This memo documents customer stakeholder feedback concerning BC Hydro’s 1
October 7, 2014 Workshop No. 4 (the second COS methodology workshop) and 2
BC Hydro’s consideration of this input. Workshop No. 4 was held in Vancouver, B.C. 3
with customers also being provided an opportunity to listen into the discussions 4
remotely through a webinar. A Copy of the Workshop No. 4 presentation slides can 5
be found on the BC Hydro regulatory website at 6
http://www.bchydro.com/about/planning_regulatory/2015-rate-design.html. Customer 7
input was received during the workshop as well as through feedback forms and 8
written comments submitted during a subsequent 30-day comment period, which 9
began with the posting of draft Workshop No. 4 notes on October 17, 2014. 10
The memo is structured as follows: 11
The main body, consisting of: 12
Part 1, which summarizes those COS methodology items which BC Hydro 13
believes are the subject of a fair degree of consensus 14
Part 2, which addresses the five COS methodology items on which BC Hydro 15
believes the parties have not reached a fair degree of consensus: Heritage 16
hydro classification; Heritage thermal classification; Smart Meter Infrastructure 17
(SMI) regulatory account cost classification and allocation; aspects of 18
Distribution classification and allocation; and Customer Care cost allocation. 19
Part 2 provides a summary of comments, grouped with respect to these five 20
items, along with BC Hydro’s consideration of input. 21
Attachment 1 includes the Workshop No. 4 notes which provide a more detailed 22
description of issues (including questions and answers). 23
Attachment 2 contains the feedback forms received during the written comment 24
period. 25

Attachment 3 presents an Independent Power Producer (IPP) cost of energy 1
functionalization issue that has arisen as a result of BC Hydro responding to a 2
comment raised by British Columbia Utilities Commission (Commission, BCUC) 3
staff concerning the treatment of IPP costs deemed to be capital related under 4
International Financial Reporting Standards (IFRS). For F2016, these IPP-related 5
amounts (amortization, tax and finance charges) have been functionalized as 6
Generation. The F2016 impact of this adjustment on Revenue to Cost ratios (R/C) 7
ratios compared to perpetuating the prior treatment is detailed in Attachment 3. 8
Attachment 4 provides BC Hydro’s response to marginal COS issues raised by 9
Canadian Office and Professional Employees Union Local 378 (COPE 378) in its 10
written comments provided on November 11, 2014. 11
1 COS Methodology Items With Fair Degree of 12
Consensus 13
Based on input concerning the two COS methodology workshops (Workshop No. 2 14
and Workshop No. 4), BC Hydro believes that there is a fair degree of consensus on 15
the following COS methodology items: 16
COS Methodology Item BC Hydro Observation
Embedded COS Approach With the exception of COPE 378, all stakeholders commenting on COS issues
supported BC Hydro continuing with the embedded COS approach. COPE 378
advocates for a marginal COS approach. BC Hydro rejects a marginal COS
approach for the reasons set out in Part 1 of BC Hydro’s consideration memo
concerning Workshop No. 2 (Workshop 2 Consideration Memo) and in
Attachment 4 to this consideration memo.

COS Methodology Item BC Hydro Observation
Demand Side Management (DSM) Functionalization
With the exception of British Columbia Old Age Pensioners Organization
(BCOAPO), stakeholders providing Workshop No. 4-related written comments
agreed with BC Hydro’s proposal to modify Commission 2007 Rate Design
Application (RDA) Direction 6 from functionalizing DSM-related costs as
90 per cent Generation and 10 per cent Transmission to functionalizing
DSM-related costs as 90 per cent Generation, 5 per cent Transmission and
5 per cent Distribution.
While BCOAPO agreed that functionalizing DSM costs between Generation,
Transmission and Distribution using benefits accruing makes sense, it asked for
more explanation regarding BC Hydro’s proposed functionalization. BC Hydro
provides this in section 1.1.
IPP Contracts Classification Most stakeholders providing Workshop No. 4-related written comments agreed
with BC Hydro’s preferred Option 2 (value of capacity) to classify IPP costs.
It is not clear to BC Hydro whether Commercial Energy Consumers Association
of British Columbia (CEC) opposes Option 2, and if so, what CEC is proposing
as an alternative. CEC states that it expects that the Alcan, Island Generation
and biomass IPP contracts, which in contrast to most IPP contracts are not for
intermittent resources and provide dependable capacity, “may be treated
differently”. As described in section 5.3 and Attachment 4 of the Workshop No. 2
Consideration Memo, BC Hydro took into account the nature of the Alcan, Island
Generation and biomass contracts in arriving at its preference for Option 2.
BC Hydro rejected Option 3 (contract structure) as an IPP classification method
because it does not yield reasonable results.
CEC also states that it expects “to link the IPP issue to BC Hydro capacity at its
Mica and Revelstoke plants for a balance of equitable treatment”. BC Hydro
does not understand this comment. BC Hydro remains of the view that IPPs
should be classified separately from BC Hydro Heritage hydroelectric assets
such as Mica and Revelstoke Generating Stations because most IPP contracts
provide a different product as they are for intermittent resources. This is the
![Page 7: 2015 01 22 Workshop 4 COS Methodology BC Hydro Summary … · 2015-01-23 · October 7, 2014 Workshop No. 4 Cost of Service (COS) Methodology – BC Hydro Summary and Consideration](https://reader033.vdocuments.us/reader033/viewer/2022042404/5f186adf91d8c16412354d33/html5/thumbnails/7.jpg)

reason BC Hydro rejected Option 5 (applying the load factor approach to IPPs).
BCOAPO notes that Option 2 mixes marginal and embedded costs. BCOAPO
observes that while the choice of using embedded or marginal values for IPP
classification purposes does not materially impact the energy/demand split,
BCOAPO is concerned that this could change if substantially more IPPs are
added to the system. BC Hydro addresses this concern in section 1.2 of this
memo.
Transmission Classification With the exception of COPE 378, all stakeholders providing Workshop No. 2
and/or Workshop No. 4-related written comments on this topic thought
reasonable BC Hydro’s proposal to continue with the 2007 RDA decision
approach that Transmission should be classified as 100 per cent demand-related
because serving peak loads remains the primary planning consideration for
capital expenditures on the transmission system.
With the exception of CEC, those stakeholders that provided
Workshop No. 4-related written comments agreed that radial lines should be
treated the same as the overall transmission system. CEC maintains that radial
lines that bring generation to loads may be candidates for different treatment. In
response to CEC’s comment, BC Hydro notes that the Revenue Requirement
Application (RRA) includes an adjustment that functionalizes Generation Related
Transmission Assets (GRTA) from Transmission into Generation. With the
exception of GRTA functionalized to Generation in the RRA, BC Hydro agrees
with the reasoning of BCOAPO (treat radial lines similar to overall Transmission
given their small value).

Customer Care Classification
With the exception of COPE 378, all stakeholders providing Workshop No. 2
and/or Workshop No. 4-related written comments on this topic agreed with
BC Hydro’s proposal to classify Customer Care costs 100 per cent as
customer-related rather than the current 65 per cent demand/35 per cent
customer classification mandated by Commission 2007 RDA Direction 4.
Customer Care costs do not vary with demand, and a 100 per cent customer
classification is consistent with how other utilities treat Customer Care costs.
Allocation of BC Hydro Generation and IPP Demand-related Costs and Transmission Costs
Parties providing Workshop No. 4-related written comments on this topic agreed
with BC Hydro’s proposal to continue with 2007 RDA Direction 3, which
mandates a 4 Coincident Peak (CP) allocation of Generation demand-related
and Transmission costs on the basis that winter peak occurred in each of the
months from November through January in recent years and that the February
peak is often close to the annual peak.
While BC Hydro provided sensitivities at Workshop No. 4 (3CP, variations on
4CP), the results indicate little change from the current 4CP approach. BC Hydro
agrees with BC Sustainable Energy Association and Sierra Club British
Columbia’s (BCSEA) point that simplicity favours the status quo.
1.1 BCOAPO Request Regarding Further Proposed DSM 1
Functionalization Explanation 2
BC Hydro’s rationale for its proposal starts with 2007 RDA Direction 6 functionalizing 3
DSM-related costs as 90 per cent Generation and 10 per cent Transmission. The 4
Commission in the 2007 RDA decision cited the BC Hydro, BCOAPO, CEC and 5
Association of Major Power Consumers of British Columbia (then called Joint 6
Industry Electricity Steering Committee) final arguments which agreed that DSM 7
costs should be functionalized 90 per cent Generation and 10 per cent 8
![Page 9: 2015 01 22 Workshop 4 COS Methodology BC Hydro Summary … · 2015-01-23 · October 7, 2014 Workshop No. 4 Cost of Service (COS) Methodology – BC Hydro Summary and Consideration](https://reader033.vdocuments.us/reader033/viewer/2022042404/5f186adf91d8c16412354d33/html5/thumbnails/9.jpg)

