What we deliver

Hornsdale Wind Farm

Renewables series – Part 3

We’re committed to supporting Australia’s transition to a low-carbon economy through targeted investments in renewable energy infrastructure.

In April 2025, we completed the sale of our stake in Bright Energy Investments (BEI). This decision reflects our approach to actively manage our portfolio and consider opportunities to recycle capital from mature assets into new investments. BEI’s portfolio included 367MW of wind and solar renewable energy projects across Western Australia and delivered strong returns for our members.

In August 2025, we announced our investment in Atmos Renewables (Atmos) through our partnership with Igneo Infrastructure Partners. Atmos has 18 renewable assets in operation and under construction, with a combined capacity of 1.5GW – enough to power about 775,000 homes or a city larger than Adelaide. Its projects span the National Electricity Market and the Wholesale Electricity Market, with projects in Queensland, New South Wales, Victoria, Tasmania, South Australia, and Western Australia.

Atmos is focused on renewable projects across various stages of the investment lifecycle and supporting Australia’s future energy needs, whilst delivering reliable, long-term returns.

Our investment will help to support two landmark assets:

• The 100MW/400MWh Merredin Battery Energy Storage System in Western Australia is Atmos’ first greenfield development and battery project to reach financial close. During construction this $220 million project is expected to create around 60 to70 jobs, including an anticipated 11 apprentices. It will enhance regional grid stability and energy security, with operations expected to begin by 2027.
• The full acquisition of the 316MW Hornsdale Wind Farm in South Australia, increasing Atmos’ stake from 23.4% to 100%, further strengthening its contracted income base.

As at 31 March 2025, we have over $2.1 billion invested in renewables and enabling infrastructure, within our infrastructure portfolio. Our aim remains to deliver sustainable returns for members, while supporting Australia’s energy transition.
