ERCOT interconnection queue

Explore future generation and storage projects by county, publication date, technology, status, and proposed delivery year.

Open and configure the queue

The queue is an ERCOT-only infrastructure layer built from Ask the Grid's canonical mirror of ERCOT's NP4-198 GIS Report.

The ERCOT map with Brewster County's interconnection queue selected and the Map content panel showing the official publication, expected-online-by years, and technology filters.
The queue shares the map clock while keeping publication, delivery-horizon, technology, status, labels, provenance, and limitations together in Map content.

Turn on the ERCOT queue

Open Map content, expand Infrastructure, and turn on Interconnection queue. Select the layer name or arrow to open its full settings, source, connected dataset, and known limitations.

  1. 1Open the ERCOT map and select Map content.
  2. 2Under Infrastructure, turn on Interconnection queue.
  3. 3Open the layer detail to configure time, labels, technology, and ERCOT status.

The layer is available only on ERCOT because this release uses ERCOT's official queue publication rather than combining unlike queue feeds across markets.

Move between publication and delivery views

At live now, the map uses the latest official publication. Move the global map clock into the past to see the queue vintage available at that time, or move it into the future to show active projects whose ERCOT proposed completion date falls on or before that horizon. The queue's Map time section also provides adjacent publication controls and quick expected-online-by years.

A future view is a schedule-of-intent screen, not a forecast of which projects will reach commercial operation.

Filter without losing your setup

Choose battery, solar, wind, gas, nuclear, hydro, or other technologies, and include Active or Completed ERCOT feed statuses. Hiding the queue preserves those choices; Reset layer restores the queue's own defaults without disturbing other map layers.

Read counties and projects

County shading summarizes the projects matching the active time and filters; selecting a county opens the project-level path.

The ERCOT queue county card beside Map content filters, the requested-capacity legend, data coverage, source, and connected catalog dataset.
County summaries stay beside the exact filters and source contract that produced them.

Read the county overlay

Darker counties represent more requested interconnection capacity within the current queue view. County labels show the active aggregate, and the county card separates project count, requested MW, official snapshot, expected-delivery cohorts, and changes from the prior publication when those measures apply.

Open a project from the county card

The Expected projects or County projects section is a drill-down list. Each bordered row has a project marker and chevron; select one to replace the county summary with that project's official queue fields and history.

  1. 1Select a shaded Texas county.
  2. 2Review the map-time label and county totals.
  3. 3Select a project row to open its queue record.

Ask about what is selected

The grid agent receives the selected county FIPS or queue project ID and can query the canonical ERCOT queue dataset for project identity, developer, technology, requested MW, status, point of interconnection, and proposed dates. Ask a precise question such as “what changed for this project?” or “which active battery projects are in this county?”

The selected card is navigation context, not evidence by itself. The agent is instructed to verify factual claims against the official queue table.

Inspect project history

The Three Ranches Solar queue-project card showing queue ID, technology, requested capacity, ERCOT status, county, developer, point of interconnection, dates, project history, and a back button.
A project keeps its official identity and change history, with a direct path back to the county list.

Read one official queue record

The project card shows the queue ID, technology, requested capacity, ERCOT feed status, county, interconnecting entity, proposed point of interconnection, queue date, and proposed completion date when published.

Follow changes across publications

Project history compares official snapshots so capacity, status, and proposed-completion changes remain attached to the same queue ID. Use the back arrow to return to the filtered county list without rebuilding the map view.

Interpret the data correctly

The map preserves ERCOT's source semantics and makes the important boundaries visible wherever the data appears.

Requested MW is not operating capacity

Queue capacity is the amount requested for interconnection. It is not installed, operating, accredited, approved, or likely-to-complete capacity, and it does not establish available transmission headroom.

Dates and statuses need context

A proposed completion date is an ERCOT queue field, not a delivery guarantee. “Completed” is ERCOT's feed status and is not, by itself, proof of commercial operation. Compare official snapshots before describing a project's current state or change.

County placement is approximate

The public feed does not publish exact project geometry, so Ask the Grid joins projects to Texas counties and places map interactions at county centroids. A named point of interconnection is useful location evidence, but not a thermal-loading, feasibility, or study-outcome measurement.
