Yarnima Power Station

Key Facts

• Number of staff at peak: 115
• Volume of concrete: 6,200m³
• Tonnes of REO: 900

Project Overview

• Yarnima Power Station will involve installation of a gas turbine generator that will operate in open cycle for the first year. The power station will then be expanded to a combined cycle configuration. This will involve the installation of additional gas turbine generators, heat recovery steam generators, steam turbine generators, substation equipment and associated balance of plant.
• The plant will be installed adjacent to the existing Newman power station located in the Pilbara Region of Western Australia. The Site is accessible by air, road and rail. Newman is located approximately 416km south east Port Hedland and is accessible by road from Perth and Port Hedland. The nearest domestic airports are at Newman and Port Hedland.
