Microsoft

Microsoft's AI infrastructure thesis is built around vertical integration: own the campus, own the chips, own the model. Mount Pleasant WI, Three Mile Island nuclear restart, the Crane Clean Energy Center 20-year PPA — all hand-picked to give OpenAI workloads dedicated, decarbonized base-load that's not exposed to grid queue uncertainty.

What sets Microsoft apart is execution speed plus deal originality. The Constellation TMI restart was the first-of-its-kind nuclear PPA for AI; the entire industry has copied the template since. Watch the Crane PPA cost-per-MWh structure — it's becoming the benchmark every hyperscaler nuclear deal references.
