Some quick notes Tuesday evening about liquid-fuelled peaking generators getting a run in a South Australian region that’s missing Northern station (amongst other factors)
With Queensland temperatures (even at the Brisbane airport) exceeding 40 degrees Celcius today, the electricity demand was also high – though still below the all-time record.
2 Commentson "South Australia hit by two price spikes"
Demand spiked, Angaston (diesel) dropped 37 MW, and Ladbroke (gas, price setter) was constrained down due to network limitations. Wind dropped 5 MW the first event and 18 MW the second time. Small changes compared to diesel and demand.
