• Companies like Xcel Energy and Duke Energy have also been making significant investments in grid modernization and renewable energy integration, which often lead to rate increase requests.
• The specific rate increases requested by NorthWestern Energy will need to be evaluated by regulators based on the company's cost of service and the reasonableness of their investments.
