CS Energy\

Wholesale market

CS Energy has more than 20 years of experience selling energy in the National Electricity Market (NEM). We manage plant and financial risk by balancing our presence in the wholesale spot and contract markets.

We operate in strict accordance with, and take very seriously, our obligations to comply with all rules and regulations governing our participation and bidding in the NEM.

Our trading portfolio

CS Energy has a trading portfolio of 3,535 megawatts from power stations we own and operate and trading rights for the Gladstone Power Station (in excess of what we supply to the Boyne Island aluminium smelter). We also have renewable energy offtakes to support our customers' requirements for a mix of thermal and renewable generation. 

Our role in the NEM

The NEM is a wholesale electricity market in which electricity supply and demand is matched instantaneously in real time. 

In the spot market, CS Energy sells electricity and retailers buy it to on-sell to consumers. Prices fluctuate in response to supply and demand at any point in time. It’s a dynamic, highly competitive market with more than 100 generators and retailers.

To manage exposure to price volatility in the spot market, generators and retailers often use financial derivatives to manage lock in a firm price for electricity at a given time in the future.

In the contract market, CS Energy also provides tailored energy solutions to large commercial and industrial users such as state government departments and agencies.

Ancillary services

CS Energy provides a range of ancillary services to help maintain the power system within the NEM’s performance standards. These services underpin the security and reliability of electricity supply for Australians.
