Upcoming Changes To Battery Liability

From 1 January 2026, new legislation will reduce compliance obligations for entities operating battery energy storage systems (BESS). Under the amendments to the Renewable Energy (Electricity) Act 2000 (the Act), electricity used for energy storage will no longer be considered a relevant acquisition.

We encourage you to review the following information to understand how the changes may impact you.

Key changes effective 1 January 2026

  • If you only report acquisitions for the purpose of energy storage you will no longer be required to submit an annual Energy Acquisition Statement (EAS) or surrender Large Scale Generation Certificates (LGCs) and Small-Scale Technology Certificates (STCs).
  • If you acquire electricity for purposes other than energy storage, you must continue to lodge an EAS.
  • Entities acquiring electricity used specifically for the purpose of energy storage in 2026 are no longer required to report or surrender certificates for that portion.
