NHOA Energy is proud to have officially commissioned the Blyth Battery. This enormous facility, with a capacity of 238.5 MW and 477 MWh, is located just south of Canowie in South Australia. This innovative and complex project attacks the hottest issue in NEM—the stability of the grid. Then there is the mighty battery. It’s more than just the new darling of energy storage and management.
NHOA Energy partners with EnergyAustralia and Enerven to deliver the Hallett Battery Energy Storage System (BESS) project. Their effort with us on this collaboration builds on their previous work on the Blyth Battery. This project will add 245 MWh of new energy storage capacity at the Hallett Power Station. Designed as a grid-forming solution, the Hallett BESS will contribute to frequency control and overall grid support while facilitating participation in NEM market services.
This was an important milestone paving the way for NHOA Energy’s ongoing efforts to bolster resilience of South Australia’s power system. Initially, the Hallett BESS will be used to deliver 50 MW of power. It will include five hours of battery storage and commissioning is scheduled to begin in January 2027.
The Blyth Battery and Hallett BESS projects in Ontario, Canada and South Australia respectively aim to enhance renewable energy integration. They prop up South Australia’s existing, failing power infrastructure. These interconnection projects will soon be indispensable to keeping the grid reliable. They’ll help the entire region’s transition to a more sustainable energy future by ensuring underserved communities fully benefit from it.
“We are proud to support EnergyAustralia in a project that combines advanced grid-forming technology with a strong institutional framework such as the Capacity Investment Scheme, while making smart use of existing infrastructure.” – Adrian Marziano, NHOA Energy Australia and Pacific VP
The Hallett BESS project is a smart use of existing infrastructure. It significantly increases the flow of local jobs and economic development it supports back in South Australia. For EnergyAustralia trading and transition executive Daniel Nugent, this initiative is a big deal.
“By building the battery at Hallett, we are making use of infrastructure that is already there, supporting local jobs and strengthening South Australia’s power system at the same time. Financial close means this project is real, funded and now being built, and our focus now shifts squarely to disciplined execution and delivery.” – Daniel Nugent, EnergyAustralia trading and transition executive
