Black Hills files rate plans to recover system investment, adress new station

Black Hills Power, one of seven utility subsidiaries of Rapid-City-based Black Hills filed two rate plans on Monday with the South Dakota Public Utilities Commission. One plan will allow the utility to recover recent system investments through a revenue increase and the other to begin recovering financing costs for a new power plant that will be placed in service in late 2014. The requested revenue increase is the first such filing for Black Hills Power in three years. As filed, new rates would go into effect April 1, 2013, and would increase the bill for a typical residential customer about $7 per month or an increase of about 24c per day.
