Connection Engineering Study Report for AUC Application: EPCOR Riverview Substation New POD

Executive Summary

Project Overview

EPCOR Distribution & Transmission Inc. (EDTI), in its capacity as the legal owner of the electric

distribution system (DFO) in the City of Edmonton, submitted a request for system access

service to the Alberta Electric System Operator (AESO) to reliably serve growing demand for

electricity in southwest (SW) Edmonton. The DFO informed the AESO that this growing demand in SW Edmonton is currently served by its 25 kV distribution system.

The DFO’s request includes a Rate DTS, Demand Transmission Service, contract capacity of 24 MW, and a request for transmission development in SW Edmonton (collectively, the Project). Specifically, the DFO requested a new 240/25 kV point of delivery (POD) substation with two 240/25 kV transformers, four 240 kV breakers and associated equipment in SW Edmonton.

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

This report details the engineering studies undertaken to assess the impact of the Project on the

performance of the Alberta interconnected electric system (AIES).

Existing System

Geographically, the Project is located in the AESO planning area of Edmonton (Area 60), which

is part of the AESO Edmonton Planning Region. Edmonton (Area 60) is surrounded by the

AESO planning areas of Athabasca/Lac La Biche (Area 27), Fort Saskatchewan (Area 33),

Wetaskiwin (Area 31), and Wabamun (Area 40).

From a transmission system perspective, Edmonton (Area 60) consists of 500 kV, 240 kV,

138/144 kV, and 69/72 kV transmission systems. The existing 25 kV distribution system in SW

Edmonton is currently served by the Summerside and Poundmaker POD substations, which

are supplied through the 240 kV transmission system in Edmonton (Area 60).

Existing constraints in the Edmonton Planning Region are managed in accordance with the

procedures set out in Section 302.1 of the ISO rules, Real Time Transmission

Constraint Management.

Study Summary

Study Area

The Study Area for the Project consists of all 240 kV transmission facilities in Edmonton (Area

60) and the tie lines connecting Edmonton (Area 60) to the rest of the AIES. All transmission facilities rated at 240 kV and above within the Study Area were studied and monitored to assess the impact of the Project on the performance of the AIES, including any violations of the Reliability Criteria (as defined in Section 2.1.1).

Studies Performed

2018 winter peak (WP) and 2019 summer peak (SP) scenarios were studied.


Page 2

Power flow studies were performed for the 2018 WP and 2019 SP pre-Project and post-Project

study scenarios.

Voltage stability studies were performed for the 2018 WP post-Project study scenario.

Results of the Pre-Project Studies

Under the Category A and Category B conditions studied, no Reliability Criteria violations were

observed.

Connection Alternatives Examined for the Project

The DFO informed the AESO that it intends to request system access service to address

capacity and reliability concerns on its 25 kV distribution system in southeast (SE) Edmonton in

the near future. For the sake of ensuring transmission system planning efficiency, given the

proximity of the 25 kV distribution system in SW Edmonton to SE Edmonton, six transmission

alternatives were examined that address the current request for system access service (i.e.,

distribution system concerns in SW Edmonton), as well as the DFO’s capacity and reliability

concerns in SE Edmonton.

The AESO examined these six transmission alternatives in consultation with the DFO and the

legal owners of transmission facilities (TFOs) that own facilities in the area.

Alternative 1 – Upgrade the existing Petrolia substation and add a new POD substation in SE Edmonton

This alternative involves the following transmission development:

upgrading the existing Petrolia substation including adding two 240/25 kV

transformers, two 240 kV circuit breakers, and eight 25 kV feeder breakers and

associated equipment; and

adding a new POD substation in SE Edmonton, including adding two 240/25 kV

transformers, four 240 kV circuit breakers, and eight 25 kV feeder circuit breakers

and associated equipment; and connecting the new POD to the AIES.

Alternative 2 – Upgrade the existing Jasper substation and add a new POD substation in SE Edmonton


upgrading the existing Jasper substation including the addition of two 240/25 kV

transformers, two 240 kV circuit breakers, and eight 25 kV feeder circuit breakers

and associated equipment; and

adding a new POD substation in SE Edmonton including two 240/25 kV transformers,

four 240 kV circuit breakers, and eight 25 kV feeder circuit breakers and associated

equipment ;and connecting it to the AIES.

