We have announced the results of Tender Round 3 - generation and long-duration storage infrastructure in NSW.
Five projects representing 750 MW of renewable energy generation and 524 MW (4,192 MWh) of long-duration storage have received Long-Term Energy Service Agreements following AEMO Services’ rigorous two-stage tender assessment process. Each of the storage projects will have a continuous discharge capacity of at least 8 hours.
For more information on successful projects, view the Market Briefing Note.

The tender sought an indicative 2,500 GWh (around 950 MW) of generation and up to 550 MW of long-duration storage capacity.
Benefits of LTESA Awarded Projects
Collectively, the awarded LTESA projects will provide:
- Consumer value: Financial bids in the tender were very competitive and were well below the estimated levelised cost of energy. Some bidders also cut options from the contract or have the LTESA in place for only a part of the project, reducing the size of the subsidy they could receive and providing better value for NSW consumers.
- Energy delivery: Successful generation projects are expected to produce enough clean energy to power over 360,000 households per year. Successful LDS projects are capable of providing enough electricity to power 725 households from a single full cycle.
- Investment: More than $4.2 billion in total investment in NSW’s renewable energy infrastructure.
- Jobs: The projects will support more than 1,000 jobs over their lifetimes.
- Community and regional economic development.
