Port Stanvac Diesel Power Plant | South Australia Peaking Facility

Port Stanvac is a diesel-fired power plant located in South Australia, near Adelaide. With a capacity of 57.6 MW, it operates as a peaking plant, supporting grid stability during periods of high demand. The facility is owned and operated by Infratil Energy Australia Pty Ltd. The plant uses oil as its primary fuel, typical for diesel peaking plants that can start quickly to meet sudden demand spikes. In Australia, such plants are subject to national emission standards under the National Environment Protection Council (NEPC) and state-level regulations. The technology is based on reciprocating engines, which offer flexibility but have higher carbon intensity compared to combined-cycle gas turbines. Port Stanvac plays a role in ensuring energy security in South Australia, a region with high renewable penetration. Its ability to ramp up rapidly complements intermittent sources like wind and solar. The plant's location near Adelaide allows it to serve the metropolitan area's peak loads effectively.

The plant's diesel fuel source results in higher CO2 emissions per MWh compared to natural gas or renewable sources. Its proximity to Adelaide's population centers means local air quality impacts from NOx and particulate emissions are a consideration. The facility operates under Australian emission guidelines, which require monitoring and reporting of pollutants. Its age and technology (likely older reciprocating engines) may result in lower efficiency and higher emissions per unit of output compared to modern gas turbines.
