Pacific Green, a global battery energy storage company, has secured a planning permit from the Victorian Government for its second Australian grid-scale battery energy park located in Portland, Victoria, Australia. The announcement was made on September 22, 2025, from Sydney.

Project Scale and Development Timeline

The Portland Energy Park will provide up to 1 GW of firming capacity of energy storage. The project will be developed in phases over the next 36 months. Once constructed, it will become Australia's largest battery energy park. The energy park is located in regional Victoria, in one of the State's core industrial hubs. Once operational, the facility will enable the avoidance of 66,900 tonnes of carbon dioxide each year.

Strategic Location and Industrial Integration

The Portland Energy Park is strategically positioned within the industrial-zoned area on Madeira Packet Road. The facility is situated in proximity to the Portland Aluminium Smelter and the Portland Water Treatment Plant, enabling the asset to provide energy security to strategic businesses and augment the existing electrical infrastructure located nearby. The project's location in regional Victoria will significantly boost energy storage capacity, enhance Victoria's energy stability, and support the state's transition to net-zero emissions.

Planning and Community Engagement Process

Pacific Green undertook a comprehensive program of technical, environmental, and operational assessments to support the planning and approvals process, ensuring the project minimizes potential impacts and fully complies with, or exceeds, all statutory requirements. The company complemented this with an extensive program of community and stakeholder engagement, including consultation with local First Peoples representatives, whose cultural heritage insights played a key role in shaping the final design of the energy park.

Government and Company Leadership Response

Hon. Sonya Kilkenny, Minister for Planning, commented that “Our fast-tracked pathway has unlocked more than USD 6 billion worth of investment into renewable energy projects – helping provide cheaper and cleaner energy to hundreds of thousands of Victorian households.” Hon. Lily D'Ambrosio, Minister for Energy and Resources, stated: “This battery will soak up cheap renewable power during the day and deliver it when demand peaks, powering 345,000 homes and slashing energy bills across the state.”

Scott Poulter, Chairman and Group CEO of Pacific Green, commented: “We are pleased that our second Australian asset has secured the support needed to move forward. Drawing on our global expertise in developing energy parks across the UK, Europe, and Australia, the Portland project will play a major role in decarbonizing Australia's energy system. Its scale underlines our ambition to become a leading developer in the market and to accelerate the nation's transition to renewables through a multi-gigawatt platform.”

Joel Alexander, Managing Director of Pacific Green Energy Storage Australia, stated: “We are thrilled to reach today's milestone as it represents a significant achievement for Pacific Green. Once operational, Portland will stand as Australia's largest grid-scale battery, driving Victoria's energy transition forward. At a regional level, we extend our thanks to local First Nations representatives, the community, and stakeholders for their engagement, and we look forward to sharing further updates on supply chain opportunities as the project progresses.”

Company's Broader Australian Operations

The Portland Energy Park represents the next step in Pacific Green's ambition to develop its pipeline of over 7 gigawatt-hours (GWh) of battery energy storage across the National Electricity Market. This follows the successful development of 1 GW of battery energy storage at the Limestone Coast, South Australia.
