The regulator expects no repeat of final yr’s wholesale vitality value spike as file photo voltaic era and controls on coal stabilise costs.
But the closure of AGL Energy’s Liddell coal-fired energy plant station will take away vital dispatchable capability from the nationwide electrical energy market, the Australian Energy Regulator (AER) warned.
AGL has begun the shutdown of Liddell’s three remaining era models – one this week, with the others scheduled for subsequent week.
“This will tighten the supply-demand balance, especially in evening periods when solar output is low,” the AER stated in a quarterly report.
The Liddell energy station website within the NSW Upper Hunter will grow to be an industrial hub, together with a commercial-scale battery to be constructed on the positioning, after greater than 50 years of producing electrical energy into the nationwide grid.
The AER report launched on Thursday confirmed wholesale vitality costs stabilised and solar energy era set one other file through the January to March interval.
But heatwave circumstances resulted in common costs being larger than they in any other case would have been.
Across the market, grid-scale photo voltaic output achieved a quarterly file and accounted for 9 per cent of the overall era combine.
Large-scale photo voltaic output elevated 11 per cent from its file excessive on the finish of 2022, reflecting sturdy funding in photo voltaic era.
Rooftop photo voltaic output additionally hit a file, as households lower payments and emissions, and contributed to downward strain on daytime costs.
“Forward base futures prices for electricity initially stabilised during the early part of 2023, and despite an increase in March they remain well below levels observed in 2022,” AER chair Clare Savage stated.
“It also appears that the coal price cap interventions continue to place downward pressure on electricity prices, together with strong renewable output.”
Helping to ease an anticipated tight gasoline provide this winter, southern gasoline storage refilled to its highest end-of-March-quarter degree since reporting started.
East coast gasoline spot market costs continued a downward pattern, after a short enhance in February, and averaged lower than $12 per gigajoule as worldwide costs ease.
Asian liquefied pure gasoline costs greater than halved in contrast with the December quarter, to lower than $20/GJ.
While gasoline era elevated through the quarter, it has remained at total decrease ranges than in recent times, the report stated.
Coal turbines in NSW and Queensland provided extra complete capability, most of which was provided at decrease costs, as coal output rose.
The regulator’s Default Market Offer for 2023/24, which controls what vitality corporations can cost prospects, will likely be launched by May 26.
