Oklahoma City Ranks Fifth in the US on Excess Power at 76/100—SPP Corridor Maintains Top-Tier Build Profile Despite 47% Constraint Ratio

## Highlights

Oklahoma City scored **76.5 on the DC Hub excess-power index** this week, placing it fifth among all tracked US markets and second in the Southwest Power Pool behind only Tulsa (76.5, constraint 49.2%). The reading represents some of the strongest power headroom in the country—comparable to ERCOT's Midland–Odessa (85.7) and MISO's Upper Peninsula Michigan (74.4)—but OKC's **constraint ratio sits at 47.1%**, meaning nearly half the queued capacity faces transmission bottlenecks or interconnection delays.

## What It Means

Oklahoma City remains on the short list for hyperscale builds targeting available power, but **time-to-energization is no longer a given**. A 76+ excess score signals fuel, generation, and substation capacity exist; a 47% constraint ratio signals projects compete for limited interconnection slots or require costly network upgrades. Developers should verify substation capacity, NTP timelines, and whether the local utility (OG&E) has already allocated queue priority to anchor tenants.

For site-selection leads comparing SPP markets, **Tulsa offers the same 76.5 excess score with a marginally higher 49.2% constraint**, suggesting both metros face similar transmission pressure. Rural SPP nodes in western Oklahoma or northern Kansas may offer faster interconnection with less queue congestion, though land and fiber become the new constraints.

## Methodology

The **DC Hub Data Center Power Index (DCPI)** scores 280+ global markets on excess generation, grid constraint, interconnection queue depth, and utility policy. Updated daily. Scores range 0–100; >70 signals strong build headroom, <40 signals avoid or multi-year delay risk.
