24.8 GW of Power Is Queued in Missouri

Missouri's interconnection queue holds 24.8 GW of proposed generation and storage capacity across 178 projects, according to our sealed grid-queue snapshot dated June 11, 2026. That 24.8 GW figure places Missouri's queue in meaningful territory — for context, the total across all 5 covered ISOs and 28 states is 1600.7 GW nationally. A queue position is a request to connect, NOT a built, approved, or financed project, and Missouri's own status data underscores that reality: 43.3% of its 178 recorded entries have already withdrawn.

This report covers generation and storage projects sitting in the interconnection queues of the U.S. grid operators (ISOs and RTOs) that publish a machine-readable queue, as captured by our sealed daily grid snapshots. This is a census of the published queues, not of every project on every grid in the country. Missouri projects may span both the MISO and SPP footprints.

How Missouri Compares to Peer States

The comparison table is the right starting point for Missouri because the state's 24.8 GW reads differently depending on the reference frame. Against California's 416.8 GW or Texas's 453.7 GW, Missouri is a mid-tier market. Against neighboring MISO states like Wisconsin (27.1 GW) or Iowa (20.3 GW), Missouri is squarely in range. Against Mississippi (9.9 GW) or Nebraska (20.5 GW), Missouri sits meaningfully above.

What stands out in Missouri's row is that 178 projects carry 24.8 GW — a median project size of 199 MW. That median is notably higher than the national 150 MW, which means Missouri's queue skews toward larger individual proposals. Fewer, bigger projects rather than many smaller ones. That matters for how you read the market: each entry in Missouri's queue represents a more substantial development bet than a typical national queue entry.

Key Findings

• Missouri's queue holds 24.8 GW (24,803 MW) of proposed capacity across 178 projects, according to our sealed interconnection-queue snapshot.

• The median project size is 199 MW, above the national median of 150 MW — Missouri's queue skews toward larger-scale proposals.

• 43.3% of projects (77) have withdrawn, leaving 86 projects (48.3%) actively in-queue and 15 at operational status.

• Solar leads the fuel mix at 42.1% by project count, with 75 Solar projects and 7,435 MW of Solar capacity.

• The largest single entry is SIOUX at 2,200 MW, according to the sealed interconnection-queue snapshot.

• 15 projects have reached operational status in MISO's reporting for the Missouri footprint as of this snapshot.

Missouri's Queue at a Glance

The 15 operational entries are projects that MISO's feed explicitly marks as in-service or in commercial operation. That is a meaningful data point: it confirms that Missouri's MISO footprint has seen actual project completions reach the feed's operational status. Most state slices in this edition show zero operational entries; Missouri's 15 is one of the higher operational counts in the covered set.

The Fuel Mix Across Missouri's Pipeline

Solar accounts for 42.1% of Missouri's queue by project count, according to our sealed snapshot. That share exceeds the national Solar figure of 39.0% and reflects broad developer interest in Missouri's land and solar resource. The full fuel breakdown from the sealed display set is below.

A few observations worth drawing out qualitatively:

Solar and Battery Storage together form a dominant bloc. 75 Solar projects and 37 Battery Storage projects account for most of the queue by count. The storage pipeline at 4,993 MW is substantial — larger than the Wind capacity total — which suggests developers are pairing Missouri's grid access opportunities with storage solutions rather than treating storage as an afterthought.

Natural Gas carries outsized MW per project. Five Natural Gas entries account for 3,379 MW, making the per-project average for this fuel type well above the Missouri queue median of 199 MW. Natural Gas interconnection filings at this scale typically represent combined-cycle or large peaker projects seeking firm capacity agreements.

Coal and Hydro are marginal. Four Coal entries (1,240 MW) and one Hydro entry (60 MW) together represent a small fraction of the total. These are the tail of the Missouri fuel mix, not its direction.

Missouri's SIOUX entry at 2,200 MW is the largest single project on record in this snapshot. SIOUX appears in MISO's largest-project field. A single entry of this size represents a major transmission or generation proposal; its presence lifts Missouri's total queued capacity and average project size above what the project count alone would suggest.

Status Distribution: 15 Operational Projects Stand Out

Missouri's status split carries a signal that most MISO state slices do not: 15 projects with operational status in the feed. Across the national snapshot, only 290 projects out of 10,618 carry operational status — Missouri's 15 represents a measurable share of that small national operational cohort.

The 43.3% withdrawal rate (77 projects) is close to the national figure of 36.5% and to the MISO-wide rate of 56.2%. Missouri's withdrawal attrition is neither unusually high nor unusually low; it reflects normal queue cycling in MISO's territory. The 86 projects still in-queue are the current working pipeline.

Missouri's 15 operational entries stand out against a national operational cohort of just 290 projects. Most MISO state slices in this edition show zero operational entries, which makes the Missouri footprint's completion record an unusual signal rather than a typical one.

