Solar Systems has constructed three concentrator dish power stations in the Northern Territory which together generate 720 kW and 1 555 000 kWh per year. This represents a saving of 420 000 litres of diesel fuel and 1550 tonnes of greenhouse gas emissions. In 2003 Solar Systems completed construction of the first concentrator dish power station at Umuwa in South Australia. Solar Systems is a winner in the 2005 Engineering Excellence Awards.
