NorthWestern Energy adapts as demands evolve: Brian Bird

For over 100 years, NorthWestern Energy, and its predecessor Montana Power, has been at the heart of Montana’s power infrastructure, providing reliable and affordable energy solutions to residents across the state. As the demands of energy consumers continue to evolve, NorthWestern is constantly adapting to ensure long-term reliability and affordability. A key part of this effort is a proposed regulatory rate review. We appreciate all the local businesses, organizations, and residents who recently testified in favor of the review to help maintain the reliability of energy services while managing the growing challenges posed by extreme weather, wildfires, and increasing demand for power.

Montanans need reliable energy service 24 hours a day, 365 days a year. NorthWestern’s role in meeting that demand is a critical one. We have made significant investments in infrastructure and technology, ensuring that our services meet the high standards of safety, reliability, and efficiency that Montana residents expect. In fact, NorthWestern customers experienced 99.98 percent reliability in 2023, placing the utility in the first quartile of energy companies nationwide. Additionally, energy bills for Montana customers are consistently lower than the national average, thanks to NorthWestern’s efficient operations and careful management.

However, maintaining that high level of reliability, while preparing for future energy needs and extreme weather events, requires continued investment in both infrastructure and technology. The last decade has seen a focus on grid resiliency, a priority that grows ever more important as weather events like wildfires, storms, and cold snaps become more frequent and severe. NorthWestern’s proactive approach includes upgrades to electrical systems, better monitoring through advanced field cameras, and aerial and ground assessments to detect potential issues before they cause damage or disruptions.

Moreover, the utility is working hard to address challenges related to the growing demand for energy. By expanding its capacity for on-demand power and embracing renewable energy sources like wind and solar, NorthWestern is ensuring that it can meet energy needs while also protecting the environment. In fact, about 60 percent of the energy serving NorthWestern’s Montana customers is carbon-free, well above the national average of 40 percent. These initiatives not only help ensure the utility is operating as sustainably as we can but also support efforts to integrate renewable energy into the grid in a way that doesn’t sacrifice reliability.

 One of NorthWestern’s most notable recent investments is the Yellowstone County Generating Station (YCGS), which began serving customers in 2024. This new power station plays a pivotal role in maintaining grid reliability, especially during peak demand periods and extreme weather events. By reducing reliance on higher-cost energy market purchases, YCGS will ultimately help keep rates lower for our customers.

 In addition to providing affordable and reliable power, NorthWestern’s operations are a key economic driver in Montana. In 2024, our company’s activities generated a remarkable $2.59 billion in economic impact, supporting over 15,700 jobs and generating $532.7 million in wages. This economic contribution extends beyond direct employment; NorthWestern also supports $195.3 million in state and local property taxes, which fund essential public services like schools and roads. By ensuring competitive rates and driving economic development, NorthWestern is helping to create new jobs, expand the state’s tax base, and boost the overall economy, benefiting both customers and communities across Montana.

While NorthWestern understands very well that Montanans are facing rising costs across the board, we are working diligently to help those who need assistance with their energy bills. We offer several programs, including payment options, energy assistance referrals, a bill discount for qualified customers and energy efficiency programs. NorthWestern’s energy efficiency initiatives helped customers save enough energy in 2024 to power over 6,500 homes, further supporting efforts to keep costs down.

The request for a regulatory rate adjustment is not one NorthWestern makes lightly, but it is necessary for the utility to continue meeting Montana’s growing energy needs, improving grid resiliency, and ensuring that future generations of Montanans have access to reliable, affordable, and sustainable energy. With ongoing investments and innovative solutions, NorthWestern Energy is meeting these challenges head-on today, while providing lasting benefits to Montana families and businesses alike.
