Proposed Coal Plant in Montana Deferred

LCG, December February 4, 2009--Southern Montana Electric (SME)announced Monday that it will defer the development of the 250-MW, Highwood Generating Station. The coal-fired project was planned to have been built near Great Falls.

SME now plans to install a 120-MW, gas-fired electric generating facility, together with over 6 MW of generating capacity driven by wind power. The initial, 80-MW phase of the gas-fired facility is scheduled to be operational toward the end of 2011, with an additional 40-MW of capacity coming on-line within the next 12 months.

SME's deferral of the coal-fired power plant resulted from a variety of factors, including: legal challenges, regulatory uncertainty with respect to carbon emissions and related global warming concerns, and hurdles associated with financing the project, which has grown to an estimated cost of $900 million.
