Scaling Data Center Energy
The AI Manhattan Project
AI data centers are the power plants of the digital era. Training and inference at global scale requires facilities that consume gigawatts of electricity, integrate on-site renewables and storage, and operate with unprecedented efficiency. The scale and urgency have drawn comparisons to past national mobilizations — a modern “AI Manhattan Project” where the mission is not weapons or spaceflight, but building out AI compute capacity measured in exaflops and TWh.
Why Energy Defines the Build-Out
- Explosive Demand: AI workloads are projected to consume 5–10% of global electricity by 2030.
- High Density: Individual AI campuses require 500 MW+ of capacity, rivaling heavy industry.
- Thermal Load: Cooling systems must handle rack densities of 50–100 kW and beyond.
- Grid Stress: Local utilities struggle to deliver the scale and reliability hyperscalers require.
- Solution Path: Grid-tie, DER, microgrids, CHP, nuclear, and waste heat reuse must be integrated.
Build-Out Characteristics
| Dimension | 2025 State | 2030 Outlook |
|---|---|---|
| Compute | Exaflop-scale clusters in single campuses | Multi-exaflop, global “AI factories” |
| Power | 100–500 MW AI data centers | 1+ GW regional campuses |
| Cooling | Liquid cooling, rear-door exchangers | Direct-to-chip, immersion, hybrid reuse |
| Energy Source | Grid + renewables, some on-site DER | Fully integrated microgrids, nuclear pilots |
| Siting | Near metros with utility tie-in | Energy-first siting near generation hubs |
| Sustainability | PUE ~1.2, selective carbon offsets | PUE ~1.05, scope 1–3 net zero, waste heat reuse |
Key Challenges
- Grid Interconnection: Queue times of 5–10 years threaten AI DC timelines.
- Energy Autonomy: Hyperscalers must invest in on-site DER, storage, and microgrids.
- Cooling Innovation: Liquid immersion, hybrid cooling, and thermal storage are essential.
- Siting Competition: AI campuses compete with fabs, EV gigafactories, and heavy industry.
- Geopolitics: Energy supply chains (LNG, uranium, solar, batteries) are national security issues.
Giga-Scale AI Data Center Projects
Several of the largest data center projects in history are now in planning or under development. These sites highlight the unprecedented energy demands of the AI build-out - they aren’t just data centers, they’re gigawatt-scale infrastructure builds.

Case Study: Fermi America HyperGrid (Texas)
The Fermi America HyperGrid AI Data Center Complex, under development near Amarillo, Texas, is one of the most ambitious energy–AI integration projects in the world. Backed by Fermi America (co-founded by former U.S. Energy Secretary Rick Perry) and Texas Tech University, the HyperGrid campus is designed as an 11 GW private energy grid directly coupled with up to 18 million sq ft of AI data center space.
| Attribute | Details |
|---|---|
| Location | ~5,800 acres near Amarillo, Texas |
| Energy Scale | Up to 11 GW (gas, solar, batteries, + four Westinghouse AP1000 reactors) |
| Phase 1 | 1 GW online by 2026 (gas + solar) |
| AI Capacity | 18 million sq ft of AI compute infrastructure planned |
| Partners | Texas Tech University, Hyundai E&C, Doosan Enerbility, Westinghouse |
| Status | Land secured, NRC licensing for AP1000 reactors submitted; target phased rollout 2026–2032 |
Why it matters: HyperGrid represents an energy-first model of AI infrastructure — a self-contained, nuclear-anchored, gigawatt-scale campus designed to meet the explosive demands of AI compute while bypassing strained public utility grids.
Future Outlook
- Energy-First Design: AI campuses will be sited near abundant power, not just fiber hubs.
- Nuclear Integration: Small modular reactors (SMRs) piloted for AI DC energy autonomy.
- Global Build-Out: Middle East, Nordics, Texas Triangle leading in siting new AI DCs.
- Sustainability Pressure: Regulators and investors demanding transparent energy accounting.
- AI-Native Ops: Energy scheduling, cooling optimization, and carbon tracking increasingly automated by AI itself.
