Arkansas Interconnection Queue: 413 Projects

The fastest way into the Arkansas interconnection queue is the question most people actually arrive with: how many projects are waiting, and does that number mean anything? The Arkansas queue holds 413 projects, totaling 32.9 GW of requested capacity in our sealed snapshot of June 11, 2026.

The immediate caveat travels with every figure here: a queue position is a request to connect to the grid, not a built, approved, or financed plant. These lists are aspirational, and a large share of what sits on them never reaches steel in the ground. Arkansas proves it in the same dataset — 269 of those 413 requests are already withdrawn, a 65.1% withdrawal rate. This report is a cross-sectional census of one snapshot day; it counts what was published, not what will be built.

The Questions Readers Ask First

Q: How many projects are in the Arkansas interconnection queue?
A: 413 projects, totaling 32.9 GW of requested capacity, per the sealed snapshot of June 11, 2026. But that headline needs the next answer to mean anything.

Q: Does 413 projects mean 413 power plants are coming?
A: No. A queue entry is a request to connect, not a built plant. Of the 413, 269 are already marked withdrawn — 65.1% — so most of these requests will never energize.

Q: What fuel dominates the queue?
A: Solar, by a wide margin. Solar is 60.0% of the Arkansas queue: 248 of the 413 requests, totaling 20,613 MW.

Q: Which grid operator runs Arkansas's queue?
A: MISO is the dominant operator, holding 400 of the state's requests. A state's queue can span more than one operator, but MISO is the home of this slice.

Q: Is a 65.1% withdrawal rate normal?
A: It reflects aggressive filtering, not an error. Developers file early, before land and financing are locked; many requests drop as study costs land. MISO publishes withdrawn records, so Arkansas's 65.1% is visible rather than hidden by the feed.

Reading the 413 Honestly

That withdrawal share is the heart of the document. When a developer files an interconnection request, it stakes an early claim — often before land, financing, or offtake are secured. As study costs and network-upgrade estimates arrive, many of those claims are abandoned. Arkansas's 65.1% withdrawn means nearly two of every three requests that ever entered this slice have left it. So the right way to read 413 projects and 32.9 GW is not "32.9 GW of new generation arriving," but "a pipeline of developer intent, most of which will be filtered out."

• The Arkansas queue holds 413 projects at 32.9 GW, according to the sealed snapshot.

• 269 projects are already withdrawn — a 65.1% withdrawal rate.

• 141 projects remain active, a 34.1% in-queue share.

• Solar is 60.0% of the queue, the dominant fuel by count and capacity.

• The largest single request is ETTA at 770 MW, per the sealed snapshot.

More than three-fifths of every project that ever entered this Arkansas snapshot — 65.1% — is now marked withdrawn. The queue is a filter, not a forecast.

Arkansas at a Glance

The table pulls the state's headline figures directly from the sealed snapshot. Capacity appears in both megawatts and gigawatts as published; status is split into the buckets our methodology defines.

The 155 MW median, against a top request of 770 MW, says the queue is built from a broad base of mid-sized utility projects with a thin tail of larger ones — Arkansas has no mega-plant dominating the list. A small operational count of 3 confirms that the queue is overwhelmingly forward-looking intent rather than already-energized capacity.

The Fuel Mix Behind the Queue

Arkansas is a solar state in the queue sense, and the breakdown below — straight from the snapshot's keyword-grouped categories — shows how lopsided that is.

Solar makes up 60.0% of the Arkansas queue, an even more concentrated share than most states show. Read qualitatively, that points to where developers see the cleanest path: abundant land and falling module costs. The 70 hybrid and 65 battery-storage requests are the second story — storage chasing or pairing with solar to firm intermittent output. The thermal tail is vestigial: 6 natural-gas, 2 coal. New requests in Arkansas are overwhelmingly solar and storage, not conventional generation.

Solar accounts for 248 of Arkansas's 413 requests and 20,613 MW — a queue defined by one technology more than almost any other state in this snapshot.

