Objectives To determine the leakage rate from our MP mains networks and what relationship can be demonstrated between pressure and leakage. The ambition is to prove the relationship so that networks can consider the transfer of pressure management technology to MP system when this would deliver significant customer environmental benefits. Success of this project will be a comprehensive assessment of a methodology that demonstrates the effect of pressure on MP system leakage and an economical way to assess the current leakage from MP systems. This will be provided in a report with detailed findings and recommendations that can be carried forward for implementation.
Abstract All Gas Distribution Networks have a modeled level of leakage for Medium Pressure (MP - 75mbarg to 2000 mbarg) systems. At present, whilst we know there is a relationship between pressure and leakage from our MP distribution system, the modelling methodology is unable to calculate the pressure effect and show the benefits that reducing the pressure would have on the level of gas losses. Networks would like to identify the level of leakage on our medium pressure system and the relationship that reducing the pressure has on the total volume of leakage, which once known, would allow networks to find solutions to reducing leakage levels and in turn the impact on the environment in reduced emissions. Investigate through a mixture of analytical modelling, research of other EU country methodologies and laboratory testing of analytical models to determine the leakage and pressure relationship for our Medium Pressure asset population. Includes analysis to determine the most economic and efficient statistically robust mechanism for calculating the impact of pressure reduction on leakage.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
