Greengate Blackspring Ridge I wind farm 2 Projects in Construction The following projects have been approved by the Alberta Utilities Commission at both the need, facilities and routing stages with construction set to begin or on-going. 2.1 System Projects 2.1.1 Project 786 - Edmonton Region 240kV Line Upgrades – Updated The majority of this project has been completed: • Increase the capacity of 908L and 909L up to the summer rating of the primary conductor (2 x 477 kcmil) by replacing the conductor on the small conductor section (first 4 km of line east of Sundance 310P) • Increase the capacity rating of 902L up to the summer rating of the primary conductor (2 x 477kcmil) by replacing the conductor on the small conductor sections of 902L (first 4 km of line east of Wabamun 19S and first 4 km of line east of Sundance 310P) • Construct 12 km of new double circuit 240 kV line with one side strung east from Keephills 320P to the 904L-908L-909L confluence point west of Stony Plain in order to move the termination point of 908L from Sundance 310P to Keephills 320P, and add two associated 240 kV breakers at Keephills 320P • Swap the connections of 904L and 908L at the 904L-908L-909L confluence point south of Jasper 805S in order to move the termination point of 904L from Wabamun 19S to Sundance 310P • Install Special Protection Systems (SPS) for three double circuit tower failure events (Category C5) • Install a 240 kV 600 MVA phase shifting transformer in 9L57 line and three associated 240 kV breakers; preferred location is the proposed Livock station north of Brintnell. The following components of the project are not yet completed construction due to continued negotiations with land owners: • Rebuild the 41 km east-west single circuit wood pole sections of 904L (Jasper to Wabamun) using 2 x 1033 kcmil conductor. On-going negotiations with land owners in the area has delayed completing this work. • Rebuild the 6 km east-west single circuit wood pole section of 904L (Jasper to Petrolia) using 2 x 1033 kcmil conductor. On-going negotiations with land owners in the area has delayed completing this work. • Increase the capacity of both 904L sections out of Jasper 805S up to the summer rating of the primary conductor (2 x 477 kcmil) by replacing the conductor on the small conductor section (12 km of line south of Jasper 805S). The project is under construction and the current expected in service date is end of January 2016.

This project consists of the following lines: • 911L replaced by Foothills to Peigan 240 kV double circuit transmission line with 50% series compensation. Each circuit rated with a summer/winter capacity of approximately 980/980 MVA. (Under construction) • A new 240 kV double circuit line, approximately 150 km in length from Cassils (near West Brooks) to Bowmanton (East Medicine Hat). Each circuit is rated at a summer/winter capacity of approximately 980/980 MVA. (Commissioned) • A new 240 kV switching station at a location known as Milo Junction and converting the two existing three terminal Langdon - West Brooks - North Lethbridge lines into six two-terminal lines. (Commissioned) • A new 240 kV double circuit line, approximately 80 km in length from Bowmanton (Medicine Hat) to Whitla connecting the wind farms in the south. Each circuit is rated at a summer/winter capacity of approximately 980/980 MVA. (Commissioned) • New Chapel Rock 500/240 kV substation cut into existing 1201L. The station will include two 1200 MVA 500/240 kV transformers, two 240 kV 100 MVAr capacitor banks and a +200/-100 MVAr SVC and one 45 MVAr shunt reactor. • New Chapel Rock – Castle Rock Ridge - Goose Lake 240 kV double circuit transmission line with a rated summer/winter capacity of approximately 980/1200 MVA. • Add a 138 kV phase shifting transformer between Coleman and Pincher Creek. (Commissioned) • New Ware Junction – Langdon 240 kV double circuit transmission line with a rated summer/winter capacity of 980/1200 MVA with 50% series compensation. (Cancelled) • The addition of two (2) 240/138kV 400MVA transformers at new Windy Flats station near existing Peigan 59S station. (Under construction) • New 240 kV Etzikom Coulee substation to connect future wind farms. (On hold) • Interconnect Etzikom Coulee with Picture Butte (MATL) substation. (On hold) • Interconnect Etzikom Coulee with Goose Lake. (On hold) Page 2 The project is expected to be operational by 2016 except for those
