Layer 7: Physical Infrastructure as Constellation Energy

**Constellation Energy** is the largest producer of clean energy in the United States, operating a fleet of nuclear power plants, solar facilities, and wind farms. The company has become central to the AI infrastructure story due to the enormous energy demands of AI datacenters.

In a landmark 2024 deal, Constellation agreed to restart the Three Mile Island Unit 1 nuclear reactor to supply power directly to Microsoft's AI datacenter operations. This deal highlighted how AI's insatiable appetite for reliable, carbon-free baseload power is reviving interest in nuclear energy.

Constellation Energy occupies the energy layer at the very foundation of the agentic economy. As AI inference scales to serve billions of agent interactions daily, reliable clean energy supply becomes a binding constraint — making energy providers like Constellation strategic enablers of the entire AI ecosystem.
