You’ve probably driven past it if you've ever spent time near Berwick, Pennsylvania. Those two massive cooling towers dominating the horizon aren't just scenery; they are basically the beating heart of the regional power grid. The Susquehanna Nuclear Power Station is a beast. It sits on about 1,100 acres in Salem Township and produces a staggering amount of carbon-free electricity—enough to power millions of homes. But lately, the conversation around this plant has shifted from "how does it work" to "who is buying the power," and that's where things get really interesting for the economy and your electric bill.
Nuclear energy is having a moment.
For years, plants like Susquehanna were seen as aging relics of a different era. People talked about decommissioning and the "nuclear sunset." Then, the AI boom hit. Suddenly, the world's biggest tech companies realized they needed an ungodly amount of electricity to run data centers, and they needed it to be "green" to hit their corporate ESG goals. Susquehanna found itself right in the middle of a bidding war.
Why the Susquehanna Nuclear Power Station is Suddenly the Hottest Asset in PA
It’s about reliability. Wind and solar are great, but the sun goes down and the wind dies. A nuclear reactor doesn't care. It just hums along at a 90% plus capacity factor.
The station uses two General Electric Boiling Water Reactors (BWRs). Unit 1 started up in 1983, and Unit 2 followed in 1985. Talen Energy owns 90% of it, while Allegheny Electric Cooperative holds the other 10%. Here’s the kicker: in early 2024, Talen made a massive deal with Amazon Web Services (AWS). They sold a data center campus right next to the plant to Amazon for $650 million.
This isn't just a real estate play.
Amazon is basically plugging their servers directly into the nuclear plant. It’s called "behind-the-meter" power. By doing this, they bypass a lot of the grid congestion issues that plague other developers. However, it’s not without drama. Other utilities like Exelon and American Electric Power (AEP) filed formal protests with the Federal Energy Regulatory Commission (FERC). They’re worried that if big tech gobbles up all the "firm" power from plants like the Susquehanna Nuclear Power Station, regular people—homeowners and small businesses—will be left footing the bill for grid upgrades or facing higher prices during peak demand.
Honestly, it’s a mess. A high-stakes, multi-billion dollar mess.
Breaking Down the Tech: BWR vs. Everything Else
Most people hear "nuclear" and think of the Simpsons or Chernobyl. That's a mistake. The Susquehanna plant uses Boiling Water Reactor technology, which is fundamentally different from the Pressurized Water Reactors (PWRs) you see at places like Three Mile Island.

In a BWR, the water that cools the reactor core actually turns to steam and goes directly to the turbine. It’s a simpler cycle in some ways. You have the reactor vessel, the steam separators, and then the massive turbines that spin to create juice. The Susquehanna units have been uprated several times over the decades. An "uprate" is basically a turbo-boost for a nuclear plant. By swapping out old components for more efficient ones, engineers squeezed more megawatts out of the same footprint.
Today, the plant generates about 2,500 megawatts.
That is a ton of power. For context, a large solar farm might do 100 or 200 megawatts on a perfect day. Susquehanna does 2,500 every single day, rain or shine, for roughly 18 to 24 months at a time before they have to shut down for refueling. During those refueling outages, the local economy in Berwick and Luzerne County explodes. Thousands of specialized contractors descend on the area. Hotels fill up. Diners have hour-long waits. It’s a massive seasonal stimulus package for Northeast Pennsylvania.
The Safety Reality Check
Let’s talk about the elephant in the room: safety.
Living near a nuclear plant makes people nervous. It’s a natural reaction. But if you look at the data from the Nuclear Regulatory Commission (NRC), Susquehanna is consistently one of the most scrutinized industrial sites in the country. They have "resident inspectors" who literally work at the plant every day, employed by the government, just to watch over the operator's shoulder.
They use a "defense-in-depth" strategy. This means multiple redundant systems. If Pump A fails, Pump B starts. If Pump B fails, Pump C is waiting. If the power grid goes down, they have massive diesel generators that can keep the cooling systems running for days. They even have "FLEX" equipment—portable pumps and generators stored in reinforced buildings—added after the Fukushima incident in Japan to ensure they can handle a "beyond-design-basis" event.
Is it perfectly safe? Nothing is. But compared to the air pollution from coal or the environmental footprint of gas extraction, the trade-off is something many locals have accepted for forty years.
