The Design and Impact of Unaccounted for Gas Reduction Policies For Natural Gas Distribution Network In Ireland And The United Kingdom

Unaccounted for gas (UAG) is the challenge faced by the natural gas industry which has financial, environmental as well as safety implications. The regulators have the authority to control the extent of the financial costs that can be passed on to the end-users by the transporters and distributors to recover the cost of UAG. There has been action taken by the regulators in Ireland and the United Kingdom to reduce the amount of UAG, which is beneficial to end-users as well as transporters and distributors. This paper discusses the design of the UAG calculation methodology of the distribution network. It highlights the approach taken by the regulators to reduce UAG along with the observed UAG trends in the distribution network.
