MERRILLVILLE, Ind., March 21, 2016 /PRNewswire/ -- On Friday, March 18, Columbia Gas of Pennsylvania, Inc., a subsidiary of NiSource Inc. (NYSE: NI), filed a request with the Pennsylvania Public Utility Commission (PUC) to adjust its base rates for distribution service so it can continue to upgrade and replace the Company's underground natural gas distribution pipelines.

'Our number one priority is maintaining the safety of our customers and the communities we serve,' said Mark Kempic, president of Columbia Gas of Pennsylvania. 'We have made, and will continue to make, substantial capital investments in our system to enhance the safe and reliable system that we currently operate. We believe this filing provides a number of tangible benefits to our customers.'

From 2007 - 2015, Columbia Gas of Pennsylvania invested nearly $1.1 billion to modernize and expand its distribution system in Pennsylvania. Of that amount, approximately $845 million was dedicated to replacing over 744 miles of priority pipe. In 2016 alone, Columbia Gas of Pennsylvania will invest $210 million in Pennsylvania, with more than $160 million dedicated to upgrading aging underground infrastructure across its 26-county service territory.

'We are proud of our pipeline replacement program and our ability to continue to serve our valued customers safely and reliably, but our work doesn't stop there,' said Columbia Gas of Pennsylvania Vice President and General Manager Mike Davidson. 'We also remain committed to providing a positive customer experience through an educated and trained workforce focused on safely meeting or exceeding all federal and state requirements while operating our distribution system.'

The filing, if approved by the PUC, would not only provide the Company with an opportunity to earn a fair return on its infrastructure capital investments, but also enhance pipeline safety through a number of initiatives.

'Multiple new pipeline safety rules and advisories are changing the manner in which we operate and will require additional training and new operating standards,' Davidson noted.

In the filing, Columbia Gas of Pennsylvania is seeking an annual revenue increase of approximately $55 million.

'We are working more efficiently than ever, and we will continue to look for additional ways to make the most cost-effective decisions for our customers,' said Kempic. 'Even with this filing, the total average residential customer bill, when adjusted for inflation, would still be 29 percent lower in 2017 than it was in 2006.'

Approval of the proposal would result in the average total bill for a residential customer who purchases 70 therms of gas per month increasing from $77.33 to $86.97 (12.47 percent), the average total bill for a small commercial customer who purchases 158 therms of gas per month increasing from $128.29 to $139.74 per month (8.93 percent), and the average total bill for a small industrial customer who purchases 1,328 therms of gas per month increasing from $898.47 to $958.60 per month (6.69 percent). These figures represent an annual average monthly bill with the customer purchasing their gas from Columbia Gas of Pennsylvania.

Director of Rates and Regulatory Affairs Nicole Paloney noted, 'The impact on the customer's bill associated with this filing is softened thanks to continued low, stable natural gas costs. On behalf of our customers, we work with suppliers to secure the best possible natural gas prices, while maintaining the reliability of gas supply during peak demand periods.'

Gas costs generally represent about a third of a residential customer's total bill. Columbia Gas of Pennsylvania purchases its gas on the wholesale market and under Pennsylvania law passes these costs on to its customers without mark-up or profit. The gas cost portion of a residential customer's monthly bill is based entirely on their home's monthly gas consumption.

In addition to a wide array of customer assistance and energy efficiency programs that provide resources and tools for customers to save money and energy, the Company also utilizes a Weather Normalization Adjustment (WNA) that stabilizes the distribution portion of a customer's bill to reflect normal weather levels if temperatures are 5% greater or 5% lower than normal during the winter heating season.

The process for a general rate proceeding before the PUC can take up to nine months and the company expects that new rates would be effective at the end of 2016. Customers with questions regarding the proposal may call 1-888-460-4332 or visit the Rate Adjustment Information Center at www.ColumbiaGasPA.com to learn more.