Transmission, and found that DSM-capital related and operating costs are incurred 1
to serve load and that these savings occur primarily in Generation.1 2
BC Hydro sees no compelling reason to propose discontinuance of that part of 3
2007 RDA Direction 6 functionalizing DSM-related costs as 90 per cent Generation. 4
BC Hydro DSM initiatives are primarily energy-focused and are primarily undertaken 5
to defer Generation resources. The DSM target, set in the 2013 Integrated Resource 6
Plan (IRP), anticipates 7,800 gigawatt hours per year (GWh/year) of energy savings 7
and 1,400 megawatts (MW) of associated capacity savings. These targeted energy 8
and capacity savings are included in BC Hydro’s load-resource balances with the 9
result that BC Hydro avoids entering into new or renewing existing contracts for 10
energy resources, and undertaking capacity-based Resource Smart additions to 11
existing BC Hydro generating stations and/or entering into new contracts for capacity 12
generation resources. In the 2013 IRP, BC Hydro states that prior to pursuing the 13
DSM target it would require energy and capacity generation resources in F2016; 14
after implementation of the DSM target BC Hydro anticipates requiring energy 15
generation resources in F2022 and capacity generation resources in F2018.2 16
BC Hydro also notes that most surveyed jurisdictions functionalize DSM as primarily 17
Generation (including functionalizing DSM as 100 per cent Generation). 18
BC Hydro is of the view that DSM initiatives have some Transmission and 19
Distribution deferral benefits and observes the following: 20
1. Generation, Transmission, and Distribution deferral benefits are included in 21
DSM cost-effectiveness tests such as the Total Resource Cost test. 22
1 In the Matter of British Columbia Hydro and Power Authority: 2007 Rate Design Application, Phase-1,
Decision, October 26, 2007 (2007 RDA Decision), page 93. BCOAPO noted in its 2007 RDA final argument that BC Hydro had, in its 1998 COS study, functionalized DSM as 90 per cent generation; refer to page 11 of BCOAPO’s August 17, 2007 final argument.
2 This is based on the no liquefied natural gas (LNG) scenario. Refer to Appendix 9A, Tables 1 and 2 of the 2013 IRP; copy available at https://www.bchydro.com/energy-in-bc/meeting_demand_growth/irp/document_centre/reports/november-2013-irp.html.

2. Several years ago, BC Hydro undertook preliminary high-level analysis on 1
Transmission and Distribution DSM benefits and concluded the benefits are 2
primarily found at a regional transmission and substation level (around $10 per 3
kilowatt year (/kW-year)). These benefits are described in the DSM Expenditure 4
Plan, which was filed as Appendix II3 in BC Hydro’s F2012 to F2014 Revenue 5
Requirements Application (F12-F14 RRA). Qualitatively, BC Hydro believes 6
there are some Transmission and Distribution benefits from DSM but 7
acknowledges that it has more confidence in Generation capacity deferral 8
benefits (around $55/kW-year based on Revelstoke Unit 6). 9
3. Updating the previous assessment of Transmission and Distribution benefits 10
would be laborious and likely have no accuracy gain because of the number of 11
assumptions required (i.e., savings from DSM initiatives would need to be 12
disaggregated to individual substations or lines and an assessment of deferral 13
potential would need to be made for each asset). Since there are more than 14
100 regional transmission lines, 200 distribution substations and 15
1500 distribution feeders this would be a significant undertaking yielding 16
uncertain benefits. 17
Given the above observations, BC Hydro continues to believe a portion of DSM 18
should be functionalized as Transmission- and Distribution- related but notes that 19
allocation of the final 10 per cent wholly to Generation, wholly to Transmission, or as 20
between Transmission and Distribution, will not materially impact the allocation of 21
cost to rate classes; refer to section 2 of the Workshop No. 4 Discussion Guide. 22

1.2 BCOAPO and IPP Classification Option 2 1
BCOAPO is correct that BC Hydro’s preferred Option 2 for classifying IPP costs is 2
based on the 2013 IRP’s Long-Run Marginal Cost (LRMC) for energy (upper end of 3
$100 per megawatt hour (/MWh)) and for Generation-related capacity ($55/kW-year) 4
in $2013. BC Hydro considered using embedded costs for valuing IPP energy and 5
capacity contributions, but determined it is not possible to estimate the embedded 6
cost of IPP capacity as both capacity and energy are combined within a single IPP 7
price. As set out in BC Hydro’s response to COS consultants’ recommendation #4 in 8
the Workshop No. 1 Discussion Guide, BC Hydro considered an additional 9
sensitivity that was based on the 2009/2010 Clean Power Call (CPC) - $34/kW-year 10
(based on Mica Unit 5) and $124/MWh ($2009) for capacity and energy respectively. 11
BCOAPO notes that the choice of using the 2013 IRP values or the CPC/Mica Unit 5 12
based values does not materially impact the energy/demand split. However, 13
BCOAPO is concerned that this could change if substantially more IPPs are added 14
to the system. BC Hydro does not foresee adding substantially more green-field 15
IPPs to the system over the next ten years. The 2013 IRP recommends reliance on 16
the DSM target, renewal of existing IPP contracts and external markets as a 17
capacity-based bridging mechanism to meet the forecasted need for energy and 18
capacity until Site C’s earliest in-service date in F2024.4 DSM and renewals of 19
existing IPP contracts have unit energy costs significantly below green-field IPPs,5 20
and result in the energy LRMC range for the next ten years of between $85/MWh to 21
$100/MWh set out in the 2013 IRP. 22
4 Supra, note 2, Chapter 9, Recommended Actions Nos 1, 4 and 7. 5 For example, BC Hydro’s first IPP contract renewal after approval of the 2013 IRP was for $43.89/MWh
($2013) on a levelized basis for 166 GWh/year of firm energy for a term of just over 11 years; refer to Commission Order No. E-19-14, Appendix A, page 8 of 18 concerning Covanta Burnaby Renewable Energy, ULC’s SEEGEN municipal solid waste incineration plant.

2 Five COS Methodology Items Which Do Not Have a 1
Fair Degree of Consensus 2
2.1 BC Hydro Hydroelectric Generation Classification 3
2.1.1 Participant Comments 4
Stakeholders had different views on Heritage hydroelectric generation classification: 5
Progress Energy Canada Ltd. (PECL) and Canadian Association of Petroleum 6
Producers (CAPP) supported a capacity factor based approach weighted by 7
book value (Option 3). PECL suggested that a load factor approach (Option 1) 8
would disincent customers from maintaining a high load factor while CAPP 9
stated the method would disincent participation in Time of Use (ToU) rates. 10
Both PECL and CAPP suggested that a load factor method would 11
inappropriately classify too much of the cost from new capacity units (i.e., Mica 12
Units 5 and 6, and Revelstoke Unit 5) as energy rather than demand-related. 13
BCSEA supported the load factor based approach proposed by BC Hydro 14
(Option 1B). BCOAPO stated that a load factor approach makes sense, but 15
raised concern with Option 1B to the extent there is a mismatch between 16
customer load and IPP generation that may include reserves. 17
CEC appears to favour a capacity factor approach, although it states that a load 18
factor approach will continue to be of interest along with different capacity factor 19
approaches that either include or exclude plant book values. 20
2.1.2 BC Hydro Consideration 21
The classification of BC Hydro’s Heritage hydroelectric facilities is an important 22
methodology within the COS study as the associated costs (capital costs and share 23
of operation and maintenance (O&M), and taxes) exceed $1 billion or 25 per cent of 24
BC Hydro’s F2016 revenue requirement. 25
![Page 13: 2015 01 22 Workshop 4 COS Methodology BC Hydro Summary … · 2015-01-23 · October 7, 2014 Workshop No. 4 Cost of Service (COS) Methodology – BC Hydro Summary and Consideration](https://reader033.vdocuments.us/reader033/viewer/2022042404/5f186adf91d8c16412354d33/html5/thumbnails/13.jpg)

Page 10
While BC Hydro continues to believe that Option 1B remains the best choice for 1
reasons discussed in the Workshop No. 4 Discussion Guide, BC Hydro also believes 2
that both the load factor and capacity factor approach have merit. For example, 3
CAPP and PECL are correct in noting that Mica Units 5 and 6, Resource Smart 4
upgrades to BC Hydro’s Mica Generating Station with F2016-related costs, result in 5
significant dependable capacity additions to BC Hydro’s system (approximately 6
500 MW each) with virtually no energy gains. BC Hydro’s next two largest Resource 7
Smart upgrade opportunities – Revelstoke Unit 6 and G.M. Shrum Units 1 to 5 8
Capacity Increase - would also result in significant dependable capacity additions to 9
BC Hydro’s system (488 MW and 220 MW, respectively) with virtually no energy 10
gains.6 In addition, a capacity factor approach is used in other jurisdictions, although 11
these jurisdictions are thermal as opposed to hydroelectric based. 12
As a result, BC Hydro will: 13
Use Option 1B (55 per cent energy/45 per cent demand) in its F2016 COS 14
study; but 15
Will bring forward two sensitivities: Option 3 (45 per cent energy/55 per cent 16
demand); and a 50 per cent energy/50 per cent demand split based on 17
BC Hydro’s historic classification of Heritage hydroelectric facilities. A 18
50 per cent energy/50 per cent demand split is a compromise approach that 19
recognizes the limitations of both the load factor and capacity factor 20
approaches and roughly represents an average of the Option 1B and Option 3 21
results. 22
In its 2015 RDA, BC Hydro will state that it does not oppose adoption of any of the 23
Option 1B, Option 3 and 50 per cent energy/50 per cent demand approaches. 24
In response to PECL, BC Hydro believes that a load factor approach is a reasonable 25

