Australian household electricity costs could rise by 26 per cent if data centre expansion relies on gas generation, a new study warns. This potential long-term price shock contrasts sharply with current market conditions, as NEM spot prices plummeted 45.7 per cent week-on-week to average $48.01/MWh. Mild weather and strong renewable output drove the decline. The study urges immediate regulatory intervention on power and water consumption by AI facilities to prevent shifting infrastructure costs onto residential consumers.
Regulators are already grappling with managing new sources of electricity demand. A Victorian parliamentary inquiry is tackling the challenge from electric vehicles, issuing 40 recommendations to improve EV integration, including introducing contestable network connections. The committee wants distributors to share granular capacity data to foster competition and prevent them from monopolising the charging infrastructure market. In New South Wales, the focus remains on supply, with calls for the new Investment Delivery Authority to be resourced to accelerate critical renewable project approvals amid investor frustration over persistent bottlenecks.
At the household level, major policy shifts are underway to manage demand. From 1 July, large retailers must offer the Solar Sharer scheme in NSW, south-east Queensland, and South Australia. The programme grants households 24kWh of free electricity during midday solar troughs to ease grid pressure. However, Energy Consumers Australia cautions that some participants could face higher overall costs depending on their specific usage patterns. Meanwhile, the Clean Energy Regulator reports that revisions to the Cheaper Home Batteries rebate have moderated record demand, though installation volumes for household systems remain historically high.
While policy debates continue, significant storage assets are coming online. Akaysha Energy’s 415MW/1,660MWh Orana BESS has reached full operational output in New South Wales, adding substantial capacity and flexibility to the NEM. This milestone is matched by investment signals from other states. The Queensland Investment Corporation has opened a formal call for proposals under the state's AU$200 million North West Energy Fund. The fund targets new battery storage and generation projects to bolster regional energy supply and security.
The consumer-led transition continues to accelerate, further reshaping demand patterns. Electric vehicle sales hit a record 20 per cent market share in May, with models from Tesla, BYD, and Geely surging as diesel ute sales slumped. This rapid uptake underscores the urgency of the grid integration work being debated in Victoria. Globally, other jurisdictions are deploying similar tools to manage their own transitions. The European Commission just approved Spain's €9 billion capacity market, a mechanism designed to secure long-term reliability using storage, demand response, and conventional generation assets.
The regulatory pipeline is busy addressing these challenges. The Australian Energy Regulator is consulting on Essential Energy’s application for a ring-fencing waiver to provide kerbside EV charging, with submissions closing on 14 July. Meanwhile, AEMO is seeking feedback on its draft 2026 General Power System Risk Review and a discussion paper on System Restart Ancillary Services. Submissions for both close later this month, shaping the rules that will govern Australia's evolving grid.
