Record renewable generation drives Australian power prices down

Canberra, April 28 Record levels of renewable energy output has driven down Australia's wholesale power prices, according to an official report published on Friday.

The Australian Energy Market Operator (AEMO) said in its energy dynamics report for the first quarter of 2023 that demand from the national electricity market fell to its lowest level since 2005, reports Xinhua news agency.

Wholesale prices in the national electricity market averaged A$83 per megawatt-hour (MWh) between January and March, down from A$93 and A$216 in the previous two quarters.

The fall was largely attributed to significant increases in renewable output.

AEMO said the amount of electricity produced by rooftop solar systems nationwide was 23 per cent higher in the first quarter of 2023 compared to the same period in 2022.

Generation from large-scale wind and solar farms was also 11 per cent higher.

At the same time, energy generation from coal and gas declined, with the latter providing its smallest share of electricity supply for the first quarter of the year since 2005.

For the entire quarter, national electricity market emissions totalled 28.83 million tonnes of carbon dioxide equivalent a record low for the period.

Electricity generation is Australia's biggest polluter, accounting for approximately one-third of the country's emissions.

Daniel Westerman, chief executive of AEMO, said the data reflected the shift underway in Australia's electricity system as the country pursues a net zero emissions future.