Alternative 3 – Upgrade the existing Summerside and Poundmaker substations and add a new POD substation in SE Edmonton



Page 3

upgrading the existing Summerside substation including adding one 240/25 kV

transformer, one 240 kV circuit breaker, and four 25 kV feeder circuit breakers and

associated equipment ;

upgrading the existing Poundmaker substation including adding one 240/25 kV



adding a new POD substation in SE Edmonton, including two 240/25 kV


and associated equipment ; and connecting it to the AIES.

Alternative 4 – Add a new POD substation in SW Edmonton, to be called the Riverview substation and upgrade the existing Summerside substation


adding a new POD substation in SW Edmonton, to be called the Riverview

substation, including two 240/25 kV transformers, four 240 kV circuit breakers, and

eight 25 kV feeder circuit breakers and associated equipment;

connecting the proposed Riverview substation to the existing 240 kV transmission

line 1043L (future 1139L) using an in-and-out configuration, between the approved

Harry Smith 367S substation and the Petrolia substation, by adding two new 240 kV

transmission circuits, each approximately 70 metres in length; and

upgrading the existing Summerside substation, including adding one 240/25 kV


associated equipment.

Alternative 5 – Add the proposed Riverview substation and add a new POD to SE Edmonton


adding the proposed Riverview substation, including two 240/25 kV transformers, four

240 kV circuit breakers, and eight 25 kV feeder circuit breakers and associated

equipment;







and associated equipment and connecting it to the AIES.

Alternative 6 – Upgrade the existing Summerside and Poundmaker substations


upgrading the existing Summerside substation, including replacing the two existing

240/25 kV transformers with two 240/25 kV transformers of higher capacity and adding a


Page 4

third 240/25 kV transformer, one 240 kV circuit breaker, and eighteen 25 kV feeder

circuit breakers and associated equipment; and

upgrading the existing Poundmaker substation, including adding one 240/25 kV



Alternatives Not Selected for Further Examination

Alternative 1 and Alternative 2 were not selected for further study because the TFO advised that

expanding the existing Petrolia and Jasper substations are not viable.

Alternative 3 and Alternative 6 were not selected for further study because the total costs are

estimated to be higher than the total costs of Alternative 4 and Alternative 5.1

Alternatives Selected for Further Examination

Alternative 4 and Alternative 5 were selected for further study. Both Alternative 4 and Alternative

5 involve adding the proposed Riverview substation to meet the request for system access

service.

Alternative 4 and Alternative 5 include different transmission facilities to address the capacity

and reliability concerns in SE Edmonton, which the DFO has indicated will be the subject of a

forthcoming request for system access service. Therefore, the selection of the preferred

transmission development to address the DFO’s capacity and reliability concerns in SE

Edmonton will be assessed as a part of a separate project, and is not within the scope of this

study.

For the purpose of responding to the DFO’s current request for system access service,

Alternative 4 and Alternative 5 are equivalent in scope. Therefore, only the addition of the

proposed Riverview substation, connected to the existing 240 kV transmission line 1043L

(future 1139L) in an in-and-out configuration, and including two 240/25 kV transformers, four

240 kV circuit breakers, and eight 25 kV feeder circuit breakers and associated equipment, will

be examined further.

Results of the Post-Project Studies

The post-Project studies were performed for the proposed Riverview substation with a Rate

DTS request of 24 MW.

Under the Category A and Category B conditions studied, no Reliability Criteria violations were observed. The voltage stability margin was met for all studied conditions.

Conclusions and Recommendations

1 Cost estimates for Alternative 3, Alternative 4, Alternative 5, and Alternative 6 are provided under a

separate cover.


Page 5

The connection assessment did not identify any pre-Project or post-Project system performance

issues. The connection assessment indicates that the Project will not adversely impact the

performance of the AIES.

Based on the connection assessment, adding the proposed Riverview substation to address the

request for system access service is technically acceptable.

Based on the connection assessment, adding the proposed Riverview substation and the

associated DTS is technically acceptable. The connection assessment did not identify any pre-

Project or post-Project system performance issues. The connection assessment indicates that

the Project will not adversely impact the performance of the AIES. No mitigation measures are

required as no Reliability Criteria violations were observed.

It is recommended to proceed with the Project by adding a new POD substation in SW

Edmonton as the preferred option to respond to the DFO’s request for system access service.

