Montana-Dakota Utilities files natural gas rate increase request in South Dakota

BISMARCK, N.D. – Sept. 19, 2013 – Montana-Dakota Utilities Co. filed a natural gas rate increase request with the North Dakota Public Service Commission Wednesday. The request represents an overall increase in revenues of 6.4 percent. Montana-Dakota’s last natural gas rate increase, which was 2.1 percent, became effective in October 2004.

“We have worked, and continue to work, extremely hard at watching our operating expenses and looking for ways to be more efficient each day. That is one facet of our business,” said Frank Morehouse, president and chief executive officer of Montana-Dakota. “But we also have made significant investments in our natural gas infrastructure to ensure safe and reliable service to our customers, as well as investments in technology to provide better service.”

The main reason for the rate increase request is to recover the cost of the increased investment in natural gas facilities. In addition to the ongoing investment for new customers and replacing existing facilities, the company has invested in new district operations buildings, an automated meter reading system and a new customer billing system since the last rate increase request.

The proposed increase is for $6.8 million annually over current rates, or a 6.4 percent overall increase. Residential customers’ monthly bills would increase by an average of about $5.15 a month. Montana-Dakota has about 99,000 natural gas customers in 76 North Dakota communities.

Despite the investments, the average operation and maintenance cost per customer is lower today than in 2004.

The proposed increase for each rate class, which is based on rate class studies, is:

  • Residential 9.5 percent
  • Firm general 2.2 percent
  • Air Force 1.2 percent
  • Small interruptible 8.1 percent
  • Large interruptible – no change

The North Dakota PSC has up to seven months to issue a decision on the proposed increase request. Montana-Dakota has also filed a request for an interim rate increase of 4.2 percent, or $4.45 million over current rates, which, if approved, would be implemented while the PSC reviews the overall request. The interim increase would be $2.50 more per month for the average residential customer.
