Neerabup Gas Fired Power Station

Katestone Environmental was commissioned by ERM Power Pty Ltd to prepare an air quality assessment and a greenhouse gas assessment of a proposed gas-fired power station at Neerabup in Western Australia. The proposed NewGen Gas-Fired Power Station consisted of two open-cycle gas-turbines each with a nominal capacity of 165 MW and a total power station nominal capacity of 330 MW.

The air quality assessment for the NewGen Power Station is typical of the type of assessments undertaken on a day-to-day basis by Katestone Environmental.

These assessments include the following components:

• Discuss and agree on specifics of methodology with regulatory agency.
• Characterisation of the existing air quality and meteorological conditions in the region.
• Estimation of levels of air pollutants likely to be emitted from the power station.
• Consideration of meteorological conditions and local terrain features that could affect the transport and dispersion of air pollutants.
• Prediction of ambient air pollutant concentrations in the vicinity of the power station due to existing major industries and proposed power station (TAPM and CALPUFF models are generally used for complex studies).
• Estimation of regional impacts on ozone due to the proposed facility.
• Assessment of the predicted impacts against air quality goals and standards.
• Estimation of the predicted contribution to Australia’s greenhouse gases.
