EconomyAustralia’s reliance on gas generation during evening peak falls by almost 70%

EnergyEdge says gas generation between 5pm and 8pm fell 67% in the year to August as utility-scale and household batteries expanded. Batteries supplied 49% of dispatchable power during the August 2026 evening peak, up from 0.4% in 2020, while gas’s share fell to 20.6%. Lower wholesale prices benefit households but may complicate investment in backup gas capacity.
