Drive just south of Nebraska City along the Missouri River and you can’t miss it. The massive stacks of the Nebraska City Station dominate the skyline, a gray and tan industrial titan sitting amidst the rolling cornfields. It’s huge. It’s loud. And frankly, it’s one of the most polarizing pieces of infrastructure in the state.
Omaha Public Power District (OPPD) owns this behemoth. While most of the country is screaming about a total transition to renewables, this facility just keeps humming along, providing a massive chunk of the baseload power that keeps lights on from Omaha to the rural corners of the state. It isn't just one plant, though. It’s two distinct units—Unit 1 and Unit 2—built decades apart and operating under very different sets of rules and expectations.
People often forget how much we rely on these "dinosaurs." When the wind stops blowing across the plains or a polar vortex freezes the grid, the Nebraska City Station is usually what keeps your furnace running. It’s a workhorse. But it’s a workhorse with a complicated future, especially as the board at OPPD navigates their goal of being "net zero" by 2050.
The Tale of Two Units at the Nebraska City Power Plant
The history here is a bit of a zigzag. Unit 1 kicked off back in 1979. It’s a 600-megawatt coal-fired unit that reflects the engineering of its time—built for durability and raw output. For over forty years, it has been the backbone of the system. Then you have Unit 2. It didn’t come online until 2009. That’s relatively "new" in the world of power plants.
Unit 2 was a big deal. It added about 685 megawatts of capacity. Because it was built much later, it uses supercritical technology. Basically, it operates at higher temperatures and pressures than Unit 1, which makes it way more efficient. It squeezes more energy out of every ton of coal, which is why OPPD leans on it so heavily today.
But here’s the kicker: Unit 1 is aging. Maintaining a 45-year-old coal plant is like keeping a 1970s semi-truck on the road for 24/7 hauls. It’s expensive. Parts have to be custom-fabricated. The environmental regulations are getting tighter, and the costs of scrubbing emissions are starting to rival the cost of just building something new.

Why Coal Still Sticks Around
You’ve probably heard that coal is dead. In many parts of the U.S., it is. But in the Midwest? It’s more of a slow fade. The Nebraska City Power Plant relies on sub-bituminous coal, mostly shipped in via rail from the Powder River Basin in Wyoming. It’s low-sulfur coal, which helps with emissions, but it’s still coal.
Why hasn't OPPD just flipped the switch? Reliability.
Grid stability isn't a joke. You can't just replace a 1,300-megawatt coal facility with a few wind turbines and call it a day. You need "firm" power—electricity that’s there whether the sun is up or the wind is howling at 40 mph. Until battery storage technology catches up to the scale of an entire regional grid, plants like Nebraska City remain the "insurance policy" for the Missouri Valley.
Environmental Pressure and the Carbon Question
The elephant in the room is carbon dioxide. There’s no way around it—burning coal produces CO2. OPPD is very aware of this. They’ve been under immense pressure from environmental groups and a younger generation of ratepayers to move faster toward decarbonization.
They’ve made some moves. They retired the North Omaha coal units or converted them to natural gas. But Nebraska City is different. It’s too big to just turn off without a massive, multi-billion dollar replacement plan already in place.

If you look at the numbers, Unit 2 is actually one of the cleanest coal units in the country for its size. It has high-end scrubbers and baghouses to catch particulate matter. But "clean coal" is a relative term. It still emits significantly more than a natural gas plant and obviously way more than solar or wind.
The debate in the boardrooms isn't about if they should move away from coal, but when. If they close it too early, they risk blackouts and massive price hikes. If they keep it open too long, they miss their climate targets and potentially face federal penalties. It’s a tightrope walk.
The Economic Ripple Effect
We also have to talk about the money. Nebraska City is the county seat of Otoe County. The power plant is a massive taxpayer. It employs hundreds of people—engineers, mechanics, rail yard workers, and administrative staff. These are high-paying, "head of household" jobs.
If that plant shuts down tomorrow, Nebraska City takes a gut punch. The local school districts rely on those tax dollars. The small businesses downtown rely on those workers buying lunch and gas. This is the "human" side of the energy transition that often gets ignored in white papers written in D.C. or Lincoln.
Reliability During the "Big Freeze"
Remember February 2021? The Winter Storm Uri? That was the moment the Nebraska City Power Plant proved its worth to a lot of skeptics. While Texas was experiencing a catastrophic grid failure, Nebraska and the surrounding states in the Southwest Power Pool (SPP) managed to keep things relatively stable.

Why? Because the coal piles at Nebraska City were sitting right there.
Natural gas prices skyrocketed during that storm because pipes were freezing and demand was insane. Wind turbines were icing up. But the Nebraska City Station stayed online. It was pumping out power at a time when the grid was literally on the edge of collapse. For the people who live in Omaha and Council Bluffs, that plant was the difference between a cold night and a life-threatening emergency.
What Happens Next for Nebraska City?
The future is murky, but we can see the outlines. OPPD has been moving toward a "Power with Purpose" plan. They are adding massive amounts of solar—we’re talking hundreds of megawatts across the region. They are also looking at natural gas backup facilities that can spool up quickly.
But the Nebraska City units are still in the long-term projections. Unit 2, specifically, is likely to stay in operation well into the 2030s, if not longer. It’s simply too efficient and too reliable to scrap while the rest of the energy infrastructure is in flux.
We might see a shift in how it's used, though. Instead of running at 100% capacity all the time, it might become a "peaking" resource or a seasonal backup. Use it in the dead of winter and the heat of summer, and let the renewables take the load during the mild spring and fall months.
Actionable Insights for the Future
If you’re a resident, a business owner, or just someone interested in the local energy landscape, here is how you should be looking at the Nebraska City situation:
- Watch the Integrated Resource Plan (IRP): OPPD updates their IRP regularly. This is where they officially state when they plan to retire units. If you want to know the "expiration date" for coal in Nebraska City, this document is your source of truth.
- Monitor the Southwest Power Pool (SPP) Trends: Nebraska City doesn't just serve OPPD; it’s part of a massive regional market. The decisions made by the SPP regarding "resource adequacy" will dictate whether Nebraska City stays open. If the region is short on power, the plant stays.
- Engage with the OPPD Board: Unlike private utilities, OPPD is governed by an elected board. They actually have to listen to you. If you have feelings about the balance between coal reliability and clean energy, the public board meetings are where that reality is hammered out.
- Prepare for Rate Changes: Transitions are expensive. Replacing the output of Nebraska City with new tech will eventually show up on your bill. Efficiency upgrades in your own home or business aren't just "green"—they are a hedge against the inevitable rising costs of a changing grid.
The Nebraska City Power Plant isn't just a relic of the industrial age. It’s a massive, complex, and vital part of how life in the Midwest actually functions. It’s easy to look at the smoke stacks and think "old tech," but until we find a way to store the wind and sun for a week-long blizzard, those stacks will likely keep right on smoking.
