Microsoft Cheyenne Data Center Campus

Capacity: announced vs energized

Construction evidence

Dated satellite imagery of the site itself, oldest to newest, with the campus milestones that landed in each window. This is what the site looked like from orbit while announcements, permits, and energizations were dated into our ledger, so bare land, grading, and building mass tell their own story alongside the paper trail.

Key facts

Reported facts

Structured facts sourced from citations already on this record. Each fact traces to a source in the References section below.

~3,200-acre expansion intent (primary Microsoft)

Microsoft announced (Apr 14 2026) intent to purchase about 3,200 acres to expand datacenter operations in Cheyenne: roughly 200 acres in Bison Business Park on Wapiti Trail east of S Greeley Highway, plus about 3,000 adjacent acres in southeast Cheyenne. The company says it has operated there since its first Cheyenne datacenter in 2012 and frames the purchase as the start of a multiyear planning and development process with public hearings (Microsoft Source, Apr 14 2026)

Black Hills Energy LPCS tariff (primary Microsoft)

Microsoft states power acquisition for Cheyenne is guided by Black Hills Energy's Large Power Contract Service (LPCS) tariff, under which Microsoft directly pays for infrastructure upgrades and power procured to serve its load, with the company saying the structure is designed so datacenter development does not increase electricity prices for other customers (Microsoft Source, Apr 14 2026)

Community investment / taxes / jobs (primary Microsoft)

Microsoft says it has committed over $68 million in completed and future off-site infrastructure improvements in Cheyenne, contributed over $11 million to the Laramie County tax base in 2025 (No. 1 taxpayer in Cheyenne; No. 2 in Laramie County), employs over 320 full-time workers there, has trained over 1,000 students via a Datacenter Academy with Laramie County Community College since 2019, and has donated $4.7 million to local organizations since 2018. Water framing: existing Wyoming facilities use direct evaporative cooling less than 10% of the year, with newer designs aiming to eliminate ongoing cooling water after initial fill (Microsoft Source, Apr 14 2026)
