Total grid-scale batteries operated, contracted or in delivery includes battery assets where AGL has operational control or virtual or physical offtake or nomination rights, in proportion to AGL’s share of those rights. Battery assets are included from the date of execution of the EPC contract or offtake agreement.

Grid-scale batteries installed and managed represent the battery capacity within AGL’s portfolio that AGL owns and manages, or for which AGL has a contracted right to control dispatch. The metric excludes assets that are under development, contracted but not yet installed, or where AGL does not have ownership or dispatch control.

Capacity includes grid‑scale battery assets with capacity ≥ 30 MW. Capacity is based on the maximum capacity as published by the Australian Energy Market Operator (AEMO). Capacity is as at 30 June for the reporting year. Data excludes behind‑the‑meter battery assets, and other battery assets included in AGL’s Virtual Power Plant (VPP).
