Environmental Issues

• 1kWhr produced approximately
• Saves emission of 750g CO2
• Saves 0.25 litres of diesel fuel
• Reduces other emissions

• Thursday Island

11
Coober Pedy

• Located approx 800km NW of Adelaide

12
Coober Pedy

• Single turbine
• Nordex 150 generator
• Supplies 4 (330MWhrs) of towns power
• Cost 577,000
• Saves approx. 100,000 litres diesel/year

13
Ten Mile Lagoon

• Located 720km SE of Perth

14
Ten Mile Lagoon

• Nine turbines
• Vestas V27-225
• Supplies 12 (3.96GWhrs) to Esperance
• Cost 5.96 million
• Saves approx. 4 million litres diesel/year

15
Thursday Island
Thursday Island

• Located in Torres Strait off Cape York, Queensland

Queensland
16
Thursday Island

• Two turbines
• Vestas V29-225
• Supplies 10 (880MWhrs) to island
• Cost 2.5 million
• Saves approx. 360,000 litres diesel/year

17
Conclusion

• Only utilised in isolated townships relying on
  diesel generated power
• Presently not cost effective for main grids
• Future viability possible
