Tasmania leads the nation in renewable electricity as pumped hydro ambitions grow

Tasmania occupies a unique position in Australia's electricity system as a jurisdiction that already generates effectively all of its electricity from renewable sources — primarily the extensive hydroelectric system that was developed across the island's central highlands through the twentieth century, supplemented by a growing fleet of wind farms. This renewable energy baseline gives Tasmania a competitive advantage in an energy market that is progressively pricing in the carbon intensity of electricity generation.

The Marinus Link project, which would establish a second electricity interconnector between Tasmania and the Victorian mainland, is central to Tasmania's strategy of becoming a clean energy exporter. The additional interconnector capacity would allow Tasmania to export its renewable electricity surplus to the mainland during periods of high generation and low local demand, generating revenue for the state while contributing to Australia's broader decarbonisation objectives.

Pumped hydro development is another dimension of Tasmania's clean energy ambitions, with proposals to use the state's existing hydro reservoirs as the upper storage in pumped hydro systems that could store surplus renewable energy from the national grid and release it during peak demand periods. This role as the "battery of the nation" has been articulated as a long-term economic development strategy that leverages Tasmania's natural geography in the national energy transition.

Green hydrogen is a further opportunity that Tasmania's renewable energy advantage creates, with proposals for hydrogen production using Tasmania's surplus renewable electricity that would be exported to Asian markets as a clean fuel. The feasibility of this pathway depends on global hydrogen market development and the economics of production and liquefaction, but Tasmania's renewable energy starting point gives it a genuine competitive position in the global green hydrogen supply chain.
