Energy management and climate

Energy management and climate

Sustainably reducing our operational energy expenses help us keep water and sewerage charges as low and stable as possible, and is one way we can contribute to easing cost of living pressures for our customers.

We are one of the state’s single largest electricity users, with our energy-intensive drinking water and wastewater pumping and treatment operations across South Australia costing approximately $86 million in 2019-20.

Our ambitious zero cost energy future project will be delivered through seven key initiatives that include demand scheduling, energy efficiency, energy storage, our own generation, and energy market levers that will position us to effectively manage our long-term energy usage.

Increasing our own generation capacity will deliver the largest leaps on our ambitious path towards a zero cost energy future. We’re investing more than $300 million to generate 242 gigawatt hours of energy per annum by installing 154 megawatts of solar photovoltaics at more than 30 sites and 34 megawatt hours of energy storage devices.

This will be achieved with 360,000 solar panels across more than 30 sites working to harness the power of the sun. To put this into perspective, all these panels laid end-to-end would stretch more than 740 kilometres in length.

Combined, our solar arrays will have the capacity to generate approximately 70 per cent of our electricity needs in an average weather and water consumption year.

How our zero cost energy future will benefit you

The energy we generate and store on-site will reduce our reliance on expensive grid electricity and create a revenue stream, helping to deliver sustainable operational savings for the benefit of our customers.

Our installed renewable generating capacity will be equivalent to the power needs of in excess of 53,000 average South Australian homes.

We aim to set an example of proactive environmental leadership and action towards addressing climate change, and this initiative will help us achieve an emissions reduction of around 340 tonnes per year, which is the equivalent to planting seven million trees, or removing more than 32,000 cars from the road per year, every year of operation.

Importantly, our progressive leap forward will help the global transition to a low-carbon future.
