To accommodate additional supply coming in from the Rockies Express pipeline and from the Midcontinent and Canada, Boardwalk Pipeline Partners LP said Wednesday that subsidiary Texas Gas Transmission LLC is planning a third expansion of its gas storage operations that would add 113,900 MMBtu/d of deliverability and 10.25 trillion Btu of working gas capacity to its total storage operations, which includes nine fields in Indiana and Kentucky.

During the past three years, Texas Gas has conducted two successful storage open seasons that will increase its working gas capacity by 17.5 TBtu. On Nov. 1, 2005, an 8.2 TBtu storage expansion was placed into service. Texas Gas filed a certificate application earlier this year for a 9.3 TBtu storage expansion with an anticipated in-service date of Nov. 1, 2007. The phase two project includes seven new storage wells and 16,888 hp of additional compression that will boost daily deliverability by 100,749 Dth/d. Texas Gas’ total working gas capacity after the first two expansions will be about 72 Bcf.

For the third phase of its storage expansion, Texas Gas is proposing to drill more wells, install compression and install pipeline looping. Depending on market response and regulatory approvals, construction would take place during the spring and summer of 2008, with service beginning Nov. 1, 2008.

The open season began Nov. 6 and ends at 5 p.m. CT on Dec. 15.
