RAPID CITY, S.D., March 1 /PRNewswire-FirstCall/ -- Black Hills Corp. subsidiary Black Hills Power made a filing today with the South Dakota Public Utilities Commission requesting interim rates be implemented for electricity service on and after April 1, 2010. The Black Hills Power filing proposes an interim rate increase of $24 million, or approximately 20 percent, for South Dakota electric utility customers. A typical Black Hills Power South Dakota residential customer using 600 kilowatt-hours of power each month will see an interim increase of $12.18 per month, or about 40 cents per day. The interim rate increase will be included in customer bills beginning in April 2010, subject to adjustment once a final order pertaining to Black Hills Power's South Dakota rate request is received from the South Dakota Public Utilities Commission.
"Although we continue to work towards resolution of our rate request filed on September 30, 2009, we do not anticipate receiving a final order from the South Dakota Public Utilities Commission by April 1, 2010. In the event the Commission does not complete its review and issue a final order within six months, South Dakota law allows investor owned utilities to change customer rates on an interim basis, subject to adjustment once a final order is received," said Chuck Loomis, vice president, operations for Black Hills Power. "The implementation of interim rates on April 1, 2010 coincides with the expected commercial operation of the Wygen III generation facility, constructed to serve the growing electricity demand of our Black Hills customers," continued Loomis.
On Sept. 30, 2009, Black Hills Power filed a request for an electric revenue increase with the South Dakota Public Utilities Commission to recover costs associated with the Wygen III power plant located near Gillette, Wyo., and other generation, transmission and distribution assets and increased operating expenses. In its original application, Black Hills Power requested a $32 million increase in annual utility revenues, or approximately 26.6 percent, to be effective on April 1, 2010.
"We understand that any rate increase is difficult for our customers and we want to ensure the interim rates implemented use the best information possible," said Loomis. "As is typical in a regulatory process that extends over a 6 month period or more - following a filing the utility continues operating and there are known and measurable costs that change, and in this case have reduced, the amount requested in Black Hills Power's original application," concluded Loomis.
Black Hills Power's last base rate increase was based on 2005 costs and became effective in January 2007.
