Montana: Hydro Power

PPL Montana has officially launched a new 60 MW powerhouse,
. . . at its Rainbow Dam hydroelectric facility near Great Falls,
. . . after completing $209 million in renovations to the 1910 facility.

Hydropower continues to offer promise and potential.
. . . Modernization and upgrades to existing facilities,
. . . offer an opportunity to increase capacity,
. . . . without the need for construction of new, large dams.
The new facility boosts
. . . the century-old Rainbow Dam's generating capacity by 70%,
. . . more power than the old powerhouse's 8 units combined,
. . . with just one unit.
