New Jersey is a weird place for energy. We've got massive offshore wind projects hitting snags, a grid that feels the squeeze every time a heatwave rolls through, and a surprisingly heavy reliance on split atoms. If you look at a map of South Jersey, specifically Artificial Island in Lower Alloways Creek, you’ll find the heart of the state’s power. This isn't just some local utility curiosity. The nuclear power plant NJ footprint is massive. It provides roughly 40% of the state's electricity and about 90% of its carbon-free energy. That’s huge.
Most people drive past the cooling towers on the way to the Delaware Memorial Bridge and don't give them a second thought. But right now, these plants are at the center of a massive debate involving billions of dollars in subsidies, aging infrastructure, and the state’s aggressive "100% clean energy by 2035" goal.
The Giants on Artificial Island
Let’s get the names straight. When people talk about a nuclear power plant in NJ, they’re usually talking about the Salem and Hope Creek Generating Stations. They sit right next to each other. PSEG Nuclear operates them, and they are essentially the workhorses of the Mid-Atlantic power grid.
Salem has two pressurized water reactors. Hope Creek has one boiling water reactor. Together, they pump out enough juice to power millions of homes. It’s not just about the lightbulbs, though. These plants represent a massive chunk of the South Jersey economy. We’re talking thousands of high-paying jobs in a region that, frankly, needs them. If these plants went dark tomorrow, the economic ripple effect would be devastating for Salem County.
Why Oyster Creek Left a Hole
You can't talk about Jersey nuclear without mentioning Oyster Creek. Located in Forked River, it was the oldest operating commercial nuclear power plant in the United States until it shut down in 2018. When it closed, the state lost a significant chunk of zero-emission power.
The shutdown wasn't because the plant was "broken." It was mostly about the cost of cooling towers. The state wanted Holtec (the current owner for decommissioning) or the previous owners to build massive cooling towers to protect the local fish and water temps in Barnegat Bay. The price tag was too high. So, it closed. Now, it’s a decommissioning site. That closure serves as a warning for the remaining plants: the economics of nuclear are incredibly fragile.
The Money Problem Nobody Likes Talking About
Nuclear power is expensive to run but cheap once it’s moving. Does that make sense? The fuel is a tiny fraction of the cost, but the security, the specialized engineering, and the regulatory compliance are astronomical.

A few years ago, PSEG basically told the state that if they didn't get financial help, they might have to shut Salem and Hope Creek down. They argued that because they weren't getting "credit" for being carbon-free—unlike wind or solar—they couldn't compete with cheap natural gas.
This led to the Zero Emission Certificate (ZEC) program.
Basically, NJ ratepayers (that's you and me) pay a small fee on their electric bills to subsidize these plants. It amounts to about $300 million a year. Critics called it a corporate bailout. Supporters, including Governor Phil Murphy’s administration, argued that losing the plants would mean replacing them with gas-fired plants, which would send the state’s carbon emissions skyrocketing. Honestly, they’re both kind of right. It is a subsidy, but it’s also the only way the state meets its climate goals right now.
Safety, Spent Fuel, and the "What If" Factor
Safety is the elephant in the room. New Jersey is the most densely populated state in the country. If something goes wrong at a nuclear power plant in NJ, there isn't exactly a lot of empty space to run to.
The NRC (Nuclear Regulatory Commission) keeps a very tight leash on these sites. They have on-site inspectors who are there 24/7. But the real issue today isn't a meltdown; it's the waste.
Since the federal government still hasn't opened a permanent repository (RIP Yucca Mountain), all the spent nuclear fuel stays on-site. It sits in "dry casks"—massive concrete and steel containers. They’re safe, supposedly for decades, but they weren't meant to be a permanent solution. Every year that passes without a national waste plan, Artificial Island becomes a de facto long-term nuclear waste dump. People in Lower Alloways Creek are understandably a bit twitchy about that.
The Rise of SMRs
There’s a new kid on the block: Small Modular Reactors (SMRs).
Holtec International, which is headquartered in Camden, is pushing hard to build these smaller, safer reactors. They want to put them at the old Oyster Creek site or even near the existing plants in South Jersey. The idea is that they are easier to build, impossible to melt down because of passive cooling, and can be scaled up as needed.
It sounds great on paper. Whether they can get the licensing and the funding to actually pour concrete is another story entirely. If NJ wants to stay nuclear, SMRs are likely the only way forward once Salem and Hope Creek eventually reach the end of their lifespans in the 2030s and 2040s.

Real World Impact: Your Electric Bill
You've probably noticed your PSE&G or Atlantic City Electric bill creeping up. It’s a mix of things—transmission upgrades, storm hardening, and yes, those nuclear subsidies. But here is the nuance: if the nuclear plants closed, the price of electricity in the PJM market (the regional grid NJ belongs to) would likely spike because we'd be importing more expensive power from out of state.
Nuclear provides "baseload" power. It’s always on. Solar is great until it rains. Wind is great until it doesn't blow. Nuclear is the "boring" energy that keeps the hospitals running at 3:00 AM on a Tuesday.
Environmental Trade-offs
Environmentalists are split. Groups like the Sierra Club have historically been anti-nuclear because of the waste and the risk. But newer climate-focused groups are starting to flip. They realize that you cannot mathematically reach net-zero carbon emissions in New Jersey without nuclear.
The math just doesn't work. You’d have to cover half the state in solar panels to match the output of the Artificial Island plants.
Then there’s the water. These plants use millions of gallons of water for cooling. Even with modern systems, it impacts local aquatic life in the Delaware River. It’s a constant tug-of-war between "carbon-free air" and "healthy local waterways."

What’s Next for Jersey’s Atoms?
The state recently cleared the way for a second round of ZEC subsidies. This ensures the plants stay open for at least another few years.
Meanwhile, the decommissioning of Oyster Creek continues. It’s a slow, meticulous process that will take decades. You can't just knock down a reactor with a wrecking ball and call it a day.
If you live in NJ, keep an eye on the BPU (Board of Public Utilities) meetings. That’s where the real decisions about your energy future are made. The transition to clean energy is messy, expensive, and full of compromises. Nuclear is the biggest compromise of them all.
Actionable Steps for NJ Residents
- Check your bill: Look for the "Societal Benefits Charge." That’s where your contribution to clean energy and nuclear stability lives. Understanding your bill is the first step to being an informed voter.
- Monitor the NRC Public Meetings: The NRC holds annual assessments for Salem and Hope Creek. They are open to the public. If you have concerns about safety or waste, that is the place to voice them.
- Look into Community Solar: If you’re worried about the cost of the grid, New Jersey has a massive community solar program. It allows you to benefit from solar power without putting panels on your roof, which can offset some of the rising costs of traditional baseload power.
- Stay updated on SMRs: Keep an eye on Holtec’s progress in Camden. If SMRs get the green light, it will change the real estate and energy landscape of South Jersey significantly over the next ten years.
- Prepare for the 2030s: The current licenses for the Salem units expire in 2036 and 2040. That seems far away, but in the energy world, that’s tomorrow. The debate over whether to extend them again or replace them will start sooner than you think.
Nuclear energy in New Jersey isn't just about science; it's about the intersection of your wallet, the environment, and the reality of keeping the lights on in a state that never sleeps.
