1. Accelerated Adoption of Distributed Generation and Energy Storage:

As the costs of rooftop solar photovoltaic (PV) systems and grid-scale or residential battery storage continue to decline, there is an accelerating trend of customers (both residential and commercial) generating and storing their own electricity. This "behind-the-meter" generation reduces the amount of electricity customers purchase from NorthWestern Energy's grid, directly impacting the utility's sales volumes and traditional revenue model. This trend threatens the utility's core business of selling electricity from centralized power plants by empowering customers to achieve greater energy independence.

2. Increased Regulatory and Societal Pressure for Decarbonization:

NorthWestern Energy operates a generation portfolio that includes significant coal-fired assets. There is escalating regulatory, governmental, and societal pressure to accelerate the transition away from fossil fuels and achieve net-zero carbon emissions. This emerging threat could mandate the premature retirement of existing, long-lived generation assets, necessitate massive capital expenditures for new renewable energy projects and associated transmission infrastructure, and impose complex challenges related to maintaining grid reliability and ensuring cost recovery, fundamentally altering NWE's asset base and business strategy.

NorthWestern Energy (NWE) operates primarily in the electricity and natural gas sectors across Montana, South Dakota, Nebraska, and Yellowstone National Park.

Electricity Market

• Montana: The total retail sales for electricity in Montana were approximately 15,504,699 megawatt-hours (MWh) in 2023. The average residential electricity rate in Montana was 12.50 cents per kilowatt-hour in 2025.

• South Dakota: The total retail sales for electricity in South Dakota were approximately 13,505,999 MWh in 2023. The average state electricity rate was 13.18 cents per kilowatt-hour. NorthWestern Energy serves more than 64,700 retail electricity customers in 116 communities across 25 counties in South Dakota.
• Nebraska: NorthWestern Energy primarily provides natural gas services in Nebraska and does not have a significant presence in the electricity market due to Nebraska being the only state where all electricity providers are publicly-owned.

Natural Gas Market

• Montana: Customers in Montana consumed approximately 86.0 billion cubic feet (Bcf) of natural gas annually. For year-end 2024, retail natural gas supply requirements were approximately 22.4 Bcf. NorthWestern Energy is the largest natural gas provider in Montana, accounting for about 60% of all regulated sales and serving approximately 214,500 natural gas customers.

Expected Revenue Growth Drivers for NorthWestern Energy (NWE) Over the Next 2-3 Years

NorthWestern Energy (NWE) is anticipated to drive future revenue growth over the next two to three years through a combination of strategic initiatives and market dynamics. Key drivers include significant rate base investments, successful rate case outcomes, increasing customer and load growth (particularly from data centers), strategic acquisitions, and growth in electric transmission revenues.

1. Rate Base Growth and Capital Investments: NorthWestern Energy plans substantial capital expenditures to expand and modernize its infrastructure. The company has announced a $2.7 billion capital investment plan for 2025-2029, projected to support a 4% to 6% long-term rate base growth rate. This includes major projects such as the 175-megawatt natural gas-fired Yellowstone County Generating Station, which began serving customers in October 2024 and contributes to the rate base. Additionally, the company is investing in regional transmission projects, including its $21 million share in the North Plains Connector project. These investments are crucial for ensuring reliable service and are designed to be recovered through rate adjustments.
2. Rate Increases and Regulatory Outcomes: A significant driver of revenue growth for NWE comes from ongoing rate review activities across its service territories. The company has actively pursued and received approvals for rate increases in Montana, South Dakota, and Nebraska. For instance, NWE filed a Montana electric and natural gas rate review in July 2024, seeking substantial annual revenue increases for both electric and natural gas services. Similarly, natural gas rate reviews were filed in South Dakota and Nebraska, with the latter resulting in a settlement providing $23.9 million in new annual revenue, effective January 1, 2026. New base rates in Montana and South Dakota were primary contributors to increased net income and gross margin in 2024.
3. Customer and Load Growth, Including Data Centers: NorthWestern Energy anticipates revenue growth from an expanding customer base and increased energy demand. Analysts project NWE's revenue to rise by 5.5% annually over the next three years, largely fueled by the anticipated power demand from expanding data center activity in Montana and South Dakota. The electrification of industry and digital infrastructure is expected to provide a strong foundation for sustained revenue and earnings momentum. The company specifically targets 500 MW of data center demand by 2029, which is expected to exceed 10% of total EPS by 2028, with a pipeline exceeding 3 GW and new sites coming online as early as 2026.
4. Strategic Acquisitions and Mergers: NWE is expanding its market reach through strategic acquisitions. The company completed the acquisition of Energy West Montana's natural gas distribution system in July 2025, adding 33,000 customers. Furthermore, NorthWestern Energy entered an agreement to acquire Puget's 370-megawatt ownership in Colstrip at no cost, with a transfer date of December 31, 2025. Revenues from this acquisition are expected to offset associated operating and maintenance costs. The pending all-stock merger with Black Hills Corporation, valued at $3.6 billion, is also positioned to significantly expand NWE's market and diversify its customer and geographic footprint.
5. Electric Transmission Revenues: Growth in electric transmission revenues has been a consistent contributor to NWE's financial performance. Increased electric transmission revenues were cited as a key factor in the company's improved net income and consolidated gross margin in 2024 and the third quarter of both 2024 and 2025. NWE's plans to invest in regional transmission projects further underscore this as an ongoing area of revenue generation.
