What energy projects are proposed in La Salle County?

ERCOT's September 2026 interconnection report lists 5 proposed energy projects in La Salle County (2 solar, 1 wind and 2 battery storage), about 1,499 MW in all. 2 of the 5 have a signed interconnection agreement.

What stands out in La Salle County

By capacity, solar leads in La Salle County with 716 MW across 2 projects, followed by battery storage (2 projects, 586 MW) and wind (1 project, 197 MW). The largest single project is La Salle Solar, a 513 MW solar project listed under La Salle Solar LLC, with its agreement signed and security posted, and its target online date is Sep 2028. Of the 5, 3 are still in ERCOT's study process, 1 has a signed interconnection agreement but no security posted yet and 1 has posted security or started construction. Connection points are mostly at 138 kV (3 projects) and 345 kV (2 projects) (why the voltage matters). Each of the 5 projects is listed under a different company. Target online dates for the projects not yet running span Dec 2026 to Sep 2028. All of them fall in ERCOT's South load zone. 2 that were listed in August have since dropped off.

A listing is a request to study a grid connection, not a built project; the stage column says how far each one has gone.

Stage, most advanced first: Approved for synchronization (first power) · Approved for energization (backfeed) · Under construction · Signed; security posted (interconnection agreement signed and financial security posted) · Signed (agreement signed, security not yet posted) · In study (screening or full interconnection study, no agreement). A target date that has already passed is marked; ERCOT keeps the developer's last reported date until the developer changes it.

No longer listed since August

These projects were in ERCOT's August interconnection report but are not in its September 2026 report. ERCOT's reports do not say why a project leaves the list.

Crowded connection points in La Salle County

Substations and switching stations named by two or more of the county's requests, matched on ERCOT's PSS/E bus number rather than the exact wording, so "60404 SOLSTICE", "AEP Solstice Substation #60404" and a tap off the Solstice line count together. Every request statewide that names the bus is listed; a request on a tap line counts toward both ends. Sharing a bus is not the same as sharing a study group, and ERCOT decides the latter.

What the stages and dates mean: how to read ERCOT's report. ERCOT's report lists self-limiting facilities (batteries that limit injection below nameplate) at 0 MW; repowers of existing plants show 0 with no capacity change. "Approved for energization" and "approved for synchronization" are ERCOT's own milestones (backfeed, then first power). "Shared with N other requests" counts active requests anywhere in ERCOT naming the same point of interconnection, matched on ERCOT's exact wording, so a bus written two ways counts as two points.

Permits and reviews for La Salle County

Texas has no state siting permit for solar or wind, and Texas counties generally have no zoning authority, so a project in La Salle County is shaped by site control, the county road use agreement, tax agreements, and the grid connection (what still applies · the twelve approvals, stage by stage). Wetland, endangered species, historic, and FAA reviews depend on the site: statewide and federal contacts · decommissioning law.

How a project in La Salle County connects to the grid

La Salle County is on the ERCOT grid. The projects listed above are in ERCOT's South load zone. The serving utility handles the connection request. Interconnection by market and utility · what ERCOT is.

How long it takes. ERCOT staff put the connection process at 18 to 30 months for generation of 10 MW or more, before construction or supply delays (ERCOT, Oct. 2024). Across the U.S., the median project built in 2025 took 61 months from interconnection request to commercial operation (Berkeley Lab, Queued Up 2026), so a lease signed today usually means construction years out: timelines by market.
