APPENDIX D AESO PARTICIPANT INVOLVEMENT PROGRAM

138 kV Transmission System Reinforcement in Downtown Needs Identification Document

1.0 Participant Involvement Program

From August 2014 to November 2015, the AESO conducted a Participant Involvement Program (“PIP”) to assist in preparing its 138 kV Transmission System Reinforcement in Downtown Calgary Needs Identification Document (“Application”) in accordance with the requirements of NID14 and Appendix A2 of Utilities Commission Rule 007: Applications for Power Plants, Substations, Transmission Lines, Industrial System Designations and Hydro Developments.

1.1 Stakeholder Notification

The AESO’s PIP was designed to notify and provide information to stakeholders in the area where the AESO determined that transmission facilities could be installed to implement the AESO’s preferred option to meet the identified need (“Notification Area”). Specifically, occupants, residents and landowners within the Notification Area, as well as the following government bodies, agencies and other stakeholder groups were notified by the AESO (collectively, “Stakeholders”):1

 MLA, Honourable Jonathon Denis,  Councillor Peter Demong, Ward 14 Calgary-Acadia (August 2014 Newsletter)  Fort Calgary  MLA, Ms. Brandy Payne, Calgary-Acadia  Calgary Stampede (October 2015 Newsletter)  Prince’s Island Park  MLA, Kent Hehr Calgary Buffalo  Calgary Chamber of Commerce (August 2014 Newsletter)  Calgary Downtown Association  MLA, Honourable ,  Cliff Bungalow - Mission Community Calgary-Buffalo (October 2015 Association Newsletter)  Beltline Community Association  MLA, Wayne Cao Calgary-Fort  Downtown Commercial Core Community (August 2014 Newsletter) Association  MLA, Honourable , Calgary-Fort  Downtown West Community Association (October 2015 Newsletter)  Downtown East Village Community  Councillor Druh Farrell, Ward 7 Association  Councillor Evan Woolley, Ward 8  Eau Claire Community Association  Councillor Gian-Carlo Carra, Ward 9  Erlton Community Association

1.1.1 AESO Newsletters

In August 2014, the AESO mailed its newsletter titled Downtown Calgary Transmission Reinforcement through direct unaddressed mail via postal code to all occupants, residents and landowners in the Notification Area. Additionally, the AESO mailed this newsletter directly to the government agencies and other organizations listed in Section 1.1.2 The newsletter was also posted to the AESO website at www.aeso.ca/downtowncalgary and a notice was published in the AESO Stakeholder Newsletter3 on August 19, 2014. Copies of the newsletter and the AESO Stakeholder Newsletter posting are included in Attachments 1 and 2, respectively.

In October 2015, the AESO issued a Stakeholder Update newsletter, titled Downtown Calgary Transmission Reinforcement - Stakeholder Update, to notify the Stakeholders of its revised preferred option to use a lower voltage, 138 kV instead of 240 kV, transmission line to address the identified need. The Notification Area was unaffected by the changes in the AESO’s preferred option. On October 9, 2015, this newsletter was mailed to all occupants, residents and landowners in the Notification Area through direct unaddressed mail via postal code. Further, the AESO mailed the newsletter directly to the government agencies and other organizations listed in Section 1.14, as well as to everyone who had requested to be kept informed following the notification mailed in August 2014. The newsletter was posted to the AESO website at www.aeso.ca/downtowncalgary on October 13, 2015, and a notice was published in the AESO Stakeholder Newsletter on October 20, 2015. Copies of the newsletter and the

PAGE 3 How does the AESO determine the need for transmission development?

Alberta’s growing population and expanding industry are driving an increasing demand for power.

Power generation developers are planning and building new power plants to meet this demand. The transmission system must have enough capacity to transmit power from where it is generated to where it will be used.

The AESO forecasts both demand from consumers and supply from generators. We study the location and amount of new generation and growing demand and develop plans to ensure Albertans continue receiving reliable power.

Transmission reinforcement is required to accommodate forecast growth and increase reliability of the power supply into the area. Between August 2014 and November 2015, the AESO noti!ed stakeholders, including residents, occupants and landowners, regarding the need for the proposed transmission system reinforcement, and its intention to apply to the AUC for approval of the NID. Once !led, the NID will be posted on the AESO website at www.aeso.ca/downtowncalgary Please visit www.aeso.ca for more information or contact the AESO at 1-888-866-2959 or [email protected].

The shaded area in the map indicates the approximate area where transmission system reinforcement is needed. Existing substations where modi!cations are required are also shown. In a separate application called a Facilities Application, ENMAX Power Corporation, the transmission facilities owner (TFO) in the area, will describe the speci!c routes they propose to implement the transmission system reinforcement, and request AUC approval to construct and operate the speci!c transmission facilities.

1456 November 2015 Downtown Calgary Transmission Reinforcement – Public Notification of Regulatory Filing As downtown Calgary continues to develop and grow, future demand for electricity is forecast to rise beyond the capability of the existing downtown Calgary transmission system. The existing transmission system in downtown Calgary can become overloaded under certain conditions. The AESO has therefore identified the need for transmission reinforcement in the downtown area. The AESO is proposing to develop additional transmission capacity, a new 138kV transmission line, between the existing ENMAX No.8 and ENMAX No.2 Substations and associated modifications at these substations.

The AESO intends to file the Downtown Calgary Transmission Reinforcement Needs Identification Document (NID) application with the Alberta Utilities Commission (AUC) on or after November 18, 2015, and will be requesting that the AUC approve this NID.

The AESO has posted its public notification advertisement for its NID filing on its website for the Downtown Calgary Transmission Reinforcement. Please click here to view the advertisement or visit the AESO website at www.aeso.ca/downtowncalgary to see all the relevant documents including the NID application once it is filed with the AUC.
