Ember's analysis found that about 2.1 TWh of renewable electricity generation was curtailed in fiscal year 2025–26, equivalent to 1.3% of total renewable generation, to keep coal-fired power plants operating at their minimum technical load. The report estimates that around 10 GWh of energy storage, charged during peak midday solar generation hours, would have been sufficient to absorb this surplus renewable output, maintain coal plants above their minimum technical load, and avoid the curtailment altogether.
