ARTC 20kW Solar Power System Case Study

Case Study CS0015 - ARTC 20kW Solar Power System Commercial Off-Grid

Background

In June 2011, MPower, project managed and installed a 20kW solar power system on a remote off grid site for the Australian Rail Track Corporation (ARTC). The entire railway site camp, located 200km east of Kalgoorlie on the Trans Australia Rail Line at Zanthus rail sliding, is running on solar power.

Prior to the installation of the new system, the site was powered 24/7 by a 50kVA diesel generator, consuming 200 litres of diesel per day. Solar power is now expected to contribute up to 80% of the site’s energy needs with the diesel generator remaining as a back-up power source in times of peak demand or for battery charge on days of poor sunlight.

The site installation took 4 weeks with 25 tonnes of equipment installed and 15m³ of concrete for solar array footings. With a project value of $450,000 (50% contribution from Renewable Remote Power Generation Program rebate), the estimated payback time is 3-4 years.
