National Electricity Market spot prices surged 37.9 per cent week-on-week to average $143.36/MWh, sustaining the extreme volatility that has gripped the grid since the recent wind drought. The sustained price pressure underscores the market’s sensitivity to variable renewable output and thermal generation availability, creating a challenging environment for traders and large energy users navigating the supply crunch.
This market stress contrasts with a cautious policy landscape. The New South Wales pre-election budget delivered few major new investments for the energy transition, focusing instead on targeted cost of living relief. At the federal level, analysis revealed four of the government's signature Future Made in Australia programs were casualties of the May budget. Simultaneously, the government faces a landmark climate case from ten claimants alleging that continued coal and gas project approvals violate fundamental human rights, adding legal pressure to its fossil fuel policies.
Despite policy headwinds, major infrastructure projects are reaching critical milestones. In Victoria, Engie fully commissioned the Goorambat East Solar Farm, now the state's largest operating solar installation. The project notably used autonomous robotic technologies during construction. Meanwhile, Transgrid announced its EnergyConnect interconnector is now fully energised, a significant step toward integrating renewable zones and lowering power costs across three states by improving transmission capacity.
The energy storage sector is providing a vivid illustration of the transition's dual realities of technical success and commercial strain. In Western Australia, AEMO reports residential batteries are successfully flattening the solar duck curve on the SWIS, mitigating minimum demand risks and paving the way for the state's planned coal exit. Yet, the commercial landscape remains difficult. Wärtsilä is transferring its energy storage division into a joint venture, citing intense competition and low margins. The move comes even as the Finnish company delivers the 850 MW / 1680 MWh Eraring battery in NSW.
Innovation in storage technology continues to accelerate, driven by efforts to diversify beyond lithium-ion chemistries. CATL is advancing the energy density of its sodium-ion batteries for both stationary and vehicle applications. Moonwatt has debuted a modular sodium-ion system for utility-scale solar, while ZincFive is pursuing a SPAC merger to fund its nickel-zinc battery manufacturing for data centres. These developments signal a growing market for alternative chemistries tailored to specific grid and industrial needs.
This push for integrated solutions is timely. European grid operators are already warning that solar deployment is slowing due to network constraints, a cautionary tale for Australia's own renewable buildout. Locally, the focus turns to regulatory processes that will shape future grid investment. Submissions on AusNet’s application to recover costs from the January bushfires and AEMO’s consultation on transmission capacity constraints will be key indicators of the regulatory path forward.
