47.1% of Texas's Queue Is Battery Storage

Battery Storage is the single largest technology in the Texas interconnection queue. On June 11, 2026, 955 battery projects made up 47.1% of the state's filings — the only large state in our snapshot where storage, not solar, sits on top. Across all technologies, Texas held 2,029 projects worth 453.7 GW of proposed capacity.

A queue position is a request to connect to the grid, not a built, approved, or financed project. These are filings, and many filings are withdrawn or stall before commercial operation. This report is a cross-sectional snapshot of one sealed day — no trends, no forecasts.

Battery Storage leads the Texas queue at 47.1%, ahead of solar, across 2,029 total projects.

Battery Storage: The Texas Story

Lead with what makes Texas distinct. Storage is the state's queue centerpiece, and the size of each filing is as striking as the count.

955 battery projects carry 167,315 MW of proposed capacity, edging solar's 699 projects and 158,370 MW on both counts. The storage tilt fits a grid that has absorbed enormous solar and wind already and now needs to shift and firm it. Natural gas holds a meaningful 125 projects and 64,004 MW — larger per project than most other buckets — while wind sits at 203 projects despite Texas's wind reputation. There is even one nuclear filing at 1,337 MW.

The storage dominance reframes how to read the whole queue. A grid that files more battery capacity than solar capacity is one where developers expect the bottleneck to be timing, not raw generation. Texas already produces enormous midday solar and gusty overnight wind; what it lacks is the ability to move that energy to the hours that pay best. The 167,315 MW of proposed storage is a bet on that arbitrage. This Texas concentration is a major reason the battery storage interconnection queue is the second-largest technology bucket nationally.

A note on how to use these capacity figures: they are nameplate values from each filing, never delivered energy. We do not sum, annualize, or convert them. The 167,315 MW storage figure is the gross proposed nameplate on file in Texas on one sealed day — a measure of intent, with the disclaimer attached.

Texas has 955 queued battery projects totaling 167,315 MW of proposed capacity.

Walking the Rest of the Queue

With the fuel mix framed, here is the state slice at a glance. Most of these projects run through ERCOT, the Texas grid operator, though a state's queue can span more than one ISO.

The median Texas project is 201 MW, the largest median among the states in this edition — Texas developers file big. The largest single entry is Prairie Ridge (Gas - CC) at 1,660 MW, a combined-cycle gas plant, even though storage dominates by count.

That pairing is telling. A queue can be dominated by one technology on count while its single biggest filing belongs to another, and Texas is exactly that case: 955 battery projects set the texture of the queue, but the one largest nameplate is a dispatchable gas plant. It is a reminder not to collapse a queue into a single headline. The median, the top fuel, and the largest project each answer a different question — how big is typical, what is most common, and what is the outlier — and in Texas those three answers point in three different directions.

Now the honesty point. Texas shows only 66 withdrawn projects, a 3.3% rate, with 1,933 still in queue and 30 operational. That looks impossibly clean next to California's 77.5%. It almost certainly is a feed artifact: ERCOT's published statewide withdrawn rate in our snapshot is 0.0%, which signals the feed drops withdrawn projects rather than that nearly none withdrew. Do not read Texas's low number as a sign that its projects survive at high rates. Read it as a different feed convention. The full ERCOT breakdown, including this status quirk, sits in the ERCOT interconnection queue report.

The practical consequence is that you cannot compare Texas's 3.3% withdrawn rate against California's 77.5% as if they measure the same thing. California's grid operator publishes withdrawn projects and so reports honest attrition; ERCOT appears to remove them. Two states can run identical real-world attrition and still show wildly different headline rates purely because of feed design. When you see a near-zero withdrawn figure anywhere in this edition, treat it as missing data, not as evidence of healthy survival.

How Texas Compares

Set Texas beside the other large state queues from the same sealed day. This is a qualitative position, not a computed ranking.

