Anita Patel Sonja Tessari Project Manager Project Delivery Transmission 2500, 330-5th Avenue SW (T) Anita.Patel@aeso.ca Sonja.Tessari@aeso.ca Project Benign Energy Heritage Wind Farm -Updated The proposed Heritage WAGF will be connected to the Alberta Interconnected Electric System ( AIES ) at the Fidler 312S substation in the Pincher Creek area. The windfarm is rated at 350 MW with 100 MW inservice at Stage 1 and 250MW at Stage 2. The Stage 1 development is dependent upon the completion of substation Fidler 312S for connection. The Stage 2 development is dependent upon the completion of transmission lines 1004L/992L from Fidler 312S to Chapel Rock 491S for connection. Under the current configuration, the wind power plant will consist of Vestas V90 3MW wind turbines. Both stages are onhold pending regulatory approval of Fidler 312S and transmission lines 1004L/992L. The reason for the staged approach is to inject as much as the system can handle without serious RAS constraints prior to the approval and completion of the Chapel Rock substation (connection to the 500kV Page 15

19 line). After the Chapel Rock Substation is built the system in the Pincher Creek area will become unconstrained (mostly) and will be able to handle the full projected output of the Heritage Windfarm. The requested In Service Date ( ISD ) for Stages 1 & 2 development is September 2013 are on-hold and September 2014 for Stage 2.