serves system load. Although Option 1B increases the proportion of cost classified 1
as energy relative to 2007 RDA Direction 5 (45 per cent energy/55 per cent 2
demand), BC Hydro disagrees that this would provide a significant disincentive for 3
high load factor customers to maintain their high load factors. Customer usage 4
decisions are largely based on non COS factors such as rate design and overall 5
energy costs relative to alternatives available. 6
CAPP indicated there may be conflicts between the system load factor approach 7
and ToU rates. BC Hydro does not believe there is a conflict because: 1) no 8
industrial customers have chosen BC Hydro’s existing voluntary industrial ToU rate 9
(Rate Schedule (RS) 1825), and to date industrial customer feedback has been that 10
BC Hydro should pursue a load curtailment program as opposed to a revamped 11
RS 1825; 2) industrial customers already have a relatively flat load profile so any 12
savings associated with a reduction in industrial 4CP demand from a ToU rate is 13
likely to be marginal relative to potential savings from other customer classes with 14
lower load factors; and 3) B.C. Government policy prohibits BC Hydro from pursuing 15
mandatory ToU rates for its residential and commercial customers. The impact of 16
voluntary ToU rates for residential and commercial customers on the system load 17
factor is highly questionable. Stakeholders agreed with BC Hydro that a voluntary 18
ToU rate for residential customers should not be pursued (refer to BC Hydro’s 19
consideration memo concerning Workshop No. 3 and the reasons BC Hydro 20
provides for not pursuing a voluntary ToU rate for its residential customers). 21
BC Hydro does not favour adopting a voluntary ToU rate for commercial customers 22
for similar reasons but will explore this option at its upcoming Large General Service 23
(LGS)/Medium General Service (MGS)/Small General Service (SGS) workshop on 24
January 21, 2015. 25
BC Hydro acknowledges CAPP’s concern with respect to potential LNG plants 26
influencing the system load factor but notes that no LNG loads are included in the 27
F2016 load forecast used to develop the COS study. According to the 2013 IRP, 28
![Page 15: 2015 01 22 Workshop 4 COS Methodology BC Hydro Summary … · 2015-01-23 · October 7, 2014 Workshop No. 4 Cost of Service (COS) Methodology – BC Hydro Summary and Consideration](https://reader033.vdocuments.us/reader033/viewer/2022042404/5f186adf91d8c16412354d33/html5/thumbnails/15.jpg)

Page 12
LNG load is not expected before F2020. In BC Hydro’s view the impact of LNG is an 1
issue that should be considered in future COS work. 2
With respect to BCOAPO’s comments regarding Option 1B, BC Hydro notes that 3
IPP supply is almost entirely used to meet domestic “customer load”. During 4
operations, BC Hydro relies upon Heritage resources to provide operating reserves 5
because IPP supply is mostly intermittent with availability determined by 6
environmental conditions such as river flow and wind speeds. A few IPP projects 7
such as Island Generation are dispatchable but they are not set up for sufficiently 8
fast acting dispatch that meets operating reserve requirements. 9
It is not clear what additional information CEC requires to form an opinion of the 10
various options and methodologies suggested by BC Hydro. CEC appears not to 11
favour the load factor approach; instead some form of capacity factor approach 12
appears to be supported. CEC states that it “will look for capacity factor approaches 13
which are not based on plant book values”. In Workshop No. 2, BC Hydro explored a 14
capacity factor approach which is not weighted by book value and uses an average 15
capacity factor for the entire Heritage hydroelectric system (Option 2) in addition to a 16
capacity factor approach that is weighted by book value (Option 3); refer to section 4 17
of the Workshop No. 2 Discussion Guide. As stated in the Workshop No. 2 18
Consideration Memo, BC Hydro is of the view that Option 3 is preferable to Option 2 19
because the value of each generating facility is an important driver of cost as 20
facilities with higher book values will incur higher capital-related costs such as 21
financing charges, depreciation and return on equity relative to facilities with lower 22
book value. In any event, BC Hydro is of the view that the two COS study Heritage 23
hydroelectric generation classification sensitivities (Option 3 and a 50 per cent 24
energy/50 per cent demand split) provide a reasonable range in relation to 25
BC Hydro’s preferred Option 1B. 26

2.2 BC Hydro Thermal Generation Classification 1
2.2.1 Participant Comments 2
PECL stated there should be consistency between hydroelectric and thermal 3
classification methods. CAPP suggested a capacity factor approach and noted this 4
is consistent with its views on Heritage hydroelectric classification. BCOAPO and 5
BCSEA supported BC Hydro’s proposed treatment for the three Heritage thermal 6
facilities, while CEC did not take a position and expressed interest in exploring how 7
trade considerations may impact the choice of a classification method. 8
2.2.2 BC Hydro Consideration 9
BC Hydro agrees that consistency between Heritage hydroelectric and thermal 10
classification methods is desirable where possible. However, BC Hydro has 11
concerns with applying capacity factor approaches to the three Heritage thermal 12
plants and these are discussed between pages 8 and 10 of the Workshop No. 4 13
Discussion Guide. In the case of Fort Nelson Generating Station (FNG), these 14
concerns include the fact that there is a relationship between trade and the capacity 15
factor calculation, which addresses CEC’s comment. Using a capacity factor 16
approach, surplus FNG generating capacity would effectively be classified as 17
100 per cent demand even though it may be used for trade purposes throughout the 18
year. There will be no relationship between Burrard Thermal Generating Station 19
(Burrard) and trade given that Burrard’s generating capability will be retired. 20
In any event, BC Hydro notes that the classification method selected for three 21
Heritage thermal plants does not change COS R/C ratios when reported to 22
one decimal place. 23

2.3 SMI Classification and Allocation 1
2.3.1 Participant Comments 2
Stakeholders continue to have diverse opinions on the treatment of SMI-related 3
regulatory account costs. PECL and CEC agreed with BC Hydro’s proposed 4
classification of SMI-related costs as 100 per cent customer. COPE 378 advanced 5
that SMI was justified by system benefits such as outage detection and theft 6
reduction rather than improvements or savings in metering or customers’ 7
consumption. BCOAPO noted that a 100 per cent customer classification (Option 1) 8
is consistent with industry practice but felt that a 70 per cent customer/30 per cent 9
energy classification (Option 3) reflects the rationale for implementing SMI and cost 10
causality. BCOAPO also suggested a weighted metering allocator be used given 11
that the difference in costs between the legacy meters is not likely the same as the 12
difference in costs for the smart meters. BCSEA requested clarification on the 13
distinction between SMI-related costs, SMI regulatory account amortization and SMI 14
capital costs. 15
2.3.2 BC Hydro Consideration 16
Clarification of terminology 17
In response to BCSEA’s request for clarification of SMI-related cost terminology, 18
BC Hydro provides the following. 19
“SMI-related costs” include both: 20
The operating costs deferred to the SMI regulatory account (as established in 21
Commission Order No. G-64-09 and continued by Order Nos. G-115-11, 22
G-77-12A, and G-166-13) 23
“SMI capital costs”, which are the non-deferred costs associated with financing, 24
depreciation and return on equity charges for SMI capitalized assets (i.e., 25
![Page 18: 2015 01 22 Workshop 4 COS Methodology BC Hydro Summary … · 2015-01-23 · October 7, 2014 Workshop No. 4 Cost of Service (COS) Methodology – BC Hydro Summary and Consideration](https://reader033.vdocuments.us/reader033/viewer/2022042404/5f186adf91d8c16412354d33/html5/thumbnails/18.jpg)

meters, communication equipment and associated software) that are included 1
in BC Hydro’s rate base. 2
“SMI regulatory account amortization” refers to the portion of the SMI regulatory 3
account balance that is included in the current revenue requirement. The portion of 4
costs related to SMI-related regulatory account recoveries is $31.3 million in F2016. 5
This amount is the subject of the classification discussion that follows. 6
Classification: Preferred Option and COS Study Sensitivity 7
BC Hydro continues to believe that a 100 per cent customer classification is 8
appropriate for SMI-related regulatory account costs for the reasons set out in the 9
Workshop No. 4 Discussion Guide. 10
BC Hydro undertook additional jurisdictional analysis as part of developing this 11
consideration memo with respect to SMI classification and allocation. BC Hydro 12
contacted Georgia Power Company to better understand its rationale for classifying 13
SMI costs as 100 per cent customer. Georgia Power Company stated that it did so 14
because SMI meters are like any meter in that costs do not vary based on 15
kilowatt (kW) or kilowatt hour (kWh) usage of a customer; rather, it is driven by the 16
fact that each customer requires a meter. BC Hydro finds this reasoning persuasive. 17
Although BC Hydro expects there to be loss reduction-related energy savings from 18
SMI in F2016, these savings are estimates at the present time (line losses cannot be 19
measured directly until BC Hydro has fully deployed system metering, anticipated to 20
be December 2015). BC Hydro believes it would be prudent to wait three years 21
before considering whether energy-related benefits from SMI should be incorporated 22
in the COS classification methodology. 23
![Page 19: 2015 01 22 Workshop 4 COS Methodology BC Hydro Summary … · 2015-01-23 · October 7, 2014 Workshop No. 4 Cost of Service (COS) Methodology – BC Hydro Summary and Consideration](https://reader033.vdocuments.us/reader033/viewer/2022042404/5f186adf91d8c16412354d33/html5/thumbnails/19.jpg)

