South Australia, with 40% renewables, is lucky this has been a mild summer.*
Welcome to your load-shedding future:
Widespread power blackouts were imposed across Adelaide and parts of South Australia with heatwave conditions forcing authorities to impose load shedding.
About 40,000 properties were without electricity supplies for about 30 minutes because of what SA Power Networks said was a direction by the Australian Energy Market Regulator. — The Australian
Premier Jay Weatherill blamed the AEMO for not ordering a gas power station to come online.
Electricity prices spiked to $13,440 MWh. Total demand was about 3,000MW. Things are expected to be the same tomorrow.
At 6pm tonight wind power was producing less than 100MW (about 7% of its rated capacity):
Look at the price spike and the forecast for tomorrow:
Perhaps with better planning and more money they can reduce the need for planned blackouts — but why bother?I guess they’ll have those gas powered stations running tomorrow.
*The Wind power graph was supplied in WA time, so I pushed the clock by 2.5 hours on the scale to make it “SA Time”.
BACKGROUND to the SA Electricity crisis (all the links).
People saw The South Australian black out coming. There were warnings that the dominance of renewables made it vulnerable. Then when it came, it all fell over in a few seconds — read the gruesome details of how fast a grid collapses: Three towers, six windfarms and 12 seconds to disaster. Ultimately the 40% renewable SA grid is crippled by complexity. The AEMO Report blames renewables: The SA Blackout was due to lack of “synchronous inertia”. The early estimates suggest the blackout costs South Australia at least $367m, plus their normal electricity is twice the price, and there are reserve shortfalls coming in January 2018 (pray for a cool summer). Welcome to the future of unreliable electricity: Rolling blackouts ordered in SA in 40C heat. And more bad luck for South Australia, yet another blackout, 300 powerlines down, 125,000 homes cut off.
