POWER provider EnergyAustralia has been fined $20,000 for an event that occurred at its Hallett Power Station during a time of skyrocketing prices.
A review by the Australia Energy Regulator — which occurs whenever prices exceed $5000/MWh — found that the company increased output on January 13 last year contrary to instructions from the Australian Energy Market Operator.
An imbalance between supply and demand affects the system’s frequency and can lead to power outages.
“System security may be compromised when dispatch offers made by generators are not accurate and where generators fail to comply with dispatch instructions given by the AEMO,” Australian Energy Regulator board member Jim Cox said.
“The reliable supply of electricity to consumers depends upon the power system being operated in a secure manner.”
The Canowie-based Hallett Power Station, 210km north of Adelaide, is a gas-fired generator that has capacity of 203MW — approximately 5 per cent of SA’s energy needs on a typical day.
A spokeswoman for EnergyAustralia said the company fully co-operated with the AER during the investigation and accepts its findings.
“We’ve reviewed and updated our operating procedures and are applying what we’ve learned by providing personnel with additional compliance training,” she said.
