The core story is largely unchanged, but the updated version adds a clearer accounting of emissions composition and slightly tightens the framing around Microsoft’s resource pressures. It also broadens the operational context by explicitly linking the buildout to electricity, water, land, construction, and utility-pricing scrutiny.

The story has broadened from a Wisconsin campus buildout to Microsoft’s wider AI infrastructure push, centered on newly reported 2025 emissions growth and the company’s shift in how it sources clean power. The Mount Pleasant project remains part of the story, but it now sits alongside new power arrangements and environmental pressure across multiple states.

• Microsoft reported 20 million metric tons of greenhouse gas emissions in 2025.
• Emissions rose 25 percent year over year, mainly from construction and accounting changes.
• Microsoft stopped buying unbundled renewable energy certificates.
• Proposed West Texas and West Virginia facilities may use onsite or off-grid gas generation.
• Fairwater in Mount Pleasant became operational ahead of schedule.

The story has broadened from a single operational milestone to a much larger campus-scale and regulatory picture. Microsoft is now described as planning a far larger Mount Pleasant buildout, backed by higher committed spending and approved utility-rate structures, while state-level scrutiny of power demand becomes more explicit.

• Campus could eventually include up to 15 additional facilities.
• More than $7.3 billion committed to Mount Pleasant data centers.
• About 375 Wisconsin hires reported so far.
• Regulators approved data-center-specific electric rates.
• We Energies and Alliant Energy are now part of the utility discussion.

Microsoft has completed its first datacenter facility in Mount Pleasant, Wisconsin and begun full operations after a two-year buildout. The project is part of a larger Wisconsin expansion tied to AI infrastructure, with a second nearby facility under construction and additional hiring, local purchasing, and utility impacts shaping the broader rollout.
