SA electricity crisis: It cost $4.5 million to keep power stable for a day, Australian Energy Regulator report shows

SOUTH Australian power consumers have been slugged for a massive $4.5 million price spike for services that stop energy infrastructure from blowing up.

The Australian Energy Regulator released a report on Tuesday night into why prices for services which stabilisethe grid exceeded $5000/MWh in SA on October 18 last year.

It found that for more than five hours, the cost of the services which regulate frequency soared to more than $11,000/MWh, bringing the total cost for the day to $4.5 million.

“In comparison, FCAS (Frequency Control Ancillary Services) costs across all mainland National Electricity Market regions combined are typically around $200,000 per day,” the report stated.

Over the week inclusive of October 18, 40 per cent of the cost — or $1.8 million — was paid for by customers and 60 per cent of the cost was recovered from generators, which The Advertiser understands tended to be wind farms because they cause frequency changes.

The report found that a planned outage on the Heywood interconnector, which connects SA to Victoria, created a risk that SA could cut off from the rest of the network. This creates a higher risk of blackouts.
