About the project
The Hadspen Substation has long played a key role in the electricity transmission system in northern Tasmania, transforming electricity from 220 kV to 110 kV and then to lower voltages at the Trevallyn and Norwood substations. But the substation was not able to supply directly to Aurora’s distribution system, limiting its supply options. The redevelopment work, which involved the installation of new 110 kV and 22 kV switchgear as well as two 110/22 kV transformers and associated protection and control systems, means electricity can now be supplied directly into Aurora’s distribution system. The supervisory control and data acquisition system (SCADA) also was upgraded. The redevelopment work represents and investment of almost $8 million.
The benefits
As a result of the redevelopment, we’re better able to manage the load at substations supplying the greater Launceston area and Aurora has more flexibility in managing supply to its customers in West Launceston, Westbury, Longford and Perth. The upgrade of the SCADA system has improved communications between the substation and our central network operation and control system.
Completion date
The Hadspen redevelopment work was completed in 2006.
