CHEYENNE, Wyo., Dec. 2, 2013 - Black Hills Corp. (BKH) subsidiary Cheyenne Light, Fuel and Power today filed rate requests with the Wyoming Public Service Commission to increase the utility`s electric and natural gas system revenues to recover investments in electric and natural gas infrastructure, including the Cheyenne Prairie Generating Station.

If approved as filed, the new electric and natural gas rates will generate an estimated $14 million per year in additional revenue, based on an aggregate capital structure of 54 percent equity and 46 percent debt. The filing seeks a return on equity of 10.25 percent for investments the company has made in its electric and natural gas systems. The primary component of the electric filing is Cheyenne Light`s portion of construction and operating costs for a new generating station.

The $222 million Cheyenne Prairie Generating Station is under construction in Cheyenne and will be co-owned by Cheyenne Light and another Black Hills Corp. utility, Black Hills Power.

"Our goal is to provide cost-effective energy for our customers while delivering an appropriate return for our investors," said Linn Evans, Black Hills Corp.`s president and chief operating officer of utilities. "These investments ensure our customers can continue to depend on us for safe, reliable electric and natural gas service that supports continued community growth and the increasing demand for energy."

Cheyenne Light seeks to recover a return on its $127 million share of the new plant and associated infrastructure and recover its share of operating expenses. Black Hills Power, an electric service provider to the Black Hills region of South Dakota and Wyoming, will file a request within the next several months to recover a return on its approximately $95 million share of the plant.

"The Cheyenne Light/Black Hills Power partnership benefits customers of both utilities, in part by creating economies of scale that share construction and operating costs for the 132-megawatt Cheyenne Prairie Generating Station," Evans said. "Natural gas fired generation has relatively low air emissions and is an effective solution to meeting increasingly strict U.S. Environmental Protection Agency air emission standards."

The Cheyenne Light rate requests seeks to implement the natural gas and electric rate increases when the plant is placed into service, scheduled for Oct. 1, 2014. The Wyoming PSC and its staff will conduct an extensive review of the rate plans, a process that considers public comments and includes testimony from utility representatives, the Wyoming Office of Consumer Advocate and other interested parties.
