BR.NTPC-1
July 20, 2016 Page 1 of 8
Topic: Interim Rate Increase
Reference: Interim Application Dated June 30, 2016; GRA Schedule 3.1-1; Schedule 1
Preamble:
The Corporation is proposing 2016/17 interim rates be implemented on an equal percentage
basis to existing energy rates for all customers in all zones.
Requests:
a) By reference to GRA Schedule 3.1-1 please provide a summary Schedule showing the
major contributors to the revenue shortfall in each of the Zones. Identify the reasons for
the cost and revenue changes that are contributing to the revenue shortfalls by Zone.
Identify any changes in costs arising from change in the head office cost allocation
method, change in accounting standards/policy as well as changes arising from untested
amortization policy or parameters.
b) GRA Schedule 3.1 indicates the required increase for the Taltson Zone to be 38%
whereas the required increases for the Snare and Thermal Zones are 5.3% and 5.1%
respectively. Did NTPC consider a higher interim rate increase for the Taltson Zone
relative to the Snare and Thermal Zones so as the recover the forecast shortfall more
equitably? Please discuss interim rate mechanisms (example cents/kWh varying by
Zone) that may facilitate a more equitable recovery of shortfalls by Zone with supporting
schedules and discuss the pros and cons thereof.
c) Schedule 1 filed as part of the interim application indicates that an across the board
percent increase of 4.8% would result in a much higher cents per kWh increase for
Government customers in communities where the existing rates are already high,
compared with communities where existing rates are relatively low. For example,
general service customers in Nahanni Butte who are currently paying a rate of $2.7551
per kWh would see an increase of 13.22 cents per kWh. Did NTPC consider other
approaches to implementing rate increases within the Thermal Zone without further
exacerbating the existing high rate levels? Please discuss interim rate mechanisms
(example cents/kWh varying by Government and non Government classes) that may
facilitate a more equitable recovery of Thermal Zone shortfalls by rate class with
supporting schedules and discuss the pros and cons thereof.

Please refer to Attachment BR.NTPC-1(a) comparing the 2016/17 shortfall by zone to the
2013/14 shortfall by zone.
Corporate Budgeting Changes since the 2012/14 GRA
For the 2012/14 GRA the budgeting and tracking system for operations and maintenance
expenses did not use FERC accounts. NTPC employed a tracking and budgeting system by
cost center consistent with the Corporations accounting system. For the 2012/14 GRA this was
addressed in response to YK/HR.NTPC-1 and at the hearing. For the 2016/19 GRA, the
Corporation budgets and tracks costs by cost center as well as by function group as shown in
Schedules 5.0 to 5.1-3 and with variance explanations in Schedule 5.2. When comparing the
2013/14 Test Year to the 2016/17 Test Year the variances by function are mainly attributed to
the different forecasting methods. The Corporation also created a customer service division and
consolidated the transmission and distribution costs. These changes are reclassified from direct
plant costs to common costs.
Variance explanations are provided by zone below.
Snare Zone
The Corporation has reclassified operations and maintenance expenses between plant and
regional/corporate costs. These budgeting changes contribute to the majority of the $0.880
million increase in common operating and maintenance costs and the marginal increase to plant
operating and maintenance costs. Please refer to Chapter 5 of the 2016/19 GRA for further
explanation of changes in operating and maintenance expenses. Production fuel costs have
increased due to the increased base load diesel generation in Yellowknife. Fixed asset
amortization and return on Rate Base for plant and common costs increased as a result of
investment in gross plant and the 2016 Amortization Study. Deferred charges amortization has
increased due to costs incurred to maintain the water licences at Bluefish and Snare. The higher
annual costs relate to increased environmental monitoring at Bluefish dam and increased costs
related to dam inspections as a result of dam safety reviews, required flood surveys and
increased costs relating to annual dam testing and inspections.

