Big Battery prices on fire in Australia last quarter
The Renewable Crash Test Dummy suffers yet another nasty price surprise. We have more batteries than last year but the average price per megawatt hour has doubled.
In June there were a few hellfire price spikes where the prices on the National Energy Market launched up to an obscene $10,000 a megawatt-hour and then levitated there for hour after hour. These spikes had a width like we rarely see. Now, with the latest AEMO Quarterly Report we know that the spikes were due to the batteries.
On the left, the price spike of June 26th. On the right, the timing of the battery discharging…
And just so everyone can see how much energy the batteries provided — note the patch marked “Battery” below in the daily load curve of June 26th. The black line across the top is “total demand”. Most of the area under that curve was provided by the evil, but reliable, fossil fuels. Batteries contributed just 0.7% of total NEM generation.
