The Clean Energy Investor Group has warned draft federal environmental reforms are 'scientifically tenuous' and risk derailing Australia's wind project pipeline. The group argues the proposed EPBC Act conditions are overly conservative, threatening the financial viability of new developments with disproportionate constraints. This policy friction echoes broader industry complaints, with wind developers reporting that escalating planning delays are inflating capital costs and project complexity. The development hurdles come as NEM spot prices jumped 18.5 per cent week-on-week to average $88.05/MWh, underscoring the market's urgent need for new generation capacity.
While wind developers grapple with policy uncertainty, the energy storage sector is hitting significant milestones. In South Australia, AGL Energy completed installation of its 250 MW / 1,000 MWh Torrens Island battery, installing the last of 1,038 Wärtsilä Quantum units. The four-hour duration asset will provide critical firming capacity. Also in South Australia, Lunio Energy commenced NEM trading with its 20 MWh utility-scale battery in Strathalbyn, its first operational grid-connected asset. The project pipeline continues to build, with Danish developer European Energy reaching financial close on its 80 MWh Mokoan solar-plus-storage project in Victoria. Spanish developer FRV also secured finance to begin construction on the 200 MW Glenellen Solar Farm in New South Wales.
This influx of storage and hybrid capacity arrives as stakeholders grapple with the grid impact of new, energy-intensive industries. Warnings are emerging to apply lessons from past resource booms to manage the rapid expansion of data centres, avoiding the boom-and-bust cycles that plagued mining and hydrogen. The caution highlights a need for strategic oversight, reinforcing the federal government's recent focus on ensuring new large loads contribute to their own supply. The state government is also seeking firming solutions, now evaluating proposals for a 10-hour vanadium flow battery to support the grid around a historic gold mining centre.
As the Australian market matures, so too must its commercial strategies. A new Gridmatic report from California's CAISO market warns that battery operators are losing millions by using static 'set and forget' bidding strategies. The analysis found that dynamic, AI-driven dispatch captures peak volatility far more effectively than fixed participation models. This matters for Australian BESS operators navigating an increasingly complex market. Meanwhile, international policy is also evolving to secure dispatchable capacity. Germany has launched its first 4.5 GW auction for firm generation and long-duration storage, while India just awarded contracts for 1,344 MW of pumped hydro and its first utility-scale flow battery.
Looking ahead, the detailed work of market reform continues. AEMO has begun planning for its 2026 Transmission Plan for System Security, incorporating feedback from the 2025 process. The market operator has also opened several new consultations. These include discussion papers on the network access quantity model and procedures for participant registration, with submissions due in mid-August.
