Page 1 June, 2016

Executive Summary

Project Overview

Trans Mountain Pipeline L.P. (TMPL) submitted a System Access Service Request (SASR) to the Alberta Electric System Operator (AESO) to supply electricity to a proposed industrial load addition in the Gainford area.

The SASR includes a request for a Rate DTS, Demand Transmission Service, contract capacity increase from 3.5 MW to 14.5 MW for the system access service provided at the existing Gainford 165S substation, and a request for transmission development (collectively, the Project). Specifically, TMPL requested an upgrade to the existing Gainford 165S substation to support the increased demand at the Gainford Pump Station for Kinder Morgan Canada’s proposed Trans Mountain Expansion Project.

The scheduled in-service date for the Project is February 1, 2019.

This report details the system performance studies undertaken to assess the impact of the Project on the Alberta interconnected electric system (AIES).

Existing System

Geographically, the Project is located in the AESO planning area of Wabamun (Area 40), which is part of the AESO Edmonton Planning Region. The Wabamun area is surrounded by the Edmonton (Area 60), Athabasca/Lac La Biche (Area 27), Swan Hills (Area 26), Hinton/Edson (Area 29), Drayton Valley (Area 30), and Wetaskiwin (Area 31) planning areas.

From an electrical system perspective, there is a significant amount of base-load coal-fired generation in the Wabamun area. The transmission system is comprised of 500 kV, 240 kV, 138 kV and 69 kV facilities. The Wabamun area (Area 40) is connected to the rest of the AIES by:

500 kV transmission lines 1325L, 1202L and 1209L;

240 kV transmission lines 973L, 974L, 1043L, 903L, 190L, 905L, 922L, 926L, 919L, 989L, 1045L, 909L and 913L; and,

138 kV lines 834L, 744L, 799L, 672L, 723L, 452L, and 7L230.

The Gainford 165S substation has a T-tap connection onto the 138 kV transmission line 156L (Wabamun 19S – Entwistle 235S) through the 138 kV transmission line 156BL.

The existing constraints in the Edmonton Region are managed in accordance with the procedures set out in Section 302.1 of the ISO rules, Real Time Transmission Constraint Management. Automatic protection schemes are also presently used to manage thermal and transient stability violations in the Edmonton Region.

Study Summary

Study Area for the Project

The study area for the project consists of the Wabamun area (Area 40). The study area also includes the transmission lines connecting the Wabamun planning area to neighboring planning areas. All transmission facilities within the study area were studied and monitored to assess the

impact of the Project on the AIES, including any violations of the Reliability Criteria (as defined in Section 2.1.1).

Studies Performed for the Project

Power flow analysis was performed for the 2016-2017 winter peak (WP) and 2017 summer peak (SP) pre-Project and post-Project scenarios. Voltage stability analysis was performed for the 2016-2017 WP post-Project scenario.

Results of the pre-Project Studies

No Reliability Criteria violations were observed for any of the pre-Project study scenarios.

Connection alternatives examined for the Project

The AESO examined two transmission alternatives to meet TMPL’s request for system access service:

Alternative 1: Upgrade the existing Gainford 165S substation by adding a second 138/4.16 kV transformer, with a rating of 15/20/25 MVA, and other associated equipment. Alternative 1 would require upgrading the existing 138 kV bus and the existing 4.16 kV bus, to facilitate the connection of the existing and new transformers. In addition, the substation fence would need to be expanded to accommodate the second transformer.

Alternative 2: Upgrade the existing Gainford 165S substation by replacing the existing 7.5/8.4 MVA, 138/4.16 kV transformer with a new 15/20/25 MVA, 138/4.16 kV transformer and adding other associated equipment. Alternative 2 would also require upgrading the existing 138 kV bus and the existing 4.16 kV bus, but fewer upgrades at both busses than necessary for Alternative 1, to facilitate the connection of the new transformer.

Connection alternatives selected for further examination

Alternative 2 was selected for further study. Alternative 1 involves additional transmission facilities and hence, additional cost compared to Alternative 2. Similar to Alternative 2, Alternative 1 requires upgrades to the existing 138 kV bus and the existing 4.16 kV bus; however, the scope of bus upgrades required for Alternative 1 would be greater than for Alternative 2. Further, Alternative 1 requires expansion of the substation fence to accommodate the second transformer. Therefore, Alternative 1 was not selected for further study.

