SPP's Oklahoma Markets Rank Dual Top-5 Build Leaders on DCPI; Tulsa and Oklahoma City Both Post 75.3/100 Excess Power

## Highlights

**Oklahoma City and Tulsa both posted 75.3/100 Excess Power scores on DCPI this week**, joining the top five strongest capacity markets in the US. Oklahoma City carries a 39.9/100 grid constraint; Tulsa, 43.3/100. Both metrics reflect robust generation headroom paired with moderate transmission pressure—the profile that typically signals shortest time-to-energization for large loads in the 5–50 MW range.

**Midland–Odessa (ERCOT) remains the national leader at 86.4/100**, with constraint at 20.1/100—the lowest grid friction in the tracked markets. The three-market cluster (two SPP, one ERCOT) now accounts for the majority of US capacity opportunities in the current build window.

## What it means

Site-selection teams evaluating Oklahoma deployment can now rely on dual, validated alternatives. Tulsa's slightly higher constraint (43.3 vs Oklahoma City's 39.9) reflects tighter interconnection feeder conditions, but both markets clear the 70/100 Excess Power threshold at which capex timelines and land-hold costs stabilize. For hyperscalers mid-construction in ERCOT South or considering secondary capacity, SPP's Oklahoma pair represents genuine geographic and grid-diversity value—especially given SPP's lower interconnection-queue depth relative to MISO and PJM.

## The build implication

When two metros in the same ISO both rank in the top five, it typically signals that the ISO's generation pipeline is outpacing demand, not that one market has isolated strength. SPP's overall generation-to-load balance suggests a 12–18 month window before constraint begins to compress these scores downward. Capacity planners should view this as a signal to close land options and lock engineering before Q2 2027, not as a durable advantage.
