The Energy Supply Association of Australia (esaa) was established in January 2004 as the peak national industry body for Australia’s energy supply sector.

esaa succeeds the former Electricity Supply Association of Australia.

esaa promotes the policy interests of the electricity supply industry and downstream natural gas sector. Its focus is on strategic, whole-of-industry policy issues affecting Australia’s energy supply sector.

esaa membership comprises the Chief Executives of more than 40 electricity and downstream natural gas businesses with $121 billion in assets, more than 50,000 employees and estimated investment needs of up to $100 billion to 2020. Together these businesses contribute more than $14.5 billion directly to Australia’s Gross Domestic Product.

esaa Chief Executives meet twice each year to determine esaa policy positions. The prioritised and strategic policy objectives that are developed focus on the long-term issues that fundamentally affect the ability of the industry to supply reliable and competitively-priced energy and provide the framework for esaa’s advocacy and communication program.

esaa is committed to working constructively to achieve the policies, regulatory arrangements and market reforms that genuinely contribute to securing Australia’s energy future. esaa actively engages with governments, policy makers and opinion shapers to ensure Australia's energy and related policy settings are informed by the expertise, analysis and views of its members. esaa also communicates the industry’s agreed policy positions and other work to key stakeholders, including governments and politicians, regulatory bodies, the media and broader community.

Complementing the work of esaa are the sector-specific energy supply sector associations, including the Energy Retailers Association of Australia, the National Generators’ Forum, the Energy Networks Association of Australia and Grid Australia, which deal with detailed, sector-specific issues.
