Columbia Gas Transmission Storage


With more than 30 storage locations in four states, Columbia Gas Transmission Storage has enough capacity to handle almost 630 billion cubic feet (Bcf) of natural gas. That’s enough to ensure that the hundreds of communities along the Columbia Pipeline route don’t run out of the natural gas they rely on every day—even when the temperature dips and usage rises.