Methodology

Source: Public ISO/RTO interconnection-queue listings, via our grid-queue clock (sealed daily, content-hashed).

Honesty statement: All figures are computed directly from our sealed daily grid-queue snapshots; nothing is estimated, modeled, or extrapolated. Fuel and status labels are grouped from each ISO's own categories, and the grouping rules appear in the display set.

Scope: Generation and storage projects sitting in the interconnection queues of the U.S. grid operators (ISOs and RTOs) that publish a machine-readable queue, as captured by US Tech Automations' sealed daily grid snapshots. This is a census of the published queues, not of every project on every grid in the country.

The grid disclaimer: A queue position is a request to connect, NOT a built, approved, or financed project. Nothing in this report implies that queued capacity will be built or is coming online. A large share of projects withdraw before construction.

Fuel bucketing: Vendor fuel and technology labels differ by ISO and are grouped into Solar, Battery Storage, Wind, Natural Gas, Hybrid and Other by keyword.

Status bucketing: Each ISO publishes its own status taxonomy; statuses are grouped into withdrawn, operational (explicitly in-service or commercial operation), still-in-queue, and unknown for feeds that publish no status. Some ISOs drop withdrawn projects from their feed entirely.

How the clock works:

1. Collect. The research desk pulls each ISO's machine-readable queue listing daily.

2. Normalize. Project records are parsed, fuel and status labels bucketed by keyword rules, and state attribution assigned by the ISO-reported point of interconnection.

3. Seal. Each daily snapshot is content-hashed (SHA) into an append-only ledger. The snapshot here carries hash prefix 4938600b6a99772e, sealed June 11, 2026.

Frequently Asked Questions

Q: What does 24.8 GW queued in Missouri actually represent?
A: It is the total rated capacity across all 178 interconnection queue entries attributed to Missouri's grid footprint, including both active and withdrawn projects. The 24,803 MW total spans Solar, Battery Storage, Wind, Natural Gas, Hybrid, and other fuel types across MISO's Missouri territory.

Q: Why do 15 projects show as operational when most states show zero?
A: MISO's feed explicitly marks some projects as in-service or in commercial operation, and 15 Missouri entries carry that designation. This is not common across all MISO states — most state slices show no operational entries — suggesting Missouri's MISO footprint has a history of projects that have run through the full interconnection process to completion.

Q: How does Missouri's median project size of 199 MW compare nationally?
A: The national median across 5 covered ISOs is 150 MW. Missouri's 199 MW indicates that projects filing in Missouri's footprint tend toward larger-scale proposals than the national average. Fewer, bigger entries rather than many smaller ones.

Q: Can I use this data to identify who is developing what in Missouri?
A: The sealed snapshot contains project names (like SIOUX) as reported by the ISO, but does not contain developer identity or contact information. ISO queue filings are public records, but enriching them with developer identity requires separately consulting ISO project detail pages or commercial data services.

Who Works With Missouri Queue Data

Three categories of professionals typically consume interconnection queue data for Missouri's footprint, and each reads the sealed numbers differently.

Project developers watch Missouri's MISO territory for capacity saturation at specific substations and voltage buses. When the 86 still-in-queue projects cluster at certain interconnection points, new applicants face longer queues and higher assigned upgrade costs. The 199 MW median project size tells a developer that Missouri attracts substantial utility-scale proposals — the competitive landscape for transmission access is not small-scale.

Equipment suppliers and EPC contractors use the 86 active projects as a demand signal. Solar panels, inverters, Battery Storage systems, and Wind turbines all require long supply-chain lead times. Suppliers tracking Missouri's queue monitor new entries, note project MW ratings, and use that information to pre-position inventory or build relationships with queue holders before project financing closes.

Policy researchers and utilities care about the status split: 86 in-queue, 77 withdrawn, 15 operational. The 15 operational projects confirm that Missouri's MISO footprint has seen projects run the full process to completion. The 77 withdrawn inform estimates of attrition rates in future capacity planning scenarios. Neither number is a forecast — they are a census of what has happened in the queue as of June 11, 2026.

US Tech Automations automates the ingestion and alerting workflow for teams in all three categories: queue feeds pulled on schedule, new entries flagged, withdrawal events logged, and signals routed to the right teams without manual spreadsheet maintenance.

Tracking Missouri's Queue Without Manual Spreadsheet Work

Project developers, EPC contractors, equipment suppliers, and energy policy teams that monitor the Missouri interconnection queue today typically do so by pulling MISO's queue files manually, reformatting them, and reconciling changes. That process breaks every time MISO updates its file format or release schedule.

The platform automates that ingestion workflow: structured queue feeds are pulled on a schedule, project entries are normalized, and alerts fire when a new project appears in Missouri's footprint or an existing entry changes status. The same automation layer can feed dashboards, downstream procurement models, or CRM routing for sales teams targeting developers in the queue.
