Is AGL Energy actually the NEM’s greenest generator?
A different look at the numbers suggests that AGL Energy does have some green credentials…

Privatising profits whilst socialising costs – part 1 (wholesale)
Some initial thoughts about some of the areas (in the wholesale market) where there’s been finger-pointing in different directions about “socialising costs whilst privatising profits”
What happens if (when?) existing wind farms cross to “the Dark Side”?
A quick look at a price spike that occurred Monday evening (4th August) in South Australia
Spot prices back to yesteryear
Spot prices in the doldrums with low demand and high production from wind and gas.
Wind output drops and volatility rises
After spending a day looking into the future (at prospective generation developments) I noted this reverse correlation between wind and volatility that’s been occurring over the week.
First day without the Carbon Tax here, … maybe?
An interesting half-hour this morning in the NEM
Windy week blows in change in Canberra
With the repeal of the carbon tax looking more likely, and July 1st only just around the corner, someone asked today if we could calculate what the spot price might be without carbon.

NEM-wide demand steams towards 32,000MW, and prices explode, as heatwave hits Victoria and South Australia
The forecast heatwave arrives in Victoria and drives demand towards what looks like being the highest (so far) this summer, and causing prices to pop.
High temperatures drive NEM-wide demand towards 30,000MW
Demand surges in Victoria and South Australia on the back of blistering heat, dragging prices out of their long-term slumber as a result.
The NEM might support 37% energy supplied from wind – but it would still require at least 21GW of non-wind capacity on standby
A hypothetical case of what production patterns from wind might look like through a year with increased installed capacity of wind farms.
Aggregate wind farm output growing, but intermittency still remains
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.
Performance of wind farms, to date in 2013
Here’s a view of how daily wind farm production (by region, and NEM-wide) has trended over the 2013 calendar year to date – the correlation of output on a daily basis, and the contribution towards regional and NEM-wide demand
Daily wind generation does not seem to be close to 90% of South Australia’s supplies–are we missing something?
Wind generation on some days in the past 2 weeks supplied a big percentage of SA demand – but not (on a daily basis, at least) near the 90% level.
