Montana Wind Is Growing — But It Can’t Fully Replace Coal Yet

As coal plants shut down and coal use ends in many parts of the U.S., wind power in Montana has expanded quickly. But recent reporting shows that wind — although important — is still only part of the solution. Because wind produces less power than coal in practice, the shift leaves a “gap” that requires careful planning and more tools. 

Why Wind Is Growing in Montana

• Montana has huge wind potential. Experts say the state is among the top in the U.S. for wind-power capacity. 
• Over the past several years, several large wind-farm projects — including ones operated by out-of-state utilities — have come online or are under construction. 
• For example, a new wind farm owned by a major utility is planned to start producing in 2025. This helps replace part of the power from a coal plant the utility is abandoning. 
• In 2022, wind accounted for roughly 15 % of Montana’s electricity generation, while coal still produced about 43 %.

So the shift is real — wind is rising while coal is fading.

But Wind Can’t Match Coal — Here’s Why

Shifting from coal to wind is not as simple as “swap one for the other.” There are several key reasons wind falls short of coal when it comes to reliably powering homes and businesses.

Lower “Capacity Factor”

• “Nameplate capacity” — the maximum possible output of a wind farm under ideal conditions — may look good on paper. In fact, Montana is projected to have wind-capacity numbers that match or exceed coal’s nameplate capacity once new wind farms complete. 
• But real-world energy output depends on whether the wind is blowing. Coal plants — while polluting — can run steadily and provide “base load” power. Wind farms cannot guarantee that. As a result, coal still generates a bigger share of electricity than wind in practice.

Transmission & Grid Challenges

• Many Montana wind farms are far from city centers or demand zones. Transmitting electricity long distances requires infrastructure — transmission lines, grid upgrades — that must keep pace. 
• Also: wind power fluctuates with weather, and that variability can strain a grid unless there is storage or backup in place. As one regional report recently warned, during extreme weather — or when hydropower is weak — the broader grid (e.g. in the Pacific Northwest) could face energy shortages unless supply buffers are built.

Jobs, Local Economy, and Social Impact

• Coal has long supported local economies — mines, power plants, stable jobs. When coal declines, many of those jobs disappear. Renewable energy projects often don’t create the same number of long-term jobs. 
• Communities that depended on coal must adapt — but wind farms alone don’t always offer enough work or economic stability to replace what coal once did.

What This Means for Energy Policy & the Region

Given the strengths — and limits — of wind energy, here’s what experts say needs to happen to make the transition work:

• Build energy storage and backup sources. Because wind is intermittent, storage (batteries or other systems) or reliable backup (hydro, gas, etc.) is necessary so supply stays stable. 
• Upgrade transmission lines and grid infrastructure. Transporting wind energy from remote Montana plains to demand centers needs good, robust transmission — or else energy can be wasted or lost. 
• Support communities affected by coal decline. Provide training, job-transition support, and economic aid to people who lose coal-related jobs. 
• Use a mix of energy sources. Wind helps, but it cannot yet meet all energy needs alone. A wise mix — wind, hydro, some natural-gas or other stable sources — may help balance reliability and decarbonization. 
• Plan for long-term demand growth. With increasing electricity demand (because of data centers, electrification, population growth), the system needs foresight so renewables + backup can cover more than just today’s needs.

Conclusion: Wind Helps — But It’s Only Part of the Answer

Montana’s wind-power growth tells a hopeful story: a state once dominated by coal is investing in clean, renewable energy. But as the latest reporting shows, wind — by itself — cannot yet replace coal’s reliability, output and economic role.

Wind provides an important bridge toward cleaner energy, but to avoid power gaps, economic disruption, and instability — it must be paired with smart infrastructure, balanced energy planning, and community support.

The shift is underway — but getting it right will require more than good intentions. It will require careful planning, investment, and long-term commitment.
