ITEM 2. A BRIEF DESCRIPTION OF THE PROPERTIES OF CLAIMANT AND EACH OF ITS SUBSIDIARY PUBLIC UTILITY COMPANIES USED FOR THE GENERATION, TRANSMISSION, AND DISTRIBUTION OF ELECTRIC ENERGY FOR SALE, OR FOR THE PRODUCTION, TRANSMISSION, AND DISTRIBUTION OF NATURAL OR MANUFACTURED GAS, INDICATING THE LOCATION OF PRINCIPAL GENERATING PLANTS, TRANSMISSION LINES, PRODUCING FIELDS, GAS MANUFACTURING PLANTS, AND ELECTRIC AND GAS DISTRIBUTION FACILITIES, INCLUDING ALL SUCH PROPERTIES WHICH ARE OUTSIDE THE STATE IN WHICH CLAIMANT AND ITS SUBSIDIARIES ARE ORGANIZED AND ALL TRANSMISSION OR PIPELINES WHICH DELIVER OR RECEIVE ELECTRIC ENERGY OR GAS AT THE BORDERS OF SUCH STATE. ELECTRIC PROPERTIES The following table provides information on the generation, transmission and distribution facilities of Black Hills Power. Generation Facilities During 1999, 99 percent of the fuel used by Black Hills Power to generate electricity, measured in Btus (British thermal units), was coal. Black Hills Power's generation facilities include: the Ben French Plant in Rapid City, South Dakota, consisting of five 20 MW combustion turbines, a 25 MW coal-fired steam boiler and four 2.5 MW oil-fired internal combustion units; Neil Simpson I and Neil Simpson II near Gillette, Wyoming, coal units with capacities of 21.76 and 88.9 MW, respectively; Osage Plant in Osage, Wyoming, a 34.5 MW coal-fired plant; and the Wyodak Plant (20% share, co-owned with PacifiCorp) near Gillette, Wyoming, at which Black Hills is entitled to 72.4 MW of capacity. Generating Units Name of Plant Year of Rating Principal Installation (Kilowatts) Fuel ------------ ----------- --------- Osage Plant - Osage, (WY) 1948-1952 34,500 Coal Ben French Station-Rapid City, (SD) 1960 25,000 Coal 1965 10,000 Oil 1977-1979 100,000 Oil or gas Neil Simpson Station-Gillette, (WY) 1969 21,760 Coal 1995 88,900 Coal Wyodak Plant - Gillette, (WY) 1978 72,400 Coal ------ Total 352,560 ======= Of the 352.56 MW total installed capacity, 135 MW of Black Hills Power's installed capacity is presently located in South Dakota, with an additional 217.56 MW located in Wyoming due 9

to the abundance of low sulfur coal in that state. By constructing its coal plants in close proximity to their fuel source, Black Hills Power is able to provide economical power to its customers and eliminate the substantial cost of transporting coal by rail to its generating facilities. Transmission and Distribution Facilities Because 97% of Black Hills Power's service territory and 96% of its customers' load is located in South Dakota, 2,064 miles (96%) of Black Hills Power's 2,153 miles of distribution lines are also located in that State, with an 63 additional miles (3%) of distribution lines serving Black Hills Power's Wyoming customers and 26 miles (1%) of distribution lines serving its Montana customers. Black Hills Power owns transmission lines consisting of 447 miles of 230 kV transmission lines, 530 miles of 69 kV lines and 8 miles of 47 kV lines. Black Hills Power also jointly owns 43 miles of 230 kV transmission lines with Basin Electric Power Cooperative. Over six hundred miles of Black Hills Power's transmission lines (59%) are located in South Dakota, with 289 additional line-miles (28%) in Wyoming that are used to transmit the economical power generated by Black Hills Power's mine-mouth coal-fired facilities located in Wyoming to its load centers in South Dakota. Black Hills also owns 40 miles of transmission line (4%) in Montana that are used to serve its customers in that State and 94 miles of transmission line (9%) in Nebraska, the sole purpose of which is to interconnect Black Hills Power with the Western Area Power Administration's facilities in Stegall, Nebraska. In addition to the facilities identified above, Black Hills Power owns a service center in Rapid City, several district office buildings at various locations within its service area and an eight-story home office building in Rapid City, South Dakota, housing its home office on four floors, with the balance of the building rented to others. NON-ELECTRIC ENERGY PROPERTIES Non-electric energy properties consist of coal mining properties, oil and natural gas properties and energy marketing properties. Coal Mining Properties Wyodak Resources is engaged in mining and processing sub-bituminous coal near Gillette in Campbell County, Wyoming, and owns or has user rights in the necessary mining, processing and delivery equipment to fulfill its sales contracts. The coal averages 8,000 Btus per pound. Mining rights to the coal are based upon four federal leases and one state lease. The estimated recoverable coal from the leases as of December 31, 1999 is 277,717,000 tons, of which 19,934,000 tons are committed to be sold to the Wyodak Plant and approximately 24,150,000 tons to Black Hills Power's other plants. 10

Oil and Natural Gas Properties Black Hills Exploration and Production operates 298 wells as of December 31, 1999. The majority of these wells are in the Finn Shurley Field, located in Weston and Niobrara Counties, Wyoming. Black Hills Exploration and Production does not operate, but owns a working interest in 284 producing properties located in the western and southern United States. Black Hills Exploration and Production also owns a 44.7 percent non-operating interest in a natural gas processing plant located at the Finn Shurley Field. Energy Marketing Properties In 1999, Black Hills Energy Resources formed Black Hills Millennium Pipeline Company to own a minority interest in a 200 mile pipeline in Texas. The pipeline has a capacity of 67,000 barrels per day. The majority owner and operator of the pipeline is Equilon Pipeline Company LLC. ITEM 3.