This includes: adding a new POD substation, to be designated the Riverview substation,

including two 240/25 kV LTC transformers, four 240 kV circuit breakers, and eight 25 kV feeder

circuit breakers and associated equipment; and adding two 240 kV circuits, approximately 70

metres in length, to connect the Riverview substation to the existing 240 kV transmission line

1043L (future 1139L) using an in-and-out configuration between the approved Harry Smith 367S

substation and the existing Petrolia substation.

A minimum rating equal or greater than the rating of the existing 240 kV transmission line 1043L

is recommended for the two new 70 metres 240 kV circuits.

The 240/25 kV LTC transformers at the Riverview substation are recommended to have a rating

of 75 MVA.

1.2.2.2. Existing Constraints

Existing constraints in the Edmonton Planning Region are managed in accordance with the

procedures set out in Section 302.1 of the ISO rules, Real Time Transmission Constraint

Management (TCM Rule).

1.2.2.3. AESO Long-Term Transmission Plans

The approved South and West Edmonton Area Transmission Development (SWEATD) will be in

the Study Area.2 The Harry Smith 367S substation, which was approved as a part of SWEATD,

is shown in Figure 1-1. The 240 kV transmission line between the Keephills 320P and the

Petrolia substations is currently designated the 1043L. As Figure 1-1 shows, once the approved

Harry Smith 367S substation is in service, the 240 kV transmission line between the Harry

Smith 367S and the Petrolia substations will be designated the 1139L. The Harry Smith 367S

substation is scheduled to be in-service December 5, 2017.

In addition to the approved SWEATD, the AESO 2015 Long-term Transmission Plan (2015

LTP)3 provides a plan for system developments in the City of Edmonton in the near-term,

medium-term, and long-term. According to the 2015 LTP, the following transmission system

enhancements were identified and were considered to be needed in the near-term (by 2020):

Convert Hardisty substation in east Edmonton to 240/15 kV from 72/15 kV

Add new 240 kV loop from Lambton substation in southeast Edmonton to Hardistysubstation and onto Bellamy substation at Rossdale

Discontinue use of 72 kV lines from Rossdale substation (Bellamy) to Strathconasubstation to Lambton substation

Replace existing 240/72 kV transformers at Clover Bar substation in northeastEdmonton with larger units

Add new 240/72 kV substation near Namao in northeast, cut into 240 kV line betweenCastle Downs substation and Victoria substation on north edge of downtown Edmonton

Add new 72 kV line from new substation to existing Namao substation

Add new 240/72 kV transformer at Castle Downs substation in northeast

Add new 72 kV transmission lines from Castle Downs substation to Kennedalesubstation, and onto Namao substation

Discontinue use of 72 kV lines between Clover Bar and Hardisty substations, andHardisty and Lambton substations

Discontinue use of existing 72 kV lines that connect Clover Bar, Victoria, Namao,Kennedale, and Woodcroft substations

Convert Victoria substation from 240/72/15 kV to 240/15 kV

Add new 240 kV line from Victoria substation to Bellamy substation

Discontinue use of 72 kV lines between Rossdale and Victoria substations

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 4 (collectively, the Reliability Criteria) 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.

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 include 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. 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 follows the

AESO Information Document ID# 2010-007RS, General Operating Practices - Voltage

Control (ID #2010-007RS). ID#2010-007RS relates to Section 304.4 of the ISO rules,

Maintaining Network Voltage. For the busses not listed in ID #2010-007RS, Table 2-1 in

the Transmission Planning Criteria – Basis and Assumptions applies.

For Category B conditions: The extreme voltage range values per Table 2-1 in the

Transmission Planning Criteria – Basis and Assumptions.

Desired post-contingency voltage change limits for three defined post event timeframes

as provided in Table 2-1.

2.1.2. ISO Rules and Information Documents

AESO ID# 2010-007RS was applied to establish pre-contingency voltage profiles in the Study Area. The TCM Rule was followed in setting up the study scenarios and assessing the study results. The Reliability Criteria is the basis for planning the AIES. In addition, due regard was given to the AESO’s Connection Study Requirements Document and the AESO’s Generation and Load Interconnection Standard.

