To connect the proposed wind project to the grid, Piikani Resource Development Ltd. plans to construct a new
substation, named Piikani 1149S Substation.

To accommodate the project, AltaLink is proposing to:

• construct approximately 10 km of new 138 kilovolt (kV) transmission line along
  one of two potential routes from PRDL’s proposed Piikani 1149S Substation to
  AltaLink’s existing Windy Flats 138S Substation
• install two new 138 kV circuit breakers and associated equipment at the Windy
  Flats 138S Substation
• install optical grounding wire (OPGW) between PRDL’s proposed Piikani 1149S
  Substation and AltaLink’s existing Windy Flats 138S Substation
