MISO
An empty-looking queue over the market building the most new gas in America.
0.4GW
Deliverable gas
74GW
Existing gas
15.1GW
Planned gas
Deliverable = signed interconnection agreement, in service by 2028, merchant (reconciled from the ISO's own queue). Existing and planned from EIA-860M.
MISO's interconnection queue holds 66.5 GW of gas, but only about 0.4 GW is signed, near-term, and still to be built. By the merchant-queue test that works in ERCOT, MISO looks empty. That reading is misleading, because MISO is a regulated market of vertically integrated utilities. The gas is not in the merchant queue; it is in utility resource plans.
Follow what is actually being built and MISO leads every organized market: about 15 GW of planned gas, with Louisiana alone leading the entire country at roughly 6.8 GW, much of it Entergy capacity tied to serving new large-load and data-center demand. The empty queue and the nation-leading build are the same market seen two ways.
In MISO the firm-power counterparty is the regulated utility, and the timeline is a resource plan, not a queue slot. Louisiana and the Entergy South footprint is the live firm-gas market.