Texas trails California slightly on project count — 2,029 to 2,076 — but leads on proposed capacity at 453.7 GW and carries the largest median project at 201 MW. It is also the lone large state where the top fuel is Battery Storage rather than Solar. Among the five ISOs in this edition, ERCOT's top fuel is Battery Storage at 50.1%, reinforcing the state-level pattern.

What does not transfer across this table is the withdrawn column, and that is the single most important caveat for a cross-state read. California's 77.5% and Texas's 3.3% are not measuring the same reality; they are measuring two different feed conventions. So when this comparison shows Texas as the capacity leader with a near-pristine withdrawn rate, resist the inference that Texas projects survive better. The capacity and median figures are comparable; the status figures are not. Hold those two facts separately and the table becomes a fair read rather than a misleading one.

Methodology

Source: Public ISO/RTO interconnection-queue listings, via the US Tech Automations grid-queue clock (sealed daily, content-hashed). The scope is 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.

Vendor fuel and technology labels differ by ISO and are grouped into Battery Storage, Solar, Wind, Natural Gas, Hybrid and Other by keyword. Status taxonomies also differ; we group them into withdrawn, operational, still-in-queue, and unknown for feeds that publish no status. Some ISOs drop withdrawn projects from their feed entirely — which is why Texas shows a 3.3% withdrawn rate and ERCOT shows 0.0% statewide. That is a feed artifact, not a claim that nothing withdrew.

Reminder on the disclaimer: a queue position is a request to connect, not a built, approved, or financed project. We make no forecast that any queued capacity will be delivered.

How the clock seals each snapshot:

1. Collect each ISO feed. Across this edition, 5 ISOs spanning 28 states.

2. Normalize labels. Map each vendor's fuel and status onto our shared buckets.

3. Bucket status and fuel. Sort every project into the standard categories.

4. Seal the snapshot. Hash the normalized day and append it to the immutable ledger.

Frequently Asked Questions

Q: Why does Texas show only a 3.3% withdrawal rate?
A: Because ERCOT's feed appears to drop withdrawn projects. The 3.3% figure and ERCOT's 0.0% statewide rate are feed artifacts, not evidence that Texas projects rarely withdraw.

Q: Is Texas really more storage-heavy than solar-heavy?
A: In the queue, yes. Battery Storage is 47.1% with 955 projects, ahead of solar's 699. That reflects what developers are filing, not what is built today.

Q: Does a queue spot mean a Texas project is approved?
A: No. A queue position is a request to connect, not a built or financed project. Of 2,029 filings, 1,933 are still in queue and only 30 are operational.

Q: How big is the typical queued Texas project?
A: The median is 201 MW, the largest median among the states this edition. The single biggest filing is Prairie Ridge (Gas - CC) at 1,660 MW.

Q: Can I reproduce these Texas numbers?
A: Yes. The June 11, 2026 snapshot is content-hashed and sealed, so the 2,029-project and 955-battery figures are fixed and auditable.

Put Grid Data to Work

The Texas queue speaks to distinct teams. Storage developers and battery integrators can read the 955-project, 167,315 MW storage pile to see exactly how crowded the segment they are entering already is before committing capital to a filing.

Gas and dispatchable-power planners can track the 125 natural-gas filings and the 1,660 MW Prairie Ridge entry as the dispatchable counterweight to all that intermittent generation.

Grid analysts and policy teams should treat the 3.3% withdrawn figure with care — the 1,933 still-in-queue count is the more meaningful read of live Texas intent, and the 30 operational projects are the only ones the feed marks as actually built. Each team works from the same sealed file but asks a different question of it, which is why a single snapshot can serve developers, suppliers, and analysts at once.

US Tech Automations automates this queue monitoring end to end: detecting new filings, flagging status changes, and routing the right project to the right analyst. Teams can wire that into their workflow through our agentic workflows platform, with the raw sealed snapshots at https://permits.ustechautomations.com.