Results of the post-Project studies

Similar to the pre-Project power flow scenarios, no thermal or voltage violations were observed for Category A conditions and Category B contingency conditions in any of the post-Project power flow scenarios. Voltage stability analysis was also performed. No violation of the voltage stability criteria was observed subsequent to the connection of the Project using Alternative 2.

Conclusions and Recommendation

Based on the study results, Alternative 2 is technically viable. The studies show that the connection of the Project using Alternative 2 would not adversely impact the performance of the AIES. Therefore, it is recommended to proceed with the Project using Alternative 2 as the preferred option to respond to TMPL’s request for system access service.

1. Introduction

This Customer Connection Engineering Study Report presents the results of the study conducted to assess the impact of the Project (as defined below) on the performance of the Alberta interconnected electric system (AIES).

1.1. Project

1.1.1. Project Overview

Trans Mountain Pipeline L.P. (TMPL) submitted a System Access Service Request (SASR) to the Alberta Electric System Operator (AESO) to supply electricity to a proposed industrial load addition in the Gainford area.

The SASR includes a request for a Rate DTS, Demand Transmission Service, contract capacity increase from 3.5 MW to 14.5 MW for the system access service provided at the existing Gainford 165S substation, and a request for transmission development (collectively, the Project). Specifically, TMPL requested an upgrade to the existing Gainford 165S substation to support the increased demand at the Gainford Pump Station for Kinder Morgan Canada’s proposed Trans Mountain Expansion Project.

The scheduled in-service date (ISD) for the Project is February 1, 2019.

1.1.2. Load Component

The existing Rate DTS contract capacity for the system access service provided at the existing Gainford 165S substation is 3.5 MW. TMPL has requested a Rate DTS contract capacity increase to 14.5 MW.

The new load at the Gainford Pump Station consists of three 5000 HP induction motors. One Variable Frequency Drive (VFD) will be used to start the motors one at a time. In an emergency, the motors may be started across-the-line (without the VFD).

This connection assessment assumed a 0.9 lagging power factor (pf) for the load associated with the Project.

TMPL has not indicated plans for a future load increase requiring service from the Gainford 165S substation in the SASR.

1.1.3. Generation Component

There is no generation component associated with the Project.

1.2. Study Scope

1.2.1. Study Objectives

The objectives of the study are the following:

Assess the impact of the Project on the performance of the AIES.

Identify any violations of the relevant criteria, standards or requirements of the AESO, both before and after connection of the Project.

Recommend mitigation measures, if required, to enable the reliable connection of the Project to the AIES.

1.2.2. Study Area

1.2.2.1. Study Area Description

Geographically, the Project is located in the AESO planning area of Wabamun (Area 40), which is part of the AESO Edmonton Planning Region. The Wabamun area is surrounded by the Edmonton (Area 60), Athabasca/Lac La Biche (Area 27), Swan Hills (Area 26), Hinton/Edson (Area 29), Drayton Valley (Area 30), and Wetaskiwin (Area 31) planning areas.

From an electrical system perspective, there is a significant amount of base-load coal-fired generation in the Wabamun area. The transmission system is comprised of 500 kV, 240 kV, 138 kV and 69 kV facilities. The Wabamun area (Area 40) is connected to the rest of the AIES by:

500 kV transmission lines 1325L, 1202L and 1209L;

240 kV transmission lines 973L, 974L, 1043L, 903L, 190L, 905L, 922L, 926L, 919L, 989L, 1045L, 909L and 913L; and,

138 kV lines 834L, 744L, 799L, 672L, 723L, 452L, and 7L230.

The Gainford 165S substation has a T-tap connection onto the 138 kV transmission line 156L (Wabamun 19S – Entwistle 235S) through the 138 kV transmission line 156BL.

The study area for the project consists of the Wabamun area (Area 40). The study area also includes the transmission lines connecting the Wabamun planning area to neighboring planning areas. All transmission facilities within the study area were studied and monitored to assess the impact of the Project on the AIES, including any violations of the Reliability Criteria (as defined in Section 2.1.1).

