ENSTOR is developing the ENSTOR Houston Hub Storage project on a salt dome structure located just north of the Houston Ship Channel. This site is ideally located to not only meet the requirements of traditional storage users, but to also assist power generators in their need to manage the growing gas-fired generation and renewables integration markets in Texas (where 45% of today's US renewable power is produced). In addition to firm and interruptible storage services, this facility will be equipped to handle a full slate of hub related services including park and loan opportunities, as well as wheeling to optimize your pipe to pipe dispatch.

ENSTOR Houston Hub Storage will provide customers the opportunity to balance production from the new and growing shale resources in Texas including Barnett, Haynesville, and rich Eagle Ford plays in South Texas. Additionally, should your company be interested in gas liquids storage, Houston Hub's location near Mont Belvieu, TX makes it an ideal site for processors to store various liquids in route to market.

Houston Hub received its FERC certificate in 2008 to provide high deliverability multi-cycle gas storage service. With the current scope, this facility will share all of its pipeline interconnects with Enstor's Katy Storage Hub, one of the largest trading hubs in the country. Enstor Houston Hub will provide access to substantial supply and market from various trading regions, ensuring ample liquidity and flexibility to assist any company with its seasonal, daily and intra-day load balancing needs.
