What energy projects are proposed in Bexar County?
ERCOT's September 2026 interconnection report lists 23 proposed energy projects in Bexar County (1 solar, 20 battery storage and 2 gas), about 5,170 MW in all. 10 of the 23 have a signed interconnection agreement, and 4 have been approved for energization or synchronization.
What stands out in Bexar County
By capacity, battery storage leads in Bexar County with 4,983 MW across 20 projects, followed by solar (1 project, 152 MW) and gas (2 projects, 34 MW). The largest single project is Howard Road BESS, a 618 MW stand-alone battery storage project listed under Project Fast Flow LLC, still in study, and its target online date is Apr 2028. Of the 23, 13 are still in ERCOT's study process, 3 have a signed interconnection agreement but no security posted yet, 3 have posted security or started construction and 4 are approved for energization or synchronization. Connection points are mostly at 138 kV (15 projects) and 345 kV (7 projects) (why the voltage matters). CPS Energy and Mission Station LLC are each listed on 2 projects; 21 different companies appear in all. Target online dates for the projects not yet running span Apr 2027 to Feb 2031. All of them fall in ERCOT's South load zone.
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.

Crowded connection points in Bexar 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 Bexar County
Texas has no state siting permit for solar or wind, and Texas counties generally have no zoning authority, so a project in Bexar 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.
Local action: as of October 17, 2026, we found no 2024–2026 commissioners court action on solar, wind, or battery storage posted on Bexar County's website or reported by local news. Counties act mostly through tax abatement and road use agreements, so ask the county judge's office whether any are pending.
How a project in Bexar County connects to the grid
Bexar 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.
