Financial overview

2026 real AUD. Monetary values are CPI-adjusted to 2026 real Australian dollars. Greenfield capex uses AEMO benchmarks when plant-specific cost is unknown.

Notes
Eku Energy’s Griffith BESS is a proposed 100 MW / 800 MWh battery in Yoogali, expected operational in 2028. No project-specific greenfield capex announcement was found in the searched owner/government sources, so no plant-specific capex is populated. Operating cost defaults were used as a fallback; they are not project-specific.
