Montana Project To Increase Generating Capacity


PPL Montana has received approval from FERC to generate more power at the Rainbow development, one of nine hydroelectric developments in its Missouri-Madison project (P-2188).The license amendment approved last week will now allow expansion of the project by constructing a new powerhouse and adding two new turbines with a total generating capacity of 58 MW. The powerhouse currently has one 35 MW turbine, which will have to be decommissioned under the conditions.FERC issued an EA in February concluding that the actions proposed by the licensee would not create any significant impacts. Among other things, PPL Montana has proposed to construct a new powerhouse and a new intake structure.The Missouri-Madison project consists of nine developments on the Madison and Missouri Rivers in Gallatin, Madison, Lewis and Clark, and Cascade Counties, in southwestern Montana. The total generation capacity of the nine developments is 327MW.
