COMMUNICATIONS The Power Station has a phone line but not internet connection available. WATER SUPPLY The Power Station is supplied with water by SA Water.

1.1.2. MARREE POWER STATION - TECHNICAL OVERVIEW GOVERNING Load sharing, VAr sharing and Synchronising are controlled by a ComAp digital controller for each Gen. Set. The ComAp controllers communicate on a private communications network. REMOTE ACCESS Remote access to the control system is possible with suitable VPN and remote control software installed on the remote PC. When required one of the ComAp stations would be remote controlled. Access is restricted to users with correct credentials. FUEL SYSTEM There is a single 58,000 litre diesel fuel tank at Marree.

Power Station – Diesel Fuel Tank

The diesel fuel tank pumps to the generator day tanks automatically controlled by level sensors in the day tanks, dependant on the priority order entered on the HMI system. The fuel level is monitored by a digital level sensor with feedout available to the local operator and as a data tag in the ComAp monitoring system.

LPG storage vessel owned and maintained by ELGAS. 7500 litres, manufactured 1987. On 11/9/2013, as inspected by ELGAS appointed inspector, the tank valves pipes and gauges were in good condition. FEEDERS The Marree Power Station utilises a 415V/11kV step-up transformer which supplies the power to the community.

The town was once a terminus town for the Central Australian Railway. In 1981 a new standard gauge line was built which bypassed Oodnadatta, the town now caters mainly for tourists. The 2006 census reported a population of 277 (150 male, 127 female, including 103 indigenous Australians). The Oodnadatta Progress Association and the Outback Communities Authority (OCA) officially represent the interests of the community. The OCA also recognises the Dunjiba Community Council representing indigenous people in the area. Oodnadatta experiences summer maximum temperatures of 48.0 degrees Celsius with an overnight low of 16.1 degrees Celsius throughout January. Whereas in winter temperatures range from a maximum of 25.3 degrees Celsius to a low of 2.8 degrees Celsius in June. There is an average annual rainfall of 95.8 millimetres.

GENERATION Parachilna power, unlike other RAES sites, is generated via a solar/diesel hybrid power system. It includes a: • 120 mono-crystalline panels each producing up to 175 W of electricity • 50 kVA bi-directional inverter which interfaces with the diesel generator

controls and the battery array.

24

The system operates automatically to displace diesel generation with solar generation when available. The inverter control system can be remotely monitored from Adelaide and provides detailed information on the generation and distribution of electricity in Parachilna.
