Rules for New High-Voltage Power Lines and Advanced Technology

Last scannedAug 22, 2026, 4:24 AM

In one sentence

This law updates the definition of special power lines to include advanced technologies, requires companies building new high-voltage overhead lines to provide specific details in their applications, and asks the Public Service Commission to review certain evidence before approving these projects.

What it does

  • Updates the legal definition of a 'qualified generator lead line' to include associated advanced transmission technologies that support carrying electricity over 69,000 volts from out-of-state renewable sources.
  • Requires applicants seeking permission to build new overhead transmission lines to include specific information in their official applications.
  • Mandates the Public Service Commission to consider certain evidence before making a final decision on applications for high-voltage power line construction.
  • Defines 'advanced transmission technologies' as grid-enhancing tools, high-performance conductors, or energy storage used specifically for transmission purposes.

Who it affects

  • Electric companies and other entities seeking to build overhead transmission lines carrying more than 69,000 volts.
  • The Maryland Public Service Commission, which must review applications and evidence before issuing certificates of public convenience and necessity.
  • Owners or operators of existing overhead transmission lines who are required to submit certain reports.

Limits and unknowns

  • The provided text cuts off before listing the specific types of evidence applicants must include in their applications.
  • The full details regarding the reports that transmission line owners or operators must submit are not included in this excerpt.
  • This summary is based on a partial bill text and does not contain every section of the final law.

Terms to know

Advanced Transmission Technologies
Grid-enhancing technologies, high-performance conductors, or energy storage used as transmission.
Qualified Generator Lead Line
