Akaysha Energy Secures A$1.75 Billion Financing for Australian Battery Storage

Australian battery storage developer Akaysha Energy has secured an A$1.75 billion portfolio-level financing facility to refinance existing project debt and support the next phase of its large-scale battery energy storage system (BESS) development. Announced on 20 October 2026, the transaction combines financing across four Australian battery projects into a single structure, giving the company greater flexibility to expand across the National Electricity Market (NEM).

The financing is backed by a consortium of 11 international and Australian banks and covers the Brendale, Orana, Ulinda Park and Elaine battery storage projects. The deal comes as Akaysha expands its operating portfolio and advances a development pipeline of about 6 gigawatts (GW) of power capacity and 25 gigawatt-hours (GWh) of energy storage. The transaction primarily restructures existing project-level financing rather than representing an entirely new A$1.75 billion investment in additional battery capacity.

 

A$1.75 Billion Facility Consolidates Battery Project Financing

 

The new financing arrangement replaces separate project-level debt facilities with a portfolio-level structure covering multiple operating and development-stage battery assets. It comprises three financing facilities with tenors of five, seven and ten years, alongside revolving liquidity and contingent instrument facilities. These arrangements are intended to provide Akaysha with greater financial flexibility as it manages existing obligations and develops additional projects.

Portfolio financing lets developers manage funding across multiple assets rather than arranging separate debt structures for each installation. For Akaysha, this approach could simplify financial management and provide a more scalable funding framework as its battery portfolio grows. Andrew Wegman, Managing Director and Chief Financial & Investment Officer at Akaysha Energy, said, "As well as refinancing our existing operating and construction assets, this portfolio-level facility gives us the flexibility to accelerate our next wave of projects while we continue deploying capital where we see the strongest opportunities across the pipeline."

Four Australian Battery Projects Included in Refinancing

 

The financing covers three operational battery storage assets and one project under construction. Brendale and Ulinda Park are located in Queensland, while Orana operates in New South Wales. The fourth project, Elaine BESS in Victoria, began construction in October 2025 and is scheduled for completion in the second half of 2027. Bringing these projects together under one financing structure allows Akaysha to manage assets at different stages of development within a common funding framework.

According to participating lender Deutsche Bank, the four projects represent approximately 1,086 MW of battery storage capacity. The refinancing follows Akaysha's continued expansion of its operational assets, including Orana, which is expected to reach commercial operation in June 2026. The company's separate Waratah Super Battery in New South Wales has also recently reached final commercial operation, although Waratah is not included in the new portfolio financing.

 

Eleven Banks Support Long-Term Energy Storage Investment

 

The transaction was supported by ANZ, BNP Paribas, Bank of China, CIBC, Commonwealth Bank of Australia, Deutsche Bank, DNB, ING, Mizuho, MUFG and Rabobank. Participation from the international banking consortium reflects lender interest in financing large-scale battery storage infrastructure as Australia's electricity system incorporates more renewable generation.

Deutsche Bank participated as an original lender and mandated lead arranger, including in the longer-tenor financing tranches. Longer-term debt arrangements can matter for energy storage developers because battery projects require significant upfront capital, while revenues and operating performance develop over several years. The financing structure also provides liquidity facilities intended to support portfolio management and the company's broader development activities.

Financing Supports Approximately 25 GWh Battery Development Pipeline

 

Akaysha's Australian development pipeline comprises approximately 6 GW of planned power capacity and 25 GWh of energy storage across the National Electricity Market. These figures represent prospective projects rather than completed installations or capacity funded entirely by the latest transaction. The new financing platform is intended to support Akaysha's ability to progress this pipeline as projects advance through development, construction and commercial operation.

Large-scale battery systems are becoming increasingly important to Australia's energy transition as the electricity network accommodates higher shares of solar and wind generation. Storage facilities can absorb electricity when supply is abundant and discharge it during periods of higher demand, helping manage fluctuations in renewable output and providing flexibility to the grid. However, the commercial success of individual projects depends on factors such as electricity market revenues, operating performance, network requirements and financing costs.

 

Portfolio Financing Marks a Shift in Battery Infrastructure Funding

 

The transaction shows Australia's battery storage industry moving beyond financing individual projects to structures that can support larger portfolios of operating and construction-stage assets. As developers expand their pipelines, access to long-term debt and flexible funding arrangements can become increasingly important for maintaining investment capacity and managing financial risks.

Akaysha's financing also follows the completion of several major battery projects, strengthening its position in Australia's utility-scale energy storage market. The next stage will depend on completing Elaine BESS, progressing additional projects and demonstrating that the portfolio structure can support further growth.

The A$1.75 billion facility establishes a financing platform for Akaysha's existing assets and future expansion, but it should not be interpreted as an equivalent amount of newly committed project construction expenditure. Its broader significance is demonstrating institutional lender participation in large-scale battery storage infrastructure as Australia continues to expand its renewable electricity system.
