Abstract: This paper describes the methodology for balance improvement in the natural gas transmission network at TGI (Transportadora de Gas Internacional). The approach is based on the application of uncertainty analysis on two levels. A first micro-scale level, defined by the uncertainty budget of the flow measurement systems, and a second macro-scale level, related to the uncertainty associated with the result of the balance for the entire network. A cyclic process is applied to simulate the effects of the different improvement actions both on the original flow measurement systems uncertainty and the balance uncertainty. The process ends when a given improvement action do not show a significant change in the uncertainty associated. With the application of this methodology has been possible to program an optimal investments plan, oriented to obtain better balances in a short-term.
