We are adding more renewables into our energy mix, recently signing a new solar offtake agreement.

We’ll be buying surplus solar power from the University of Queensland’s Warwick Solar Farm to pass on to our Queensland government customers.

This gives our customers greater choice – we can provide them with tailored solutions, supplying green products and supporting them with energy from our thermal generation assets. This ensures they have lower carbon, reliable, and competitively-priced power.

With more than 200,000 solar panels, the university’s solar farm generates about 160,000 megawatts of clean energy every year – this equates to powering more than 25,000 households.

It allows the university to offset its own energy use, making it the first major university in the world to switch to 100 per cent renewables produced from their own assets.  UQ sells the surplus energy into the market – a portion of which will now be supplied to CS Energy.

Increasing the diversity of CS Energy’s energy products with more renewables supports the Queensland government’s target of 50 per cent renewable energy by 2030.

We are excited to have signed a long-term contract with the Columboola Solar Farm in Queensland to add more renewables to our energy portfolio, drive forward energy investment in Queensland, and power the equivalent of 100,000 homes. 

The 162-megawatt Columboola Solar Farm will deliver power to CS Energy’s large commercial and industrial customers, including major employers such as Griffith University, CQUniversity and QUT.

Columboola will draw on numerous innovations to ensure efficient land use, such as bifacial panels that absorb light from both the front and back and single-axis trackers that follow the sun throughout the day.

CS Energy is focused on investing for Queensland’s future and has recently invested in offtakes for several renewable energy projects across the state as we look to build a stable and sustainable energy grid for the future. While established power plants will have an important role to play for years to come, we’re excited about the role we’re playing to help transition Queensland’s power grid to at least 50 per cent renewable energy by 2030. 

Our contract with the Columboola Solar Farm is just one piece of the puzzle to guarantee affordable and reliable power to Queenslanders, and we’re incredibly proud to be supporting this great project.

As a 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.

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 energy market?

Fast facts about the energy market

• There are more than 200 registered participants in the National Electricity Market (NEM), including market generators, transmission network service providers, distribution network service providers, and market customers.
• The NEM started operating as a wholesale spot market for electricity in December 1998.
• The NEM consists of about 40,000km of transmission lines and cables and supplies about 200 terawatt-hours of electricity to businesses and households each year.
• The NEM supplies about 10 million customers.
• The NEM has a total electricity generating capacity of 55,269 MW (as at April 2020).
• The NEM has about 9,980 MW of distributed solar (as of May 2020).

The National Electricity Market is a 5,000 km-long power system for five Australian regions – Queensland, New South Wales (including the Australian Capital Territory), South Australia, Victoria and Tasmania. It is one of the world’s longest interconnected power systems.

It carries power from electricity generators, like Callide and Kogan Creek power stations, to large industrial energy users and local electricity distributors.

The National Electricity Market is one of the most highly regulated and competitive markets in the world. Electricity prices are set every five minutes – there is no more competitive market than that.

Queensland has had the lowest average wholesale electricity prices in the National Electricity Market for the past three years.

The Australian Energy Market Operator (AEMO) manages the market, helping to ensure that Australians have access to reliable, secure and affordable electricity.

How does it work?

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.

All electricity sales are made through the NEM. Because it is a wholesale market, prices fluctuate in response to supply and demand.

Who or what makes up Queensland’s electricity supply?

There are 4 different stages from generating electricity to delivering it to people’s homes and businesses.

1. Generation– Power stations generate electricity using a range of fuel sources and are both government-owned and private companies.
2. Transmission– Before it can be fed into the electricity network, electricity needs to be increased in voltage to reduce losses. It is then transported via the transmission network to distribution networks.
3. Distribution– Once it reaches the distribution network, electricity voltage is reduced before it is supplied to homes.
4. Retail– Retailers buy electricity on the wholesale market and sell it to customers.