2.2. Study Scenarios

At the time of study, the scheduled ISD for the Project was October 1, 2018. As a result, the studies were performed using 2018 winter peak (WP) and 2019 summer peak (SP) study scenarios. The scheduled ISD has since been revised from October 1, 2018 to October 1, 2019. The shift in the scheduled ISD does not materially impact the results of this connection assessment, and does not change the conclusions and recommendations contained in the report.

Table 2-2 provides a list of the study scenarios. The post-Project scenarios include the DFO-requested Rate DTS contract capacity of 24 MW. This connection assessment will assume a 0.9 lagging power factor for the load associated with the Project.

2.3. Load and Generation Assumptions

2.3.1. Load Assumptions

The Study Area load forecast used for this connection study is shown in Table 2-3 and corresponds to the forecasted area load during the forecasted Edmonton Region seasonal peak load, which was based on the AESO 2016 Long-term Outlook (2016 LTO). As part of its planning responsibilities, the AESO updates its corporate forecasts routinely to ensure they reflect the latest economic projects, factors and timing. While the AESO has updated its regional forecasts since the connection studies were performed, the use of the current AESO forecast, the AESO 2017 Long-term Outlook, would not materially alter the connection study results or affect the conclusions and recommendations in this report.

For the studies, when loads are modified to align with the load forecast in the 2016 LTO, the active power to reactive power ratio in the base case scenarios were maintained.

2.3.2. Generation Assumptions

The key generation dispatch conditions for the study scenarios are described in Table 2-4. The Cloverbar #3 generating unit was identified as the critical generating unit, and was considered to be out-of-service to represent the N-G condition for all studies.

2.3.3. Intertie Flow Assumptions and HVDC Assumptions

The Alberta-BC, Alberta-Montana, and Alberta-Saskatchewan intertie points are deemed to be too far away from the Study Area to have any material impact on the results of the studies. Therefore, the AESO planning base case intertie flow assumptions were used for the study scenarios.

The Western Alberta Transmission HVDC Line (WATL) and the Eastern Alberta Transmission HVDC Line (EATL) assumptions were expected to have minimal impact for the results of the studies. Therefore, the AESO planning base case HVDC assumptions were used for the study scenarios.

2.4. System Projects

The approved transmission developments that are a part of the SW Edmonton project are assumed to be in service for the studies. This includes the approved Harry Smith 367S substation and its connection to the existing 240 kV transmission line 1043L, which will be designated the 1139L (between the Harry Smith 367S and the Petrolia substations) after the Harry Smith 367S is connected.

The remaining of the AESO long term plans described in Section 1.2.2.3 were not included in the study scenarios.

2.5. Customer Connection Projects

Customer connection projects within the Study Area that have passed Gate 2 of the AESO

Connection Process as of October 2017 were modelled in the study scenarios based on their

positions in the AESO Connection Queue. Table 2-5 summarizes the customer connection

projects in Edmonton (Area 60) that were included in the studies.

2.7. Voltage Profile Assumptions

The AESO ID# 2010-007RS is used to establish the pre-contingency voltage profiles for key area busses prior to commencing any studies. Table 2-1 of the Transmission Planning Criteria – Basis and Assumptions applies for all the busses not included in the ID# 2010-007RS. These voltages will be utilized to set the voltage profile for the study base cases prior to power flow analysis. A list of operating voltages for the key busses in the Study Area is shown in Table 2-9.

3.2. Power Flow Analysis

Pre-Project and post-Project power flow studies were conducted to identify and compare study scenario thermal and voltage criteria violations as per the Reliability Criteria, and to identify any POD low voltage bus deviations that are outside the guidelines, shown in Table 2-1. The purpose of the power flow analysis is to quantify any violations in the Study Area, for both pre-Project and post-Project study scenarios. For the Category B power flow studies, the transformer taps and switched shunt reactive compensation devices such as shunt capacitors and reactors were locked and continuous shunt devices were enabled.

POD low voltage bus deviations were assessed by both the pre-Project and post-Project networks by first locking all tap changers and area capacitors to identify any post-transient voltage deviations above 10%. Second, tap changers were then allowed to adjust, while shunt reactive compensating devices capacitors remained locked; to determine if any voltage deviations above 7% would occur in the area. Third, all taps and shunt reactive compensating devices were adjusted and voltage deviations above 5% would be reported.

3.2.1. Contingencies Studied

The power flow studies included the Category A and all Category B contingencies (240 kV facilities only) within the Study Area.

