IREN is constructing its “Horizon 1” data center as a new 75-megawatt (MW) facility at Childress, Texas. Advanced liquid cooling technology powers this facility as it supports both AI and HPC tasks. The facility targets the future NVIDIA Blackwell GPUs through its specialized cooling system that works with dense hardware requirements. Iwen-Chen Research Center plans to finish this AI computing resource project during the second half of 2025 to address growing market needs. Amadeus has designed Horizon 1 to use direct-to-chip liquid cooling, which will enable efficient heat management during powerful computing operations. The new cooling technique enhances operational results while decreasing power usage better than typical cooling techniques do. The data center operates as a multi-tenant facility since it enables several clients to use its services concurrently while providing adaptable, scalable computing options to businesses operating with advanced requirements.
$1 Billion Funding for Expansion
The $1 billion at-the-market facility created by IREN supports its expansion initiatives. Through this financial strategy, IREN can generate the capital needed at any time by directly selling company shares in the secondary trading market. The funds obtained from the ATM facility will support IREN’s corporate initiatives by enabling data center expansion programs as well as the implementation of advanced liquid cooling systems technology. The obtained funds will boost IREN’s computing ability to 57 exahashes per second (EH/s) by the second half of 2025, beyond its original target of 50 EH/s. IREN plans to finish up the final stage of construction at the Childress data center while extending its total electricity capacity to 750 megawatts by 2025 through this development. The company anticipates that these new projects will raise IREN’s operational performance while boosting its profitability.
Development of a 2GW Data Center in Sweetwater
IREN continues to progress its construction of the Sweetwater 2 data center hub situated in Texas at two sites. IREN plans to develop two distinct data center facilities: Sweetwater 1, with a 1.4 GW capacity set to energize by April 2026, and Sweetwater 2, with a 600 MW capacity expected for service by 2028. A data center hub totaling 2GW will emerge from the combined power generation of these sites. The Sweetwater 2 facility currently possesses 500 acres of land while finalizing its 600MW power connection to the electricity grid. Work on design is currently ongoing to establish a straight fiber cable system between Sweetwater 1 and 2, which will make the facilities more connected and efficient. IREN builds the capacity to handle rising data processing and storage solution needs through its recent developments.
Advancements in Liquid Cooling Technology
The existing data centers at IREN will receive distributed liquid cooling systems installed directly on their processing components. Low-temperature liquid circulates directly to heat-emitting components, such as the processor, to maximize their heat dissipation functions. By using the direct-to-chip liquid cooling system, IREN can reach higher performance levels and cut down energy consumption better than conventional air-cooling methods.IREN chose liquid cooling as part of its business strategy for supporting fast cloud and colocation service expansion. Through this technology upgrade, IREN seeks to welcome clients with demanding high-density computing requirements by providing them with reliable, efficient infrastructure.
Strategic Partnerships and National Security Implications
IREN’s strategic expansion follows current industry patterns that incorporate technological collaborations with major companies together with security aspects when building AI infrastructure. IREN uses its investments in big and sophisticated data centers to make itself a leading provider of essential digital structures needed for both economic expansion and national defense.
The business strategies create benefits for IREN’s market leadership position and develop vital infrastructure. IREN develops smart data-handling infrastructure through its large facility investments using advanced technology for growing storage requirements, which help both business and national security requirements. IREN demonstrates its commitment to data center expansion through its initiatives, which support rising requirements for AI and HPC workload needs.
