Multi-year coal plant extensions needed to stop power price spikes - AFR

The Australian Financial Review reports that multi-year extensions of coal-fired power stations are needed to prevent electricity price spikes as the grid transitions away from coal. The article indicates that without these extensions, wholesale prices will spike during the period when coal plants retire faster than replacements come online.

Where this fits

This is a direct admission that Australia's renewables-first transition plan has a timing and reliability problem. The grid cannot meet demand through solar and wind alone during the interval between coal retirement and the completion of sufficient firming capacity. The coal extensions reveal what Energy Realism has documented repeatedly: renewables are cheap per megawatt-hour, but the whole-system cost of firming, storage and transmission to cover weather-dependent supply makes the transition far more expensive than headline numbers suggest. This is a cost and reliability pressure that exposes the absence of firm alternative capacity.

What it means

Australia is now openly planning to run coal plants longer than climate targets allow, burning more emissions over a longer tail-out period, because there is no sufficient firm alternative ready. This delays decarbonisation rather than accelerates it. The cost of this gridlock, extended coal operation plus oversized renewables plus storage and transmission overbuild, is borne by households and industry. The irony is stark: a firm, low-emission, energy-dense generation source exists and has the lowest lifecycle emissions of any power source, but remains banned by law. Australia is choosing a more expensive, slower, more emissions-heavy path because the option that could have closed the reliability gap cleanly is not on the table.
