Island Roadhouse Data Centers has disclosed the technical design of a planned AI data center campus in Missouri that would generate its own power on site using advanced atomic reactors, cool high-density compute with closed-loop warm-water liquid cooling, and sell waste heat to third-party industrial users through a campus thermal network. The company is targeting commercial operation in 2034 for Phase 1, which is planned to offer up to 154 MW of sellable IT load.

Behind the Meter by Design

The central organizing principle of the Island Roadhouse campus is that it generates its own power on site rather than drawing from the electrical grid. The planning basis calls for advanced atomic reactors in an N+1 configuration to provide reactor-level redundancy.

Heat from those reactors is planned to be converted to electricity through an indirect closed supercritical carbon dioxide Brayton cycle.

The company has stated that no export to the grid is planned and that the campus is not intended to function as a power exporter.

The decision to build behind the meter is a direct response to conditions in the United States' power infrastructure. Lawrence Berkeley National Laboratory's "Queued Up: 2026 Edition," published in June 2026, reported that at the end of 2025 approximately 8,200 projects representing 1,312 gigawatts of generation were waiting in United States interconnection queues, and that the median time from interconnection request to commercial operation exceeded five years for projects completed in 2025.

The International Energy Agency's "Key Questions on Energy and AI," published in April 2026, projected that global data center electricity consumption would roughly double from 485 terawatt-hours in 2025 to 950 terawatt-hours in 2030, and noted that data center developers in the United States, constrained by slow grid connections, are turning to on-site generation. David Kinsman, Chief Technology Officer of Island Roadhouse Data Centers, addressed the rationale directly.

"The constraint on AI infrastructure is no longer the chip.

It is power, and the years it can take to get power delivered. We designed this campus so that the power is generated where the compute sits, behind the meter," Kinsman said.

He described the reactor systems, power conversion, liquid cooling, and heat network as engineered together as a single campus rather than as separate infrastructure layers. "Power and cooling are not two problems.

They are one system," he said.

Water Conservation as a Core Constraint

Water consumption is cited alongside power grid delays as a foundational constraint the design is meant to address. Lawrence Berkeley National Laboratory's "2024 United States Data Center Energy Usage Report," published in December 2024, estimated that United States data centers directly consumed approximately 66 billion liters of water in 2023.

Island Roadhouse has positioned its campus as a low-water design and has established an annual water-use-effectiveness planning target, though a specific numerical target was not disclosed in the announcement.

The high-density data halls are designed around closed-loop warm-water direct-to-chip liquid cooling, with dry heat rejection serving as the primary and ultimate campus heat sink.

By relying on dry heat rejection rather than evaporative cooling, the campus avoids the large water withdrawals associated with conventional cooling tower approaches. The company has not disclosed a specific water-use-effectiveness figure, but has described the low-water designation as a design goal embedded in the campus from the planning stage rather than an afterthought.

Waste Heat as a Revenue-Generating Product

One of the more distinctive elements of the Island Roadhouse design is its treatment of waste heat as a commodity to be sold rather than a problem to be disposed of.

The campus is planned to make thermal energy available to third-party industrial process users and other non-industrial users through a campus thermal network.

The planned service model involves thermal capacity reservation, metered thermal energy delivery, and thermal interconnection agreements.

Users who take heat from the network would finance, build, own, and operate their own facilities. Kinsman described the thermal design in explicitly commercial terms. "Every data center produces heat, and most of them pay to throw it away.

Our thermal design treats heat as a product.

The campus is designed to sell data center waste heat through a metered thermal network so users can take the heat we would otherwise reject," he said. The company was careful to note that heat reuse is an optimization rather than an operational dependency.

The campus is designed to reject all of its required heat on its own through dry heat rejection, meaning that if no third-party users are connected to the thermal network, the campus can still operate normally.

Thermal energy storage is planned as an optimization asset within this system. Notably, the campus has no grid-scale battery planned; the only energy storage asset described in the design is thermal storage.

Campus Business Model and Phase Structure

Island Roadhouse sells long-term, power-backed, liquid-cooling-ready data center capacity and facility services.

The company's stated business model is oriented toward customers who bring and operate their own compute equipment.

Island Roadhouse does not sell electricity, cloud compute or GPU-as-a-service as its base business. Phase 1 of the campus is planned to offer up to 154 MW of sellable IT load, with commercial operation targeted for 2034.

A Phase 2 expansion is also planned under the campus master plan, though no specific capacity figures or timeline for Phase 2 were disclosed in the announcement.

The company described itself as developing an integrated campus that combines on-site advanced atomic generation, high-density liquid-cooled data halls, dry heat rejection, and heat reuse for third-party industrial and agricultural users, and is based in Missouri.
