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. Much of MISO, especially MISO South, is served by vertically integrated regulated utilities. In those territories new firm generation runs through utility resource planning rather than a merchant queue position: 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.
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.
