NorthWestern Energy Group (NWE) shared details of its pending merger with Black Hills Corporation in a Montana PBS interview. CEO Brian Bird said customers should see “very little” day‑to‑day change, and that rates will not change as part of the merger; rates only change through a rate review. He highlighted scale benefits such as stronger procurement leverage and reduced duplicative costs, with expected savings to be reflected over time in rate reviews.
Bird will lead the combined company. He noted workforce duplication risks but expects impacts to be handled largely through attrition, citing 5–10% annual attrition and a similar level of anticipated duplication. The company expects greater regulatory and business diversification: today NorthWestern is “85–90% Montana,” while post‑merger Montana would be “just over 30%.” He acknowledged investor focus on Montana approval, given past commission decisions, and emphasized this is a merger of two financially strong utilities.
