The Queensland LNP has proposed a review and suspension of major transmission upgrades, a policy energy experts immediately warned could jeopardise grid stability and risk future blackouts. The controversial plan lands as the NEM grapples with shifting supply dynamics, with average spot prices falling 7.5 per cent week-on-week to $47.83/MWh on the back of a 46.2 per cent renewables share. The proposed pause on projects like Copperstring 2.0 creates a stark political dividing line on the infrastructure needed to manage the state's energy transition.
In a dramatic demonstration of grid resilience, Fortescue’s Pilbara network maintained stability using only solar and battery storage after a bushfire caused a major transmission failure. The system operated without any fossil fuel-based synchronous generation, an event engineers described as previously thought impossible. This real-world test of an inverter-based grid provides a powerful counter-narrative to arguments about the indispensability of traditional thermal plants for system strength. The experience mirrors that of Ukraine, where officials report solar and battery systems are now providing essential backup power for hospital intensive care units during grid outages.
Meanwhile, federal support for key network links continues, with the Clean Energy Finance Corporation providing financial backing for a contentious Tasmanian transmission project essential for the Marinus Link. The federal underwriting is designed to lower the ultimate cost passed on to consumers. Project momentum is also accelerating at the storage level. A landholder-led four-hour big battery received federal environmental approval in just over four weeks, clearing a major hurdle for its construction timeline. In Western Australia, a remote First Nations community secured a permit for its Sun Turtle solar and battery hub, which includes a 3.25 MW battery to reduce diesel reliance.
Major utilities are now integrating storage as a core part of their commercial strategy. AGL Energy expects a 10 per cent portfolio return boost from integrating its Liddell and Tomago battery systems with its existing coal-fired generation assets. This highlights the increasing value of storage for firming and arbitrage in a volatile market. The commercial case is sharpening against a backdrop of international market shifts. EU day-ahead markets saw negative-price hours more than double in Q1 2026, a Ricardo report found, driven by renewable surpluses in Spain, Portugal and Greece. This serves as a clear signal of the market imbalances Australia must manage as solar and wind penetration grows.
Global storage deployment is set to accelerate significantly, with BloombergNEF forecasting 158 GW of installations in 2026, a 41 per cent increase on last year's record. This global manufacturing scale-up will continue to influence local project economics. In the background, Australian regulators are refining market frameworks for this new reality. AEMO has opened consultations on real-time data provision and election procedures, signalling the detailed work underway to adapt NEM governance for a grid dominated by renewables and storage.
