The gas analog to DCPI. Every US state scored on natural-gas suitability for siting AI data-center power load. Grid interconnect queues run 5–7 years — so behind-the-meter gas is increasingly how AI capacity actually gets energized this decade. No one else scores the gas behind the grid.
Gas is how capacity gets energized when the grid can’t. DCPI scores the grid itself — where the interconnection queue is dead and where stranded excess power is hiding in plain sight across U.S. markets.
DCGI = 0.60 × Gas Access + 0.40 × Gas Cost. Gas Access blends pipeline density, midstream-operator diversity and interstate share (the EIA geofeed publishes no per-segment throughput, so this is a relative infrastructure-presence index). Gas Cost inverts the latest industrial / electric-power delivered gas price ($/Mcf). Verdicts: GAS-ADVANTAGED (dcgi ≥ 62 & access ≥ 50), ADEQUATE (dcgi ≥ 42), GAS-CONSTRAINED (below).

Parent midstream companies mapped to the FERC pipeline entities they operate, with live segment counts. The value-add no one else publishes: which megacap actually controls the gas under this market.
