The Queensland grid is in crisis — the forecast price for nearly the entire next 24 hours is $15,000 per megawatt hour.
I have never seen a graph like this one. It’s a “white knuckle ride” as Paul McArdle describes it. The IRPM (or Instantaneous Reserve Plant Margin) is just 8%. “This shows total Available Generation of 31,679MW ready to supply aggregate ‘Market Demand’ of of 29,201MW at this point … so a surplus of only 2,478MW NEM-wide.” But only last week there was a record day where the grid demand was 32,000MW — the highest winter demand day for years.
