Rapid City, SD-based Black Hills Corp. has completed the acquisition of a Wyoming natural gas utility, Energy West Wyoming, and related gas pipeline assets for approximately $17 million. The utility and pipelines were part of Montana-based Gas Natural Inc., which owns several Energy West subsidiaries. The acquired gas distribution utility serves Cody, Meeteetse and Ralston, WY, and the pipelines acquired include 30 miles of transmission pipeline and 42 miles of gathering pipelines, both near the utility service area in Park County in northwest Wyoming.

NiSource Inc. and Columbia Pipeline Group (CPG) have completed their separation, with CPG now trading as a separate company on the New York Stock Exchange (NYSE) under the symbol "CPGX." NiSource, based in Merrillville, IN, remains one of the largest natural gas utility companies in the country, serving more than 3.5 million customers in seven states under the Columbia Gas and NIPSCO brands. The company also provides electric distribution, generation and transmission services for about 500,000 NIPSCO electric customers in northern Indiana. NiSource will continue to be listed on the NYSE under ticker "NI." CPG, based in Houston, includes Columbia Gas Transmission, Columbia Gulf Transmission, Columbia Midstream Group, its ownership interest in Columbia Pipeline Partners LP, and other natural gas pipeline, storage and midstream holdings previously owned by NiSource. CPG operates more than 15,000 miles of natural gas transmission pipelines, nearly 300 Bcf of underground gas storage working capacity, and a portfolio of midstream and related facilities.
