New Australian wind farms reach nearly 50% capacity factor

Two new Australian wind farms are nearing capacity factors of 50 per cent – and are the best performing wind farms in Australia, according to their owner, Windlab.

Windlab tweeted the above graph on Tuesday, showing that the 20MW Coonooer Bridge wind farm in Victoria, and the newly-opened 31MW Kiata wind farm, also in Victoria, were delivering capacity factor ratings in excess of 45 per cent.

Respondents on social media were quick to point out that this was nearly as good as the Liddell coal fired power station, which delivered a capacity factor of 49 per cent in 2016/17, and which had two units closed for most of the period highlighted above.

Windlab CEO Roger Price told RenewEconomy that the results were pretty much as expected, and reflected both the company’s own wind resource technology, and the development of wind turbines, which are getting bigger and more able to generate power at lower wind speeds

Coonooer Bridge installed Vestas turbines with 117m diameters, Kiata included Vestas turbines at 126m diameters, while the Kennedy energy hub – featuring wind, solar and battery storage – will also aim for high 40 per cent rating with 3.6MW turbines and 135m diameter blades.

“This is up where we expected it to be,” Price told RenewEconomy. They are doing very well. These are smaller projects, but they are amongst the best wind resources in Australia.”

    if Cooper’s gap can deliver this it would be massive!

      Silverton (200MW) should be around 44.5% also.

    Hi All, As we progress in time the engineers are making progress to lots of improvements. Wind Farms often have a design life of 25 years (the average car only lasts about 15 years at the most). The capacity factor will slowly creep upwards, and when they are built in effective zones we will see improvements dispite what the nay sayers say. The Dutch have been replacing their small Kw units with bigger MW units and some web siites are claiming that it’s blade failures that are causing the change over, not that they are old and near the end of there useful life. The change has resulted in less WTG’s overall but an increase in RE from wind. When wind first started they were in the high teens – low twentys capacity factors (CF). There will be farms that are close to 50% CF and Tas may be one area that acheives that.

    This is excellent news. It shows how much learning and development this industry continues to have.

    would love to see the daily/seasonal output-time distribution of these windfarms, see how much they are complementing solar output.

      I would like to see that too. Solar and Wind generation go together like sex, drugs and rock’n roll. Less storage needed also.
