On Sept. 28, 2018, NorthWestern Energy filed for an electric rate review with the Montana Public Service Commission. NorthWestern is asking for an increase in electric rates. This is the first NorthWestern Energy general rate review request since 2009. In that period, we have invested more than $850 million in improvements to our Montana electric system. We believe these investments will help us better serve our customers for many years to come.
