The Second-Largest Signed, Near-Term Gas Queue Is in the Plains

The Plains barely register in the data-center power conversation. Yet after ERCOT, the largest signed, near-term gas queue in the country is SPP's.

The overlooked signed-gas market in the Plains

Two gigawatts is not a large number. What makes it notable is the contrast: a wind-dominated market quietly holds more signed, near-term gas than the markets that get all the attention, concentrated in Oklahoma and the Texas Panhandle.

Much of SPP is served by vertically integrated utilities, so a large share of its gas build runs through the utility rather than a merchant field. But its queue reads more cleanly, because SPP marks executed interconnection agreements explicitly. The 2.0 GW is that subset, the fully executed, signed positions, distinct from the broader utility resource-plan build. It is screened on executed agreements and timing, not on merchant ownership, so it may include some utility positions.

What this changes for the buyer

Data centers. Oklahoma pairs lower-cost land, existing gas infrastructure and a small signed, near-term gas set that warrants project-level diligence. The 2 GW screened set alone does not support a multi-gigawatt campus, but it is a secondary market most site searches skip. The Texas Panhandle sits in SPP, not ERCOT, so it is a different queue and a different market when you compare Texas options.

Developers. A signed, near-term gas position in Oklahoma is scarcer than the Plains' low profile suggests. As the marquee markets tighten, secondary signed, near-term gas positions gain option value.

Methodology

The 2.0 GW screened figure is reconciled from SPP's public generator interconnection queue (the active-queue CSV export): gas with a fully executed interconnection agreement, on schedule, not yet in commercial operation, and a 2026 to 2028 commercial operation date. It is Tafel Power's filtered estimate, not an SPP-published category. The screened set identifies projects meeting public queue criteria. It does not establish that the capacity is uncontracted, commercially available, financed, equipment secured, fuel secured, or physically deliverable to a particular load. Figures reflect an early-2026 snapshot and may have changed since.