2015 Rate Design Application
Page 16
In response to BCOAPO and COPE 378’s comments, BC Hydro provides the 1
following options analysis: 2
Under the status quo, the annual recovery of deferred SMI costs would be 3
treated the same as any Distribution O&M cost. These costs would be classified 4
as around 79 per cent demand-related and 21 per cent customer-related under 5
the proposed COS methodology for classifying Distribution costs in F2016. 6
BC Hydro does not believe it is reasonable to classify such a high portion of 7
SMI costs as demand-related. 8
Option 1 (preferred): The classification of meter-related costs as 100 per cent 9
customer-related is simple and defendable from a historical cost allocation 10
perspective, and has overwhelming jurisdictional support. 11
Option 2 was rejected by BC Hydro because 100 per cent classification to 12
energy is unreasonable. This was discussed during Workshop No. 4. 13
Option 3 (Workshop No. 4): The 70 per cent customer/30 per cent energy split 14
previously proposed is based on F2016 data and so it would likely change 15
considerably year over year. This method would assign an additional 16
$2.5 million in costs to Transmission service customers, which in BC Hydro’s 17
view is not reasonable. However, given BCOAPO’s and COPE 378’s 18
comments, BC Hydro developed two additional options (Options 4 and 5). 19
Option 4: To account for the energy benefit associated with SMI, functionalize 20
5 per cent of the total cost as Generation, which is then classified as both 21
energy and demand. This amount is notional but acknowledges that there is 22
some amount of SMI cost that can be attributed to avoided Generation costs. 23
While the impact is minimal, Option 4 takes a step towards addressing 24
BCOAPO’s and COPE 378’s comments that the classification of SMI regulatory 25
account costs should be aligned with what they characterized as the rationale 26
for SMI. 27

Page 17
Option 5: Instead of functionalizing a portion as Generation, functionalize as 1
100 per cent Distribution and then classify as 95 per cent customer and 2
5 per cent energy. Although this ignores the minor capacity savings associated 3
with the loss-reduction energy savings attributable to SMI, it is simpler than 4
Option 4 calculation-wise and yields a similar allocation to rate classes. 5
BC Hydro will base its COS study on Option 1 while bringing forward Option 5 as a 6
sensitivity. Table 1 demonstrates that SMI does not have a significant impact on 7
COS results as Options 1, 3, 4, and 5 all lead to similar R/C ratios. 8

weighted metering costs discussed in section 2.4.2 of this consideration memo. 14

2.4 Distribution Classification and Allocation 3
2.4.1 Participant Comments 4
Generally, BCSEA expressed support for BC Hydro’s proposed classification and 5
allocation methods for the Distribution system. BCSEA indicated it was unclear on 6
the merits of using customer weights to allocate service and meter related costs. 7
CEC expressed interest in understanding BC Hydro’s proposals in more detail, but 8
made no specific requests for further information and did not suggest any alternative 9
approaches. BCOAPO agreed with BC Hydro’s proposal to classify substations as 10
100 per cent demand and meters as 100 per cent customer, but requested further 11
clarification on the other classification and allocation proposals. BCOAPO’s specific 12
questions and BC Hydro’s responses are shown in section 2.4.2. 13
2.4.2 BC Hydro Consideration 14
In response to CEC, BC Hydro notes that its proposal to sub-functionalize the 15
Distribution system into: substations; primary system; transformers; 16
secondary/services; and meters is based on the advice of its COS consultants and 17
in response to the Commission’s comment in the 2007 RDA that BC Hydro should 18
update its study of its Distribution system.9 The COS consultants suggested that as 19
an alternative to the flawed minimum system and zero intercept classification 20
methods, BC Hydro should consider sub-functionalizing its Distribution system costs 21
and then use professional judgment to separate demand-related and 22
customer-related Distribution costs. This type of methodology is widespread among 23
U.S. electric utilities and distinguishes between plant in service that (1) provides 24
service only to individual customers or customer-related plant in-service from (2) 25

plant in-service that is part of the interconnected distribution network or 1
demand-related plant in-service. (Refer to section 8 of the Workshop No. 4 2
Discussion Guide for more discussion of this methodology). BC Hydro agrees with 3
the COS consultants recommendation. The result is the Distribution classification 4
and allocation summary found at slide 54 of the Workshop No. 4 presentation slide 5
deck. BC Hydro is open to meeting with CEC so that CEC can elaborate on what 6
further details it is looking for. 7
In response to BCSEA, since the October 7, 2014 COS workshop BC Hydro has 8
explored using weighted customer allocators for both services and meters as 9
follows. 10
Services – BC Hydro believes that it will be difficult to develop a weighted allocator 11
with any precision because BC Hydro records the combined asset value of 12
secondary and services in the same asset category and there is risk that the 13
services portion will be over or understated. Refer to BC Hydro’ response to 14
BCOAPO’s comments (sub bullet (d) below). BC Hydro questions the 15
appropriateness of a weighted allocator for service connections as it would skew 16
COS results if the relative costs between different types/sizes of service connections 17
have changed over time. 18
BC Hydro considered whether service related costs should be allocated among all 19
distribution customers or only customers whose service connections have been fully 20
or partially paid for by BC Hydro. BC Hydro reviewed its past practices and 21
determined that: 22
three-phase customers have typically paid for their service connections 23
prior to the late 1990s, most single phase customers were charged a flat 24
$10 connection fee while BC Hydro paid the balance of service connection 25
costs 26
![Page 23: 2015 01 22 Workshop 4 COS Methodology BC Hydro Summary … · 2015-01-23 · October 7, 2014 Workshop No. 4 Cost of Service (COS) Methodology – BC Hydro Summary and Consideration](https://reader033.vdocuments.us/reader033/viewer/2022042404/5f186adf91d8c16412354d33/html5/thumbnails/23.jpg)

Page 20
since the late 1990s, single phase customers have paid standard charges 1
related to their service connections. 2
These observations suggest that BC Hydro’s service related rate base is primarily 3
made up of single phase service connection costs. However, BC Hydro is 4
responsible for maintaining and replacing three phase service connections and 5
these costs are often capitalized and included in rate base. As a result, the 6
service-related rate base likely includes a mixture of single phase and three phase 7
related costs and BC Hydro does not have the data to accurately determine the 8
relative proportion of each. 9
Based on these facts, BC Hydro proposes to allocate service related costs to all 10
distribution customers regardless of the phase level of their service connections. At 11
this time, BC Hydro believes that allocation based on the number of service 12
connections, by rate class and un-weighted by costs, is most appropriate. 13
Meters - Since Workshop No. 4, BC Hydro developed a weighted metering allocator 14
by mapping rate classes to different types of metering and estimating the total 15
installation cost (material, labor, vehicle, testing time). In the case of metering, the 16
use of replacement costs to develop weighting factors is not a significant issue 17
because smart meters were recently installed and the replacement costs will be 18
close to the embedded, book value costs. BC Hydro will continue refining this 19
analysis but currently estimates the following weighting factors by rate class: 20

Page 21
BC Hydro’s responses to specific questions posed by BCOAPO follow below. 1
(a) Can BC Hydro provide additional rationale for proposed 100 per cent demand 2
for primary system and 50 per cent/50 per cent classification of transformers? 3
Of the three major functional areas within the COS (Generation, Transmission and 4
Distribution), the distribution system is the most complex. There are many different 5
types of assets on the distribution system that serve different purposes and have 6
different cost drivers. Other than minimum system/zero intercept methods, which 7
BC Hydro does not favour because they are labour intensive, and are deemed by 8
the COS consultants to be difficult to complete because of issues in collecting the 9
data necessary and the complexity of the studies themselves, BC Hydro is unaware 10
of any technical, quantitative methods to classify Distribution costs. As described 11
above in response to CEC, the COS consultants report that more U.S. electric 12
utilities use professional judgment and are moving towards classifying distribution 13
cost categories as either entirely demand-related or entirely customer-related rather 14
than ‘guessing’ at appropriate splits between the demand and customer 15
classification. 16
BCOAPO is correct that in contrast to substations where the overwhelming 17
jurisdictional approach is to classify 100 per cent demand, utilities classify their 18
distribution primary systems using different mixes of demand- and customer-related 19
costs. BC Hydro’s review of SaskPower’s consultant Elenchus’ 2013 survey of COS 20
approaches suggests a significant presence of demand-related costs which exceeds 21
in value any customer-related investment in primary systems. While the Elenchus 22
survey notes that jurisdictions range from 45 per cent to 100 per cent in classification 23
of primary lines as demand-related, the largest number of responding utilities 24
classify primary lines as 90-100 per cent demand-related.10 In any event, BC Hydro 25

Rate Design Methodologies: A Report Prepared by Elenchus Research Associated Inc.”, page 22. Refer to Nova Scotia Power Inc.’s 2013 Cost of Service Study - Application (Exhibit N-1, Appendix 13.4 (http://www.hydro.mb.ca/regulatory_affairs/electric/gra_2012_2013/appendix_13_4.pdf) for the reference.

