CenterPoint Energy, a prominent energy provider in Louisiana, has 118 miles of cast-iron pipelines and 408 miles of bare steel pipelines throughout the state, reports Vickie Welborn for The Shreveport Times. Cast-iron and bare steel pipelines have made recent headlines for their old age and higher risk of incidents such as leaks and explosions.
Louisiana has a higher percentage of these aging pipelines than many states, which has resulted in a greater number of incidents in recent history. However, CenterPoint’s number of leaks, according to a 2013 report, nearly matches the national average. For every 1,000 miles of pipeline owned by the company, there are about 35.65 leaks. The national average falls just below at 35.18. However, the national average percent of gas leaked is 2.29, whereas CenterPoint reported a lost of 5.2 percent, more than twice the national level.
In the past 30 years, CenterPoint has worked to improve its pipeline infrastructure, replacing over 1,700 miles of cast-iron lines and 2,116 miles of bare steel lines.
Louisiana has the most natural gas pipelines of any state in the U.S. with over 50,000 miles total.
