What’s the difference?

EnergyLines March 2019

 

Transmission and distribution power lines are a vital part of “the grid.” These lines incorporate separate voltages as power is transmitted from generating stations to member-consumers.

 

Distribution lines:

  • These lines and equipment are owned by member co-ops who deliver energy to member-consumers.
  • The most common voltage of distribution lines is 12,470 kV.
  • These lines are often found overhead but are sometimes located underground.

 

Transmission lines:

  • Transmission lines and equipment are used to transmit energy from generating facilities to primary substations.
  • Transmission lines are installed on larger structures than distribution lines.
  • Transmission voltages in use by Hoosier Energy range from 69kV to 345kV.
