New South Wales has launched its most ambitious clean energy procurement to date, opening tenders this week for a massive 2.5 gigawatts (GW) of new renewable generation capacity and an unprecedented 12.5 gigawatt-hours (GWh) of long-duration energy storage. Announced on May 20, 2026, by AusEnergy Services Limited (ASL), the NSW Consumer Trustee, these tenders represent a critical step in the state’s transition away from coal-fired power and towards a more resilient, clean electricity grid.

The scale of this procurement is significant, aiming to underpin the reliability of the National Electricity Market (NEM) as major coal generators, such as Eraring Power Station, prepare for closure by April 2029. The tenders are designed to accelerate the deployment of dispatchable power and storage solutions, crucial for maintaining grid stability and putting downward pressure on electricity prices for NSW households and businesses.

The Drive Behind the Record Tenders

The NSW Electricity Infrastructure Roadmap outlines the state’s plan to deliver an affordable, clean, and reliable energy system. A key component of this roadmap is the development of Renewable Energy Zones (REZs) and the strategic procurement of new generation and storage to replace retiring thermal assets.

Forecasts from the Australian Energy Market Operator (AEMO) have consistently highlighted the need for significant new capacity to avoid supply shortfalls, particularly during peak demand periods. The latest tenders directly address these projections, seeking to secure power for the long term.

“Tender 8 alone will deliver enough energy to power about one-third of homes in NSW, marking a major step forward in our plan to future-proof NSW’s electricity system,” said NSW Energy Minister Penny Sharpe.

Tender 8: Boosting Renewable Generation

Tender 8, the state’s largest generation Long-Term Energy Service Agreement (LTESA) tender yet, aims to secure 2.5 GW of new renewable energy generation. This tender introduces a new hybrid generation LTESA, specifically designed to support the growing number of combined solar or wind generation and battery storage projects in development.

Projects participating in Tender 8 must have a minimum capacity of 30 megawatts (MW), with those on track to commence operations before the end of 2029 considered more favourably. This aggressive timeline underscores the urgency of integrating new renewables into the grid.

Tender 9: Unlocking Long-Duration Storage

Perhaps the most striking aspect of the new procurement is Tender 9, which seeks up to 12 GWh of long-duration energy storage. This capacity is critical for the grid, allowing excess renewable energy generated during periods of high sun or wind to be stored and then dispatched when needed, such as during evening peaks or periods of low renewable output.

These storage projects are expected to include large-scale batteries and pumped hydro, with successful projects requiring a minimum power capacity of 5 MW and at least eight hours of energy storage capacity. The operational target for these projects is by 2034.

The focus on long-duration storage is essential for grid stability, providing the flexibility needed to manage the intermittency of solar and wind power. This contrasts with shorter-duration batteries, which primarily offer frequency control and rapid response services.

The Role of ASL and Market Mechanism

AusEnergy Services Limited (ASL), acting as the NSW Consumer Trustee, is responsible for conducting these tenders under the NSW Electricity Infrastructure Roadmap. ASL’s role is to ensure the procurement process delivers value for NSW electricity customers. The LTESA revenue support mechanisms offered are designed to improve project bankability, helping developers reach final investment decisions and financial close.

This streamlined approach aims to reduce administrative burden for bidders while maintaining competitive tension, similar to the federal government’s Capacity Investment Scheme.

Impact on the Energy Landscape

These tenders will have a profound impact on the future energy landscape of NSW and the broader NEM. By securing substantial renewable generation and long-duration storage, the state aims to:

  • Enhance Grid Reliability: Ensure a stable and secure electricity supply as coal plants retire.
  • Reduce Emissions: Accelerate the transition to a low-carbon energy system.
  • Stabilised Prices: Increase competition and reduce reliance on volatile fossil fuel markets, potentially leading to lower wholesale electricity prices.
  • Economic Opportunity: Drive significant investment and job creation in regional NSW, particularly within the designated REZs.

Registrations for both tenders are scheduled to close towards the end of June 2026, with the announcement of successful bids expected by late 2026. This rapid timeline highlights the government’s commitment to expediting the energy transition.

For households looking to manage their energy consumption and potentially participate in a more dynamic grid, understanding how these large-scale changes affect the market is crucial. While these tenders focus on utility-scale projects, the increasing integration of renewables and storage can influence wholesale prices, which ultimately flow through to retail offers.

This significant investment in both generation and storage capacity is a clear signal of NSW’s determination to build a robust, renewable-powered future, providing a blueprint for other states navigating similar energy transitions.
