Where Texas Solar Farms Are Located

When a solar project is rumored, proposed, or under contract nearby, the most useful question is not “is there a solar farm coming?” but “what do the official records actually establish, today?” This page is a research guide to those records — the same role our Where Texas Data Centers Are Located page plays for data centers.

Read this first

No single Texas database, by itself, establishes a complete list of every proposed, under-construction, registered, operating, delayed, transferred, or canceled solar project. Each official source below establishes something specific — and only that. Careful research combines them, states what each source shows, and resists filling the gaps with assumptions.

1. PUCT Interchange filing search

The Public Utility Commission of Texas maintains a public filing system, the PUCT Interchange, containing dockets, applications, registrations, and other filings. Users may search by control number, utility type, utility name, filing party, case style, filing description, item type, and filing date. Company names, project names, and county names all make workable search terms; because project entities are often special-purpose LLCs, search variants of the name.

What it can establish: that a specific entity made a specific filing on a specific date — a registration, an application, a report, a docketed proceeding.

What it cannot establish: that a facility was built or is operating. A filing is a filing. Registrations can precede construction by years, and dockets can involve projects that are later delayed, sold, or canceled.

2. PUCT directory of power generation companies

Companies that generate electricity for sale in Texas generally register with the PUCT as power generation companies, and the PUCT publishes directories of registered entities on puc.texas.gov.

What it can establish: that a company holds a current registration to do business as a power generator in Texas.

What it cannot establish: a parcel-level project list. A registration belongs to a company, not to a tract of land, and one company may be associated with many projects — existing, planned, or abandoned. Company registration is not proof that any particular project exists, is located in any particular county, or is operating.

3. ERCOT resource entities — and what the registration terms mean

Most utility-scale Texas solar connects to the grid operated by the Electric Reliability Council of Texas. ERCOT’s registration framework, described in its registration materials at ercot.com, uses precise terms that are easy to blur and important to keep separate:

Resource Entity: an entity that owns or controls a Generation Resource, a Load Resource, or a Non-Modeled Generator and registers with ERCOT in that capacity. Registration of the entity is not registration of a completed plant.
Generation Resource: a generator meeting ERCOT’s definitions and size thresholds that is modeled in ERCOT’s systems. ERCOT’s materials describe different registration treatment for generation resources at or above and below 10 MW, and registration expectations for distributed generation above 1 MW.
Qualified Scheduling Entity (QSE): the market participant that schedules and settles with ERCOT on a resource’s behalf. A QSE relationship is a market arrangement, not a construction milestone.
Interconnection request: a request — processed through ERCOT’s generation interconnection or change process and its Resource Integration (RIOO) tools — to study and eventually connect a project to the grid. Many requests are studied; not all are built.
Asset registration: submission of resource asset registration information (ERCOT’s registration forms) for a specific project as it moves toward the grid — a later step than an interconnection request, but still not commercial operation.
Commissioning: the testing and energization phase, with settlement metering in place, before full operation.
Commercial operation: the point at which a resource has completed ERCOT’s qualification steps and operates in the market.

ERCOT’s interconnection and registration materials also describe related obligations — such as emergency operations plans and weatherization requirements for resources — that attach as projects register and operate.

The most common research error

Treating an interconnection request as proof a project will be constructed. It is not. Requests are routinely withdrawn, delayed, resized, or transferred. An interconnection request establishes exactly one thing: that a request was submitted for study.

4. County and local records

The records most likely to tie a project to specific land are local:

County clerk real-property records: recorded memoranda of option or lease, solar and transmission easements, access easements — the instruments that actually encumber identified parcels.
County appraisal district: parcel ownership, improvements, and changes in appraisal treatment.
Commissioners court agendas and minutes: road-use agreements, tax-abatement or economic-development agreements, and project presentations.
Municipal agendas where a project touches city jurisdiction, plus development agreements where used.
Groundwater conservation district records for wells and water use, and the county floodplain administrator and drainage records for grading and stormwater questions.

