Australis's Wind Energy Generation Capacity

Published data reveals Australia has made great strides in increasing Wind Electricity Generation Capacity. This capacity has a significant place in Australia's future energy generation mix.

Potentially challenges I see, in modelling each potential energy capacity, are these;

MW vs MWh - Reliability

MW is the most common used statistic, which makes sense from an engineering perspective. If not enough MW are provided to the system, the system shuts down. The challenge of MW statistics, when it comes to capacity planning, is it does not allow for available capacity. For example, if the wind is not blowing, available capacity is zero MW.

In CSIRO's latest GenCost report, average available capacity for Wind was estimated to be 30%. AEMO's own reporting suggest reliability contribution of 22% for Wind.

Decomissioning

Decommissioning rates for Wind plant are far greater than for many alternative energy sources. This adds to whole of life costs for Wind capacity; costs include initial construction, maintenance, decommissioning and re-installation. These do not appear to be explicitly accounted for in cost models?

Capacity Planning

Modelling from 2015 to 2050 demonstrates considerable progress in Wind generation capacity; but forward modelling is not published, or opaque? Facts-based discussion would help the community; explicit publication of planned sites, by individual site (unaggregated) would assist in public discussion.
