The peak load for South Australia was 1.8 gigawatts. No, that's the average load at a particular time of day. (Averaged over all days over two years). The peak is about twice that: South Australia experienced a mild summer with only a few days exceeding 40°C. A relatively short heat wave
occurred in late January 2011. The maximum demand for the year was 3,433 MW, and occurred 4:30 PM (Australian Eastern Standard Time)
Monday 31 January 2011 (at a temperature of 42.9°C). A higher maximum might have been expected if the same
conditions had occurred later in the week, after an extended hot weather period. http://www.aemo.com.au/~/media/Files/Other/planning/0400-003... |

That said, it actually makes my case significantly stronger. With 10% EVs and 20kW chargers, you can put 2.5 GW into the grid at peak, which is over 2/3 of the instantaneous maximum demand for the year.
I'd love to see figures on how much you could save providing a grid with 1.8 GW of base load vs having to engineer it to be able to handle nearly twice that, once a year.
You'd have to go to 15-20% EVs to support that, but if you're shutting down half your traditional power stations and investing heavily in solar, it may actually make sense with today's prices. Then again, lithium prices would skyrocket going to those kinds of extremes...
