Solar PV accounted for 70 per cent of global electricity generation growth in 2025, according to a landmark International Energy Agency report highlighting the technology’s new dominance. The IEA’s Global Energy Review found solar added 600 TWh of new output last year, with demand from electric vehicles and data centres rising 38 and 17 per cent respectively. This global surge in renewable-fed demand is mirrored locally, where NEM spot prices climbed 15.9 per cent week-on-week to $84.65/MWh. The price jump underscores the operational pressures facing the Australian grid, reinforcing the urgency behind the AEMC’s recent proposal for new data centre connection standards.
The challenge of maintaining grid stability amid this transition is driving significant infrastructure investment. In Queensland, Powerlink and Hitachi will install four synchronous condensers by 2029 to manage system strength as more renewables connect. The move provides a crucial stability service independent of thermal generation, even as the state government evaluates extending the operational life of its coal fleet through 2031. It highlights the engineering reality that retiring fossil fuels requires direct investment in new grid-firming technologies.
Australia's battery storage project pipeline continues to accelerate across all scales. In a major milestone for large-scale storage, Recurrent Energy secured grid connection approval for its 600MWh Sundown Energy Park, successfully clearing AEMO’s rigorous technical requirements. At the distributed level, Pacific Energy will deliver 81MWh of battery systems across the Northern Territory under a new contract with Territory Generation to bolster regional grid stability. The sub-5MW market also saw consolidation, with CleanPeak Energy acquiring specialist developer Sustainable Energy Infrastructure, signalling growing investor appetite for smaller commercial and industrial assets.
Momentum is also building in the domestic manufacturing and recycling sectors. An Australian energy storage designer secured a $2.3 million ARENA grant to help scale up its local manufacturing capacity. Meanwhile, a domestic start-up landed a $12 million funding boost to challenge China's dominance in EV battery recycling, with plans to process up to 4000 batteries annually for critical mineral recovery. Both investments reflect a growing policy and commercial focus on shoring up sovereign supply chains for the energy transition.
Regulators are racing to adapt market frameworks to these technological shifts. The Australian Energy Market Commission is consulting on proposed reforms to make gas network regulation fit for purpose as household electrification accelerates. The AEMC also released a draft determination concluding that current electricity planning rules are sufficient, pushing back on a rule change request from the Centre for Independent Studies. These actions run parallel to Senate hearings where advocates are calling for an urgent overhaul of Australia's petroleum resource rent tax to better capture revenue from high global LNG prices.
The global context offers a preview of Australia’s trajectory. Record-breaking negative power prices on the Iberian Peninsula, driven by high solar output, demonstrate the market volatility that accompanies deep renewable penetration. In the United Kingdom, the average purchase price for new EVs has now dropped below petrol equivalents, a key tipping point for transport electrification. These trends signal the increasing scale and complexity of the challenges Australian market bodies and project developers will navigate in the coming years.
