Akaysha Energy, a leading Australian developer of grid-scale battery energy storage systems (BESS), has secured a corporate debt facility worth A$300 million (approximately USD 197 million) to fuel the next phase of its global expansion. The funding will support the construction and development of Akaysha’s rapidly growing pipeline of battery storage projects across Australia, the United States, Japan, and Germany.

Strengthening the Backbone of the Clean Energy Transition

As demand for clean, reliable energy grows globally, storage solutions are increasingly vital to support the shift to renewable energy. Unlike fossil fuels, renewable sources such as wind and solar are inherently variable, producing power based on weather conditions rather than consistent output. Battery storage bridges this gap by ensuring energy can be captured, stored, and delivered when needed, reducing waste and strengthening grid stability.

Akaysha’s projects are designed to address this critical need. Since its founding in 2021, the company has focused on engineering large-scale energy storage systems capable of managing high-capacity grid operations. It recently commissioned the initial 350 megawatts of its 850 MW Waratah Super Battery, which is currently among the world’s largest and most powerful battery storage systems.

A Pioneering Financial Structure in the Australian Renewables Market

The newly secured loan facility is structured as a borrowing base loan, a financing mechanism that allows the loan size to increase in tandem with the value of Akaysha’s operational and development-stage battery projects. While borrowing base loans are familiar in the United States, particularly in oil and gas as well as renewable energy markets, this marks the first time such a structure has been deployed within the Australian clean energy sector.

The facility provides flexibility and growth potential, offering Akaysha the capacity to respond quickly to evolving energy needs and expand its global footprint. As energy demand surges due to electrified transportation, data centres, and increased grid pressure, battery storage providers like Akaysha are playing an increasingly central role in managing energy security and reliability.

Backed by BlackRock and Leading Global Banks

Akaysha Energy has been part of BlackRock’s Climate Infrastructure portfolio since 2022, following its acquisition by BlackRock Real Assets. The investment was the firm’s first battery storage play in the Asia-Pacific region and reflects BlackRock’s broader commitment to backing scalable climate solutions that can generate long-term value while advancing decarbonisation.

The debt facility was arranged with the support of a global syndicate of banks including BNP Paribas, Deutsche Bank, ING, SMBC, and Westpac. The involvement of such major financial institutions underscores growing investor confidence in battery storage as a viable and lucrative component of the clean energy value chain.

Accelerating Deployment of Storage Capacity Across Key Markets

Andrew Wegman, Akaysha’s Chief Financial and Investment Officer, described the deal as a significant milestone for both the company and the wider Australian renewables sector. He noted that the loan structure offers the scalability and agility needed to accelerate project timelines and seize emerging market opportunities across Akaysha’s global development pipeline.

The company’s focus on scaling battery storage infrastructure is timely, particularly in markets where clean energy penetration is high but grid stability remains a challenge. With the new financing in place, Akaysha is poised to deliver more transformative projects that contribute directly to national energy targets and climate goals.
