Where natural gas can power AI data centers when the grid can’t. Grid interconnect queues run 5–7 years — so behind-the-meter gas is how capacity gets energized now.
The Data Center Gas Index (DCGI) is not published while two of its three terms are wrong. It is not delayed or degraded — an internal audit on 2026-08-08 found defects that no caveat would make safe to read, so the whole ranking came down rather than part of it staying up.
1. The interstate-share term was dead. It carries 20 of the 100 access points. It compared a lowercase literal against EIA’s capitalised TYPEPIPE values, so it scored near zero for all 53 published states — Texas showed 7 interstate segments against 6,731 tracked.
2. The cost term was a constant for nine states, including Texas. It carries 40% of the composite. Where the EIA price table held no row it fell back to a hardcoded 50.0, and Texas was published at DCGI 68.0, rank #3, GAS-ADVANTAGED on that constant. Where a price did exist it was chosen by a non-deterministic tie-break between two EIA series that carry different margins.
Still published on this page and unaffected: natural-gas segment counts and the parent-midstream registry. Neither uses the price term. The scoring definition stays up →
