NEM spot prices fell 39.3 per cent week-on-week to average $57.08/MWh, a sharp decline driven by mild autumn weather and high renewable output. This collapse in wholesale prices creates a stark contrast with long-term demand forecasts. AEMO data shows data centre electricity consumption has doubled to 600 MW in four years, with projections for a fivefold increase to 25 TWh by 2035. Despite this anticipated surge, current wholesale and ASX futures markets show no immediate price response, highlighting a disconnect between near-term supply abundance and future demand pressures.
To meet this future demand, major grid augmentation is moving forward. Transgrid has proposed a $3.5 billion transmission project to connect inland renewable energy zones and Snowy 2.0 with coastal load centres in New South Wales. The project aims to complete a high-voltage loop, resolving critical bottlenecks that currently constrain energy flows. On the construction front, an Australian-developed wind turbine footing design is seeking a commercial partner to pilot a technology that could cut concrete use and reduce build times by 20 weeks, promising to lower capital costs for future projects.
Alongside electrification, the role of gas is being fundamentally reassessed. The Grattan Institute is urging greater investment in biomethane and hydrogen to decarbonise industrial processes where direct electrification is not feasible. This call comes as AEMO forecasts a 40 per cent drop in east coast gas demand. Separately, with analysis showing Australian domestic gas consumption has already peaked, advocates are pushing for a national ban on new residential gas connections to accelerate the household transition and protect consumers from rising fuel costs.
While national decarbonisation frameworks are debated, state policies are diverging. The Queensland LNP government has withdrawn from a national agreement to standardise carbon emissions data for transport infrastructure. This move follows the state's recent abandonment of legislated transport emissions reduction targets. In contrast, the New South Wales government is injecting another $225 million into its low-carbon manufacturing program. The funding aims to build local supply chains for products and materials essential for the energy transition.
On the grid, the impact of new technology is becoming more apparent. Queensland's coal-reliant grid saw record renewable generation on the last day of autumn, driven by strong wind, solar, and battery output. This highlights the growing capability of firming technologies to displace thermal generation. The trend is now industry standard, with most wind farm developers including battery storage in their project plans. Meanwhile, AGL is exploring new value streams by partnering with subscription service Karmo to manage its EV fleet and pilot vehicle-to-grid technology.
Building these domestic capabilities requires secure supply chains. A joint UNSW and ARENA report suggests Australia could establish a competitive polysilicon industry, leveraging cheap renewables and high ESG standards to compete with global incumbents. The challenge is scale, as highlighted by market leader JinkoSolar, which shipped 86.8 GW of modules in 2025 alone. The scale of global investment was also underscored by European Energy securing up to €228 million in German funding for a major hydrogen project in Denmark, illustrating the international capital flows shaping the transition.
The market operator is now grappling with the technical implications of this evolving grid. AEMO is seeking feedback on its draft 2026 General Power System Risk Review and new guidelines for System Restart Ancillary Services, with submissions for both closing in late June. It has also opened consultations on addressing premature voltage transformer failures in Queensland, with responses due in August.
