Ellerslie Substation Expansion
What’s happening at the Ellerslie Substation? Project Area Update: July 2010
You may have noticed recently that construction activities are occurring near AltaLink’s Ellerslie Substation. This construction work is not associated with the Ellerslie Substation Expansion project which AltaLink has been conducting consultation about in the community over the past several weeks, a process that is nearly complete. Construction related to transmission infrastructure only occurs if approval is received from the AUC. AltaLink has yet not submitted its Facility Application for this project to the Alberta Utilities Commission (AUC), but anticipates doing so later in 2010. If the AUC approves the Ellerslie Substation Expansion project, construction is scheduled to begin in early 2012.
Construction activities you may be seeing right now in the Ellerslie Substation area are not directly related to the Ellerslie Substation Expansion project, but rather are other transmission infrastructure projects being built. All of the projects currently under construction have received the required AUC approval, including permit and license.

Proposed Project Details: January 2010
New transmission structures for 908L, 946L and 947L
AltaLink is proposing to build up to nine new transmission structures within AltaLink’s existing easement, including:
• up to three 240 kV three-pole tubular steel structures to connect 946L,947L, and 908L transmission lines to the south side of Ellerslie.
• up to six 240 kV monopole structures to connect 946L, 947L and 908L lines from the north side of Ellerslie to the east side of Ellerslie.
Substation Expansion
• Is situated so that the 500 kV Heartland transmission line (if the AU C approves the preferred East TUC
Route) can be moved further away from residences along the TUC.
• Up to nine new transmission structures.
• The existing fenced area will increase from 52,035 square metres to about 73,100 square metres.
