EnergyAustralia has paid AU$750,000 (US$519,300) in penalties after the Australian Energy Regulator (AER) alleged that four battery energy storage systems (BESS) it manages failed to deliver frequency services offered into the market.
EnergyAustralia has taken delivery of the final battery storage units for its 50MW/250MWh Hallett BESS in South Australia, as construction continues at the site.
