The Next Phase for US Data Centres

Are you an engineer ready to shape the future of US data centres? Apply your skills to cutting-edge AI, cloud, and sustainable infrastructure projects – connect with Thor today and start making an impact.

2025 has been a landmark year for US data centres. With expansion across Virginia, Texas, Arkansas, Louisiana, and California, the country is solidifying its role as a global leader in digital infrastructure.

The demand is driven by three key factors:

AI and high-performance computing – AI workloads require enormous processing power, concentrated in GPU and TPU clusters, driving engineers to optimise power density, cooling efficiency, and redundancy systems.
Cloud adoption and digital transformation – Enterprise cloud demand is rising rapidly, requiring scalable, reliable infrastructure to host compute, storage, and networking.
Sustainability and regulatory compliance – Engineers are tasked with meeting carbon-neutral goals, LEED certifications, and energy efficiency standards.

Engineering the Backbone: Power Systems and Redundancy

Data centres are more than warehouses full of servers – they are highly engineered ecosystems. Power reliability is critical, and engineers deploy multi-layered redundancy:

UPS (Uninterruptible Power Supply) systems: Ensure continuous power during short outages.
Backup generators: Typically diesel or natural gas, sized to maintain full operational load.
Redundancy models: N+1, 2N, or 2(N+1) designs ensure no single failure causes downtime.

For AI-heavy workloads, engineers design for higher power density, often exceeding 2,000 watts per square foot, compared to traditional 150–300 W/sq ft in standard facilities. This requires careful electrical planning, including:

Large-scale switchgear and transformers,
Advanced load balancing across multiple circuits,
Real-time power monitoring and analytics.

At Thor, we place engineers who specialise in high-density power systems at the centre of these projects, ensuring every facility meets both performance and reliability standards.

Cooling and Mechanical Systems: Keeping AI Hotspots Operational

Cooling is one of the most complex engineering challenges in modern data centres. AI workloads generate extraordinary heat, and engineers must balance thermal management with energy efficiency.

Common Cooling Techniques:

Hot/cold aisle containment: Separates intake and exhaust airflows to reduce recirculation and improve cooling efficiency.
Chilled water systems and CRAC units: Distribute cooled water/air to racks.
Liquid immersion cooling: Directly submerges components in dielectric fluid – increasingly popular for high-density AI clusters.
Evaporative cooling and free-air economisers: Reduce reliance on mechanical chillers in cooler climates.

The goal is to achieve a low PUE (Power Usage Effectiveness) – ideally close to 1.1 – while maintaining stable environmental conditions. Engineers are integrating sensors, automation, and AI-driven control to optimise airflow and reduce energy waste.

Civil and Structural Engineering: Foundations for Mega-Facilities

Data centres are often enormous – up to 4 million square feet in AI-focused campuses. Civil and structural engineers face unique challenges:

Foundations and load-bearing structures: Must support hundreds of tons of equipment and raised flooring systems.
Seismic and wind considerations: Especially in Texas, California, and other high-risk areas.
Modular construction: Pre-fabricated modules speed up deployment and reduce costs.
Fire suppression systems: Gas-based or water mist systems must protect servers without damaging hardware.

These designs require engineers to collaborate across electrical, mechanical, and IT teams, ensuring systems integrate seamlessly.

Sustainability and Energy Efficiency: Engineering Responsibility

Environmental considerations are now integral to data centre design. Engineers are leading initiatives to reduce energy, water, and carbon footprints:

Renewable energy integration: Solar, wind, and hydro connections reduce grid dependency.
Energy storage systems: Batteries and thermal storage smooth peak loads.
Water management: Closed-loop cooling and rainwater harvesting reduce consumption.
Regulatory compliance: LEED certification, local permitting, and emissions reporting require careful planning and monitoring.

Projects like Fermi’s nuclear-powered data centre campus in Texas demonstrate how engineers can combine scale with sustainability, achieving massive compute capacity with minimal environmental impact.

AI-Specific Engineering Challenges

AI infrastructure pushes data centre design to new limits:

Higher computational density requires upgraded electrical distribution and cooling.
Low-latency networking for AI clusters demands precise cabling and airflow management.
Hardware turnover: GPUs and TPUs have high power draw and short lifecycle – engineers must plan for future upgrades.
Redundant systems ensure zero downtime for critical AI research and enterprise operations.

These requirements create niche engineering roles, from GPU cluster design specialists to AI-optimised HVAC engineers – roles Thor actively supports by connecting talent to the right projects.

Regional Growth Hotspots and Capacity Planning

Understanding where growth is happening is critical for engineers and recruiters alike.

Virginia: The densest cluster of data centres in the US, with strong grid infrastructure and state-level incentives.
Texas: Emerging hub for AI megaprojects, offering land availability and favourable regulations.
Arkansas & Louisiana: Seeing rapid expansion in greenfield data centres.
California: Legacy capacity continues to grow with retrofits focusing on sustainability.

Each region presents unique engineering challenges: grid constraints, water availability, environmental compliance, and climate considerations all impact design decisions.

Skills and Talent in Demand

With this rapid expansion, engineering talent is at a premium. Key roles include:

Electrical engineers: Power distribution, redundancy, UPS systems, energy monitoring.
Mechanical engineers: HVAC, liquid cooling, PUE optimisation.
Civil & structural engineers: Foundations, seismic/wind design, modular construction.
Commissioning engineers: Testing and validating complex multi-system integration.
Sustainability specialists: Renewable integration, water/energy efficiency, LEED compliance.

At Thor, we connect top-tier engineering professionals with the projects where their skills have the greatest impact. Engineers not only solve technical problems – they drive innovation across entire campuses.

Innovation in Action

Several US projects illustrate the cutting-edge engineering behind modern data centres:

Stargate AI project: Engineers designed AI-ready layouts that maximise compute density while maintaining low PUE.
Fermi Texas campus: Nuclear-powered energy reduces carbon footprint while supporting 11 GW of capacity.
Meta Louisiana facility: Advanced liquid cooling and modular design cut energy consumption by over 30% compared to traditional builds.

These examples highlight how engineering expertise transforms ambition into operational reality.

Looking Ahead: Engineering the Future of Data Infrastructure

As AI, cloud computing, and renewable energy converge, engineering innovation will remain at the heart of the US data centre boom.

From design to commissioning, engineers are building the resilient, efficient, and sustainable infrastructure that powers the digital world.
