About the project
With a capacity of 399 MW, the Tamar Valley Power Station is the second largest power station in Tasmania. The station, which is owned by distribution company, Aurora Energy, comprises three existing gas turbines, a new 60 MW open cycle unit and a new 210 MW combined cycle gas turbine. The new plant is connected to the power system at our George Town Substation via separate 110 kV and 220 kV circuits
Connecting the new power station to the grid required upgrading the existing 110 kV connection and constructing a new 220 kV transmission line to connect to the largest generating unit. As well as providing metering and communication facilities, we also installed and commissioned a generator contingency scheme to help the Tamar Valley Power Station comply with Tasmania’s new frequency operating standards.
The benefits
Tasmania now has access to another major source of power generation and new frequency operating standards have been put in place.
Completion date
The project was completed in 2009.
