The partnership marks a significant milestone in Avenis Energy’s development pipeline of generation and storage projects across the Australian east coast. Once constructed, these projects would increase the reliable, dispatchable capacity across the National Electricity Market helping accelerate Australia’s clean energy transition. Each project would be capable of powering over 190,000 households for 4 hours improving network resilience at time of low solar or wind generation.

“Collaborating with Altenso gives us a bankable technology partner with deep engineering expertise to work with us in delivering the Moree and Deniliquin Projects,” said Imran Sheikh, Managing Director Commercial, Avenis Energy. “Appointing a battery integration partner is another crucial step forward for us to getting both projects into construction next year.”

“We are looking forward to building our footprint in Australia with Avenis Energy. Their experience and long-term orientation in project development makes us confident that we will execute this project successfully. Both, the Moree and the Deniliquin Project will definitely mark a cornerstone in Australia’s clean energy transition,” said Dr.-Ing Enrique Garralaga, Managing Director Engineering at SMA Altenso.

After a two-year construction period, commercial operation is expected for 2028

Altenso and Avenis Energy expect to start construction on both projects by mid‑2026 with the installation of battery containers and power‑conversion equipment planned between Q4 2026 and Q2 2027, followed by commissioning and grid‑compliance testing through 2027. Practical completion and full commercial operations are targeted for 2028.

State of the Art inverter technology by SMA is part of the project

Battery energy storage systems are a key component for the energy transition as they enable renewable integration, stabilize the grid and allow homes, businesses, and communities to store and use their own solar energy, reducing reliance on the grid, cutting emissions, and paving the way for a more distributed and sustainable energy system. SMA Altenso uses SMA‘s state-of-the art inverter technology featuring black-start capability, grid-forming technology and redundancy services. 

Altenso has been successfully implementing turnkey BESS projects around the world with a total output of more than 1.5 GW. In addition, the company’s track record includes over 1 GW of delivered power conversion units to hydrogen projects.