Figure 1-1 shows the existing transmission system in the study area.

2. Criteria, System Data, and Study Assumptions

2.1. Criteria, Standards, and Requirements

2.1.1. Transmission Planning Standards and Reliability Criteria

The Transmission Planning (TPL) Standards, which are included in the Alberta Reliability Standards, and the AESO’s Transmission Planning Criteria – Basis and Assumptions (collectively, the Reliability Criteria) 3 were applied to evaluate system performance under Category A system conditions (i.e., all elements in-service) and following Category B contingencies (i.e., single element outage), prior to and following the studied alternatives. Below is a summary of Category A and Category B system conditions as well as a summary of Category C5 system conditions.

Category A, often referred to as the N-0 condition, represents a normal system with no contingencies and all facilities in service. Under this condition, the system must be able to supply all firm load and firm transfers to other areas. All equipment must operate within its applicable rating, voltages must be within their applicable range, and the system must be stable with no cascading outages.

Category B events, often referred to as an N-1 or N-G-1 with the most critical generator out of service, result in the loss of any single specified system element under specified fault conditions with normal clearing. These elements are a generator, a transmission circuit, a transformer, or a single pole of a DC transmission line. The acceptable impact on the system is the same as Category A. Planned or controlled interruptions of electric supply to radial customers or some local network customers, connected to or supplied by the faulted element or by the affected area, may occur in certain areas without impacting the overall reliability of the interconnected transmission systems. To prepare for the next contingency, system adjustments are permitted, including curtailments of contracted firm (non-recallable reserved) transmission service electric power transfers.

The TPL standards, TPL-001-AB-0 and TPL-002-AB-0, have referenced Applicable Ratings when specifying the required system performance under Category A and Category B events, respectively. For the purpose of applying the TPL standards to the studies documented in this report, Applicable Ratings are defined as follows:

Seasonal continuous thermal rating of the line’s loading limits.

Highest specified loading limits for transformers.

For Category A conditions: Voltage range under normal operating condition should

follow the AESO Information Document ID# 2010-007RS. For the busses not listed in

ID#2010-007RS, Table 2-1 in the Reliability Criteria applies.

2.1.2. AESO Rules

AESO Information document ID# 2010-007RS, General Operating Practices - Voltage Control, which relates to Section 304.4 of the ISO rules, Maintaining Network Voltage, was applied to establish system normal (i.e., pre-contingency) voltage profiles in the study area and its vicinity. The TCM Rule will be followed in setting up the study scenarios and assessment of the impact of the Project connection. In addition, due regard will be given to the AESO’s Connection Study Requirements and the AESO’s Generation and Load Interconnection Standard.

The Reliability Criteria is the basis for planning the AIES. The transmission system will normally be designed to meet or exceed the Reliability Criteria under credible worst-case loading and generation conditions.

2.2. Study Scenarios

Table 2.2-1 summarizes the study scenarios used for the connection assessment. This connection assessment will assume a 0.9 lagging power factor (pf) for the load associated with the Project. Scenarios 1 and 2 are the pre-Project scenarios for 2016-2017 WP and 2017 SP, respectively and Scenarios 3 and 4 are the post-Project scenarios for 2016-2017 WP and 2017 SP, respectively. A power factor of 0.9 lagging was used for the new Project load.

2.3.3. Intertie Flow Assumptions

The Alberta-BC, Alberta-Montana, and Alberta-Saskatchewan intertie points are deemed to be too far away to have any material impact on the connection assessment for the Project. Therefore, the intertie assumptions are kept consistent with that in the corresponding AESO planning base cases and not adjusted in the study scenarios.

2.3.4. HVDC Power Order Assumptions

The flows in the Study Area are not significantly influenced by the AIES Western Alberta Transmission Line (WATL) and Eastern Alberta Transmission Line (EATL) HVDC facilities. Hence, the HVDC power order assumptions were kept consistent with that in the corresponding AESO planning base cases and not adjusted in the study scenarios.

