Apart from connecting large generators to end-use customers through the distribution networks owned by Energex and Ergon Energy (part of the Energy Queensland Group) and Essential Energy (in northern New South Wales), we also directly provide electricity to large industrial customers such as rail companies, mines and mineral processing facilities.
