Lights only when needed: aircraft detection lighting for wind energy

How SkyGuard ADLS keeps turbine obstruction lights dark until an aircraft approaches, and what it takes to get FAA approval and community support.

For: Wind developers and operators, utility renewables teams, permitting and community relations

Summary

What the paper covers.

Blinking red obstruction lights are one of the most common community objections to wind farms. An ADLS keeps the lights off until an aircraft enters a defined volume around the project.

States are moving from encouraging ADLS to requiring it. The paper covers how ADLS works, why altitude matters, the FAA approval path and the benefits by stakeholder.

Recommendations

  • Plan ADLS at permitting, not as a retrofit
  • Choose 3D detection that measures altitude
  • Budget for the FAA process: tower determinations, ADLS approval and flight-check data
