NBIS Independence MO Data Center

Nebius's Independence project is a purpose-built campus planned for up to 1.2 GW across roughly 400 acres near Route 78 and Little Blue Parkway. Construction has begun, but the full development remains a multi-year undertaking. Its scale should be understood through the sequence of buildings and power delivery, rather than counted as current computing capacity.

It is also separate from Patmos's smaller retrofit at 2500 South Little Blue Parkway. Patmos explicitly says Nebius has no involvement in that Independence project. The shared city name and the companies' existing Kansas City relationship are not grounds for combining the properties. Patmos's project clarification.

Groundbreaking and the current building plan

Nebius announced groundbreaking on May 12, 2026. Its community disclosure now describes four buildings constructed over five to seven years, with ARCO as the general contractor for Phase 1. This replaces the older study's ten-building description and shorter generalized construction horizon. Nebius groundbreaking announcement. Current Independence project disclosure.

An owned campus gives Nebius control over the building sequence and systems design. It also leaves the company responsible for coordinating construction and equipment deployment. Large land ownership does not make utility work, permits or hardware commissioning disappear.

The 1.2 GW plan has two power components

The current disclosure describes 800 MW through Independence Power & Light and 400 MW of future on-site generation. It links the utility component to a new privately financed project at the retired Blue Valley plant site, with energy entering the Southwest Power Pool and Nebius buying from the grid. The on-site solution remains under evaluation.

These are different physical and commercial pathways. The 800 MW is not a statement that all of it is already energized, and the 400 MW is not a completed generating plant. Nor should the full 1.2 GW be described as an isolated power system independent of the grid.

Initial utility delivery is targeted for the second half of 2026, while later supply and construction extend into subsequent years. Each phase needs its own evidence of energization and customer readiness. A campus can receive initial power well before its ultimate capacity becomes available.

Cooling, backup and community commitments

Nebius describes closed-loop cooling and backup generators intended to support safe shutdown. That is a different claim from providing indefinite full-load operation through an outage. The final backup design and service obligations will determine the operational consequences of a power interruption.

The company's sound analysis models the proposed equipment and mitigation measures. Modelled compliance is a design input; measured operating noise will become a separate observation once equipment runs. The same distinction applies to projected water use and the later performance of the cooling system.

The investment question follows the delivery sequence

The older claim that $6.6 billion represented land and site preparation alone is withdrawn. The reviewed company material describes a multi-billion-dollar campus investment without supporting that narrow cost allocation.

For future analysis, the sequence is practical: confirmed utility delivery, completed hall, commissioned systems, installed computing equipment and customer acceptance. A larger ultimate envelope creates room for growth, while each achieved stage determines how much of that room can support customers.

The existing Kansas City deployment provides the regional operating context. The Nebius company page contains the wider business research and dated forecasts. This factual study was reviewed through September 17, 2026.
