Record generation from grid-scale renewables and rooftop solar is triggering wholesale energy prices and greenhouse emissions to fall, according to AEMO’s latest quarterly analysis of Australian energy markets.

The Quarterly Energy Dynamics report for the last quarter of 2023 shows that new records are being set for the amount of renewable energy being fed into the grid, reducing the reliance on traditional coal-fired generation.

AEMO CEO, Daniel Westerman, said wholesale electricity prices on the east coast have halved from 2022 levels, reflecting the increasing role that low-cost renewables are playing in daily generation.

“More low-cost renewable energy was generated and wholesale energy prices have fallen – a record number of times to zero, and beyond, into negative territory,” Mr Westerman said.

Wholesale electricity prices in the National Electricity Market (NEM) averaged $48 per megawatt hour (MWh) in Q4 2023, which is a drop of 24% from Q3 2023 and down 48%, or half, from Q4 2022. Contributing to the falling electricity prices was record generation output from grid-scale renewables, rooftop solar, together with lower prices for thermal coal.

With the right energy storage, like batteries and pumped hydro, the benefits of free and low-cost energy can be spread further across the day.

“The right storage means we can charge batteries and pump water up hills in the middle of the day when prices are low, and that energy can be released back into the grid during the evening peak when people get home from and school and work.”

Wholesale gas prices in the east coast market also continued a downward trend during the fourth quarter.

East coast wholesale gas prices averaged $10.83 per gigajoule (GJ), which is significantly lower than Q4 2022's $17.79/GJ, though slightly higher than $10.41/GJ in Q3 2022.

In Western Australia's Wholesale Electricity Market (WEM), a severe heatwave drove electricity demand to a record of 4,046 megawatts, pushing electricity prices higher.

The average wholesale electricity price increased for Q4 2023 – rising to $83.83/MWh, up 15% compared to Q4 2022, but lower than historically high prices observed in Q2 and Q3 2023.

..this gives the impression that wind & solar produces 24/7......& yet record high prices for the consumer & only going to get worse.

The solution , reduce wind & solar & let coal run like it used to ...effeciently.

Solar & wind shoul dbe legislated to produce plate 24/7 & not given a free pass...that then requires a back up.

I can ride a bike down a hill at 100 km/h..therefor I don't need a car.......that is your system...works well when factors are aligned...just cant keep going for teh long run.

& then is NO cheaper alternatives...battery & pump hydro hideously expensive for the gap.

Nuclear is the cleanest , cheapest, saftest tech we have, that is scaleable.
