Yarnima Power Station Stage 4 (Gas Reciprocating Engines)

Overview

The proponent, BHP Iron Ore Pty, proposes to increase power generation capacity at the existing Yarnima Power Station, approximately 2 kilometres north-west of Newman in the Pilbara. The proposal comprises an increase in installed firm power generation capacity from 154 megawatts up to 239 megawatts via installation of gas reciprocating engines and associated infrastructure. The gas reciprocating engines are proposed to be installed in stages up to a maximum of 120 megawatts (nominal). 

Associated infrastructure included in the proposal includes switch rooms, electrical connections, a new gas heater, extension of fuel piping, water supply systems and other auxiliary equipment. 

Clearing of native vegetation is not proposed.

The Yarnima Power Station occurs within the Nyiyaparli Native Title Determination Area.

Peak annual greenhouse gas emissions are predicted to be: 

• Scope 1 (power generation): 480,030 tonnes of CO₂ equivalent per year (tCO₂-e/yr) 
• Scope 2: NA 
• Scope 3 (fuel supply): 37,260 tCO₂-e/yr. 

Why your views matter

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
