## Highlights
Tulsa and Oklahoma City both registered 77.0 excess power on the DC Hub Power Index today, securing the second and third positions on the US top-build markets leaderboard behind Midland–Odessa (85.7, ERCOT). Both SPP metros combine deep grid headroom with materially different transmission constraints: Tulsa's constraint score of 49.1 runs 2.7 points tighter than Oklahoma City's 46.4, despite identical excess-power ratings.
This divergence within a single ISO reveals a critical site-selection nuance: excess power alone does not guarantee interconnection velocity. Tulsa's tighter constraint profile suggests denser local-network loading or fewer available feeder routes, while Oklahoma City's lower constraint reading points to a more distributed, flexible grid topology.
## What it means
For capacity planners, the twin-market signal suggests SPP's southern corridor can absorb 100+ MW clusters in either city, but time-to-power and capex phasing will diverge. Oklahoma City builds may clear transmission faster; Tulsa sites may require deeper network reinforcement or phased load ramps. For investors, the 2.7-point spread is material: it translates to weeks or months of interconnection delay and grid-upgrade cost, favoring Oklahoma City for fast-track hyperscale deployments and Tulsa for modularity-friendly, multi-phase campuses.
## Context
SPP now commands four of the top ten US excess-power markets overall. The emergence of two adjacent Oklahoma metros at identical surplus levels indicates that grid capacity in the southern Great Plains is both abundant and stable, not a single-site anomaly. Neither city has seen the capital repricing or deal density of Midland or Kansas hubs in the past 18 months, making both markets early-mover opportunities for operators willing to accept slightly longer interconnection timelines in exchange for lower land and power-purchase costs.
