Queensland Energy Class Action

CS Energy has begun our defence of a class action lodged by a law firm and funded by corporate backers, which relates to electricity prices. We reject the claims being made and will strongly defend this class action.

CS Energy is committed to complying with all market rules and regulations and we have dedicated substantial resources to ensuring we meet our obligations. Our bidding activity is regulated under the National Electricity Law and the National Electricity Rules by the Australian Energy Regulator.

The Queensland electricity market and customers

As a residential or small business customer, you buy your electricity through a retailer. Your retailer, the company that sends you your electricity bills, manages your energy purchases from the market, and pays the Australian Energy Market Operator (AEMO).

What you pay your retailer includes the costs of generating and supplying you with electricity and can include:

  • network costs -– building and maintaining all the equipment and infrastructure needed to distribute electricity, such as poles, wires, and meter readers.
  • wholesale costs – this is what your retailer pays for your wholesale electricity
  • environmental/green schemes – contributions to compulsory state and federal government environmental/renewable schemes
  • retail services – what you pay your retailer for their services, such as customer service and metering services.

What role does CS Energy play in the electricity supply chain?

CS Energy provides electricity to some of our state’s largest industries and employers. We operate in the generation and retail sections of the electricity supply chain.

We generate electricity at the power stations that we own and operate and we sell this electricity in the wholesale National Electricity Market. We are also a electricity retailer for large energy users throughout Queensland, such as mines, ports and government.

In South East Queensland we have a retail joint venture (JV) with Alinta Energy to supply electricity to residential and small commercial customers. Since entering the SEQ retail market in 2017, the JV has been recognised for helping to stimulate competition, leading to better price outcomes for consumers regardless of their retailer.

How it works

Generators offer to supply the market with an amount of electricity at a certain price for a specific time period. They can re-submit the amount at any time.

AEMO considers the offers and decides which generators will be used to produce electricity, with the cheapest generator put into operation first. This process is designed to meet everyone’s electricity demands in the most cost-efficient way.

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.
