Three markets across ERCOT, WECC, and SPP post back-to-back 70+ scores. Grid constraint spreads widen, favoring phased multi-site acquisition over single-market lock.
Midland–Odessa (ERCOT, TX) holds an 81.8/100 Excess Power score on the Data Center Power Index this week, with a Grid Constraint score of 23.1/100. Cheyenne (WECC, WY) posts 73.8/100 excess capacity and 25.5/100 constraint. Kansas City (SPP, MO) registers 72.9/100 excess power and 40.9/100 constraint.
The three markets represent the highest-scoring tier of US data-center build availability this week. Midland–Odessa's tight constraint (23.1) paired with dominant excess capacity signals a rare window: abundant power headroom with low grid friction. Cheyenne's 73.8 score reflects sustained WECC mountain-region tailwinds. Kansas City's 40.9 constraint—nearly double Midland–Odessa's—introduces a secondary tradeoff: more power, tighter transmission path.
Capacity planners with 100+ MW phased builds should weight the three markets by constraint tolerance, not excess power alone. A 36-month rollout that starts in Cheyenne (WECC, tight constraint, 73.8 excess) and staggers Phase 2 into Kansas City (SPP, wider constraint bandwidth, 72.9 excess) distributes grid-engagement risk. Single-market all-in strategies now face higher carry costs on grid coordination; the three-market tier width (81.8 → 72.9) signals durable regional supply, not isolated arbitrage.
Excess Power score combines available interconnection headroom, generation queue depth, and renewable penetration. Grid Constraint score reflects transmission utilization, peak-hour ramp limits, and balancing-authority reserve margins. Scores updated daily across 300+ markets. A 70+ Excess Power read with sub-45/100 constraint is actionable for immediate RFP issuance.
