MISO
An empty-looking queue over the market planning the most new gas of any ISO.
~0GW
Signed, near-term gas
73GW
Existing gas
18.8GW
Planned gas
Signed, near-term gas = merchant projects with a signed interconnection agreement and requested operation by 2028, from the ISO's own queue, with ownership checked project by project where the queue does not name developers. Existing and planned from EIA-860M, August 2026.
Updated October 2026 from MISO's interconnection queue of October 4, 2026. Existing and planned gas are from EIA-860M, August 2026.
MISO's interconnection queue holds 66.5 GW of gas, but only two projects are signed and due by 2028, and none is confirmed merchant. The 0.12 GW Louisiana project is a utility plant that EIA now lists as cancelled, though MISO's file still carries it. The 0.33 GW Illinois project sits at an industrial site in Decatur, and its owner could not be established from public records. MISO's queue has no developer field, so we checked each project against EIA-860M and state filings. Confirmed merchant signed, near-term gas is zero, and 0.33 GW at most.
By the 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 queue position: the gas is in the utility's plan, not the queue.
Follow what is actually being planned and MISO leads every organized market: about 18.8 GW of planned gas, with Louisiana at about 8.8 GW, all of it Entergy Louisiana's and most of it still before regulatory approval. By state, Texas now leads the country, at about 20 GW.
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.
