Eku Energy's 10-hour Griffith battery faces federal review amid local objections in NSW

Eku Energy's Griffith battery project, a 100 MW / 1000 MWh (10-hour duration) battery energy storage system proposed for outside Griffith, NSW, has entered the federal environmental approval queue while facing a second state-level review due to local objections. The project was originally an 800 MWh (8-hour) battery that won underwriting through NSW's Electricity Infrastructure Roadmap in 2023. One local objector described it as "evil, poisonous and treacherous." The battery would be co-located with existing and planned solar farms.