The Economic Engine Nobody Sees
Most people focus on the electricity, but the Susquehanna Nuclear Power Station is a massive employer. We’re talking about 900+ high-paying jobs. These aren't just "jobs," they are "buy a house and put three kids through college" careers.

The tax revenue is another layer. The plant pays millions in local property taxes. In rural Pennsylvania, that money is the difference between a school district having a robotics lab or having to cut the music program. When there was talk a few years ago about nuclear plants struggling to compete with cheap natural gas, the local community got very quiet, very fast. The thought of losing Susquehanna was, and is, terrifying for the local economy.
Environmental Impact: The River and the Air
One weird thing about nuclear plants is that they are surprisingly "natural" on the outside. Because the site is so large and high-security, much of the 1,100 acres is actually a de facto nature preserve. You’ll see deer, eagles, and all sorts of wildlife thriving just a few hundred yards from the reactor containment buildings.
The plant uses the Susquehanna River for cooling.
They take water in, use it to condense the steam back into water, and then release it. A common misconception is that this water is radioactive. It’s not. It stays in a separate loop. The biggest concern is usually "thermal pollution"—the idea that the water being pumped back into the river is too warm for the fish. The plant uses those iconic cooling towers to dissipate most of that heat into the atmosphere before the water ever touches the river again. That "smoke" you see coming out of the towers? It's just water vapor. Pure steam.
What Most People Get Wrong About Nuclear Waste
"What about the waste?" It's the first question everyone asks.
Right now, the spent fuel from the Susquehanna Nuclear Power Station is stored right there on-site. First, it goes into deep pools of water to cool down for several years. Once it’s cool enough, it gets moved into "Dry Cask Storage." These are massive concrete and steel canisters sitting on a reinforced pad.
They are built to withstand almost anything—plane crashes, earthquakes, floods.
Is it a permanent solution? No. The U.S. government was supposed to have a central repository at Yucca Mountain, but politics killed that project. So, for now, the waste stays at the plant. It sounds scary, but it’s actually a very small amount of material. If you took all the electricity you used in your entire life and got it solely from nuclear power, the resulting waste would fit into a soda can.
The Future: Will Susquehanna Power Your Next AI Prompt?
The deal with Amazon changed the game. It proved that nuclear power isn't just a "grid" asset anymore; it's a "tech" asset.
We are seeing a trend called "re-nuclearization." Companies are looking at old plants and wondering if they can restart them (like the Palisades plant in Michigan) or if they can expand existing ones. While there are no current plans to build a "Unit 3" at Susquehanna, the existing units are being pushed to their absolute limits of efficiency.
The battle over who gets this power is just beginning. As more data centers move into the "Silicon Reach" of Pennsylvania, the tension between industrial needs and public utility will grow.
You’ve got to realize that the Susquehanna Nuclear Power Station is no longer just a local power plant. It is a pivot point for the American economy. It represents the collision of 1970s heavy engineering and 2020s digital expansion.
Actionable Insights for the Future
If you live in the area or are looking at the energy sector, here is what you need to keep an eye on:
- Monitor FERC Rulings: The decision on whether Amazon can keep its "behind-the-meter" deal at Susquehanna will set the precedent for the entire country. If FERC blocks it, the value of nuclear plants might dip. If they allow it, expect a land rush.
- Job Opportunities: If you're looking for a stable career, the nuclear industry is desperate for young talent. With the average age of a nuclear worker hovering in the late 40s or 50s, a "silver tsunami" of retirements is coming.
- Local Real Estate: Areas within a 20-mile radius of Susquehanna are seeing increased interest from tech-adjacent companies. Keep an eye on zoning changes in Salem Township and surrounding boroughs.
- Energy Hedging: If you are a business owner in PJM (the grid region covering PA), expect volatility. The transition of large "baseload" plants to private contracts means the remaining grid power might get more expensive during peak times. Look into demand-response programs or onsite solar to hedge your risks.
The Susquehanna Nuclear Power Station has been humming along quietly for forty years. It’s not quiet anymore. It’s the center of the conversation about how we power the future without burning the planet. Whether you love nuclear or hate it, you can't ignore the fact that those two towers in Berwick are more important now than they’ve ever been.
