A hypothetical case of what production patterns from wind might look like through a year with increased installed capacity of wind farms.
A more detailed look at how the percentage of energy supplied in the NEM from wind has risen to be 3.5% on an annual basis – though the degree of indeterminacy continues to be significant despite the growing diversification of wind farm sites.
Rather than just drawing a lucky winner out of a hat, or using a random number generator, someone suggested we take a different approach – and here are the results.
