NEM average spot prices surged 60.7 per cent week-on-week to $88.13/MWh, a stark reminder of the grid’s sensitivity to fuel cost pressures. The spike coincides with a sharp revision in future gas price expectations. The ACCC’s 2026 netback gas price forecast jumped to $25/GJ from $15/GJ, following recent military actions in Iran. While east coast wholesale gas prices are currently stable between $8/GJ and $9/GJ, the forecast signals significant potential cost pressures for gas-fired generators and large industrial users heading into the medium term.
Wood Mackenzie analysis reinforces this global exposure, indicating persistent Middle East conflict could drive up generation costs by $8.30/MWh across major power markets through 2026. This underscores the growing strategic importance of insulating the domestic economy from international fuel market volatility. One report today highlighted Australia’s heavy reliance on imported nitrogen fertiliser as a key supply chain vulnerability. It argued that leveraging abundant local renewables for domestic production presents a clear path to mitigating this risk.
Amid the market volatility, the project pipeline continues to deliver significant new capacity. Spark Renewables secured final NSW planning consent for its Dinawan Energy Hub, a major hybrid project in the South-West Renewable Energy Zone. The facility combines an 800 MW solar farm with a 356 MW / 1,574 MWh battery, one of the larger storage systems to clear planning hurdles in the state. This approval follows last year’s record highs for wind and solar generation, where utility-scale batteries increasingly displaced gas peakers in the merit order.
Regulators are moving to address emerging grid challenges and manage the decline of legacy systems. The AEMC has proposed new technical standards for data centres connecting to the grid, releasing a draft rule to promote system security and enable faster connections for the power-hungry sector. In parallel, the commission is consulting on reforms to gas network regulation. The proposed updates aim to ensure the framework remains fit for purpose as household and business energy use shifts away from gas, with feedback open until the end of April.
International policy and investment trends continue to mirror Australia’s focus on storage and distributed energy. In New Zealand, the Electricity Authority has mandated that networks pay households for peak solar exports, a reform designed to accelerate DER uptake and improve grid stability. Meanwhile, investment in large-scale storage is accelerating globally. Neoen unveiled plans for a 300 MW / 600 MWh battery to support the Paris grid, and a consortium of Japanese firms led by Tokyu Land is investing US$190 million into 174 MW of battery projects across Japan.
Today’s developments paint a picture of a two-speed transition. Market prices are reflecting immediate geopolitical anxieties and fossil fuel exposure. At the same time, the physical and regulatory infrastructure for a renewables-dominated grid is steadily being built. The key challenge remains navigating the volatility of the former while accelerating the latter. Submissions on the AEMC's proposed data centre standards close on 7 May.
