Cbus Super’s new renewable investment aims to deliver sustainable returns for members and help power Australia’s energy transition
12 August 2025
MEDIA RELEASE
Cbus Super will take an equity stake in Atmos Renewables (Atmos), one of Australia’s leading renewable energy generators as we deliver sustainable returns for members while supporting Australia’s energy transition.
This partnership with existing Cbus investment manager Igneo Infrastructure Partners gives our members greater exposure to a diverse range of renewable energy assets and will support key new developments.
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 (NEM) and Wholesale Electricity Market (WEM), with projects in Queensland, New South Wales, Victoria, Tasmania, South Australia, and Western Australia.
Igneo Infrastructure Partners will maintain decision making control of Atmos, which it established in 2020 to invest in renewable projects at different lifecycle stages.
Cbus’ direct investment – along with capital from other investors – supports two landmark renewable energy developments:
- The 100MW/400MWh Merredin Battery Energy Storage System (MBESS) in Western Australia, Atmos’ first greenfield development and battery project to reach financial close. This $220 million project is expected to create 70 jobs during construction. It will enhance regional grid stability and energy security, with operations expected to begin by mid-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.
Cbus Chief Investment Officer Leigh Gavin said the Fund was excited to partner with Igneo in Atmos – who is an Australian leader in renewable energy generation.
“Atmos’ geographic diversity, long-term contracts and potential development pipeline make it a highly attractive investment,” Mr Gavin said.
“First and foremost, we believe this investment will stack up on returns, but also has the additional benefit of supporting a sustainable energy future for Australians.”
“Atmos’ leadership in wind, solar, and now energy storage, under Igneo's management, makes them ideal partners as we continue our commitment to renewable energy and support for Australia’s energy transition.”
“As well as providing long-term investment returns, the investment supports Australia’s renewable energy industry, a sector that employs many Cbus members. And importantly our portfolio gains more exposure to Australia’s energy transition via a diverse range of renewable energy assets.”
Cbus has over $2.1 billion invested in renewables and enabling infrastructure reinforcing its commitment to the energy transition*.
