AEMO data shows 1,504 MW of new battery capacity entered the NEM in Q1 2026, pushing total annual additions to a record 4,445 MW and driving coal and gas generation to new lows. This storage surge helped renewables reach a 46.4% market share and generated $96.9 million in quarterly revenue for battery operators. The influx of storage is actively reshaping market dynamics, though it coincided with a 22.1% week-on-week jump in NEM average spot prices to $65.25/MWh, reflecting ongoing volatility.
While batteries are reshaping the market, policy is pulling in multiple directions. The New South Wales Labor government has overturned its long-standing ban on fossil gas exploration, opening the state to new extraction for the first time in over a decade. The government framed the policy reversal as a necessary step to secure energy reliability during periods of low renewable output, signalling a more cautious approach to the transition away from retiring coal generators.
Consumers will soon feel the cost of grid upgrades. The Australian Energy Regulator set new network tariffs that will increase default market offers from the 2026-27 financial year across the NEM, excluding Victoria. The decision underscores the growing pressure on transmission planners to keep pace with new generation. In Victoria, the offshore wind industry is urging VicGrid to expedite its plans for Gippsland to connect the first 2 GW of capacity expected by 2029. Meanwhile, the 252 MW second stage of Queensland's Wambo wind farm has officially entered AEMO's grid management system.
State governments are also intervening directly to fund the buildout. Western Australia’s new $1.4 billion fund will finance the Clean Energy Link and expand the Southwest Interconnected System, accelerating the state’s grid transformation. The investment case for storage is strengthening globally, with S&P Global Energy analysis finding that recent lithium price surges have had only a minimal influence on total BESS costs. This divergence from historical trends is helping sustain project momentum. The technical case was further demonstrated at Bellevue Gold’s off-grid WA mine, which achieved a record 93.8% renewable energy share over a full month.
Despite the record pipeline of projects, warnings on future reliability persist. New Zealand’s grid operator Transpower warns the country faces an energy security gap by 2031 without further firming investment, a cautionary note for NEM planners managing a similar transition. Closer to home, regulators are focused on refining market frameworks for the new technology mix. The AER is seeking feedback on its draft guideline for the SA FERM scheme, with submissions due by 19 May.
