Throughput
When first constructed, the capacity of the system was 360 TJ/day. A $150m enhancement carried out in 1991 increased the capacity to 450 TJ/day. The current capacity of the pipeline is approximately 785 TJ/day. The pipeline is currently undergoing a series of significant expansions in its capacity which are intended to increase the maximum throughput of the pipeline to 895 TJ/day. The expansion project consists of two types of upgrade. Several of the pipeline's compressor stations will be upgraded with higher capacity gas turbines, thus increasing the actual pressure of the gas inside the line. In addition, the expansion involves a process of 'looping' the pipeline. This is the installation of additional lengths of pipe alongside, and connected to, the existing pipeline. The effect of looping is to provide additional capacity at critical sections of the main trunkline, thus increasing the total possible throughput.
