The convergence of clean energy and cryptocurrency mining is gaining momentum, with TeraWulf leading the charge through its state-of-the-art Nautilus bitcoin mining facility near Berwick, Pennsylvania. This cutting-edge operation marks a pivotal moment in the evolution of sustainable crypto mining, leveraging nuclear power to fuel high-efficiency bitcoin production while minimizing environmental impact.
The Nautilus Facility: A Model for Sustainable Mining
At the heart of this initiative is the Nautilus bitcoin mining facility, a 50 MW data center currently undergoing full deployment of advanced mining hardware. TeraWulf, the company behind the project, has begun active mining operations and aims to bring its entire Phase One capacity—delivering 1.9 exahashes per second (EH/s)—online by May 2025.
What sets Nautilus apart is its direct energy integration with the 2.5 gigawatt Susquehanna nuclear power plant, one of the largest and most reliable zero-carbon energy sources in the United States. The plant, primarily owned and operated by Talen Energy, sits adjacent to the mining site—a strategic co-location made possible by a landmark agreement between TeraWulf and Talen Energy established in 2021.
This proximity allows Nautilus to draw power directly from a stable, emissions-free source, setting a new benchmark for environmentally responsible blockchain infrastructure.

Scalable Infrastructure with Zero-Carbon Vision
TeraWulf’s vision extends beyond initial deployment. The company holds an option to expand Nautilus by an additional 50 MW, potentially doubling the site’s total capacity to 100 MW. This phased growth strategy ensures flexibility and scalability as market conditions evolve and more efficient mining hardware becomes available.
With both phases operational, Nautilus could become one of the most powerful and sustainable bitcoin mining hubs in North America—powered entirely by clean energy.
TeraWulf operates two primary mining sites: Nautilus in Pennsylvania and another facility in New York. Together, these installations are already powered by 91% zero-carbon energy, combining nuclear, hydroelectric, and solar sources. The company has set an ambitious long-term goal: achieving 100% renewable and emission-free energy across all operations.
High-Efficiency Mining Hardware Deployment
To maximize performance and sustainability, TeraWulf is deploying a carefully selected mix of Bitmain ASIC miners, known for their reliability and energy efficiency in large-scale operations.
The core of the current deployment includes:
- Bitmain S19 XP Pro: Delivering 140 terahashes per second (TH/s) with a power draw of approximately 3 kW, this model achieves an impressive efficiency rate of 21.5 joules per terahash (J/TH).
- Bitmain S19j Pro and S19 Pro: Operating at 100 TH/s with similar power consumption (~3 kW), these models offer slightly lower efficiency at 30 J/TH, but remain highly competitive in real-world conditions.
By combining top-tier hardware with ultra-low-carbon power, TeraWulf not only enhances profitability but also strengthens the environmental case for institutional participation in bitcoin mining.
Why Nuclear Power Makes Sense for Bitcoin Mining
Bitcoin mining has long faced criticism over energy consumption. However, the Nautilus facility demonstrates that when powered by nuclear energy, mining can be both scalable and sustainable.
Nuclear power offers several key advantages:
- 24/7 baseload power: Unlike solar or wind, nuclear plants operate continuously, providing uninterrupted energy critical for stable mining operations.
- Zero greenhouse gas emissions: Nuclear generates electricity without emitting carbon dioxide or air pollutants during operation.
- High energy density: A small physical footprint produces massive amounts of power—ideal for energy-intensive applications like crypto mining.
By tapping into the Susquehanna plant’s excess capacity, TeraWulf turns underutilized clean energy into economic value, effectively monetizing low-cost, carbon-free electricity without increasing grid demand or environmental strain.

Environmental Impact and Industry Leadership
TeraWulf’s commitment to sustainability goes beyond marketing claims. With 91% of its current energy mix coming from nuclear, hydro, and solar sources, the company is among the leaders in green crypto mining.
The use of nuclear power at Nautilus significantly reduces the carbon footprint associated with bitcoin production. In fact, studies suggest that bitcoin mined using nuclear energy emits less than 50 grams of CO₂ per dollar of value created—comparable to or better than many traditional financial transactions.
As global regulators increase scrutiny on digital asset sustainability, TeraWulf’s model positions it well for compliance and long-term resilience.
Frequently Asked Questions (FAQ)
Q: Is nuclear-powered bitcoin mining safe?
Yes. The Nautilus facility does not house any radioactive materials or reactors. It simply consumes electricity generated by the nearby Susquehanna nuclear plant, operating under standard industrial safety protocols.
Q: How does nuclear energy make bitcoin mining more sustainable?
Nuclear power produces large amounts of electricity without burning fossil fuels. When used for mining, it eliminates the carbon emissions typically associated with coal or natural gas-powered grids.
Q: Can other miners replicate this model?
Absolutely. While access to nuclear plants requires special agreements, many regions have underutilized clean energy sources. Co-locating miners near such facilities—nuclear, hydro, or geothermal—can replicate this sustainable model elsewhere.
Q: What is TeraWulf’s long-term goal?
TeraWulf aims to achieve 100% zero-carbon energy across all its operations while expanding its total mining capacity through strategic site development and technological upgrades.
Q: Why is energy efficiency measured in J/TH?
Joules per terahash (J/TH) measures how much energy a miner uses to perform one trillion hash calculations. Lower numbers mean higher efficiency—critical for profitability and sustainability.
Q: Does this reduce electricity costs for consumers?
Not directly. However, by utilizing off-peak or excess generation capacity, projects like Nautilus help stabilize grid economics and support continued investment in clean energy infrastructure.

The Future of Clean Crypto Mining
The success of the Nautilus facility could inspire a wave of similar projects across the U.S. and globally. As concerns about climate change grow, pairing bitcoin mining with nuclear and other zero-carbon energy sources presents a viable path forward—one that aligns financial incentives with environmental responsibility.
With Phase One nearing completion and expansion plans in motion, TeraWulf is proving that sustainable bitcoin mining isn’t just possible—it’s profitable.
As the industry evolves, expect more miners to follow suit, seeking partnerships with clean energy providers and adopting next-generation hardware to build a greener digital economy.