The capacity-per-project split inside the fuel table is worth a second read. Solar spreads 20,613 MW across 248 filings, the broad-base profile of utility-scale arrays sized to available land. Wind concentrates 2,831 MW into just 18 requests, the denser profile of larger turbine farms, while hybrid carries 5,953 MW over 70 filings as developers bundle generation with storage.

Battery storage, by contrast, shows 65 requests but only 583 MW — a fleet of smaller, fast-deploying units rather than a few large installations. For anyone reading Arkansas as a forward order book, the technology signal is plain: solar leads on both count and capacity, storage and hybrid form the rising middle, and conventional fuels barely file at all.

How Arkansas Compares

Arkansas is a focused regional slice of a far larger national picture. Across all covered queues the snapshot holds 10,618 projects and 1600.7 GW. The table sets Arkansas against its parent operator and the national total; read the position qualitatively.

Arkansas's 60.0% solar share runs well above both MISO's 46.4% and the national 39.0% — one of the more solar-saturated state queues in the snapshot. For the operator-level view that contains Arkansas, see the MISO interconnection queue report; for the technology lens, the solar interconnection queue report.

A caution on cross-state status reads: withdrawal percentages are not always comparable, because some operators drop withdrawn projects from their feed entirely. Arkansas's MISO-published records carry a real 65.1% withdrawn figure; a slice showing 0.0% withdrawn is usually a feed that omits withdrawn records, not a queue where nobody left.

Methodology and the Grid Disclaimer

This report draws on public ISO/RTO interconnection-queue listings, via the grid-queue clock (sealed daily, content-hashed). The 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.

All figures are computed directly from US Tech Automations' 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. Vendor fuel and technology labels differ by ISO and are grouped into Solar, Battery Storage, Wind, Natural Gas, Hybrid and Other by keyword. Each ISO publishes its own status taxonomy; statuses are grouped into withdrawn, operational, still-in-queue, and unknown for feeds that publish no status. Some ISOs drop withdrawn projects from their feed entirely.

The grid disclaimer, restated: a queue position is a request to connect, not a built, approved, or financed project. Nothing here is a forecast of capacity that will come online. Arkansas's own 65.1% withdrawal rate is the clearest in-snapshot evidence of how aspirational these lists are.

How we build the snapshot:

1. Collect. We pull each covered ISO's published interconnection-queue feed on its own schedule.

2. Normalize. Differing vendor fuel and status labels are mapped onto common buckets.

3. Seal. The day's normalized records are content-hashed and stored append-only, so the snapshot is reproducible.

4. Aggregate. We compute counts, capacity totals, medians, and status splits across the sealed records for the snapshot date.

More Frequently Asked Questions

Q: What is the largest project in the Arkansas queue?
A: ETTA, at 770 MW, is the single largest request in the snapshot. Against a 155 MW median, it sits in a thin tail of larger projects rather than dominating the list.

Q: How much battery storage is in the queue?
A: 65 battery-storage requests, totaling 583 MW. With 70 hybrid filings on top, storage is the clear second technology behind solar in Arkansas.

Q: Can I compare Arkansas's withdrawal rate to other states?
A: Carefully. Some operators drop withdrawn projects from their feed, so a 0.0% withdrawn figure is a feed artifact, not a clean queue. Arkansas publishes withdrawn records, which is why its 65.1% looks high next to feeds that hide them.

Put Grid Data to Work

A sealed, daily queue snapshot is an early-demand signal, and each audience reads Arkansas's 413 projects differently.

Project developers siting the next request can read the 60.0%-solar mix and 155 MW median to gauge where the queue is crowded and where a differentiated filing might clear faster. EPC contractors and equipment suppliers can treat the 65 battery-storage and 70 hybrid requests as a forward order-book signal, timing inventory and crews to the technologies developers are actually filing. Utilities and policy researchers can track the 65.1% withdrawal rate as a measure of how much of the 32.9 GW is real intent versus speculative placeholders.

US Tech Automations builds the automation layer on top of that signal: watching the published feeds for changes, routing new or withdrawn filings to the right internal team, and drafting the first-pass outreach when a relevant project appears or moves. See the operator view in the MISO interconnection queue report and the national picture in the US interconnection queue index.