Page 22
agrees with its COS consultants that the U.S. electric utility approach is the best way 1
to inform professional judgment. Adoption of this approach results in classifying the 2
primary system as 100 per cent demand because BC Hydro plans the primary 3
system to meet expected peak demand. 4
BC Hydro proposes to directly assign transformer costs and confirms that it is 5
adopting a 50 per cent demand/50 per cent customer classification solely for rate 6
design purposes; to use BCOAPO’s words, the 50 per cent demand/50 per cent 7
customer classification should not impact the total costs allocated to each rate class 8
because the direct assignment approach will be used for purposes of assigning 9
costs among the rate classes. BC Hydro acknowledges that the classification is 10
somewhat arbitrary but is within the range of classification splits adopted by 11
surveyed electric utilities as reported in the Elenchus 2013 survey of COS 12
approaches (with the largest number of responding utilities classify transformers as 13
90-100 per cent demand). 14
(b) How has BC Hydro dealt with unmetered loads or street lighting in its 15
transformer analysis? 16
In the past BC Hydro examined the total load on a given transformer and determined 17
that, on average, about 1 per cent of load could not be accounted for and was likely 18
related to street lighting or other unmetered loads. Based on this, BC Hydro 19
proposes to directly assign 1 per cent of transformer-related costs to street lighting 20
while the other 99 per cent of cost will be directly assigned to the other distribution 21
rate classes using BC Hydro’s proposed Option 1. 22
(c) What are the cost differences between 1 and 3 phase transformers? 23
Since Workshop No. 4, BC Hydro examined this issue in more detail and determined 24
that its draft transformer analysis is appropriate and that there is no need to 25
specifically account for the number or cost of three phase transformers. For 26
example, BC Hydro’s analysis shows that the total cost of 50 kilovolt ampere (kVA) 27

single phase overhead transformers is about $3,300 (materials + labor) while the 1
cost of a 150 kVA three phase overhead transformer is about $9,400 (materials + 2
labor). Since the cost per kVA of a three phase transformer is approximately the 3
same as the cost per kVA of a single phase unit, BC Hydro believes there is no 4
issue with continuing to assume single phase costs for transformers less than 5
100 kW in its direct assignment analysis. 6
Since Workshop No. 4, BC Hydro determined that its transformer Geographic 7
Information System data is reasonably accurate and notes that the data is relied 8
upon for important applications such as outage management. 9
(d) Are the kilometers (km) of secondary/services roughly the same and could that 10
inform the proposed split between these cost categories? 11
Table 2 shows the km length of overhead and underground secondary and services. 12
Table 2 Overhead and Underground Secondary 13 and Services 14
Overhead (km)
Underground (km)
Secondary 15,087 3,680 Services 14,321 6,291
In preparation for Workshop No. 4, BC Hydro developed its 50 per cent 15
secondary/50 per cent services sub-functionalization of this asset category based, in 16
part, by the fact that km shown in Table 2 are roughly equal between secondary and 17
services. Since most customers make Contribution in Aid of Construction-type 18
payments for their service connections and $/km embedded costs for secondary 19
costs are likely higher than services, the 50/50 split may understate the secondary 20
component. However, this is offset by the fact that services are being added to the 21
BC Hydro system at a faster rate than secondary. In recent years, for every km of 22
secondary added approximately 1.8 to 2 km of services has been added. 23
Unfortunately, unless BC Hydro used replacement costs on a $/km basis there is no 24

quantitative method to split this asset category. BC Hydro and the COS consultants 1
have concerns with using replacement costs in an embedded COS study. Given the 2
above issues, BC Hydro continues to believe that a 50 per cent 3
secondary/50 per cent services split remains the best option. 4
(e) What is included in Meters and, where is the cost of the communication 5
infrastructure reflected? 6
In Question 7 of the Workshop No. 4 summary notes, found at Attachment 1 to this 7
consideration memo, BC Hydro was asked to clarify the SMI meter-related costs, 8
and in particular whether SMI-related telecommunication software is captured in 9
meter costs or SMI regulatory costs. BC Hydro responded that these types of costs 10
are capitalized as part of BC Hydro’s rate base rather than deferred in the SMI 11
regulatory account. BC Hydro confirms that communication infrastructure and the 12
associated telecommunication software are not included in the SMI regulatory 13
account and are instead capitalized as part of BC Hydro’s rate base. 14
(f) Has BC Hydro considered a modified Non Coincident Peak (NCP) allocator for 15
demand-related distribution categories? 16
The current methodology for assigning Distribution demand-related costs is based 17
on rate class load profiles for a single year. Each rate class is assigned a 18
1NCP per centage allocator based on its annual peak load as a proportion of the 19
sum of all the rate classes’ annual peak load, which is in line with industry practice. 20
Table 3 provides the 1NCP calculated allocators with the month the peak occurred 21
for each rate class for the last five years. 22

For F2016, BC Hydro proposes to create five-year averages for its load-profile 3
based allocators which would smooth annual weather-related variances. Using the 4
1NCP method, the five-year average allocators are set out in Table 4. 5

In response to BCOAPO’s inquiry regarding consideration of possible modifications 7
of the NCP allocator, BC Hydro calculated a 3NCP allocator,11 both annually and a 8
five-year average, for the F2010-F2014 period as set out in Table 5. 9
11 The 3NCP was calculated for each rate class by adding the three highest monthly peak demands and
dividing by the sum of the three highest monthly peak demands across all rate classes.

To evaluate different NCP approaches, BC Hydro used “bottom up” analysis, which 2
was previously done as part of the Workshop No. 4 presentation (refer to slides 33 3
to 44) where BC Hydro explained why it was not feasible to directly allocate primary 4
system costs to distribution rate classes. The bottom up analysis involves estimating 5
a rate class’s share of feeder peak load for each of the ~1500 distribution feeders. 6
To date, this data does not include the Street Lighting rate class; however, it 7
provides a view of NCP load, by rate class and by feeder, to compare to BC Hydro’s 8
proposed rate class allocator. A calculation is provided in Table 7 which adjusts for 9
the Street Lighting rate class data, assuming a five-year 1NCP allocation for that 10
rate class only. 11

with a flatter load profile (LGS) may be under-allocated costs using a 1NCP 1
allocation. 2
Figure 1 1NCP, 3NCP and 12NCP Comparison 3
BC Hydro proposes to continue with a 1NCP allocator as this most closely 4
approximates BC Hydro’s planning criteria used for the design and construction of 5
Distribution facilities. The 1NCP allocator provides the best representation of 6
diversified class loads on the Distribution system. In BC Hydro’s view use of a 3NCP 7
(or a 12NCP) allocator results in averaging which is inconsistent with how BC Hydro 8
plans its Distribution system and would dilute this estimate away from class peak 9
demand levels. Furthermore, a 1 NCP approach produces results reasonably close 10
to the bottom up analysis conducted across the ~1500 distribution feeders. 11

2.5 Customer Care Allocation 1
2.5.1 Participant Comments 2
BCOAPO asked BC Hydro to confirm whether the meter reading costs shown in 3
Figure 1 of the Workshop No. 4 Discussion Guide were based on all meters or only 4
those without a functioning smart meter. CAPP had reservations with BC Hydro’s 5
approach and argued that the 10 per cent weighting with a revenue allocator will 6
over assign Customer Care costs to Transmission service customers. CEC stated 7
that Customer Care costs should be split on the basis of different service provided to 8
customers and suggested the 90 per cent/10 per cent weighting between number of 9
customers and revenue should be refined if possible. BCSEA asked for clarification 10
on why the 90 per cent/10 per cent weighting should be maintained. 11
2.5.2 BC Hydro Consideration 12
Concerning BCOAPO’s question, the meter reading costs shown in Figure 1 of the 13
Workshop No. 4 Discussion Guide are related to non-communicating meters that 14
require manual meter reading. These do not include meter reading costs associated 15
with the Meter Choices program as those costs (net of the meter reading revenues 16
received from the Meter Choices program) are included in the SMI regulatory 17
account. 18
BC Hydro provided a rationale for the 90 per cent/10 per cent allocator through the 19
‘bottom up’ analysis shown in Figure 1 of the Workshop No. 4 Discussion Guide. In 20
response to CAPP, BC Hydro incurs costs specific to Transmission service 21
customers for Key Account management, billing and management of hourly interval 22
consumption data (Information Technology infrastructure, etc). The 10 per cent 23
allocator assigns approximately $2 million Customer Care costs to Transmission 24
service customers, which aligns with the bottom up analysis of Customer Care cost 25
($2.26 million) shown in Table 8 of the Workshop No. 4 Discussion Guide. 26

proposes methodology changes to certain directives from the 2007 RDA Decision 7
relating to DSM functionalization, BC Hydro Heritage hydroelectric Generation 8
classification, IPP contract classification, Distribution classification and allocation, 9
and Customer Care classification. Refer to Table 8. 10
12 BC Hydro retained SAIC Energy, Environment & Infrastructure in October 2012 (SAIC); SAIC became Leidos
Engineering in September 2013; and the two primary Leidos Engineering consultants became Cuthbert Consulting, Inc. and NewGen Strategies and Solutions, LLC after the COS Methodology Review was finalized in December 2013.

