Australia’s largest electricity grid identifies household batteries as crucial, requiring A$122 billion ($81 billion) annually to replace ageing coal-fired power stations and address increasing energy demand.
According to the Australian Energy Market Operator’s biennial Integrated System Plan for the National Electricity Market (NEM), the final coal plant is expected to cease operations by 2038.
Additionally, after more than half a century, Australia’s coal-fired generators are reaching the end of their service life. Up to 90% of the NEM’s coal-fired power stations are projected to retire before 2035 and the entire fleet before 2040.
The plan forecasts a sixfold increase in grid-scale wind and solar generation capacity by 2050 and a quadrupling of rooftop solar installations. Additionally, the adoption of home batteries is projected to generate multibillion-dollar savings.

In the report, Daniel Westerman, Chief Executive Officer of Australian Energy Market Operator, said, “Investment is needed urgently. New generation, storage and firming must be in place before coal power stations retire to meet Australia’s growing demand for electricity.”
Recently, Australia’s major opposition parties unveiled a plan to construct nuclear plants if they regain power. Critics have voiced concerns, citing the extended construction timelines as a significant drawback.
The report reaffirmed that combining renewable energy with storage, supported by natural gas backup, remains the most cost-effective method for electricity supply. It did not include nuclear power in its modelling, as current national laws do not permit implementation.
