West Texas market leads the ISO with 22.8 constraint and immediate gas access; ERCOT average holds 64.7 excess across tracked markets
## Highlights
Midland–Odessa, TX scored **85.7 on the DCPI excess-power index** this week—the highest of 21 data-center markets tracked in ERCOT and 12 points above the ISO's 64.7 average. The West Texas market's constraint score of 22.8 indicates minimal grid congestion, positioning it as ERCOT's strongest combination of available capacity and low interconnection friction.
## What It Means
ERCOT's 21-market footprint now averages **64.7 excess and 54.0 constraint**—materially stronger than PJM's 48.2 excess median but still below MISO's rural zones. Midland–Odessa's 85.7 excess reflects direct access to Permian Basin gas infrastructure and lower competing load than Austin or Dallas metro zones. For hyperscalers evaluating ERCOT builds, the 12-point gap between Midland and the ISO average translates to earlier energization dates and lower substation upgrade costs.
The second-order read: Midland's score separates **commodity power availability from metro fiber density**. Markets scoring above 80 excess typically lack established carrier hotels, forcing hybrid strategies—colocation in Dallas for latency-sensitive edge workloads, owned campuses in Midland for training clusters. The 22.8 constraint score suggests projects under 100 MW can likely avoid multi-year ERCOT queue delays that now stretch Metro Houston timelines past 2028.
## Methodology
DCPI excess scores aggregate real-time ISO queue data, utility planning filings, substation headroom, and gas/renewable pipeline proximity. Constraint scores weight interconnection study backlogs, transmission upgrade costs, and historical queue withdrawal rates. Updated daily.