2.4. System Projects

Table 2.4-1 lists the South and West of Edmonton Area Transmission Development subprojects that have been included in this study. Other than the South and West of Edmonton Area Transmission Development subprojects, no additional system projects were included in the study scenarios.

2.7. Voltage Profile Assumptions

The AESO Voltage Control Practice ID # 2010-007RS is used to establish normal system (i.e., pre-contingency) voltage profiles for key area buses prior to commencing any studies. Table 2-1 of the Reliability Criteria applies for all the buses not included in the ID # 2010-007RS. These voltages were utilized to set the voltage profile in the study scenarios prior to conducting power flow analysis.

3.1. Connection Studies Carried Out

The studies that were carried out for this connection assessment are identified in

Table 3.1-1:

Table 3.1-1: Summary of Studies Performed

System Conditions Power Flow7

Voltage Stability

1 2016-2017 WP Pre-Project 3.5 Category A and Category B Yes No

2 2017 SP Pre-Project 3.5 Category A and Category B Yes No

3 2016-2017 WP Post-Project 14.5 Category A and Category B Yes Yes

4 2017 SP Post-Project 14.5 Category A and Category B Yes No

3.2. Power Flow Analysis

The purpose of the power flow analysis is to quantify any incremental violations in the study area after the Project is connected. Power flow analysis was completed for all study scenarios to identify thermal overloads or voltage violations as per the Reliability Criteria, and to identify any deviations from the desired limits in Table 2.1-1. Transformer tap and switched shunt reactive compensation devices such as shunt capacitors and reactors were locked and continuous shunt devices were enabled when performing Category B load flow analysis. This methodology was used for both the pre-Project and post-Project scenarios.

Point-of-Delivery (POD) low voltage bus deviations were also assessed by first locking all tap changers and shunt reactive devices to identify any post-transient voltage deviations above 10%. Second, tap changers were then allowed to adjust, while shunt reactive devices remained locked to determine if any voltage deviations above 7% would occur in the Study Area. Third, all taps and shunt reactive device controls were allowed to adjust and voltage deviations above 5% were reported for both the pre-Project and post-Project systems.

7 The critical generator identified for this study is Keephills 3.


AltaLink

Page 19 June, 2016

3.2.1. Contingencies Studied

For the power flow analysis, all transmission facilities in the study area were monitored for voltage criteria violations and thermal violations under Category A conditions and under Category B contingency conditions. Power flow analysis was conducted for all Category B contingencies (69 kV facilities and above) within the study area, including the tie lines connecting the study area to the surrounding planning areas.

3.3. Voltage Stability (PV) Analysis

The objective of the voltage stability analysis is to determine the ability of the network to maintain voltage stability at all the buses in the Study Area under normal and abnormal system conditions. The Power-Voltage (PV) curve is a representation of voltage change as a result of increased power transfer between two systems. The reported incremental transfers will be to the collapse point. As per the AESO requirements, no assessment based upon other criteria such as minimum voltage will be made at the PV minimum transfer. Voltage stability analysis for post-Project scenarios will be performed. For load connection projects, the load level modelled in the post-connection scenarios are either the same or higher than in pre-Project scenarios. Therefore, voltage stability analysis for pre-Project scenarios will only be performed if post- Project scenarios show voltage stability criteria violations.

The voltage stability analysis was performed according to the Western Electricity Coordinating Council (WECC) Voltage Stability Assessment Methodology. WECC voltage stability criteria states, for load areas, post-transient voltage stability is required for the area modeled at a minimum of 105% of the reference load level for system normal conditions (Category A) and for single contingencies (Category B). For this standard, the reference load level is the maximum forecasted load for the Study Area.

Typically, voltage stability analysis is carried out assuming the worst case scenarios in terms of loading. Voltage stability analysis was performed by increasing the load in the Study Area and increasing the corresponding generation in the Wabamun (Area 40) and the Calgary (Area 6) planning areas.

3.3.1. Contingencies Studied

Voltage stability analysis was performed for the Category A condition and all Category B contingencies in the Study Area using the 2016-2017 WP post-Project scenario only.

5. Connection Alternatives

5.1. Overview

The Gainford 165S substation is owned by TMPL and no other customer is supplied from this POD substation. Thus, only alternatives involving development at the Gainford 165S substation were examined in this engineering study report.

