A bit counter-intuitive perhaps, especially given the AGL-bashing that’s been going around of late.
Following yesterday’s post about the AGL portfolio (expanded now to include Macquarie Generation), we wondered about the company’s share of wind farm production in the NEM. Hence we ran some additional queries today in NEM-Review (this time sorting by “Trader”) and present this today. Interested in what you think (either offline or online)?
Portfolio share of wind production in the NEM
The following chart shows the trended production of wind from portfolios in the NEM.
This clearly shows AGL is more than twice as large as any other portfolio for wind power produced.
To protect the identity of those lagging AGL (i.e. everyone else) we have anonymised the other portfolios:
(a) Anyone with their own copy of NEM-Review can run the same analysis –
(b) For those without, if you want to email us (firstname.lastname@example.org ) we can send you an Excel file with the relevant other portfolios identified.
Here’s the data shown another way:
I think I can understand why there have been criticisms from some quarters as AGL has diversified its asset based in recent years – firstly with Loy Yang A and now recently with Macquarie Generation.
However the fact that AGL Energy contributes more than 30% of the wind energy supplied to the NEM (and that this share has been growing as that segment of the market has grown) presents some balancing data. These existing AGL assets will also be exposed to whatever might happen as a result of the current RET Review process.
Wind share of scheduled demand in the NEM
In order that we provide some grounding to the above, we reiterate that wind is still a small (but growing) share of the overall energy mix supplied in the NEM.
The following is not exactly an apples-to-apples comparison (as the NEM-Wide demand shown is Scheduled Demand – whereas some wind farms are Non-Scheduled so act to net off this demand), but does show this trend:
