Batteries Displace 24PJ of Gas-Fired Generation Demand in Eastern Australia, IEEFA Says
Eastern Australia burned 6% less gas in FY2025-26 than in calendar year 2024 once the LNG sector is stripped out, IEEFA reported. The institute attributes a fall of more than 24PJ in gas demand for power generation over a single year to more electricity coming from grid-scale battery storage.
Production available to local buyers shrank alongside consumption. Year on year for the first half, IEEFA put domestic supply at 214PJ against 231PJ previously, a contraction exceeding 7%.
Local buyers are also taking a thinner slice of what the region produces. IEEFA calculated the domestic market's share of domestic gas production at 23% in the first half, against 25% twelve months before, and described that as the weakest reading since at least 2019.
Queensland's export flows over the same half-year came to nearly 645PJ, with a further 61PJ consumed by exporters to operate their facilities, IEEFA said.
One export venture accounts for a long-running draw on local molecules. Since 2017, GLNG has, in IEEFA's word, "siphoned" more than 1000PJ out of the domestic market, a volume the institute equates to over two years of domestic demand.
The Australian federal government is drafting a gas reservation policy aimed at securing adequate domestic supply and pushing prices down. That work is under way while both domestic consumption and domestic supply contract and the domestic call on production sits at its lowest share in the period IEEFA examined.
The generation number matters most for anyone sizing future domestic gas need. IEEFA ties the 24PJ reduction directly to battery output replacing gas-fired supply.
