Site screening

Solar Transmission Line Proximity Screening

Screen transmission-line context, voltage, crossing exposure and connection-route implications for a solar project.

Why this workflow matters

Transmission-line proximity can indicate network context but also create easements, clearances and crossing constraints. The same mapped line may be an opportunity, a site constraint or irrelevant to the intended connection.

Questions to answer

  • What voltage and ownership are recorded?
  • Does the line cross or merely pass near the site?
  • Which statutory clearances or easements apply?
  • Would connection require a new switching station?

Recommended workflow

  1. 1Classify nearby lines by voltage and data confidence.
  2. 2Measure intersection and minimum distance to the site.
  3. 3Map potential easements, crossings and compound requirements.
  4. 4Confirm the connection concept with the asset owner.

Evidence to collect

  • Line geometry and voltage attributes
  • Easement or wayleave information
  • Site and route survey
  • Network connection concept

Decision-ready outputs

  • Line-proximity schedule
  • Crossing and clearance constraints
  • Connection-concept questions
