NEM spot prices soared 120 per cent week-on-week to average $154.59/MWh, extending a period of extreme volatility as winter demand continues to test grid resilience. The sustained price pressure is intensifying scrutiny of federal energy policy, with new analysis arguing the Labor government's flagship Capacity Investment Scheme has failed to deliver the required new generation. Critics now contend the CIS should be replaced with a Contracts for Difference model, warning that procurement delays are inflating systemic costs and risk prolonging the NEM's reliance on expensive diesel generation to maintain reliability.
The debate over investment mechanisms comes as international examples highlight alternative pathways. A review of Denmark’s successful energy transition suggests that attracting capital to Australian renewables requires reducing process risks and planning delays, rather than simply proving project financial viability. The Danish model underscores that providing developers with greater certainty on project delivery timelines is the critical factor in accelerating the phase-out of fossil fuels, a direct contrast to the hurdles facing many Australian projects.
Meanwhile, the market is already shifting underfoot, regardless of policy settings. Origin Energy reported a substantial decline in gas sales, citing weakening consumer demand and the growing displacement of gas-fired generation by utility-scale batteries. This marks a significant commercial inflection point, providing concrete evidence that battery storage is successfully competing with and capturing market share from legacy gas peaker plants, particularly during periods of peak demand and price volatility.
The role of storage in firming the grid is also evolving at the project level. Goldwind Australia’s managing director has proposed integrating dedicated battery storage with every new wind turbine to directly address grid stability challenges. This concept of embedded storage moves beyond co-location towards a more integrated design for renewable generation. At a smaller scale, the Clean Energy Finance Corporation is expanding its partnership with Westpac to provide discounted financing for businesses investing in rooftop solar, batteries, and electric vehicles, aiming to accelerate uptake of distributed energy resources.
The electrification of transport continues to gather pace, adding another layer of complexity and opportunity for the grid. Australian regulators have granted sales approval for a new compact electric SUV from Leapmotor, which is expected to enter the market priced below $35,000. The arrival of more affordable EVs will likely spur adoption, increasing pressure on distribution networks but also expanding the potential fleet of consumer energy resources. This transition unfolds against a backdrop of divergent state-level ambitions, highlighted by recent public appearances from the energy ministers of NSW and Queensland, who presented starkly different visions for their states' energy futures.
Looking ahead, AEMO is progressing its planning for future grid security and market design. The operator is now considering stakeholder feedback from its 2025 System Security plan as it begins work on the 2026 iteration. Several key consultations are also drawing to a close, with submissions due next week on proposed changes to the gas market parameters and the transportation service point register.
