Australia's largest energy transmission project, EnergyConnect, has reached a major milestone with the completion of over 1500 steel towers across NSW, Victoria, and South Australia. Despite delays and cost blowouts, the project aims to connect the power grids of three states, supporting Australia's renewable energy and emissions targets. Workers are assembling and erecting towers weighing between 20,000kg to 60,000kg, suspended 65m off the ground. Scheduled for completion by late 2026, EnergyConnect will accelerate Australia's renewable energy transition and strengthen the national grid.

Neoen begins construction of another big battery, first in world to deploy Tesla Megablock technology
Neoen Australia has commenced construction on the Goyder battery project in South Australia, utilizing Tesla's new Megablock product to create a 226 MW, 866 MWh battery that will power BHP's Olympic Dam mining operations. This project is part of Neoen's efforts to lead in battery storage projects in Australia and contribute to the energy transition by lowering costs for grid-level storage by up to 40%. With planning approval for up to 900 MW of capacity and 3,600 MWh, the Goyder battery could potentially become part of Australia's largest hybrid project, integrating large scale solar and expanded wind farms. Neoen's projects, including the Goyder battery, are crucial in South Australia's aim to achieve 100% "net" renewables by 2027.

Offshore wind turbines create all-you-can-eat havens where some fish can double in size
A new study found that offshore wind farms can lead to larger fish species and increased complexity in the oceanic food chain due to the rough surfaces of turbine monopiles and submarine cables providing new habitats for marine organisms. The presence of wind turbines created a different marine environment with positive attributes, such as increased biomass of benthic fish and sessile organisms colonizing the structures. Additionally, the wind farm acted as a no-take zone, serving as a marine protected area for commercially targeted species and contributing to a more stable, diverse, and functionally intact ocean life compared to areas without turbines. While there are risks associated with exploration and construction, the study suggests that wind farms can have positive impacts on marine ecosystems by providing new habitats and increasing food availability for marine life.

First solar-battery hybrid on Australia’s main grid is energised, and ready to send PV into evening peaks
The first large scale solar-battery hybrid power plant on Australia's main grid, Quorn Park, has been energised and is ready to send solar power into evening demand peaks. This facility combines an 80 MW solar farm with a 20 MW, 40 MWh battery, allowing for solar to be stored and fed into the grid during peak demand times. Solar-battery hybrids are seen as a solution to provide reliable and cost-effective support to the grid, meeting the evolving needs of communities and accelerating the energy transition. Solar battery hybrids are becoming increasingly popular in the green energy transition, with Chris Bowen naming 20 winners of a 6.5 gigawatt CIS tender, making them a key technology for clean energy solutions.

Rooftop solar and batteries on centre stage: Six key graphs from AEMO’s transition roadmap
The Australian Energy Market Operator has released the draft of its 2026 Integrated System Plan, outlining the transition of Australia's main grid to renewables and storage. The plan highlights the growth of rooftop solar and the potential for an accelerated transition to green energy, with a focus on addressing transmission concerns and the continuation of coal in Queensland. AEMO is unsure how to keep coal running until 2049 due to aging coal-fired power stations being a threat to grid reliability, but the concept of "baseload" is expected to be phased out. The grid is projected to reach 82% renewables by 2030, leading to a significant drop in emissions and paving the way for further emission cuts in other sectors as they electrify and transition to renewables.

Offshore wind farms could be used as charging hubs for electric and hybrid ships
Two Danish companies are exploring the integration of offshore wind with marine electrification to reduce vessel-related greenhouse gas emissions. Stillstrom, a leader in marine technology, aims to provide offshore power and charging solutions for battery powered vessels. A joint white paper with the Port of Roenne on the Danish island of Bornholm will explore how offshore wind can support charging solutions for electric ferries and cargo vessels. Bornholm, designated as an energy island, is central to one of the busiest shipping corridors in Europe and plans to build offshore wind farms to support maritime electrification. The concept of "energy islands" as hubs for offshore power transmission is discussed, with estimates of 17 terawatt-hours of electricity needed for battery-powered vessels. This transition could save €2 billion in oil imports and reduce marine gas oil emissions. The Port of Roenne sees itself as well-positioned to contribute to the infrastructure needed for maritime electrification, including ferry and cruise vessel charging. Energy Island Bornholm is seen as a valuable opportunity to understand future maritime energy needs and support the wider transition to clean energy in Europe's shipping corridors.
