-plate capacity of 340 MW, is one of several West Australian coal-fired power stations in the Collie area scheduled to be retired by 2030. This geothermal resource in the State’s Mid West could potentially replace over half the output from that plant with clean, zero emissions, dispatchable power.