The sales impact on revenue to cost ratios, as discussed in Chapter 2 of the GRA, on the Snare
system, are related to decreased sales to the wholesale customer and the industrial customer.
The residential class is forecast to have slightly higher sales in 2016/17 compared to 2013/14.
Sales to general service customers are forecast to be somewhat lower in 2016/17 compared to
2013/14. Common cost deferred amortization expense has increased due to increased
regulatory reporting charged to the regulatory deferral account and the employee future benefits
deferral account increasing because of a new actuarial study and higher than forecast employee
turnover.
Taltson Zone
The Corporation has reclassified operations and maintenance expenses between plant and
regional/corporate costs. This is one reason for the $0.808 million increase in common
operating and maintenance costs and the marginal increase to plant operating and maintenance
costs. Please refer to Chapter 5 of the GRA for further explanation to changes in operations and
maintenance expenses. Fixed asset amortization and return on Rate Base for plant and
common costs increased due to investment in gross plant and the 2016 Amortization Study.
The sales impact on revenue to cost ratios as discussed in Chapter 2 of the GRA, on the
Taltson zone, are forecast to be relatively flat for 2016/17 compared to 2013/14. Decreases in
sales to the wholesale customer are forecast (1.4 GWh lower in 2016/17 compared to 2013/14
forecasts). These lower forecasts for wholesale sales in 2016/17 are consistent with the
decrease in actual sales from 2013/14 to 2014/15. Modest growth is forecast for residential
sales (0.5 GWh) and general service sales (0.4 GWh) reflecting higher average use per
customer. Common cost deferred amortization expense has increased due to increased
regulatory reporting charged to the regulatory deferral account and the employee future benefits
deferral account increasing because of a new actuarial study and higher than forecast employee
turnover.
Thermal Zone
The Corporation has reclassified operations and maintenance expenses between plant and
regional/corporate costs. This is one reason for the $1.927 million increase in common
operating and maintenance costs and the reduction to plant operating and maintenance costs.
Please refer to Chapter 5 of the GRA for further explanation to changes in operating and
maintenance expenses. Production fuel and purchased power prices are lower due to lower fuel

prices. Fixed asset amortization and return on Rate Base for plant and common costs increased
due to investment in gross plant and the new amortization study. Deferred charges amortization
has increased as a result of costs incurred for engine overhauls. In particular for 2016/17
overhauls in Inuvik are higher as the larger units are due for major overhauls.
The sales impact on revenue to cost ratios as discussed in Chapter 2 of the GRA, in the
Thermal zone largely reflect decreased sales units to general service customers (3.7 GW.h
lower compared to 2013/14 forecasts). These decreases are consistent with actual decreases
between 2013/14 and 2014/15 and reflect lower average use per customer. Sales decreases for
residential customers also reflect somewhat lower average use per customer. Sales decreases
for street lighting customers reflect the conversion of streetlights from mercury vapour and high
pressure sodium lamps to LED. Common cost deferred amortization expense has increased
due to increased regulatory reporting charged to the regulatory deferral account and the
employee future benefits deferral account increasing because of a new actuarial study and
higher than forecast employee turnover.
Impact of head office cost allocation method
Please refer to Attachment BR.NTPC-1(a) that shows the change in head office allocation
between Test Years.
Impact of accounting standards/policy
As discussed in Chapter 5 of the 2016/19 GRA, the Corporation has added one full time
equivalent position, a Management Accountant for regulatory and PSAS accounting. The costs
for the transition to Public Sector Accounting Standards are included in deferred expenses and
discussed on page 11-48 of the 2016/19 GRA. These costs are also reflected in Schedule 11.5
of the 2016/19 GRA.
Impact of Amortization Study
Table 6.2 of the GRA shows the changes to plant amortization expense from the 2013/14 Test
Year to the 2018/19 Test Year. Table 1 below shows the same analysis but for the 2016/17 Test
Year.

Table 1
Amortization Expense Change from 2013/14 Test Year to 2016/17 Test Year ($000s)
The changes that result from the 2016 Amortization Study is the total of the Increased
Amortization Rates, Negative Salvage Collection and True-Up Provision change. These three
items total $0.236 million on a corporate wide basis. The amortization expense increased by
$1.938 million between the Test Years and the Amortization Study accounts for 12% of the
change. The majority of the change is a result of asset additions.
(b)
The Corporation filed revised versions of the GRA schedules with the Board and interveners on
July 12, 2016. The revised rate version of Schedule 3.1-1 2016/17 Revenue Requirement by
Zone shows the average percentage rate increase required to be 5.6% for the Snare zone;
30.8% for the Taltson zone and 5.9% for the Thermal zone.
The Corporation notes that the breakdown of Revenue Requirement by zone is provided solely
for illustrative purposes as part of the 2016/19 Phase I Application. Cost allocations are still
subject to change and will be reviewed as part of the next Phase II General Rate Application.
Changes to cost allocation methods will change the revenue to cost coverage ratios for each
zone. In particular, the allocation of Hydro region costs between the Snare and Taltson zones
and the allocation of the Corporations corporate common costs among all zones is a matter for
review during the Corporations Phase II Application. The Corporation also notes there are a
number of directives included in Board Decision 7-2016 related to the Corporations 2014 cost
of service study. Changes to cost of service methods as a result of completing the Boards cost
of service directives would change the required rate increase percentages for each zone. As a
result, the Corporation considers that the zone based information provided as part of the Phase
I filing should be considered illustrative and primarily provided for information purposes at this

