MERRILLVILLE, Ind., May 27, 2016 /PRNewswire/ -- Columbia Gas of Kentucky, a subsidiary of NiSource Inc. (NYSE: NI), has filed today with the Kentucky Public Service Commission (PSC) a request to recover investments and other costs associated with the company's ongoing proactive initiatives to improve the overall safety and reliability of its natural gas distribution system. The company last filed a request to increase rates in 2013.

'Safety is the top priority for Columbia Gas of Kentucky and is the focal point of this request,' said Columbia Gas of Kentucky President Herbert A. Miller, Jr. 'Our customers and our communities rely on the safety and reliability of our system and the well-trained staff that stands ready to serve them 24 hours a day, 7 days a week.'

In 2008, Columbia initiated an Accelerated Main Replacement Program (AMRP) as a proactive approach to replace aging infrastructure. Since the program began, Columbia has invested approximately $92 million and replaced approximately 108 miles or 570,240 feet of aging main lines and associated service lines. Costs associated with this program have appeared as a line item on customer bills, which would be rolled up into the base rates as a part of this request. The AMRP line item would decrease to zero.

Columbia's request also includes funds for a new local training center that is designed to provide employees with enhanced training and operator qualification programs. Technology advances would also be implemented for location and inspection of pipelines as well as emergency notification and response.

In addition to continued system safety and reliability, customers would benefit from an improved online experience driven by technology advances, including enhancements to the company's online bill payment process.

Columbia is requesting an overall increase in revenues of $25.4 million. This translates to an increase of about $11.35 on an average residential customer's monthly bill and an increase of about $37.32 on an average commercial customer's monthly bill.

The company's Gas Supply Cost, which can represent as much as 50 percent of the customer's monthly bill, remains at its lowest level in over 20 years. 'Historically low and sustained natural gas commodity prices have helped keep customer bills low,' Miller said. 'With these proposed changes, a residential customer's average monthly bill will still be almost $25 less than in 2008.'
