How is IGS Energy able to procure natural gas if it is not a gas marketer and doesn't own pipelines?

IGS Energy owns firm (uninterrupted) natural gas transportation rights on the Southern Natural and Transco pipelines. This provides shippers with the capacity to move natural gas on a firm basis from primary receipt points to primary delivery points to ensure that the gas gets to market.

IGS Energy also maintains a network of producer and supplier relationships that ensures reliable, competitively priced natural gas supply and capacity. The large aggregate volumes we move on the interstate pipelines allow us to benefit from economies of scale and purchase natural gas at highly competitive prices.
