The world-first solar diesel power stations built by Horizon Power in the east Pilbara generate more than 1000 MWh (or 1 GWh) of renewable electricity per year, which is 30 per cent of the towns annual energy demand. CPS National was contracted by Sunpower and was accountable for the electrical, mechanical and civil contracting of the PV system.

The towns have been receiving reliable supply of power since the commissioning of Marble Bar in May 2010 and Nullagine in October 2010. The state-of-the-art power stations incorporate single axis tracking solar farms with diesel technology and short-term energy storage systems. This combination of technology was the first of its kind in the world and ensures a very high level of solar energy penetration into the towns’ networks and a reliable supply of power.

The power station generates 1,048 MWh of solar energy per year and provides 65 per cent of day time energy demand from solar power which in turn saves between 35-40 per cent diesel consumption per year (405,000 litres of fuel per year) whilst off setting 1100 tonnes of greenhouse gas emissions per year.
