Even One Nation admits Yallourn “might be too far gone” to save, which is a pretty good indication that even the most rusted-on ideologues cannot make ageing machinery last forever.
The new wind, solar and storage needed to fill that gap is being financed and built right now, based on the expectation that coal generators will retire when they have said they would. Investors need to know the business case will not have its fundamental forecasts blown apart because coal-fired power stations stay open after they are scheduled to close.
At the same time, Australia’s electricity needs are exploding. AEMO expects demand to almost double by 2050 as the population grows, and we use more electricity to power our homes, businesses, transport and industry. Renewables can meet this demand if we get the investment signals right.
So, when a company announces a closure date for a major power station, changing that date has consequences well beyond the plant itself. It can create a vicious cycle in which governments worry that replacement capacity will not arrive in time, so coal stays open longer. Investors see coal staying longer and become more cautious about financing its replacement. The shortage of new capacity then becomes the argument for keeping coal open again.
Australia needs to break that cycle. We need enough new electricity supply built early enough that extending a 40- or 50-year-old coal station is a genuine last resort, not what happens every time the timetable gets tight.
