In the heart of Queensland's generation region
Some of Queensland's major generators are a short drive from Dalby, including Kogan Creek at Brigalow, the Braemar gas power stations near Kogan, Condamine Power Station near Miles and Millmerran Power Station. That puts WJC within easy reach for outages and urgent work.
