The single biggest constraint on the AI buildout: getting enough electricity to the right place.
| Category | Power/Rack | Notes |
|---|---|---|
| Traditional | 5-10 kW | Still most common for general purpose |
| AI-capable | 30-100+ kW | Averaging 60+ kW in dedicated AI facilities |
| NVIDIA GB200 NVL72 | 132 kW peak | Requires liquid cooling |
| Future (Blackwell Ultra/Rubin) | Up to 900 kW | 576 GPUs per rack |
| NVIDIA's OCP 2025 preview | Up to 1 MW | Requires 800 VDC power distribution |
Industry average: ~1.5 (50% overhead for cooling/infrastructure). Best-in-class hyperscale: below 1.1. Silicon Carbide (SiC) UPS systems achieve up to 99% efficiency in eco-mode.
Primary source, but interconnection queues and substation capacity are the binding constraint. Average queue time: ~5 years (up from <2 years in 2008). Over 8.9 GW across 105 projects targeting operation by end 2026.
| Company | Partners | Capacity | Timeline |
|---|---|---|---|
| Oklo | Switch, Meta, Equinix | 500MW+ committed | First systems 2027; commercial 2030 |
| NuScale | ENTRA1 Energy, TVA | 6 GW deployment program | Late 2020s |
| TerraPower | Natrium reactor | 345 MW | 2028-2030+ (fuel delays) |
| Kairos Power | Google (500 MW) | NRC-approved Hermes test reactor | Test reactor 2027 |
Trump signed four Executive Orders in May 2025 to speed SMR deployment. Major commitments: Amazon/Dominion/X-energy 5 GW; Microsoft exploring Three Mile Island restart; Meta 4 GW.
2025 is the year liquid cooling tipped from bleeding-edge to baseline. Common design: 70% liquid / 30% air. Liquid cooling is up to 3,000x more efficient than air.
Fastest-growing segment. Cold plates attached directly to processors. Preserves standard server form factor. Preferred by most hyperscalers for current GPU deployments.
Full immersion in dielectric fluid. Requires component changes. Key players: Iceotope (rack-compatible), Vertiv, GRC (partnered with LG/SK Enmove).
Schneider Electric promotes as upgrade path for legacy DCs. Captures heat from server exhaust before it enters the room.
| Company | Focus | Recent Activity |
|---|---|---|
| Vertiv | Full portfolio | 60% YoY increase in organic orders (Q3 2025) |
| Schneider Electric | CDUs, RDHx, cold plates | Acquired Motivair (Feb 2025). NVIDIA reference designs for GB300 NVL72 |
| CoolIT Systems | D2C cooling | Major vendor for hyperscale deployments |
| GRC | Immersion | Partnered with LG/SK Enmove |
| Iceotope | Rack-compatible immersion | Innovative form factor |
Hyperscalers deploying medium voltage distribution up to 13.8 kV and DC voltage architectures at 400 VDC and 800 VDC. Schneider Electric: "The 1 MW AI IT rack is coming and it needs 800 VDC power."
Grid access, not land, is the primary bottleneck. Demand-side interconnection queues contain hundreds of GW of DC projects in the US alone.
The industry has shifted from connectivity-first to power-first site selection. AI introduces power-availability zones optimized for scale compute.
| Market | Inventory (MW) | Status |
|---|---|---|
| Northern Virginia | 4,039 MW | Delivered >1 GW new in 2025. Power-constrained but still dominant |
| Dallas-Fort Worth | Doubling by 2026 | 89% of under-construction is preleased |
| Phoenix | Major expansion | Abundant land and solar |
| Chicago, Atlanta, Portland/OR | Established | Continuing growth |
Fervo Energy Cape Station (Utah): first commercial-scale EGS. First 100 MW phase expected to deliver first power in 2026, with 400 MW more by 2028.
Google signed a 200 MW PPA with Commonwealth Fusion Systems. Planned 400 MW from inaugural ARC plant, projected first power to Virginia grid in early 2030s. This is the first major commercial fusion PPA for data centers.
Google's $4.75B Intersect acquisition includes advanced geothermal, LDES, and gas with CCS. Multiple DC companies signed LDES deals in 2025.
| Type | Region | Price ($/MWh) |
|---|---|---|
| Solar PPA | ERCOT (Texas) | $35-45 |
| Solar PPA | US national avg | $52-58 |
| Solar PPA | CAISO (California) | $70-85 |
| Wind PPA | Nordics | <$30 |
Overall renewable PPA prices up 9% in 2025, continuing to rise with demand.
Faster path to power (12-18 months vs 5+ years for grid) but at higher $/MWh and with emissions tradeoffs. Power is the single largest ongoing operating expense. See Economics & Financing for full cost analysis.
