[SMM Analysis: ACE Power's ESS Project Approved] Recently, the "Eastern Hub Stabilization Battery" project (1000MW/8000MWh) of energy developer ACE Power, located in the New England REZ of New South Wales, Australia, has received federal environmental approval. On June 18, the project was classified as a "non-controlled action" under the EPBC Act, exempting it from a comprehensive federal assessment and significantly reducing development risks. The total investment in this Battery Energy Storage System (BESS) is 1.6 billion Australian dollars, with a designed continuous discharge duration of 4-8 hours, primarily for energy arbitrage and long-term stable power supply. This approval further expands ACE Power's layout of large-scale ESS assets in Australia.
