The Victorian government granted planning approval for four projects totalling 1,390 MW of battery capacity, fast-tracking AU$2.4 billion of investment to bolster grid stability. The move provides a critical boost to storage deployment amid a challenging market. NEM spot prices jumped 23.9 per cent week-on-week to average $67.25/MWh, underscoring the system's need for flexible capacity. Despite policy tailwinds like the federal Capacity Investment Scheme, wind farm developers report deteriorating project economics, citing escalating construction costs and volatile offtake markets as major barriers to final investment decisions.
This state-level support for renewables contrasts sharply with policy shifts in Queensland. There, the Planning Minister gained new authority to fast-track petroleum developments and override existing regulatory bodies. The move follows the same minister's recent interventions to halt several renewable energy and battery projects, creating a stark policy divergence between the NEM's major states and signalling a complex, fragmented path for the national energy transition.
Still, major industrial energy users are driving progress. Lightsource bp has started construction on a large-scale solar and battery facility to directly supply a major smelter, a project the developer calls a milestone for decarbonising heavy industry. In the data centre sector, Drax Energy Solutions signed a 10-year PPA with Global Switch to supply 30 per cent of the operator's electricity needs. Drax is also pursuing a $755 million acquisition of Bluefield Solar to expand its generation portfolio, highlighting how corporate demand is creating bankable offtake agreements.
On the operational front, Akaysha Energy restored its 700 MW / 1,680 MWh Waratah Super Battery to full capacity after reinstating its second high-voltage transformer. The return of Australia's most powerful battery to its maximum operating scale is a key development for NSW grid services. The event comes as the industry deepens its focus on BESS safety, with new analysis examining modelling techniques to prevent thermal runaway risk in lithium-ion systems. Looking ahead, Tesla Energy's regional director flagged the company's focus on integrating large and small batteries and introducing vehicle-to-grid technology to manage solar exports.
Regulators are also adapting to the changing market. The Australian Energy Regulator is consulting on new draft retail guidelines aimed at creating a more “honest and fair” consumer experience through improved billing transparency. This domestic focus on consumer outcomes is mirrored by challenges emerging in mature renewables markets overseas. The Dutch market regulator will allow operators to deprioritise household solar from 1 July, a measure to ease distribution grid constraints that offers a glimpse into future network management challenges for Australia.
Submissions on AEMO’s discussion paper for shortening the NEM settlement cycle are due by 18 June. Meanwhile, the AER is seeking feedback on its draft retail guidelines until 17 July, signalling ongoing regulatory reform across both wholesale and retail markets.
