Comparison of the electricity tariffs and bills across the zones of Australian power distribution companies

This paper first presents a detailed review and comparison of all power distribution companies of Australia in terms of the percentage of the supplied customers and the customer density per kilometer length of their power lines. Following that, the daily electricity supply and the electricity unit charges offered by the active electricity retail companies in the zones of each of these power distribution companies are reviewed and compared. Based on this information, the annual electricity bill of a customer supplied by different power distribution companies and retailers is calculated. Through this study, the national average annual electricity bill is defined for Australia and the power distribution companies are categorized under four segments of very cheap, cheap, expensive, and very expensive companies.
