Tennessee Gas Pipeline Co. has asked the Federal Energy Regulatory Commission for a permit to link the western and eastern parts of its interstate system.

The plan calls for 223 miles of 30 in. crossover line from Tennessee's 100 line near Jonesboro, La., to its 500 line near Heidelberg, Miss., and addition of 29,410 hp of compression.

The $204.2 million west-east crossover would allow Tennessee to move as much as 535 MMcfd of gas from 100 line to 500 line, including volumes from the Bear Creek gas storage site. In addition, the link would cross Tennessee's 800 line and eight other interstate pipelines.

The crossover would improve access system-wide to gas supplies available in the western part of Tennessee's system. The 500 Line has spare capacity, but capacity of the 100 and 800 lines has constrained throughput.

The company said supply shortfalls could occur in the eastern part of its system during the 1990s.

Capacity of the 500 line is 1.9 bcfd near compressor station 538, where the crossover is to intersect.

System capacity is 600 MMcfd at compressor station 860 in northern Tennessee, where the 800 and 500 lines intersect. At station 87 south of Dickson, Tenn., where 800 and 100 lines intersect, capacity is 1.3 bcfd.

The company hopes to have the crossover in service by early 1993.

The Bear Creek storage site has total capacity of 114 bcf, working gas capacity of 65 bcf and a maximum withdrawal rate of 900 MMcfd. Tenneco Gas and Southern Natural Gas Co. each own a 50% interest in Bear Creek.
