SPP Leads U.S. Grid Capacity With Four Markets Above 72/100 DCPI—Oklahoma City, Tulsa, Kansas City and Rural SPP Claim Half the Top-Eight Build Zones

## SPP's Four-Market Sweep

Southwest Power Pool (SPP) now claims four of the eight strongest data-center build markets in the United States, according to DC Hub's DCPI this week. Oklahoma City and Tulsa both posted 75.3/100 Excess Power scores, Kansas City hit 73.7/100, and Rural SPP registered 72.4/100. All four markets hold Grid Constraint scores below 44/100—Oklahoma City at 39.9/100, Tulsa at 43.3/100, Kansas City at 39.6/100, and Rural SPP at 19.5/100—indicating manageable interconnection timelines relative to PJM, MISO, and constrained ERCOT metros.

## What It Means for Site Selection

SPP's sustained depth across multiple geographies changes the risk calculus for portfolio diversification. A hyperscaler or developer building in two SPP markets instead of splitting between PJM and MISO cuts energization-delay exposure while preserving latency reach into Chicago, Dallas, and Denver. The ISO's transparent interconnection queue and lower regulatory friction make these scores structurally stable, not a temporary anomaly.

North Kansas City—a distinct market from Kansas City proper—also posted 73.7/100 Excess Power but with a tighter 31.8/100 constraint score, suggesting localized substation or transformer capacity limits even as the broader ISO holds headroom. Site teams evaluating Kansas City metro should model both markets separately; one may clear permitting and energization 6–12 months faster.

## Midland–Odessa Retains Top Rank; WECC and MISO Round Out Leaders

Midland–Odessa, TX (ERCOT) held the highest U.S. score at 86.4/100 Excess Power with a 20.1/100 constraint rating. Cheyenne, WY (WECC) ranked fourth nationally at 73.8/100, and Upper Peninsula MI (MISO) posted 71.7/100 with a 17.0/100 constraint score—the lowest congestion risk in the top eight. The Upper Peninsula's remote location and fiber-sparse connectivity make it a specialist play for workloads that tolerate higher latency or require physical isolation.
