About the project
The Que Substation in north-west Tasmania was constructed in 1980 to supply electricity to a mining company. Que Substation is the sole source of electricity to the mine and any transformer failure will impact on mining operations. The upgrade saw the replacement of an ageing transformer in poor condition with an existing spare transformer. As part of the work, a compliant oil containment system was installed and protection and controls systems were modified to suit the new transformer.
The Ulverstone Substation has been supply electricity to customers in Ulverstone and the surrounding area since 1978 and connects to the Emu Bay Substation and to the Paloona Tee Switching Station. The upgrade work involved replacing a 110 kV circuit breaker and associated protection and control equipment. The upgrades required an investment of more than $2.5 million.
The benefits
The work addressed two areas of weakness in the transmission system, helping us to provide a more reliable and secure transmission service to our customers in this important region. It has helped to avert a potential failure affecting a mining operator.
Completion date
The upgrade projects were completed by the end of 2008.
