A proposed data center complex in northern Utah has sparked sharp debate. At full scale the Stratos project could draw 9 gigawatts of electricity. That exceeds the current average demand of the entire state. And the associated waste heat has one physicist drawing an explosive comparison.
Dr. Rob Davies, a physics professor at Utah State University, examined the plans. He concluded the combined output from the servers and a dedicated natural gas power plant would release energy equivalent to 23 Hiroshima-scale atomic bombs each day. The figure landed like a shock in Hansel Valley. Local residents already uneasy about the scale grew more alarmed.
The numbers come from basic physics. The facility would consume 9 GW. Its 55 percent efficient gas plant would throw off another 7 to 8 GW of waste heat. Total thermal load reaches roughly 16 GW. Spread over 24 hours the release differs from a bomb’s instant blast. Still, the steady addition of that energy into a closed desert basin carries consequences. Davies published a preliminary analysis.
Temperatures could climb 2°F to 5°F during the day across the valley. At night the rise might hit 8°F to 12°F. Nighttime warming matters here. It disrupts the natural condensation cycle that delivers moisture to fragile desert plants and soils. The valley sits within the Great Salt Lake watershed. That system already struggles with drought, shrinking water levels and dust problems.
“The thermal load from the proposed Stratos project is extreme,” Davies said. “There is no way around the physics. This is the energy output of two-and-half New York City’s poured into a single confined desert basin, in a watershed that’s already in crisis. Of course it has effects. One of those effects is this: This facility imposes substantial drying on a watershed and ecosystem already in active collapse.” (Grow the Flow Utah, May 7, 2026)
His analysis compares the heat output to the daily energy footprint of 40,000 Walmart Supercenters. The project itself would cover about 40,000 acres. That’s three times the size of Manhattan. Backers envision it as one of the world’s largest campuses dedicated to artificial intelligence workloads, cloud computing and national security applications. Celebrity investor Kevin O’Leary has promoted the effort on national television. He argues it will create thousands of jobs and help the United States outpace China in the race for compute power.
But the approval process hit turbulence. The Box Elder County Commission delayed its vote after hearing resident concerns. On May 4 it approved creation of the Stratos Project Area anyway. The Military Installation Development Authority, a state agency, oversees the site. It straddles military interests, local government and private developers. Much of the land is privately owned and unincorporated. All landowners consented, project supporters note.
Power would come from a connection to the Ruby Pipeline, which carries natural gas from Wyoming through Utah toward western markets. The plant would generate electricity on site. Dry cooling systems using massive banks of fans would handle server and plant heat rejection. Those fans themselves consume power and add noise. They also push the thermal burden directly into the air rather than dissipating some through evaporation.
Critics point to broader patterns. A University of Cambridge study found data centers can form heat islands that raise nearby temperatures by several degrees as far as 10 kilometers away. Omdia Senior Research Director Vlad Galabov pushed back on alarm. “Simple physics suggests that even very large datacenters contribute only a small additional heat flux when spread over kilometres,” he told The Register.
Yet Davies stands by the local effect. Hansel Valley acts like a bowl. Temperature inversions trap heat at night. The added load would compound existing stresses near the receding Great Salt Lake. Ecologist Ben Abbott, executive director of Grow the Flow and a professor at Brigham Young University, called for deeper study. “If there is any chance these calculations are correct, it would impact farms, wildlands, and Great Salt Lakes in serious ways,” Abbott said. “We need access to the full details of the facility and time to analyze the potential impacts before going forward.” (Grow the Flow Utah)
Financial questions loom just as large. Building 1 GW of AI-focused data center capacity can cost between $35 billion and $60 billion according to various estimates. For a 9 GW project the total could exceed $300 billion when factoring in power generation, construction and IT equipment. Omdia principal analyst Alan Howard offered a more measured view. He pegged building construction, power and cooling at roughly $8 billion for that scale. Add generation and servers and the figure climbs above $100 billion.
“What’s important here is that the money comes from different sources,” Howard explained. “Stratos pays for site development; other companies will likely pay for building construction; even other companies will build and operate the onsite power generation; and even other companies will buy and operate the IT equipment. The tricky part is the tepid climate for funding these big projects. While there will be multiple companies providing funding for different pieces, the debt financing underwriting process will look at the broader project as part of their risk assessment.” (The Register)
Banks have started to notice. The Financial Times reported that JPMorgan Chase and Morgan Stanley are seeking ways to spread data center loan risks across more investors. Construction expenses have surged. Land, specialized cooling, substations and backup systems drive costs far higher than past projects. CoStar Group documented the trend in a recent analysis.
The project rollout would stretch over years. Full 9 GW capacity might not arrive for a decade, if it arrives at all. Early phases call for about 3 GW. That alone would nearly match Utah’s current statewide average consumption of roughly 4 GW. State leaders have pushed “Operation Gigawatt” to expand generation, including nuclear and geothermal options. Yet most new data center demand in Utah has turned to natural gas so far.
Opposition has grown beyond environmental calculations. Some residents worry about noise, traffic, water draw in a drought-prone region and the industrialization of rural land. Petitions circulated. Accusations flew. O’Leary has claimed certain opposition groups receive Chinese funding, a charge they reject. The Guardian described the approval as drawing “backlash” and quoted Davies again on the extreme thermal load. (The Guardian, May 13, 2026)
Analysts debate whether the project will reach its advertised size. Meta plans a 5 GW Hyperion cluster elsewhere. The first 1 GW single facilities are only now expected to come online. Stratos would dwarf them. But securing tenants, power contracts, environmental permits and continuous financing at this magnitude presents a steep challenge. Not every announced hyperscale project reaches full build.
Still the underlying pressure continues. Artificial intelligence training and inference devour electricity. Every major technology company hunts for gigawatts of reliable power. Western states including Utah have seen data center demand grow faster than supply. A February report in The Salt Lake Tribune noted that new facilities may eventually consume quadruple current state usage. Many are building their own generation, often gas-fired.
Davies never claimed his work was peer-reviewed or final. He called it preliminary and urged independent ecological assessment. Skeptics on forums questioned the bomb analogy because a nuclear detonation releases energy in nanoseconds while the data center spreads it across a full day. Andy Masley, a writer who has taught high school physics, reviewed the math and found the core energy accounting holds when using the Hiroshima bomb as reference.
The discussion reveals a larger tension. Society wants the benefits of advanced computing. It also wants stable climates, healthy ecosystems and affordable power for homes and businesses. Concentrating 16 GW of thermal energy in one high-desert basin tests that balance. Supporters see Stratos as strategic infrastructure for national competitiveness. Opponents see an experiment with unpredictable local costs.
Construction has not started. Detailed engineering studies, full environmental reviews and firm tenant commitments remain ahead. The debate however has already sharpened focus on the physical realities behind the AI boom. Heat is not abstract. In Hansel Valley it could reshape temperatures, moisture patterns and biological communities for decades. Whether the project proceeds at advertised scale will depend on how regulators, financiers and future tenants weigh those trade-offs against the promised economic and technological gains.
Recent coverage shows the controversy has not faded. On May 12 the Deseret News examined the role of Utah House Speaker Mike Schultz and other officials who met with O’Leary last year. The article also noted developers have committed about $20 million so far while total costs could top $100 billion. (Deseret News, May 12, 2026)
Fortune magazine highlighted resident revolts and compared the Utah plan to O’Leary’s separate $70 billion Wonder Valley project in Alberta, Canada. Both aim at massive AI compute. Both face questions about feasibility and local impact. (Fortune, May 11, 2026)