Table 8 Summary of COS Methodology Changes 1
2007 RDA Direction Proposed COS Methodology Change Direction 6 – Functionalize DSM 90% to Generation and 10% to Transmission
Functionalize DSM to 90% Generation, 5% Transmission and 5% Distribution on the basis that while DSM initiatives are primarily undertaken to defer Generation resources, they have some Transmission and Distribution deferral benefits
Direction 5 – Classify Heritage hydroelectric Generation 45% energy/55% demand on the basis that future Resource Smart additions at Revelstoke and Mica Generating Stations are predominantly capacity-related
Use BC Hydro’s integrated system Load Factor calculation based on loads almost entirely served by Heritage hydroelectric supply (the impact of IPPs serving load is removed) resulting in a 55% energy/45% demand split
Direction 8 – Classify IPP purchases 100% energy. BC Hydro is directed to prepare a study for its next RDA that examines and quantifies the capacity benefits associated with IPP contracts
Use an approach where the relative portion of IPP costs allocated to demand is based on the relative portion of capacity benefits from the IPP contract portfolio over IPP costs, resulting in a 93% energy/7% demand split
Direction 4 – Classify Distribution costs 65% demand/35% customer. BC Hydro is directed to conduct a minimum system and zero intercept analysis for inclusion in its next RDA
Sub-functionalize the Distribution system: (1) classify substations and the primary system as 100% demand using NCP allocator; (2) direct assign transformers, with 50% demand/50% customer classification for rate design purposes; (3) classify the secondary system as 100% demand and services as 100% customer and use appropriate allocators; and (4) classify meters as 100% customer and allocate on a weighted customer basis. (The result is about 76% demand and 24% customer split). BC Hydro conducted a minimum study and zero intercept analysis, but has not used the results given the shortcomings outlined at Workshop No. 2 and Workshop No. 4
Direction 4 – Classify Customer Care costs 65% demand/35% customer
Classify Customer Care costs 100% customer as such costs do not vary with demand levels (or energy usage) but only in proportion to the number if customers on the BC Hydro system
There are also two main methodology changes that do not relate to the 2007 RDA 2
COS-related directions referenced above: 3
IPP capital leases - these costs are currently spread across multiple business 4
groups. For COS purposes, they should be considered entirely Generation 5
related. Refer to Attachment 3 to this memo. 6

1. Introduction
Gordon Doyle opened the meeting by canvassing the stakeholder feed-back received as part of the June 19, 2014 COS workshop (Workshop No. 2). He referenced the three documents for the October 7, 2014 workshop (Workshop No. 4): the Consideration Memo concerning Workshop No. 2; the Discussion Guide entitled “Preferred Options and Sensitivity Analysis”; and the slide deck presentation. The central idea behind Workshop No. 4 is to identify BCH’s preferred option for each of the main COS elements, together with other options brought forward for sensitivity analysis. Gord outlined the two main remaining steps in terms of stakeholder feed-back with respect to COS issues: (1) Workshop No. 4 subject matter, whether at the workshop itself or as part of the 30 day written comment period starting with the posting of Workshop No. 4 meeting notes sometime the week of 13 October; and (2) Draft COS study, which BCH anticipates posting to the RDA website sometime during the late November-early December period. Stakeholders would be notified when the draft COS study is posted for comment.
2. Presentation: Issues Previously Canvassed at 19 June COS workshop – DSM Functionalization
Dani Ryan outlined BC Hydro’s preferred option where DSM is functionalized 90% generation, 5% transmission and 5% distribution. The alternative of directly assigning DSM costs to customer classes was reviewed. BCH is concerned that direct assignment results in a significant mismatch between benefits and costs if there was to be direct allocation.

FEEDBACK RESPONSE
1. AMPC asked if the DSM costs are for a particular year. AMPC also asked if the benefits and costs are calculated using a Total Resource Cost test-type methodology.
The costs are a Present Value calculation for the period F2008-F2016. Similar to the Total Resource Cost test the benefits are the avoided cost of energy and capacity supply using BC Hydro’s energy and capacity LRMCs set out in the 2013 IRP, while the costs are those paid by the utility.
3. Presentation: Issues Previously Canvassed at 19 June COS workshop – Heritage Hydro Classification
Dani Ryan identified BCH’s preferred option for classifying BCH Heritage hydro resource costs as using load factor excluding IPPs (Option 1B) resulting in a 55% energy/45 % demand split. Two other options – BCH Integrated system wide load factor including IPPs resulting in a 61% energy/39% demand split (Option 1A) and capacity factor adjusted for book value resulting a 45% energy/55% demand split, were also discussed.
FEEDBACK RESPONSE
1. CEC asked why a capacity factor approach is valid. BCH’s COS consultants, on the basis of jurisdictional assessment, suggested capacity factor as one approach to examine. The capacity factor approach is typically used by utilities whose systems are not hydro-based. The COS consultants recommend a load factor approach for the reasons set out in the slide deck and the Discussion Guide.
2. BCUC staff commented that the capacity factors on slide 12 for Revelstoke and Mica Generating Stations look low.
The capacity factors for Revelstoke and Mica Generating Stations reflect the additions of Revelstoke Unit 5 at about 500 MW and of Mica Units 5 and 6 at about 1000 MW. The size of these additions lowers the capacity factor as these additions come with little energy.
3. BCOAPO asked if Fort Nelson Generating Station is excluded from the system load factor.
Yes, Fort Nelson Generating Station is excluded from the system load factor because the Fort Nelson service area is not part of BCH’s Integrated system.
4. Presentation: Issues Previously Canvassed at 19 June COS workshop – IPP Classification
Justin Miedema set out BCH’s preferred option for classifying IPP costs using IPP costs net of the value of capacity (Option 2). Option 1 (value of energy) and Option 5 (load factor) were discussed. Option 1 and 2 produce virtually identical energy/demand splits (94%/6% and 93%/7% respectively). Option 5 results in a 60% energy/40% demand split which is not reasonable for the many IPP resources that are intermittent and provide little or no dependable capacity.
FEEDBACK RESPONSE
1. West Fraser asked if SOP-related contracts are included in the IPP Cost of Energy.
Revised Response: Yes, the SOP contracts are included in the IPP Cost of Energy.
2. CEC and AMPC questioned how Island Generation is operated vs. how BCH uses it for planning purposes.
Revised Response: Island Generation is a 275 MW combined cycle gas-turbine facility and is treated as a base-load facility for planning purposes (e.g., planning to operate Island Generation at a 90% capacity factor if needed). Island Generation is dispatchable and is displaced if the market is available and economic.
5. Presentation: Issues Previously Canvassed at 19 June COS workshop – SMI Classification
Dani Ryan presented BCH’s preferred option of classifying SMI regulatory account costs as 100% customer-related as this is consistent with other jurisdictions and with how meters generally are classified. Dani explained why BCH rejects Options 2 (100% energy), and outlined another option – Option 3 – consisting of a 30% energy/70% customer split.

FEEDBACK RESPONSE
1. COPE 378 reiterated its opposition to Option 1 on the basis that it does not reflect the rationale for SMI.
BCH commits to carrying forward Option 3 for sensitivity analysis.
Option 3’s 30%/70% alternative was developed by comparing F2016 SMI energy related benefits of about $40 million with total F2016 SMI costs of about $130 million. The primary source of energy benefits is incremental revenue from customers switching to paid service (i.e. reduction in theft). The total estimated costs include depreciation, financing charges and return on equity on SMI related assets along with recoveries from the SMI regulatory account.
2. AMPC reiterated its view that Option 1 is the appropriate way to classify SMI costs as there is nothing conceptual different between SMI and meters generally.
3. BCUC staff requested clear identification of the SMI regulatory account items. BCUC staff remarked that Option 3 is still a ‘live issue’.
The SMI regulatory account was established pursuant to BCUC Order G-64-09 for the purpose of deferring SMI-related operating costs. Attachment 1 sets out the major components of the account along with estimated F2016 balances.
6. Presentation: Issues Previously Canvassed at 19 June COS workshop – Allocation of Generation Demand and Transmission
Dani Ryan outlined that there was good agreement on use of 4CP to allocate Generation demand and Transmission costs, but that there were requests from COPE 378, AMPC and CEC for 4CP sensitivities. Dani presented BCH’s preferred option – continue with the BCUC 2007 RDA decision’s 4CP, and described two 4CP sensitivities and use of 3CP.
FEEDBACK RESPONSE
1. CEC asked why only 5 years data were used for the slide presentation.
BCH has relied on 30 years of data as set out in Workshop No. 2 consideration memo. BCH used 5 years for presentation purposes, and 5 years is representative.
7. Presentation: Distribution: General, Substations and Meters
Justin Miedema introduced BCH’s approach to Distribution. Consistent with the COS consultants’ recommendation, BCH sub-functionalized its Distribution system into: substations; primary system; transformers; secondary system and services; and meters. Consistent with other jurisdictions and the COS consultants recommendations, BCH proposes to classify substations as 100% demand and allocate costs using NCP; and classify meters as 100% customer and alloca te costs on a weighted customer basis.
FEEDBACK RESPONSE
1. BCOAPO asked what type of NCP is used to allocate the Distribution demand costs.
Similar to other electric utilities, BCH uses an annual NCP for its COS.
2. BCOAPO asked BCH to clarify what makes-up meter costs, and in particular whether SMI-related telecommunication software is captured in meter costs or SMI regulatory costs.
These types of costs have been categorized as meter related and are capitalized as part of BC Hydro’s rate base rather than deferred in the SMI regulatory account.
8. Presentation: Distribution – Primary System
Justin Miedema described how the primary system accounts for 49% of Distribution costs and thus was a focus for BCH. BCH proposed to classify the primary system as 100% demand as the primary system is sized to meet the peak demand of customers. BCH examined two options for allocating Distribution primary system costs: Option 1 – direct assignment; and Option 2 – use of NCP. Justin discussed BCH’s concerns with Option 1, and in particular the problems with using replacement costs to value individual primary system feeders. BCH prefers Option 2 as a result.

