Kwinana Power Station (KPS) was Synergy's second-largest power station, located in Naval Base, Western Australia within the City of Kwinana.

At its peak, power was produced from six turbines driven by steam from boilers fired by coal, natural gas or fuel oil, and one gas turbine.

[clarification needed][2] This is not to be confused with Cockburn Power Station to its immediate south.

[3] A 20 MW gas turbine, able to be operated on natural gas or diesel fuel, was added in 1972 and took the total nameplate rating to 900 MW which was the station's peak.

In 2005 oil burning was re-introduced making the power station unique in Western Australia as it could burn the three fuels: coal, natural gas and oil.
