Exploring Nuclear Power: Rock City's Innovative Energy Plans (2025)

Nuclear Power in an Underground City: A Controversial Energy Solution?

Imagine a city beneath your feet, a former cave transformed into a bustling industrial hub. This is the reality of Rock City, a unique development in the village of Valmeyer. But here's where it gets controversial: the developer is considering an unconventional power source—miniature nuclear reactors. This bold idea has sparked curiosity and debate among residents and experts alike.

Rock City, once a limestone mine, now houses the National Archives and various businesses. The developer, Admiral Parkway Inc., has signed a deal with Terra Innovatum, an Italian nuclear power company, to potentially bring up to 50 mini nuclear reactors to the site. These reactors, called Solo reactors, are compact yet powerful, standing at 10 meters tall and capable of producing 1 megawatt of electricity each.

But there's a catch. The technology is awaiting approval from the Nuclear Regulatory Commission for use in the United States. The developer, Joe Koppeis, acknowledges the uncertainty: "We don't know if it will ever get approved... If it does, I would love to consider it." Terra Innovatum, despite being contacted, remains silent on the matter.

And this is the part most people miss: Rock City's quest for alternative energy is not new. Koppeis has been exploring options for years due to high electricity rates. Past ideas included wind and water power, but faced community opposition and practical challenges. Now, a gas-fired power plant is on the table, but environmental assessments are required.

The village of Valmeyer, which owns the cave, has a lease agreement with Koppeis, bringing in significant revenue. Mayor Howard Heavner remains open-minded but seeks more information. Meanwhile, construction work has drawn attention, with residents speculating about a potential data center tenant, an energy-intensive industry.

Koppeis has openly expressed interest in attracting a data center, touting the cave's natural cooling advantages. However, he assures that recent energy explorations are unrelated to data center plans. The Illinois Department of Natural Resources is reviewing the environmental impact of potential groundwater removal, adding another layer of complexity to this intriguing story.

This innovative yet controversial energy solution raises questions: Will the Solo reactors be approved? Can Rock City find a sustainable power source? And what impact will future tenants have on this underground city? The answers remain to be seen, leaving room for lively discussion and anticipation of what's to come.