5.2. Connection Alternatives Identified

The AESO examined two transmission alternatives to meet TMPL’s request for system access service:

Alternative 1: Upgrade the existing Gainford 165S substation by adding a second 138/4.16 kV transformer, with a rating of 15/20/25 MVA, and other associated equipment. Alternative 1 would require upgrading the existing 138 kV bus and the existing 4.16 kV bus, to facilitate the connection of the existing and new transformers. In addition, the substation fence would need to be expanded to accommodate the second transformer.

Alternative 2: Upgrade the existing Gainford 165S substation by replacing the existing 7.5/8.4 MVA, 138/4.16 kV transformer with a new 15/20/25 MVA, 138/4.16 kV transformer and adding other associated equipment. Alternative 2 would also require upgrading the existing 138 kV bus and the existing 4.16 kV bus, but fewer upgrades at both busses than necessary for Alternative 1, to facilitate the connection of the new transformer.

5.2.1. Connection Alternatives Selected for Further Studies

Alternative 2 was selected for further study.

5.2.2. Connection Alternatives Not Selected for Further Studies

Alternative 1 involves additional transmission facilities and hence, additional cost compared to Alternative 2. Similar to Alternative 2, Alternative 1 requires upgrades to the existing 138 kV bus and the existing 4.16 kV bus; however, the scope of bus upgrades required for Alternative 1 would be greater than for Alternative 2. Further, Alternative 1 requires expansion of the substation fence to accommodate the second transformer. Therefore, Alternative 1 was not selected for further study.

6. Technical Analysis of the Preferred Connection Alternative

6.1. Power Flow Analysis

The following is a summary of the power flow analysis results for Project.

6.1.1. Scenario 3: 2016-2017 Winter Peak

Similar to the 2016-2017 WP pre-Project scenario, no Reliability Criteria violations were observed under Category A conditions or under Category B contingency conditions.

Refer to Attachment B for power flow diagrams and a list of the top five Category B contingencies resulting in the highest post-contingency thermal loading on the facilities in the Study Area.

6.1.2. Scenario 4: 2017 Summer Peak

Similar to the 2017 SP pre-Project scenario, no Reliability Criteria violations were observed under Category A conditions or under Category B contingency conditions.

Refer to Attachment B for power flow diagrams and a list of the top five Category B contingencies resulting in the highest post-contingency thermal loading on the facilities in the Study Area.

6.2. Voltage Stability

Voltage stability analysis was performed using the 2016-2017 WP scenario (Scenario 3). The reference load level for the Study Area is 229 MW. The minimum incremental load transfer for the Category B contingencies is 5.0% of the reference load or 11.5 MW to meet the voltage stability criteria (0.05 x 229 MW = 11.5 MW). Table 6.2-1 summarizes the voltage stability results for Category A and the worst contingencies under Category B system conditions.

The voltage stability margin is met for all studied conditions.

The voltage stability diagrams are shown in Attachment C.

6.4. Conclusions

Based on the study results, Alternative 2 is technically viable. Power flow results indicate that there are no thermal criteria violations or voltage criteria violations prior to and after the Project. The voltage stability results confirm that the voltage stability margin of the study area meets the AESO requirement after the Project.

8. Summary and Conclusion

Project Overview

TMPL submitted a SASR to the AESO to supply electricity to a proposed industrial load addition in the Gainford area.

The SASR includes a request for a Rate DTS, Demand Transmission Service, contract capacity increase from 3.5 MW to 14.5 MW for the system access service provided at the existing Gainford 165S substation, and a request for transmission development. Specifically, TMPL requested an upgrade to the existing Gainford 165S substation to support the increased demand at the Gainford Pump Station for Kinder Morgan Canada’s proposed Trans Mountain Expansion Project.

The scheduled in-service date for the Project is February 1, 2019.

Recommendation

Based on the study results, Alternative 2 is technically viable. The studies show that the connection of the Project using Alternative 2 would not adversely impact the performance of the AIES. Therefore, it is recommended to proceed with the Project using Alternative 2 as the preferred option to respond to the TMPL’s request for system access service.
