Renewable energy sources

We're working with communities throughout regional Queensland to develop renewable sources of energy. Our goal is to reduce our impact on the environment by cutting greenhouse gas emissions, decrease our use of imported diesel and reduce harmful pollutants from diesel combustion.

Solar power station at Doomadgee

Doomadgee is an isolated community about 500km from Mt Isa. Its not connected to the national electricity grid and is reliant mainly on diesel generation for its electricity needs.

The 264kW solar photovoltaic (PV) power station works together with the diesel power system to deliver savings of around 115,000 litres of diesel each year.

The solar farm provides about 8% of the total energy needs in Doomadgee and can assist with electricity supply during extended wet seasons, which can isolate the community for up to six months.

Doomadgee's solar power station received the 2014 Clean Energy Council (CEC) Innovation Award. The project showed innovation through the development of advanced control systems. These systems seamlessly manage both the diesel engines and the solar farm to deliver a cost effective solar solution.

Wind farm on Thursday Island

Thursday Island in the Torres Strait is not connected to the national electricity grid. Its 4,000 residents rely on electricity from diesel generators.

We built a $2.5 million wind generation plant which provides around 5% to 10%1 of the island's electricity needs. This saves about 300,000 to 600,000 litres of diesel and 870 to 1,7001 tonnes of greenhouse gases each year.

The plant consists of two 30 metre steel towers, each topped with a three-bladed turbine with a rotor diameter of 29 metres. Each turbine generates up to 225 kilowatts of electricity. Their combined annual output is up to 1.22 gigawatt hours, depending on the weather.

The turbines' output is passed through a transformer and fed into the existing power station system. The turbines operate in addition to the diesel generation plant but are relatively quiet. At just 150 metres away, they’re not much noisier than the average fridge.
