CMCRC’s MQD tool shows financial impact of Hazelwood Power Station closure

The release of the ACCC’s Retail Electricity Pricing Inquiry report has put the issue of electricity pricing back in the spotlight. The CMCRC Energy Centre of Excellence has already published findings in this field.

Energy is a hot topic in Australia. From usage to sustainability, it is an issue that affects individuals and communities like few others. In this broadly contentious area, the question of energy prices is particularly charged.

In July 2018, the Australian Competition and Consumer Commission (ACCC) released its long-awaited Retail Electricity Pricing Inquiry report. In it, the watchdog makes 56 recommendations that it says “will save the average household between 20 and 25 per cent on their electricity bill, or around $290 to $415 per annum.”

Impact of Hazelwood power plant's withdrawal

With small-to-medium businesses also predicted to save 24 per cent on their electricity bills each year, the report’s findings have generated plenty of attention.

Although our data was not used in the ACCC report, CMCRC has already shown how events in the energy market can impact electricity prices.

In 2016, the proposed closure of Hazelwood Power Station in Victoria was widely covered in the media, with feverish speculation around potential price increases. But it has taken CMCRC’s world-leading infrastructure and research expertise to show the full impact of the closure.

CMCRC Energy Centre of Excellence makes the connections
Hazelwood finally closed on 1 April, 2017. Dr Jeff Wong, Head of the CMCRC Energy Centre of Excellence, assisted by researcher Lin Han, used the Market Quality Dashboard (MQD) to examine the data before and after the closure. By doing this, they could determine its impact.

“The closure of Hazelwood certainly seems to have had an impact on Victoria’s generation capacity, with a knock-on effect on electricity prices in Victoria and its interconnected  states,” said Dr Wong.

“In the months following the closure, we clearly and consistently see higher wholesale electricity prices in Victoria, New South Wales and South Australia, after controlling for relevant factors such as demand, monopolistic characteristics, price volatility, generation capacity and surpluses from connected states.”

The CMCRC Energy Centre of Excellence is one of four such centres within CMCRC – the others being Finance, Health and Digital Currency.

“Jeff and Lin’s work epitomises what we’ve been doing at CMCRC for almost 20 years,” said Group CEO David Wright. “We work collaboratively with our industry and university partners to apply academic research to solve industry challenges and deliver commercialisable outcomes. In the process, we also develop the next generation of R&D leaders to keep growing the capability of our industry partners.

“Add to that our infrastructure and the tools like MQD, which builds on all the technological innovations we’ve developed over time, and it’s a win-win situation for our partners, our researchers and the economy.”
