The pipelines, which have been acquired from Onyx Midstream and Onyx Pipeline, transport natural gas to two power plants in Nueces county, Texas under fixed-fee contracts that extend through 2029.

The pipelines, which range from 12in to 24in in diameter, include the total length of around 50 miles, noted Southcross.

According to Southcross, during 2013, natural gas volumes through the pipelines averaged 97 million cubic feet per day.

Southcross Energy Partners chairman and CEO David Biegler said the acquisition of the pipelines is expanding platform of the company.

"They complement our integrated midstream strategy of delivering products to end-use markets and customers and are significant additions to our pipelines in the Corpus Christi area," Biegler added.