FEEDBACK RESPONSE
1. CEC asked about use of the term ‘deflation’; is it meant to capture an inflation adjustment or depreciation?
The term is used to refer to depreciation. BCH notes that an inflation adjustment is also required. BCH notes that Hydro Quebec uses replacement costs, estimates the age of the Distribution assets, and uses the Handy-Whitman Index of Public Utility Construction Costs.
2. BCUC staff questioned whether the replacement costs would have to be reconciled with the embedded revenue requirement.
Yes.
3. CLEAResult questioned the data gaps for older Distribution primary assets.
Most utilities have gaps in information in this area as information is not recoded on a feeder-by-feeder basis. There is a significant difference in the quality of information over time; BCH has detailed information for the last 10-15 years or so.
9. Presentation: Distribution – Transformers
Justin Miedema explained that transformers account for 17% of Distribution costs and so were also a focus for BCH.
BCH examined two options for allocating Distribution primary system costs: Option 1 - direct assignment, with a 50% demand/50% customer split for purposes of rate design; and Option 2 – classify as 50% demand/50% customer and use NCP allocate the demand portion and an appropriate customer allocator. BCH prefers Option 1 as it is feasible in the case of transformers to directly assign costs – the costs are a lot less variable than with the primary system as material costs account for about 90% of transformer-related costs.
FEEDBACK RESPONSE
1. BCOAPO asked for further detail as to the proposed 50% demand/50% customer split, and noted that the Discussion Guide indicates that other jurisdictions appear to classify transformers as greater than 50% demand.
The Discussion Guide does note that many utilities classify transformers as 70% or greater demand. However, practice ranges widely and there are utilities that classify transformers as 100% customer. BCH will provide greater detail on the proposed 50% demand/50% customer split.
10. Presentation: Distribution – Secondary System and Services
Justin Miedema outlined that this joint category accounts for less than 15% of Distribution costs. BCH proposes a high level assumption of classifying the secondary system as 100% demand to be allocated NCP; and to classify services as 100% customer and allocated accordingly.
11. Closing Comments
Gordon Doyle reiterated the two main remaining steps in terms of stakeholder feed-back with respect to COS issues.
FEEDBACK RESPONSE
1. BCSEA what portion of the COS costs have the biggest impact.
Heritage hydro Generation classification costs.
2. BCSEA asked how much impact the three options for classifying Heritage hydro Generation costs on R/C ratios.
Looking at Table 5 in the Discussion Guide, there is about a 1% difference.

FEEDBACK RESPONSE
3. CAPP requested that BCH provide the Heritage hydro classification cost in a manner similar to the DSM-related Table 2 of the Discussion Guide, and commented that providing information for other COS elements in a form similar to Table 2 might be helpful.
Attachment 1 contains the requested information for Heritage hydroelectric classification. BC Hydro has also provided information for IPP classification costs in a similar format as IPP costs are the second largest F2013 COS item at $760 million.
Anne Wilson thanked everyone for making the time to participate in the workshop. Meeting adjourned at 11:30 AM.

As noted in section 8.13.1 of the F12- F14 RRA, the cost of energy for IPPs does not 1
include those amounts deemed to be capital leases under IFRS accounting treatment. 2
As a result of the unique treatment of capital lease costs in the RRA, only some of these 3
amounts have been functionalized to Generation in past COS studies. Going forward, 4
BC Hydro believes all of these costs should be considered Generation-related. 5
Table 1 provides an estimate of total IPP costs including the capital lease costs 6
between F2011 and F2016. 7

perpetuating the prior treatment is set out in Table 2. This analysis isolates the impact of 11
the different treatment to IPP capital leases and does not include the impact of BC 12
Hydro’s other preferred methodologies. 13

In its written comments concerning Workshop No. 4, COPE 378 lists seven items 1
regarding a marginal COS approach under the heading “Items you think should be in 2
scope, not currently identified”. BC Hydro is of the view that the issue of whether to use 3
a marginal COS approach to allocate BC Hydro’s revenue requirement is in scope for 4
the 2015 RDA. However, BC Hydro rejects the use of a marginal COS approach for this 5
purpose for the reasons set out in the Workshop No. 2 Consideration Memo. BC Hydro 6
responds to COPE 378 marginal COS items 1, 2, 4 and 7 below. 7
COPE 378 Item 1 – The Workshop No. 2 Consideration Memo states that a marginal 8
COS approach requires a mechanism to force projected revenues under marginal COS 9
to equal the COMMISSION set revenue requirement. COPE 378 states that “another 10
way of saying that is that an explicit method is required to allocate the benefits of low 11
cost heritage power”. 12
COPE 378 Item 2 - “What [BC] Hydro characterizes as a problem with the marginal 13
COS approach is arguably an advantage since the benefits of low cost Heritage power 14
would then be explicitly allocated in a well-considered manner in accordance with 15
BC Hydro and Government objectives, and not obscured in the embedded COS 16
methodology”. 17
BC Hydro response - COS allocations do more than allocate the benefit of Heritage 18
resource energy. A marginal COS study would necessitate development of allocation 19
factors for all Commission set revenue requirements (established using embedded 20
costs), many of which are not Heritage resource energy costs. 21
BC Hydro does not agree that a marginal COS-based allocation of Heritage resource 22
energy accords with B.C. Government objectives: 23
There exists an explicit method for allocating the benefits of Heritage resource 24
energy. As noted in Attachment 3 to BC Hydro’s consideration memo concerning 25
Workshop No. 3, in BC Hydro’s embedded COS study, the costs of both Heritage 26
resource energy and non-Heritage resource energy are allocated to the customer 27

classes on the energy consumption and peak demand of each customer class. As 1
a result, each class receives a share of the benefits of the Heritage resources 2
based on the class’ share of total consumption and peak demand. This method for 3
allocating the benefits of Heritage resource energy existed at the time the B.C. 4
Government legislated the Heritage Contract in perpetuity in 2008,1 and at the time 5
the B.C. Government decided to continue the Heritage Contract provisions formerly 6
found in Heritage Special Direction No. HC2 into Direction No. 7 in 2014.2 7
Policy Action 4 of the 2007 Energy Plan calls for utilities to explore “new rate 8
structures that encourage energy efficiency and conservation” [emphasis added]. 9
This is what BC Hydro has done in respect of the 2008 Residential Inclining Block 10
rate, for example. It is the rate design exercise that uses the results of a COS study 11
that has value in establishing rates that could encourage conservation and 12
efficiency. That is, regardless of the R/C ratio of a rate class, rate design is still 13
required to establish efficient rates. As described in the Workshop No. 2 14
Consideration Memo, a majority of utilities, including so-called “marginal cost” 15
utilities such as New York, design rate structures with marginal cost pricing while 16
allocating revenue requirement on the basis of embedded costs. There is ample 17
evidence that rate design based on embedded COS can provide efficient rates that 18
reflect the cost of new supply. Additionally, marginal COS allocations are not 19
transparent to customers. Rate structure design, where the consequences of 20
consumption decisions are more readily apparent and transparent to customers, 21
provide the means for encouraging energy efficiency and conservation. 22
COPE 378 Item 4 – The Workshop No. 2 Consideration Memo states at page 5 “that 23
there is no evidence that a [marginal COS] approach would yield any meaningful 24
efficiency or conservation gain. We disagree. First, the biggest distortion caused by the 25
embedded cost approach is within the industrial sector, where elasticities are expected 26
to be greater than with the other sectors. It is particularly problematic when embedded 27 1 Order-in-Council (OIC) 849/2008 (November 28, 2008). 2 OIC 097/2014 (March 6, 2014).

