Kalgoorlie (Parkeston) Gas Power Plant | Kalgoorlie-Boulder, Western Australia

Kalgoorlie (Parkeston) is a gas-fired power generation facility located near Kalgoorlie-Boulder in Western Australia. With a capacity of 110 megawatts, it is a medium-scale plant serving the mining and residential needs of the Goldfields-Esperance region. The plant is owned by Newmount Australia and Transalta, and is currently operational. The facility operates on natural gas, a cleaner-burning fossil fuel compared to coal, resulting in lower emissions of sulfur dioxide and particulates. However, it still contributes to carbon dioxide emissions. The plant's technology is typical for gas-fired peaking or intermediate load plants in Australia, often using open-cycle or combined-cycle gas turbines. Australia's power generation sector is regulated at both federal and state levels, with emissions standards under the National Environment Protection Council and state-based environmental agencies. Environmentally, the plant's location in a semi-arid region with low population density reduces local air quality impacts. Its role in supporting the mining industry, a key economic driver, underscores its importance. The plant's gas supply is likely sourced from domestic fields, aligning with Australia's abundant natural gas resources. Overall, Kalgoorlie (Parkeston) contributes to grid stability and economic activity in the region.

The plant's gas fuel type results in lower CO2 emissions per MWh compared to coal, but still significant. Its location in a sparsely populated area minimizes exposure to pollutants. The semi-arid climate means water usage for cooling may be a concern, though gas plants typically use less water than coal or nuclear. Older gas plants may have higher NOx emissions. Regulatory compliance with Australian emissions standards is expected.
