AGL is almost twice as large as the second biggest generator – who’s also in the list?

Following Wednesday’s post about the yawning gap between installed capacity and demand, which followed my article in the Australian Financial Review newspaper, it also seemed useful for our WattClarity® readers to provide the following illustration of the largest generators in the NEM (measured by current capacity ownership).

That AGL is the biggest generator is probably not a surprise for most in the industry – nor those who have read how they now produce the most emissions (notwithstanding Don’s notes about different ways that emissions can be measured), whilst at the same time (by this measure) doing more than anyone else to generate renewable energy from wind (some might see this as just two sides of the same coin of being “the biggest”).

What might be more surprising, to some, are:

1)  Where other companies rank in this listing; and

2)  How quickly the relative size diminishes as we step down the listing (note that there are a number of companies with smaller shares grouped under “OTHER”).  This might be something particularly relevant for some readers, with the mooted long-term lease of Stanwell and CS Energy (shown as “For Sale” above – here’s the current lease plan, still pending election) and the ongoing privatisation process for Delta Coastal (we’ve seen no news on that for a while?).

This information was compiled from the same data set used to prepare the 2014 Issue “Power Supply Schematic”, which is explained in the following image (though note the list above only covers the NEM, not the WEM as well):

  1. […] Hence the reduction of 480MW on AGL’s generation capacity is not going to have much impact on the company’s relative size in the market. […]