What these can establish: that identified instruments are recorded against identified parcels, and that identified agreements or agenda items exist. What they cannot establish: that construction is underway or that a facility operates — a recorded option can sit unexercised for years.

5. Environmental records

Where a project involves activities regulated by the Texas Commission on Environmental Quality — such as construction stormwater authorization or other permits — TCEQ’s public records and databases can show what authorizations exist for what site and holder. As with every source here, an authorization shows an authorization; it does not by itself establish construction progress or operation.

6. Transmission and grid records

A solar project may require separate transmission, substation, or interconnection facilities — generation-tie lines, upgraded utility lines, new or expanded substations — that are studied, approved, and in some cases certificated in their own proceedings and that can affect properties well outside the solar-site boundary. When researching a project, research its grid path too: PUCT dockets concerning related transmission facilities, ERCOT planning and interconnection materials, and recorded transmission easements in the county records along potential routes.

Use precise status labels — and only ones a source supports

One generic “solar farm” label hides exactly the information a landowner needs. When describing a project, use the most precise status the official record supports, such as: Proposed; Interconnection request submitted; Under ERCOT review; Approved for interconnection; PUCT-registered entity; Asset registered; Under construction; Commissioning; Operating; Delayed; Withdrawn; Canceled; or — honestly — Status not established by the reviewed records.

Do not infer “operating” from a company registration, a land lease, an option agreement, an ERCOT interconnection request, an application, a docket filing, a tax agreement, or a press announcement. None of those is an operating facility.

A statewide table — and why this page does not publish one today

Official-source extraction in progress — status reviewed July 22, 2026.

This page does not currently publish a project-by-project statewide table, because a reliable table must be populated entry-by-entry from official records — PUCT filings, ERCOT registration materials, and county records — with each row carrying its source, its supported status, and the date it was checked. We have not completed a verified official-source extraction, and we will not invent project names, locations, counties, capacities, or operating statuses to fill one. When entries are published, each will identify: the project or resource name; the registered entity; the county or officially identified area; the resource or filing type; the status supported by the source; the official source; the date last checked; and any important limitation. This page is a research directory and methodology — not a census of Texas solar projects — and it should never be read as a complete list.

Methodology for any entry published here

Any project entry added to this page will follow these rules: only official sources (PUCT, ERCOT, TCEQ, county, or other government records) may support an entry; every entry states the specific source and the date checked; every status uses the labels above and only as far as the cited source supports; conflicting or ambiguous records are described as such; and entries are re-verified before being restated. Accuracy is more important than list size.

Frequently asked questions

Is there one official map of all Texas solar farms? No single Texas database, by itself, establishes a complete statewide list. ERCOT publishes system-wide interconnection and resource information, the PUCT maintains filings and registrations, and counties hold the parcel-level instruments — each partial, each establishing only what it establishes.

A company registered with the PUCT says it has a project in my county. Is it operating? The registration establishes the company’s registration. Check ERCOT resource materials, county records, and — most directly — the ground. “Registered entity” and “operating facility” are different facts.

An interconnection request covers land near mine. Will it be built? Not necessarily. Requests are studied in volume and frequently withdrawn or changed. Watch for later-stage indicators — asset registration, recorded easements, county road-use agreements, construction permits — and even those do not guarantee completion.

How do I find who is behind a project LLC? Start with the entity name on recorded county instruments and PUCT/ERCOT filings; filings sometimes identify parent companies or affiliates. Corporate-family questions can require registered-agent and business-filing research, and the answer can change when projects are sold.

The key takeaway

Texas solar research is source discipline. The PUCT Interchange shows filings; PUCT directories show registered companies; ERCOT materials show where a project sits in the interconnection and registration pipeline; county records tie instruments to parcels; TCEQ records show environmental authorizations; and grid records show the transmission path. No one of them — and no press release — establishes that a project is operating.

Describe every project with the most precise status the official record supports, note what each source cannot establish, and treat “status not established by the reviewed records” as a legitimate, honest answer.
