Eku Energy has secured a NSW long duration storage long-term energy service agreement from AEMO Services.  The agreement is for a 100 MW/ 800 MWh Griffith battery energy storage system (BESS) in Yoogali, within the Griffith local government area (LGA) of New South Wales. 

The project will provide an eight-hour-duration storage capacity to store excess renewable energy and dispatch it during periods of high demand. Furthermore, the project will also provide efficient integration into the existing electricity network. It has the capacity to serve over 88 per cent of the daily electricity demand from the Griffith LGA. The project is expected to become operational in 2028. 

Eku Energy is a global, technology-enabled developer working exclusively on BESS. It operates across the full project cycle, including the development, construction, and management of energy storage assets. The company is jointly owned by a fund managed by Macquarie Asset Management and the British Columbia Investment Management Corporation.
