AEMO Services launches next competitive tender for long duration storage

9 May 2025

Today, AEMO Services Limited acting as the NSW Consumer Trustee launched its sixth tender under the NSW Electricity Infrastructure Roadmap (the Roadmap), seeking an indicative 1 gigawatt (GW) of long duration storage projects in NSW.

The tender is open to projects connecting to new planned infrastructure in Renewable Energy Zones with Access Schemes, or existing infrastructure state-wide.

To be eligible for this tender, projects must have the ability to dispatch at their registered capacity for a minimum of eight hours. AEMO Services is seeking projects that can be operational by 2034 to support the achievement of NSW’s minimum objectives of 2 GW and 16 GWh by 2030, and at least 28 GWh by 2034.

AEMO Services’ Executive General Manager Nevenka Codevelle said the success of the recent Tender 5 for long duration storage projects, which were announced in February, would serve as a running start for the next round.

“Tender 5 was the most successful long duration storage tender to date. It demonstrates the strong market interest to invest in long duration storage projects and we’re excited to see more in Tender 6.”

“AEMO Services uses a two-stage tender process that assesses a project’s social licence commitments, deliverability, impact on the grid and quality of proponent. The second assesses a project’s financial value to NSW electricity consumers.

“We want to see more short lead time projects that contribute to our 2030 minimum objective. With the recent addition of a new minimum objective of at least 28 GWh by 2034, we are now able to support projects with a longer lead time that will come online in the next decade,” Ms Codevelle concluded.

In its role as Consumer Trustee under the Roadmap, AEMO Services has already supported projects expected to contribute more than 2.4 GW of generation, 18 GWh of long duration storage and almost 3 GWh of firming capacity to NSW’s energy grid.

Project bids will close on 10 June 2025.
