Gas network tariffs will increase by 7.8 per cent each year for the next five years, largely due to the economic environment, under a decision published today by the Economic Regulation Authority for Australia’s largest gas distribution network.
The ERA has published its final decision on the access arrangement for ATCO’s Mid-West and South-West Gas Distribution Systems, which delivers gas to more than 800,000 households and businesses across Kalgoorlie, Geraldton and the South-West.
ATCO’s network charges make up around 30 per cent of the average household gas bill and are determined through the access arrangement review process every five years.
The forecast increase in the gas network bill for the average residential customer on 1 January 2025 is 7 per cent (in addition to inflation).
The Western Australian Government sets the maximum price that small use customers (residential and small businesses) can be charged.
Gas retailers will decide if and when they pass on these network tariff increases to customers that are on competitive or discounted contracts.
