What it means: Volume of natural gas that may be carried on a pipeline over a period of time. All gas volumes delivered.
See it in action: Natural gas pipelines operate within a range of pressures in order to send more or less gas to consumers based on demand. Meaning the total throughput on a pipeline in a given day, week, or month may vary widely, depending on if customers are turning up their furnaces or lounging in the sun.
If it’s cold outside gas demand is typically higher, meaning more gas will be packed into the pipeline at the producer end to be brought to market, thus increasing throughput.
Gas use in the Northwest peaks during the winter months, so that’s when you can expect to see the highest throughputs on pipelines serving our region.
