ACT Government Approves Williamsdale Battery Energy Storage System
The ACT government has reached another milestone in its effort to future proof Canberra’s energy supply by submitting the development application for a big grid connected battery. The 250 MW/ 500 MWh Williamsdale Battery Energy Storage System will store renewable energy and support network reliability. The ACT will also install three medium sized neighbourhood-scale batteries in the suburbs of Casey, Dickson and Fadden thanks to a $1.5 million Federal Government grant. What is a battery? A battery accepts chemical energy and converts it to electricity by an electrochemical oxidation-reduction (redox) reaction. Batteries power many electronic devices, from remote controls to car engines. Inside a cylinder-shaped battery are one or more electrochemical cells. Each cell has two electrical terminals — a positive end (cathode) and a negative end (anode) — separated by a chemical material called an electrolyte. When the negative and positive ends are connected by a wire, electrons flow...
