Sample brief: 200 MW solar in Texas

Outcome

• 0 meet every known requirement
• 469 need more information
• 117,212 excluded: they fail at least one must-have

No site is counted as meeting the requirements while a must-have is unresolved.

Shortlist

Match to default solar + storage profile. Ranked by match within "Needs more information". A match is not a Voltane score, and it never outranks a must-have.

   • ✓ Pass Site size: 2,110 ac meets the 1,000 ac minimum
   • ✓ Pass EHV line (345 / 380 kV+): 1.2 mi is within the 2 mi maximum
   • ✓ Pass Queue MW within 10 mi: 0 MW is within the 500 MW maximum
   • ✓ Pass Federal land: no (required: no)
   • ✓ Pass Indicative size: 419 MW (indicative, basis unconfirmed (DC/AC)) meets the 200 MW minimum
   • ? Unknown Interconnection capacity at the point of interconnection: not screened (No public dataset states it; distance to a line is not a connection. An ERCOT interconnection study is needed.)

Next checks

1. Pull the official county record for each shortlisted site (the property ID and record link are in its site panel) and confirm ownership, boundaries and current use.
2. Ask the utility or grid operator for a pre-application or feasibility review: distance to a line or substation is not interconnection, and queue figures are a competition proxy only.
3. Check county and municipal rules for the technology (local restrictions are listed in each site panel where known).
4. Voltane takes no action with outside parties: any contact with landowners, utilities or agencies is yours to make.

Requirements as screened

• Screened Site size (total acres): at least 1,000 ac
• Screened Distance to an extra-high-voltage line (345 kV+): at most 2 mi
• Screened Interconnection-queue MW within 10 mi: at most 500 MW
• Screened Overlaps federal or military land: equal to no
• Screened Indicative project size: at least 200 MW
• ? Unknown Interconnection capacity at the point of interconnection: must-have, not screened (No public dataset states it; distance to a line is not a connection. An ERCOT interconnection study is needed.)

Added from the target size: Your 200 MW project size → requires an indicative size of at least 200 MW (largest contiguous buildable block ÷ 4.25 ac/MW; indicative, basis unconfirmed (DC/AC)). Sites whose buildable block holds less than 200 MW are excluded.

• Interconnection-queue MW within 10 mi. Competition proxy only: queued MW located near the site, not a measure of grid headroom; requests that could not be located are not counted, so 0 MW is not "no competition".
• Indicative project size. Indicative, basis unconfirmed (DC/AC): largest contiguous buildable block ÷ 4.25 ac/MW.

Each result is a parcel-level site from county parcel data. Texas: the map serves 333,870 sites; 117,681 pass every map exclusion (the map's count with every exclusion on and no other filter). This brief read 117,681 — the same sites. Sites failing an exclusion are not screened here. Record read: 117,681 of 117,681 sites joined to their county record (234 county files). Screened in your geography: 117,681 of 117,681 sites read = 0 meet + 469 need more information + 117,212 excluded.

Preliminary screening only: not an engineering study, interconnection study, permit, or guarantee. Screening only — not a site suitability determination.
