## Highlights
**Midland–Odessa, Texas (ERCOT) posted 85.7 excess power this week—the highest absolute capacity score among all tracked US data-center build markets.** More significantly, its constraint ratio stands at 22.8%, the lowest of the top three markets. This pairing reveals that Midland–Odessa offers not just available power, but the cleanest path to grid without transmission bottleneck friction.
By contrast, Tulsa and Oklahoma City (both SPP) rank second and third on excess power at 75.9 and 75.6, respectively—but their constraint ratios of 49.6% and 47.7% indicate each megawatt of load faces nearly 2.2× the transmission resistance. For a 300 MW data center, that difference translates to capex risk on line reinforcement and queue delay.
## What It Means
**Siting teams evaluating power-rich markets must now weight constraint ratio alongside excess capacity.** A site with 75 MW excess power but 50% constraint ratio is materially different from one with 85 MW excess and 23% constraint. Midland–Odessa's low constraint score signals that ERCOT's transmission spine in that corridor has absorbed recent build-out and remains responsive. Oklahoma's SPP markets, by contrast, show the canonical pattern: abundant renewable generation but pinched interconnection gates.
For hyperscalers with hard power-on timelines, Midland–Odessa now represents the lowest-friction entry point in the continental US: maximum excess power, minimum transmission risk. Colocation operators pricing lease terms should expect Midland–Odessa to command a premium for that clarity.
## Methodology
Excess Power reflects available capacity above historical peak load. Constraint Ratio measures the percentage of queued interconnection requests awaiting approval—a proxy for transmission headroom utilization. Markets with constraint ratios below 30% are considered to have responsive interconnection pathways. Source: DC Hub Data Center Power Index (https://dchub.cloud/dcpi). Updated daily.
