Project Background AGL Resources has built a natural gas storage project in the Spindletop salt dome, hollowing out the salt approximately a half-mile to a mile below ground to create caverns. Virtually impermeable and protected deep underground, salt dome caverns are the safest means of storing natural gas.

Stored natural gas provides a number of benefits:
  • balances changes in the consumption of natural gas;
  • stabilizes prices; and
  • provides a buffer against disruptions.
The Golden Triangle Storage project increases Jefferson County's natural gas storage capacity significantly, enhancing the area's position as a national energy hub and increasing the functionality of both its existing and planned energy infrastructure.

Golden Triangle Storage was built and is operated to meet or exceed the latest safety and environmental regulatory guidelines. Located on land to the south of Beaumont, the facility is on the site of old sulfur mines, continuing oil production, and near existing storage facilities.

Market Need
Golden Triangle Storage is conveniently located near natural gas supplies, including natural gas imported through area liquefied natural gas (LNG) terminals, East and South Texas natural gas fields and offshore wells. A number of nearby pipelines can deliver this natural gas to customers in the region as well as to markets in the Northeast, Mid-Atlantic and Southeast.

Golden Triangle Storage will initially offer 12 billion cubic feet (Bcf) of working gas capacity – enough natural gas to power nearly 300,000 Texas homes for a year – in two salt dome caverns and can be expanded to 28 Bcf. It will offer both firm and interruptible services.

Golden Triangle Storage offers customers
  • high-deliverability storage at a liquid market point
  • easy access to multiple supply sources, including liquefied natural gas imports
  • interconnections with six pipelines serving diverse markets with counter-seasonal demand.
Interconnections include
  • Florida Gas Transmission (downstream of station 6)
  • Texas Eastern Transmission (WLA pool)
  • DCP's Centana Intrastate Pipeline
  • Houston Pipe Line's Texoma line
  • Kinder Morgan Texas Pipeline
  • ExxonMobil's Golden Pass Pipeline

    On the supply side, Golden Triangle Storage offers easy access for East and South Texas onshore production, including Barnett Shale, Bossier Sands and Eagle Ford gas, as well as offshore supplies. In addition the facility is conveniently located near LNG import terminals in the Golden Triangle area and along the Sabine-Lake Charles corridor.
