Our plan to meet NSW energy consumers needs

2023 IIO Report

The 2023 IIO Report shows a continuation of large investment opportunities in NSW to achieve the State’s infrastructure investment objectives to 2030 and beyond.

IIO Report updates

Updates since the Draft 2023 IIO Report

• Generation infrastructure: the final Development Pathway for generation is similar to the draft. The modelled construction of generation infrastructure shows a linear trajectory from now to 2030, and the 10-Year Plan continues to show the investment opportunity with consistent tenders for long-term energy service agreements for generation.
• Long-duration storage infrastructure: the final Development Pathway for long-duration storage is similar to the draft. The modelled construction of long-duration storage infrastructure is back-ended to 2030, and the 10-Year Plan shows that AEMO Services will tender earlier to test cost assumptions and mitigate delivery risk associated with lead times.
• Firming infrastructure: the final Development Pathway for firming has changed compared to the draft. Consistent with notice to market associated with Tender Round 2, the firming target increased from 375 MW to 930 MW, with 1,075 MW ultimately awarded. There is now no additional modelled requirement until the mid-2030s.

Updates since the Final 2023 IIO Report

• Two important updates have been issued since the Final 2023 IIO Report was published, related to the Q2 2024 and Q4 2024 generation infrastructure tenders. You can find the latest update here.

The 2023 IIO Report shows over 46% of the minimum objective has been achieved for generation with 15,600 GWh / 5,790 MW added since November 2019. Outcomes from Tender 1 and 3 have helped in securing almost 600 MW, of the 2 GW minimum for long-duration storage. Separately, Tender 2 has secured 1 GW of new firming capacity, which increases system reliability, particularly in the short term.
