Three major hyperscaler capacity adds totaling 346 MW announced same week; Cheyenne, WY holds 69.5 excess-power score as Dublin, OH constraint hits 72.5
## Highlights
KKR completed a **$10 billion** infrastructure transaction with Nvidia on June 12, marking one of the largest single-company data center deals recorded in the DC Hub transaction ledger. The same 48-hour window saw Meta announce a 298 MW capacity acquisition and Microsoft add 48 MW across two projects.
**Cheyenne, WY** remains the top-scoring US build market with a **69.5 excess-power index** and a constraint score of just 22.5, per the latest DC Hub DCPI update. Rural SPP (Kansas) follows at 67.2 excess. On the opposite end, **Dublin, OH** registers a **72.5 constraint score** — the highest avoidance signal in PJM — while European markets London (71.8 constraint) and Amsterdam (70.0) continue to face grid headwinds.
## What It Means
The KKR-Nvidia deal reflects a structural shift: infrastructure capital is now treating data center power and land as a discrete asset class, not just real estate. For site selectors, this means competition for the best excess-power markets (Wyoming, Kansas, parts of WECC) will intensify as financial sponsors chase yield in markets with sub-30 constraint scores.
The Dublin constraint score is a red flag for any PJM campuses banking on fast interconnection. If your capex model assumes 18-month timelines in Ohio, add 6-12 months or move to SPP/WECC zones with proven headroom.
## Methodology
DC Hub DCPI scores 280+ US and global markets daily using a composite of ISO interconnection queues, utility load forecasts, substation capacity, and regulatory timelines. Excess-power scores above 65 indicate low-risk build environments; constraint scores above 65 flag regulatory, grid, or land bottlenecks.
