Paulsens Gold Mine

The challenge

Paulsens is an underground gold mine located 180 kilometres west of Paraburdoo, Western Australia. Production began in 2005. Powerwest was engaged to provide reliable, continuous power to this very remote site and, since 2005, has continued to supply power under a build own operate (BOO) model.

The solution

In 2005, we assessed the site’s requirements and installed six Cummins power generators with a capacity of 4.8MW. In 2010, Northern Star purchased the mine, and based on our capabilities and track record of reliable power supply, Powerwest was retained as the sole power provider. In February 2014, a second power station with five new Cummins engines and a capacity of 4MW was installed to support the site’s continued expansion. In 2016, further site expansion led to the installation of three new Cummins engines, adding 2.4MW of power.