cost-based industrial rates attract new electric intensive industry despite the marginal 1
cost implications. Second, [BC] Hydro’s concern that the benefits of the [marginal COS] 2
approach are diluted when rates are adjusted to the total revenue requirement 3
prejudges how that adjustment is done. It can be done in ways that minimize the 4
'dilution' effect”. 5
BC Hydro Response - BC Hydro has not prejudged how marginal COS results would 6
be reconciled with its revenue requirement. The Workshop No. 2 Consideration Memo 7
noted that with an embedded COS, one is starting with real, financially-based utility 8
revenue requirement amounts that can be allocated to customer classes based on 9
actual usage of the utility system resources. In contrast, calculations of Long-Run 10
Marginal Costs on a per kWh, per kW and per customer basis inevitably results in a 11
revenue total that is different from the utility revenue requirement. The Workshop No. 2 12
Consideration Memo at pages 7 to 8 outlines the three methods that are most frequently 13
used to reconcile marginal COS results with the utility revenue requirement that is to be 14
recovered: 15
qualitative inverse elasticity method (also referred to as ‘Ramsey Pricing’) where 16
the customer classes with the highest price elasticity are set closest to marginal 17
COS results, and those with lower price elasticity are set farther from marginal 18
COS results 19
quantitatively-derived inverse elasticity method 20
equal proportion method (sometimes referred to as the ‘equal percentage marginal 21
cost’ or EPMC) where each customer classes’ marginal COS results are adjusted 22
by the same percentage to achieve the overall embedded COS revenue 23
requirement. 24
There is a dilution effect regardless of which method is chosen to reconcile the marginal 25
COS results with the utility revenue requirement. 26

It is not clear which method COPE 378 asserts will result in minimization of the dilution 1
effect. COPE 378 references elasticities, and so perhaps the reference is to the inverse 2
elasticity method. With the inverse elasticity method, the reconciliation process allocates 3
a lower portion of the cost differential between the marginal COS and the embedded 4
revenue requirement to those customer classes with the highest price elasticity levels, 5
thereby setting their allocated COS closer to marginal cost levels than is allocated to 6
those customer classes with lower price elasticity. 7
The inverse elasticity and EPMC reconciliation methods were canvassed by 8
COPE 378’s consultant Dr. Shaffer in his evidence submitted as part of the 2007 RDA. 9
In his 2007 RDA evidence, Dr. Shaffer advocated for the use of an EPMC approach. 10
Dr. Shaffer noted that the inverse elasticity method raises significant fairness issues and 11
that it is difficult to measure customer class price elasticity levels accurately, with the 12
result that this method has been used less frequently than EPMC:3 13
Implementation of this inverse elasticity rule is problematic. Firstly, 14 it offers greatest discounts to those classes of customers that are 15 least willing or able to adjust their electricity consumption 16 regardless of the price. It is not clear that this would be considered 17 an equitable way to distribute the benefit of low cost heritage 18 assets. Secondly, it requires generally accepted, reliable estimates 19 of the price elasticity of demand. While there are many estimates of 20 the price elasticity of electricity demand, and some acceptance of 21 general findings, there is no consensus on specific estimates for 22 specific classes of service or customer. Moreover, the ranges of 23 estimates for different customer classes commonly overlap. They 24 do not indicate a clear justification to allocate more of the discount 25 to one class of customer over another. 26
In response to these circumstances, the California Public Utilities 27 Commission instituted an [EPMC] marginal cost approach. 28 [Emphasis added]. 29
BC Hydro does not believe that customers should be allocated more costs because 30
they are more responsive to the price of electricity solely on the basis of purported 31

higher efficiency levels. Nor does BC Hydro believe that more Heritage resource energy 1
should be allocated to customer classes with allegedly lower price elasticity levels. 2
COPE 378 Item 7 – “The [Workshop No. 2 Consideration Memo] suggests that it would 3
be too complicated to do a [marginal COS] study as we requested (page 8). However, 4
BC Hydro recognizes a [marginal COS] approach would have a significant impact 5
(relative increase) on the allocation of revenue requirements to industrial customers. 6
Thus it is clear that Hydro has information which could be brought to bear on what an 7
[marginal COS] approach would do (and they do have previous studies on this). We ask 8
that BC Hydro provide at least some rough estimates of the impact a [marginal COS] 9
approach would have relative to their embedded analysis approach for all customer 10
classes”. 11
BC Hydro Response – BC Hydro disputes that it has “information which could be 12
brought to bear on what an [marginal COS] approach would do” as it has not conducted 13
a full marginal COS study that would be necessary to make such an assessment. 14
COPE 378 is perhaps referring to page 8 of the Workshop No. 2 Consideration Memo, 15
where BC Hydro noted that there was 2007 RDA testimony from an intervener witness 16
(Mr. Colin Fussell) that under the EPMC reconciliation approach, the Transmission 17
service customer class would see a large increase in rates because they have high load 18
factors and are using proportionately more energy, and that at the time, the marginal 19
cost of energy was considerably higher than the embedded cost.4 BC Hydro also noted 20
there was no testimony on the subject of transmission, distribution or customer marginal 21
costs. 22
To be responsive to COPE 378, BC Hydro provides an additional 2007 RDA reference - 23
BC Hydro’s response to Commission Panel Information Request 1.1.0,5 where 24
BC Hydro provided an example from that time that showed an EPMC reconciliation 25
approach would redistribute the benefits of the Heritage Resource energy, with more of 26

the benefits being allocated to distribution-connected customers and fewer of the 1
benefits being allocated to transmission-connected customers. This result occurred 2
because under the EPMC reconciliation approach the benefit of the Heritage Resource 3
energy would be effectively allocated based on the total costs of serving each rate 4
class, rather than based on the energy consumed by each rate class. Since distribution-5
connected customers have higher total costs than transmission-connected customers, 6
under the EPMC reconciliation approach the distribution-connected customers would 7
receive a greater share of the benefits of the Heritage Resource energy. 8
In the 2007 RDA proceeding, BC Hydro submitted that it is not appropriate to allocate 9
the benefits of the Heritage Resources based on the total costs of serving each rate 10
class, since the Heritage Resources only relate to the Generation function. BC Hydro 11
submitted that it is more appropriate to allocate the benefits of the Heritage Resources 12
based on the energy consumed by each rate class, rather than based on the total costs 13
of serving each rate class. BC Hydro continues to be of the view that the EPMC 14
reconciliation approach if used would not provide an equitable allocation of the benefits 15
of the Heritage Resources. 16
As noted in the Workshop No. 2 Consideration Memo, there are many types of marginal 17
costs associated with electric utility operations, and there are a number of issues with 18
respect to the definition and identification of both the marginal investment and operating 19
expenses necessary to provide electricity to customers, as well as issues with the 20
appropriate definition of marginal customer investment and operating costs. There are 21
also significant issues concerning the marginal COS allocations of certain costs to 22
customer classes that are similar in complexity to the issues necessarily raised in 23
preparing an embedded COS analyses. 24
As one example of this complexity, under a marginal COS approach demand costs 25
would need to be determined and segregated by function into Generation, Transmission 26
and Distribution classifications. Calculating the additional costs necessary in providing 27
an additional kW of demand (or kWh of energy) is not accomplished without the 28

necessity of significant analysis and assumptions: these costs differ depending on the 1
sources and timing of their production (Generation), the distance and sizing involved in 2
their bulk movement from generating facilities to major load centres (Transmission), and 3
the configuration and variety of facilities employed in their continued movement to 4
customers (Distribution, both primary and secondary). 5
Additional issues include: (1) differentiating growth–related projects from sustaining 6
projects for all elements of service; (2) the appropriate time period for the analysis (i.e., 7
inclusion of growth projects with in-service dates over what period of time); (3) the 8
evaluation of regional transmission lines and substation costs as well as distribution 9
substations and trunk-line feeders that vary by area; (4) how the marginal costs of local 10
distribution facilities that vary by customer type and location will be included in the 11
marginal COS analysis; and (5) how would marginal customer costs be determined and 12
differentiated from non-marginal customer costs, including what customer operating 13
expenses are necessary and legitimate marginal costs. 14
Further complicating a marginal COS analysis is the fact that there is not one accepted 15
methodology for conduction marginal COS analyses. As evidence of this, determination 16
of marginal Transmission and Distribution capacity costs has been acrimonious in 17
California despite the fact that the marginal COS approach has been the methodology 18
in California for over 30 years. One method followed by some is termed 19
"Regression/Real Economic Carrying Charge" (RECC).6 RECC uses a regression 20
approach to estimate the marginal investment per kW of peak demand and then 21
amortizes (levelizes) this investment cost by multiplying by the RECC, yielding an 22
annual dollar amount per kW-year which is equivalent in real terms to the investment in 23
dollars per kW. The advocates of RECC state that this approach captures the full cost, 24
rather than the deferral value, for each year of amortization. Another method followed 25
by others is the present worth (PW); the term "PW" is not used here in its usual sense 26 6 An article by Roger L. Conkling entitled “Marginal Cost Pricing for Utilities: A Digest of the California Experience”
in Contemporary Economic Policy (Volume 17:1, January 1999) summarizes, among other things, the competing marginal transmission capacity cost approaches; copy available at http://www.freepatentsonline.com/article/Contemporary-Economic-Policy/54140870.html.

as this method seeks to estimates the opportunity cost of deferring Transmission and 1
Distribution investments due to a change in load growth, taking into account both the 2
timing and magnitude of such changes. 3
As discussed previously in the Workshop No. 2 Consideration Memo, BC Hydro 4
considered the likely necessary costs that would be required as well as the complexity a 5
marginal COS study would entail, and the limited possible benefits that might result from 6
the preparation of a marginal COS study as part of the present effort. BC Hydro 7
concludes that the evidence does not support the value of preparing such a study at 8
present. 9
