Natural Gas Pipelines & Services
Our Natural Gas Pipelines & Services segment consists of the Acadian Gas System, which is an onshore natural gas pipeline system that
gathers, transports, stores and markets natural gas in Louisiana. The Acadian Gas System links natural gas supplies from onshore and
offshore Gulf of Mexico developments (including offshore pipelines, continental shelf and deepwater production) with local gas distribution
companies, electric generation plants and industrial customers, including those in the Baton Rouge-New Orleans-Mississippi River corridor.
In the aggregate, the Acadian Gas System includes over 1,000 miles of high-pressure transmission lines and lateral and gathering lines
with an aggregate throughput capacity of approximately 1.0 Bcf/d and 3.0 Bcf of storage capacity.
The Acadian Gas System has over 150 physical end-user market direct connections. In addition, the system interconnects with 12 interstate
and 4 intrastate pipelines through 50 separate interconnections, has a bi-directional interconnect with the largest U.S. natural gas
marketplace at the Henry Hub, and is directly connected to six merchant and utility electric generation facilities with over 6,000 megawatts
of generating capacity. The numerous interconnections allow the Acadian Gas System to leverage basis differentials across the South
Louisiana pipeline network, maintain a diversified supply portfolio and create capacity and transportation opportunities for its shippers.
The Acadian Gas System's bi-directional interconnect with the Henry Hub provides physical and financial pricing flexibility, in addition to
facilitating access to the many buyers and sellers of natural gas at the hub.
