With the receipt of the 5.3.4A letter from Powerlink and AEMO, the Eurimbula Hybrid Facility – a 1,226MW Export/666MW Import hybrid Renewbale project – has reached a critical milestone on its path to delivery, marking the transition into the next phase of project execution.

International renewable energy developer Elements Green has received formal technical clearance for grid connection for its Australian flagship project. The 5.3.4A letter, issued on 14 May 2025 by transmission network operator Powerlink and market operator AEMO, outlines the technical conditions for connection to the grid – a prerequisite for connection to the Powerlink network, final negotiations with offtake partners, EPC contractors and project investors.

The project comprises 2 x 348MW Solar PV (DC) and 2 x 333MW (2Hr) grid-forming BESS, making it the largest hybrid project in the country to achieve AEMO 5.3.4A approval, and importantly with gridforming inverter capabilities. The project is located within the proposed Central Queensland Renewable Energy Zone (REZ), approximately 50 kilometres southeast of Gladstone, and benefits from strong solar irradiation, grid infrastructure proximity and supportive regulatory conditions. “Securing the 5.3.4A letter brings us significantly closer to breaking ground this year,” said Toby Roberts, Country Director Australia at Elements Green. “We are now focused on completing the remaining approvals to enter the construction phase as planned. We are grateful of the technical work from our key partners at EPEC and SMA and the continued support from Gladstone Regional Council and the Queensland State Government in the development of this project cannot be underestimated”.

Additionally, the Eurimbula project is part of a grant-funded research programme supported by the Australian Renewable Energy Agency (ARENA). In partnership with the University of Queensland, EPEC, SMA, AEMO and Powerlink, the project will demonstrate through hardware-in-the-loop testing how hybrid facilities can support and strengthen future power system security

Eurimbula as a strategic anchor project in EG’s global portfolio

Eurimbula marks Elements Green’s first development in the Australian market and reflects the company’s ambition to deliver large-scale clean energy infrastructure across the Asia-Pacific region. As the country’s largest hybrid energy project to date, the Eurimbula Hybrid Facility is strategically embedded within EG’s global development pipeline of over 14 GW. This includes the Staythorpe Hybrid Project (>1 GWp PV, 360 MW BESS) in the United Kingdom and several recently approved storage assets across Europe.
