The Alberta Electric System Operator (AESO) has requested that AltaLink modify portions of the existing 853L transmission line to increase electricity capacity and meet the growing demands for electricity in the area.

The 853L transmission line is a single circuit 138 kilovolt (kV) line, located approximately six kilometres west of the City of Brooks, in the County of Newell. To increase the electricity capacity on the 853L transmission line, the proposed project includes:

  • replacing the conductor on an approximately 17.5 kilometre segment of the transmission line that starts at the West Brooks Substation (located in NW-28-18-15 W4M)
  • replacing 13 structures and modifying two other structures along the 853L transmission line
  • building two temporary transmission lines during construction to ensure customers in the area continue to receive reliable electricity service
