PUEBLO, Colo., March 14, 2011 /PRNewswire/ -- Black Hills Corp. (NYSE: BKH) subsidiary Black Hills Energy – Colorado Electric today announced it has filed its certificate of public convenience and necessity (CPCN) to construct a General Electric LMS100 natural-gas-fired turbine in accordance with the Colorado Public Utilities Commission's Dec. 15, 2010, order. The order approved the retirement of the company's coal-fired W.N. Clark facility, and granted a "presumption of need" for 42 MW to replace the Clark capacity, under the Colorado Clean Air-Clean Jobs Act, also known as House Bill 1365.
In its CPCN filing, Black Hills Energy seeks approval to construct a third utility-owned GE LMS100 natural gas-fired turbine at its Pueblo Airport Generation Station site in Pueblo, Colo., where the company is currently constructing two GE LMS100 turbines. The filing proposes retiring the utility's two Pueblo steam turbine units, which together produce 29 MW, to justify a portion of the incremental capacity from the proposed GE LMS100 that will be used to serve customers in southern Colorado. The net power output capacity of the proposed GE LMS100 during the summer months is estimated to be 88 MW. An additional 18 MW of capacity need is also derived from the Dec. 31, 2010 expiration of a power swap agreement.
"Although we had no short-term plans to retire any generation before passage of Colorado's Clean Air-Clean Jobs Act, we've worked diligently to determine the most efficient plan to replace the capacity deficit from the 2013 closure of the W.N. Clark facility and expiration of the power swap agreement," said Christopher Burke, vice president of operations, Black Hills Energy – Colorado Electric. "At present, the Pueblo units that have been identified for retirement are primarily operated during July and August when the company experiences its peak demand for electricity. With substantial infrastructure already in place at our Pueblo Airport Generation Station, we can reduce costs associated with constructing and operating the replacement generation as we retire the Pueblo assets."
The two Pueblo steam turbines are 70 and 62-years old, respectively. The age of these units make them more expensive to operate and maintain than a new, efficient, state-of-the-art GE LMS100, which is more cost effective and fuel efficient at providing optimum peaking capacity.
The utility-owned turbine will require a capital investment of approximately $102 million, excluding investment in ancillary facilities such as transmission. Construction of the turbine would begin immediately after receipt of the CPCN and the plant would be operational no later than Dec. 31, 2013, as required by the commission's December order.
The Colorado Clean Air-Clean Jobs Act requires regulated utilities in Colorado to reduce emissions from coal-fired power plants in the state by replacing or repowering with natural gas or other low-emitting energy resources. Specifically, the Act requires all Colorado investor-owned utilities, including Black Hills Energy, to lower nitrous oxide emissions by a minimum of 70 percent on 50 percent of their coal-fired electric generating units in Colorado by the end of 2017.
