So I’m still going ahead and listing the trips that have occurred this summer to coal fired generators. The amount of trips may or may not be more or less than in any other year, but it does dispel the myth that this type of generation is ultra-reliable. No trip is predictable! Hopefully this might educate the reader that the hyperbole emanating from certain sections of the government and the media suggesting that coal fired base load is the ONLY answer should be looked upon with derision.
My claim that there had been 41 trips this summer has proven to be inaccurate, and must have been based on information not exactly up to date. The number is actually 48 up until last night. Please note that I have not included Gladstone because I could not accurately differentiate between apparent trips and deliberate taking off of units due to demand, a not uncommon event at power stations with comparatively small capacity units (Hazelwood was similar).
Data is sourced from AREMI by expanding the trend to 3m for each coal fired unit in Vic, NSW and Qld and counting the excursions to 0MW.

Did anyone notice that there were four trips, some overlapping, during the heatwave across the 13th and 14th of December? How does that make coal ‘reliable’?