3.3. Voltage Stability Studies

The objective of the voltage stability studies is to determine the ability of the transmission system to maintain voltage stability at all busses in the system under Category A and B


20

conditions. The power-voltage (PV) curve is a representation of voltage change as a result of increased power transfer between two systems. The incremental transfers are reported to the collapse point.

For load connection projects, the load level modelled in post-Project scenarios are the same or higher than in pre-connection scenarios. Therefore, voltage stability studies for pre-Project scenarios would only be performed if the 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 modelled at a minimum of 105% of the reference load level for Category A and Category B conditions. For this standard, the reference load level is the maximum established planned load.

Typically, voltage stability analysis is carried out assuming worst case loading scenarios. For the Project’s worst case scenario, load was increased in Edmonton (Area 60) and the corresponding generation was increased in Fort McMurray (Area 25).

3.3.1. Contingencies Studied

The voltage stability studies were performed for the Category A condition and all Category B contingencies (240 kV facilities only) in the Study Area for the 2018 WP post-Project scenario.

5. Connection Alternatives

5.1. Overview

The DFO informed the AESO that it intends to request system access service to address

capacity and reliability concerns on its 25 kV distribution system in southeast (SE) Edmonton in

the near future.5 For the sake of transmission system planning efficiency, given the proximity of

the 25 kV distribution system in SW Edmonton to SE Edmonton, six transmission alternatives

were examined that address the current request for system access service, as well as the

DFO’s SE Edmonton capacity and reliability concerns.

The AESO examined these six transmission alternatives in consultation with the DFO and the

legal owners of transmission facilities (TFOs) that own facilities in the area.

5.2. Transmission Alternatives Identified

Alternative 1: Upgrade the existing Petrolia substation and add a new POD substation in SE Edmonton

Alternative 1 involves the following transmission development:

upgrading the existing Petrolia substation including adding two 240/25 kV





and associated equipment and connection the new POD to the AIES

The DFO has advised that Alternative 1 would also require the addition of ten new 25 kV distribution circuits, with a total length of approximately 97 km.

Alternative 2: Upgrade the existing Jasper substation and add a new POD substation in SE Edmonton


upgrading the existing Jasper substation including adding two 240/25 kV





and associated equipment and connecting the new POD to the AIES.

The DFO has advised that Alternative 2 would also require the addition of ten new 25 kV

distribution circuits, with a total length of approximately 162 km.

5 See the EPCOR Distribution & Transmission Inc. Distribution Deficiency Report (DDR) for Riverview

Service Area, which is attached under a separate cover.


23

Alternative 3: Upgrade the existing Summerside and Poundmaker substations and a new POD substation in SE Edmonton


upgrading the existing Summerside substation including adding one 240/25 kV


associated equipment;

upgrading the existing Poundmaker substation including adding one 240/25 kV







Alternative 4: Add a new POD substation in SW Edmonton, to be called the Riverview substation, and upgrades to the existing Summerside substation

Alternative 4 involves the following transmission developments:

adding a new POD substation in SW Edmonton, to be called the Riverview

substation, including two 240/25 kV transformers, four 240 kV circuit breakers, and

eight 25 kV feeder circuit breakers and associated equipment;





upgrading the existing Summerside substation, including adding one 240/25 kV



The DFO has advised that Alternative 4 would also require the addition of ten new 25 kV

distribution circuits, with a total length of approximately 72 km.

Alternative 5: Add the proposed Riverview substation and add a new POD substation in SE Edmonton


adding the proposed Riverview substation, including two 240/25 kV transformers,

four 240 kV circuit breakers, and eight 25 kV feeder circuit breakers and associated

equipment;

transformers, four 240 kV circuit breakers and eight 25 kV feeder circuit breakers



Alternative 6: Upgrade the existing Summerside and the Poundmaker substations

Alternative 6 involves the following transmission developments:

upgrading the existing Summerside substation, including replacing the two existing

240/25 kV transformers with two 240/25 kV transformers of higher capacity and adding a

third 240/25 kV transformer, one 240 kV circuit breaker, and eighteen 25 kV feeder

circuit breakers and associated equipment; and

upgrading the existing Poundmaker substation, including adding one 240/25 kV




5.2.1. Transmission Alternatives Not Selected for Further Examination

Alternative 1 and Alternative 2 were not selected for further study because the TFO advised that

expansion of the Petrolia and Jasper substations is not viable, as explained further below.

