New Substation To Serve Eastern Travis County

Austin Energy crews and contractors have been busily at work constructing the new Dunlap substation in far eastern Travis County to get portions ready for this summer.

The substation is being built in phases over the next two years to serve growth and help relieve transmission congestion on the statewide grid. The substation will serve both transmission and distribution needs and will include the largest autotransformer ever for Austin Energy at 672 megawatts (MW), 30 feet tall and weighing almost 500 tons. An autotransformer steps-down high voltage coming in from power plants. By contrast, the second largest autotransformer in the Austin Energy system is 480 MW.

The substation also will include a 30 MW transformer to support distribution of power to Austin neighborhoods.
