We operate careful water management strategies across all of our sites to ensure the most efficient use of this precious resource, which is a vital part of the electricity generation process.

As a result, we use a combination of raw water and town water across our sites and each site has a water management strategy in place.

Dry cooling technology

The advanced design of the Kogan Creek Power Station uses fans rather than water to condense boiler steam back into water for reuse. This process, known as ‘dry cooling’, results in 90 per cent less water use compared to an equivalent wet-cooled power station.

The limited amount of water the station does use is sourced from local bores.

Pumped storage hydro

As a pumped hydro power station, Wivenhoe Power Station is highly water efficient as it recycles water between an upper and lower reservoir (Splityard Creek Dam and Lake Wivenhoe) to generate electricity.  

Other water use

At Callide Power Station, the majority of our site water is sourced from the Gladstone Area Water Board's Awoonga Dam and is piped to Callide Dam. Around 85 per cent of the water used at Callide Power Station is evaporated in the cooling towers. The remainder is recycled and used for dust suppression, ash transport and other process water, and finally evaporated in on-site ponds.  The power station's environmental and chemistry teams carefully monitor water use and quality, and is evaluating water conservation activities.
