# AI compute demand is creating a terrestrial power crisis with 140 GW of new data center load against grid infrastructure already projected to fall 6 GW short by 2027

The energy crisis for AI compute is not hypothetical -- it is the binding constraint on industry growth right now. US data center power consumption is currently under 15 GW, but the pipeline of facilities under construction will add approximately 140 GW of new load. PJM Interconnection, which operates the largest wholesale electricity market in the US covering 13 states, projects it will be six gigawatts short of reliability requirements by 2027. Power constraints are extending data center construction timelines by 24 to 72 months. In a 2025 industry survey, 72 percent of respondents identified power and grid capacity as their biggest constraint on expansion.

This creates genuine structural demand for alternative compute locations -- anywhere that power is abundant and grid interconnection queues do not apply. The demand-side argument for orbital data centers, arctic data centers, nuclear-powered facilities, and on-site generation all rest on this same foundation. The current bidding war among Amazon, Google, Microsoft, and Meta for nuclear power agreements, co-location with natural gas plants, and exploration of orbital compute all reflect the same underlying pressure: AI's appetite for electricity is outpacing the grid's ability to deliver it.

The implications extend beyond data centers. Grid strain from AI compute competes with electrification of transport, heating, and manufacturing for the same finite transmission infrastructure. Every megawatt devoted to training the next frontier model is a megawatt unavailable for other economic activity.

## Evidence
- US data center power: <15 GW current, 140 GW pipeline
- PJM Interconnection: 6 GW reliability shortfall projected by 2027
- 72% of industry survey respondents cite power as top constraint
- Amazon, Google, Microsoft, Meta all pursuing nuclear power agreements (2024)

## Challenges
Demand projections may overshoot if AI efficiency improvements (quantization, distillation, smaller models) reduce per-inference power consumption faster than demand grows.

Hyperscaler response to power crisis is not waiting for grid expansion but directly contracting nuclear capacity: Microsoft $16B Three Mile Island PPA, Amazon 960 MW Susquehanna PPA, Meta Clinton Power Station agreement, Google $4.75B Intersect Power acquisition. These deals bypass utility markets entirely through behind-the-meter architecture and direct PPAs.


Relevant Notes:
- [[space-based computing at datacenter scale is blocked by thermal physics because radiative cooling in vacuum requires surface areas that grow faster than compute density]] — the physics case against the orbital solution
- [[arctic and nuclear-powered data centers solve the same power and cooling constraints as orbital compute without launch costs radiation or bandwidth limitations]] — terrestrial alternatives that address the same crisis
