Powering AI Data Centers

YOUR FUTURE — OUR INFRASTRUCTURE

Building the Foundation for AI Compute

Yellowbox builds scalable, gas-secured infrastructure to meet the land, power, and cooling needs of AI data centers when the grid isn’t ready. Our projects deliver tailored solutions for hyperscalers, colocation providers, and developers, combining behind-the-meter (BTM) power, EnerCool thermal systems, and modular designs. Explore our current and planned projects to see how we’re enabling rapid, reliable, and sustainable growth.

Project Horizon

Southern Illinois

Location: Southern Illinois

Offering: 40 MW grid-connected, power-and-permit-ready site on 22 acres

Details: Purpose-built campus designed for rapid deployment of high-density compute, AI, and cloud workloads. The site includes 40 MW of confirmed grid power with an additional 10 MW of natural gas backup capacity. Positioned along a key corridor to the Chicago metro, it supports strong fiber connectivity and water availability. Backed by Enterprise Zone incentives and TIF support to reduce upfront costs.

Status: Power-ready delivery estimated in 12–18 months from PPA execution; site access immediate upon agreement. Construction can start within 30–60 days of site control, minimizing lead times and grid interconnection delays.

Outcome: Enables fast activation with reliable, scalable power, and direct access to major Midwest data and logistics hubs.

Project Lone-Star

Location: South of Dallas/Ft. Worth

Offering: 504-acre, power-secured land platform designed for hyperscale, AI, and high-performance computing (HPC)

Details: Build-to-suit and engineered to support high-density compute infrastructure with a targeted Phase 1 capacity of 300 MW, expandable up to 700 MW and beyond. The site features 100% behind-the-meter natural gas generation with dual-pipeline access, optimized for ~1.1 PUE, N+2 redundancy, and five nines (99.999%) reliability. Transmission easements run along the west side of the property, and a substation is located less than two miles away, enabling robust connectivity and future grid tie-in flexibility.

Status: Entitlement and permitting activities underway with a staged construction timeline supporting fast-track deployment.

Outcome: Enables rapid delivery of large-scale, high-reliability capacity for hyperscale and AI workloads, bypassing traditional grid bottlenecks and supporting future replication across additional sites.
