Six new battery energy projects secured in state’s largest ever tender for long duration storage

05 February 2026

NSW has taken another significant step towards meeting its ambitious targets for new energy storage infrastructure, with ASL announcing that six new long-duration storage (LDS) battery projects have been contracted as a result of its latest tender for the NSW Roadmap.

NSW has now contracted enough capacity to meet the Roadmap’s legislated Minimum Objective of delivering 2 GW of LDS by 2030 and 28 GWh by 2034.

The projects represent an additional ~1.17 GW / 12 GWh of LDS capacity, taking the total of new storage capacity under contract in NSW to 30 GWh – marking strong progress towards the 42 GWh required by 2034 under ASL’s stretch infrastructure objectives set through our 20-year development pathway.

This is the largest tender for storage capacity awarded in NSW to date, both in terms of total gigawatt capacity and number of contracted projects. It follows the record ~1 GW / 13.8 GWh of storage secured by ASL in its last LDS tender, announced in February 2025.

Once operational, the additional storage will increase the reliability and energy security of the NSW electricity system. Several projects will also be capable of providing essential system services, including frequency and voltage control.

All projects are expected to reach commercial operations before 2030.

As NSW’s independent Consumer Trustee, ASL set an ambitious development pathway in the 2025 Infrastructure Investment Objectives Report, aiming to secure 42 GWh of LDS by 2034 - significantly above the statutory minimum objectives. The higher target was selected due to the potential benefits of additional storage to consumers, including resilience to reliability risks.

To meet the more ambitious development pathway, ASL is using Roadmap tenders to seek out both short- and long-lead time projects that can be accelerated to financial close and commercial operations through Long -Term Energy Service Agreements.

The LDS LTESA is designed to solve the ‘missing money’ challenge for long-duration storage projects, improving bankability and accelerating delivery of new electricity infrastructure.

Limondale BESS, the first project awarded an LDS LTESA (in 2023), is now in commissioning and nearing commercial operations.

The next LDS tender will commence in Q2 2026, seeking 12 GWh of projects, followed by a further 12GWh in 2027. These tenders will seek more projects that can be operational by 2030 to further support the 2030 Minimum Objective, in addition to longer lead time projects that can be operational by 2034. Concurrently, ASL will recommence tenders for the Generation LTESA, with a tender seeking 2.5 GW of projects also scheduled to commence in Q2 2026.

A tender seeking 500 MW of firming and demand response projects that can be operational by the end of 2027 is currently underway. This tender remains on track to be completed by the end of May 2026.

Quotes attributable to ASL CEO Nevenka Codevelle

“The tender process and the financial products we’ve designed are working as intended, and NSW is on its way to meet the high bar we’ve set for securing long-duration energy storage.

“An important objective of the Roadmap was to bring-forward investment in long-duration storage, and that’s what we’re seeing.

“It’s encouraging to see that proponents are continuing to utilise and value the flexibility of the LTESA product to suit their project’s needs. These agreements also deliver value to consumers by unlocking investment into additional capacity that can reduce price volatility.

“We’re about to see the first LDS projects contracted through these tenders come online. These are eight-hour-plus storage projects that would not otherwise have reached financial close or delivered energy for NSW consumers. It’s a very exciting time for the NSW energy transition.

“We update our development pathway and tender plan at least every two years, and as it currently stands we have two further long duration storage tenders scheduled – in the second quarter of 2026 and another in 2027. There are no guarantees of further LDS tenders beyond this point, so we expect competition to strengthen even further for these future tender rounds.”
