CS Energy is a Queensland Government-owned energy corporation that was established in 1997.
We generate and sell electricity in the National Electricity Market, and we are an energy retailer to large commercial and industrial businesses.
We have operations in Central Queensland, the Western Downs and South East Queensland, and employ more than 730 people.
Our purpose
Deliver safe, reliable, affordable and sustainable energy for Queensland
Our portfolio
CS Energy's portfolio includes coal-fired power stations, renewable energy, firming and storage. In FY2026, we produced 27.3 per cent of electricity generated in Queensland.
In the Western Downs, we own and operate the Kogan Creek Power Station, the Kogan Creek Mine which fuels the power station, and the Chinchilla Battery.
Adjacent to our existing Kogan Creek operations, we are building the gas-fired Brigalow Peaking Power Plant.
In Central Queensland we own the Callide B Power Station and have a 50 per cent interest in the Callide C Power Station where we provide operations and maintenance services to the Callide C Joint Venture.
We trade energy generated by Gladstone Power Station, in excess of the requirements of the Boyne Island aluminium smelter.
CS Energy has a renewable energy portfolio of 900 MW (owned capacity and offtakes), which includes generation either in operation or under construction.
Our role in the energy supply chain
Our customers
Our large commercial and industrial customers include mines, airports, ports and Queensland Government departments and agencies.
Our dedicated Retail Business Team has significant energy market expertise and works directly with our customers to provide bespoke energy solutions, including through firmed renewable supply.
We also have a 50/50 retail joint venture with Alinta Energy that supplies electricity to residential and small commercial customers in South East Queensland. We formed this joint venture in 2017 to introduce greater competition in the SEQ retail electricity market.
In the wholesale market, our customers are large businesses that use financial derivatives to manage their exposure to pool price volatility.
Our communities
CS Energy is proud to call Biloela, Chinchilla, Brisbane and Greenbank home, and we are committed to building lasting and positive relationships in these communities.
We are an organisation with deep roots in regional Queensland, creating employment and economic opportunities that helps to sustain local communities.
We invest in these local communities through our annual sponsorship and donation programs, and by procuring goods and services from local suppliers wherever possible.
