Edmonton to Calgary Transmission Reinforcement
The AESO has identified the need for two HVDC transmission lines between Edmonton and Calgary. AltaLink will build one line located on the west/centre portion of the province, connecting the existing Wabamun Lake hub west of Edmonton to the Calgary area hub near Langdon. ATCO Electric will build one line located on the eastern side of the province connecting the Heartland hub northeast of Edmonton to a southern hub in the Brooks area.

On November 20, 2008 the AESO updated the poster boards being used at Open Houses throughout central Alberta. The updates reflect clarifications from the poster boards last updated July 19, 2008 based on reviews and comments at Open Houses. The changes are as follows:
Page 11 - the display of transmission towers has been adjusted to more accurately reflect comparative sizes
Pages 13 through 23 - present 11 high level geographic concepts for transmission reinforcement with an expanded study area further west and further east than previously considered. The blue swaths representing the following concepts have not changed though they are now situated within the wider study area:
- West Concept
- Centre Concept
- Centre-East Concept
- Heartland Concept
The following concepts are new and were not previously considered by the AESO:
- West 2 Concept
- Centre-East 2 Concept
- Centre-East 3 Concept
- Centre-East 4 Concept
- East 2 Concept
- East 3 Concept
- East 4 Concept
Page 24 - The Geographic Options table compares the Concepts outlined in the maps on pages 13 - 23. Additional columns have been added to provide data metric comparisons for the additional Concepts being considered. In addition the following changes have been made:
- The metrics used in previous poster boards to compare the West, Centre, Centre-East and East Concepts have changed slightly as a result of closer scrutiny to data collected through Geographic Information Systems;
- Poster boards used previously, and posted to the AESO web site August 25, 2008 outlined data metrics for "Landowners engaged by future TFO Routing." This comparison has been deleted from consideration in comparing geographic options. The data was originally derived from average County populations but did not consider the potential for different population densities in different quadrants of a County. The metric, therefore, did not reveal the number of landowners that may be engaged by future routing considerations;
- In the West Concept, "Residences within 150m of centre line" changed from 30-60 to 30-40 as a result of a correction to a representative greenfield route that should have avoided a community;
- Data used for the comparison "Proximity to Historical Resources in or within 800 m..." has changed in part as a result of an updated database provided by Alberta Culture and Community Spirit
Metrics which did not change at all are:
- Major River Crossings;
- Distance Across Treed Areas > 100 hectares (km);
- Proximity to Recreational Areas in or within 800m if R-O-W (#); and
- Proximity to Protected or Provincially Designated Environmentally Sensitive Areas in or within 800 m of R-O-W.
In the "West" the following did not change:
- Agriculture;
- Native Grassland crossed (ha)
- Sensitive Westland Areas (ha) in or within 800m of R-O-W;
- Opportunity to Parallel Existing Transmission Lines (km); and
- Proximity to Historical Resources in or within 800m of R-O-W.
In the East, the following did not change:
- Cultivated Land Crossed (km)

On July 19, 2008, the AESO updated the poster boards being used at Open Houses throughout Alberta. The updates reflect clarifications from the original versions posted June 2, 2008 based on reviews and comments at Open Houses. The changes are as follows:
Page 7 - The wording in the diagram illustrating the regulatory process has been revised to clarify the AESO's Needs Identification Document submission requires approval of the Alberta Utilities Commission.
Pages 15 to 18 - The maps showing the geographic concepts have been updated to clarify the nature of the existing transmission lines - double circuit lines are identified with a diamond, single circuit with a circle.
Page 18 - The map showing the East Concept has been updated to clarify the area to the west of Sherwood Park.
Pages 21 to 23 - The diagrams of the concepts in existing and new paths have been rearranged to clarify the concepts and options.
