Paa Natural Gas Storage has filed with the Federal Energy Regulatory Commission (FERC) for expansion of its Pine Prairie natural gas storage facility in the US.

The filing contemplates construction of an additional 32bcf of working gas storage capacity, including two new 12bcf caverns and the expansion of permitted capacity for caverns two through five from 10bcf to 12bcf each.

Paa Natural Gas Storage president Dean Liollio said that this filing helps position the company to meet future customer demand as market conditions warrant, beginning with the 2013 storage season and beyond.

Pine Prairie currently has three operating caverns with 24bcf of working gas capacity, and an additional 18bcf of working gas capacity is currently under construction with approximately 7bcf to 8bcf scheduled to be placed into service in the second quarter of 2011 and about 10bcf in the second quarter of 2012.

Receipt of FERC approval for the proposed expansions will increase Pine Prairie’s permitted capacity from 48bcf to 80bcf.

Paa Natural Gas Storage is engaged in the development, acquisition, operation and commercial management of gas storage facilities.
