It is a bit like the situation in W.A.
And don't forget the other 2 x 120MW that could fire two fuels.
At the risk of making another "electrical" post in an unrelated thread, the situation with energy generally in WA is actually a very good example of all that ails Australia at the moment.
In short, what they've done is:
1. Have the private sector build a massive amount of new generating capacity that isn't actually needed and in some cases is prohibitively expensive to run (far more so than the existing plants being closed).
2. Become overly reliant on one particular fuel (gas) via a single pipeline which didn't work out too well when a gas processing plant blew up a few years ago. The response to that was to re-commission 4 x 50 year old units at Muja power station which had been shut down. That cost an outright fortune and 2 of those units still aren't generating power and likely never will.
3. To address the over-supply, they've shut down Kwinana Power Station, the second largest plant in WA and the most flexible in fuel supply (coal, oil, gas can be used interchangeably in 4 of the 6 units, the other two being oil or gas). Whilst closing KPS has saved some money as such, it would be far cheaper to have not built all those new plants in the first place.
4. Now the cost of mining coal is going up, first sending the mining companies broke and in due course once the price is passed on, making the coal-fired plants less economic to operate.
5. Mining costs are rising because the best and most easily accessed coal has already been used and what remains is more costly and inferior. In short, that's resource depletion staring you right in the face. And the proposed solution? Ramp up production and export the coal, thus accelerating depletion.
6. And then there's gas. WA has heaps of it but it's actually somewhat scarce locally given that the vast majority is now committed to export. Scarce to the point that there's a government report that suggests importing coal from Indonesia as one possible workaround. Yep, that's right, export the coal we have and then import more.
It's a sad tale the whole thing and it's costing the state over $50 million a month in losses to my understanding, a figure that is increasing and won't be going away anytime soon. Meanwhile WA keeps muttering something about wanting their share of GST to fill the self-inflicted black hole.
My point here is not really about keeping the lights on in Perth. It's about the incredibly stupid way we're running things in this country. A lack of foresight that has to be seen to be believed, failing to see what's obvious and staring our supposed leaders in the face. Unfortunately this situation is not confined to WA and it is not confined to the energy industry. Rather, it's a broad problem facing practically everything we're doing at the moment, the WA power industry being just one example (albeit one with fairly broad consequences economically).