The TFO has advised that Alternative 1 is not acceptable from an environmental and a

stakeholder impact perspective. From an environmental perspective, the TFO advised that there

was a spill on the Petrolia substation site in the early 1980s, which the TFO may not be able to

manage if transmission facilities are added to the substation. The TFO has also advised that

expanding the Petrolia substation would have an adverse impact to local residents, specifically

because the expanded substation site would encroach on an existing community park and

baseball diamond. As a result, Alternative 1 was not selected for further study.

Alternative 2 was not selected for further studies because the TFO has advised that there is

insufficient space within and around the Jasper substation to accommodate the addition of the

required transmission facilities. As a result, Alternative 2 was not selected for further study.

Alternative 3 and Alternative 6 were not selected for further study because the total combined

costs of the distribution and transmission developments were estimated to be higher than the

total combined costs of the distribution and transmission developments associated with

Alternative 4 and Alternative 5.6

6 Cost estimates for Alternative 3, Alternative 4, Alternative 5, and Alternative 6 are provided under a

separate cover.


25

5.2.2. Transmission Alternatives Selected for Further Examination

Alternative 4 and Alternative 5 were both considered technically feasible and were selected for

further study. Both Alternative 4 and Alternative 5 involve adding the proposed Riverview

substation to address the DFO’s request for system access service.

Alternative 4 and Alternative 5 include different transmission facilities7 to address the capacity

and reliability concerns in SE Edmonton, which the DFO has indicated will be the subject of a

forthcoming request for system access service. Therefore, the selection of the preferred

transmission development to address the DFO’s capacity and reliability concerns in SE

Edmonton will be assessed as a part of a separate project, and is not within the scope of this

study.

For the purpose of responding to the DFO’s current request for system access service,

Alternative 4 and Alternative 5 are equivalent in scope; both alternatives address the current

request for system access service by adding a proposed Riverview substation in SW Edmonton

and connecting it to the existing 240 kV transmission line 1043L (future 1139L) in an in-and-out

configuration. Therefore, only this scope will be examined further in this report.

7 Alternative 4 includes adding a new POD substation in SE Edmonton and Alternative 5 includes

upgrading the existing Summerside substation.

8. Conclusions and Recommendations

The connection assessment did not identify any pre-Project or post-Project system performance

issues. The connection assessment indicates that the Project will not adversely impact the

performance of the AIES. No mitigation measures are required as no Reliability Criteria

violations were observed.

It is recommended to proceed with the Project by adding a new POD substation in SW

Edmonton as the preferred option to respond to the DFO’s request for system access service.

This includes: adding a new substation, to be designated the Riverview substation, including

two 240/25 kV LTC transformers, four 240 kV circuit breakers, and eight 25 kV feeder circuit

breakers and associated equipment; and adding two 240 kV circuits, each approximately 70

metres in length, to connect the Riverview substation to the existing 240 kV transmission line

1043L (future 1139L) using an in-and-out configuration between the approved Harry Smith 367S

substation and the existing Petrolia substation.

A minimum rating equal or greater than the rating of the existing 240 kV transmission line 1043L

is recommended for the two new 240 kV circuits.

Transformer Sizing Recommendation

EDTI DFO has advised that it foresees a need for 6 feeders in SW Edmonton in the near term

(within 10 years). EDTI DFO has also advised that provisions need to be made to eventually

enable the connection of 8 feeders in the medium term at the Riverview substation. EDTI TFO

has also advised that because it plans to install a 25 kV switchgear that will be gas-

insulated (GIS), it is not practical to install 6 feeder breakers now and 2 additional feeder

breakers in the future.

Since EDTI’s transformers have an average life of 50 years, EDTI DFO has requested that,

should the Riverview substation be chosen as the preferred alternative to address the Project

need, provisions be made to enable the connection of 8 feeders in the medium term at the

Riverview substation. EDTI DFO foresees that these feeders will eventually be loaded to their

design load rating of 12 MVA each.

EDTI TFO has advised that it sizes transformers based on their ability to serve all substation

load under an N-1 contingency of a transformer. For the proposed Riverview substation, that

would mean that two transformers would be needed. Each transformer should be capable of
