The operator of the 150 MW/193 MWh Hornsdale Power Reserve in South Australia has been fined AUD 900,000 ($620,470) for failing to provide essential services to maintain the stability of the grid.
Hornsdale Power Reserve (HPR), which is owned and operated by French renewable energy giant Neoen, has been ordered to pay a AUD 900,000 fine for breaching Australian power rules.
The fine, ordered by the Federal Court, comes after the Australian Energy Regulator brought legal action against HPR. It is related to breaches of the National Electricity Rules, involving backup contingency services for the grid.
The regulator claims that between July and November 2019, HPR failed to provide contingency frequency control ancillary services (FCAS), despite making offers and receiving payment from the Australian Energy Market Operator (AEMO) to be on stand-by to provide them. HPR admitted that it would have been unable to comply with its offers and provide those services during that period, despite being paid to do so.
The failure was identified when an unexpected outage at the coal-fired Kogan Creek power plant in Queensland in 2019 caused grid disturbances. The court heard that investigations after the Kogan Creek incident had revealed that the battery, also known as the Tesla big battery, had been under-delivering on promised stability services since technology provider Tesla had performed a firmware update earlier in 2019.