time. Revenue to cost coverage ratios will be subject to change as part of the review of the
Phase II General Rate Application.
The Corporation believes that its proposed interim rates are equitable and notes the following:
1. The Corporation is seeking to transition customers to an overall Revenue Requirement
that is approximately 13% higher than current rate levels. Over a three year period this
requires average rate increases of slightly more than 4% per year. The Corporations
2016/17 interim rates were developed to provide a first step toward the required revenue
increases keeping in mind the rate stabilization fund refund rider approved for
implementation in 2016 offsets some of the increase to base electricity rates.
2. The proposed increases of 4.8% to the energy rates are lower than the total average
2016/17 percentage increase required for each zone as shown in Schedule 3.1-1
revised July 12, 2016 of 5.6% for the Snare zone; 30.8% for the Taltson zone and 5.9%
for the Thermal zone. On that basis, no zone is forecast to pay rates that result in
revenues higher than the forecast Revenue Requirement for 2016/17.
3. The Corporation is following common regulatory practice as other electric utilities have
received approvals for interim rate increases on an equal percentage basis:
a. The Manitoba Public Utilities Board recently approved a 3.36% interim rate
increase to existing rates for all of Manitoba Hydros customer classes.1
b. The Alberta Utilities Commission approved ENMAX Power Corporations
application for an interim rate of 3.19% to be applied to all rate classes on an
across-the-board basis effective January 1, 2015. In its Decision, the AUC noted
in part that this method is simple and cost effective to apply.2
4. The 2015 GNWT guidelines limited rate increases due to rebalancing to no more than
3% until the time of the next Phase II GRA.3 If the Corporation were to increase rates for
the Taltson zone by 7.8% (that is, 3% higher than the average rate increase sought
Corporation-wide), it would reduce the rate increase required for the Snare and Taltson
zones by only a very small amount to 4.55% to generate the same interim rate revenues

in 2016/17. The proof of revenue for this scenario is provided in Attachment BR.NTPC-
1(b). In the Corporations view there is little impact on rates for the other zones, and this
approach complicates the Interim Rate Application and is more difficult to explain to
customers.
NTPCs long-standing rate strategy has been to work towards a 90-110% range for revenue to
cost ratios for all zones. In targeting the 90-110% RCC, NTPC balances other rate design
criteria such as gradualism and predictability for customers. As a small utility with small rate
zones, Revenue Requirement changes that might not materially impact revenue to cost ratios in
other jurisdictions can have large impacts for NTPCs rate zones. In addition RCC ratios are not
static over time. For example, sales growth forecasts, investment in hydro and transmission
facilities; major overhauls requirements and other factors are not uniformly distributed across
zones and may change the RCC ratios significantly. The Corporation notes that many other
utilities use a range of reasonableness for revenue to cost coverage ratios:
Manitoba Hydros long-term target is to have all class revenue to cost coverage ratios in
the range of 95% to 105%.4
SaskPower has a revenue to revenue requirement target ratio of 0.95 to 1.05.5
The Yukon Utilities Board has previously approved a target revenue to cost coverage
range of between 90% to 110%.6
On this basis, the Corporation believes its proposed interim rates are equitable and consistent
with good utility practice.
(c)
The Corporation prepared its Interim Rate Application based on the criteria described in the
Application. For the reasons noted in response to BR.NTPC-1 (b), the Corporation believes it
proposed interim rates are equitable. Further, the Corporation notes that Guideline 3 from the
2015 GNWT guidelines states that realignment of community based rates for Government
customers shall be deferred until the next Phase II GRA. Guideline 3 is also designed to

achieve a zonal based government rate as opposed to the current community based
Government rates. In the Corporations view Guideline 3 is not intended to make Government
rates equal non-Government rates by zone. Guideline 3 from the 2010 GNWT Rate Policy
Guidelines states that government customers can have higher electricity base rates than non-
government customers in the same community for the same type of service, but not lower than
non-government customers. The Corporations proposed interim rate design is consistent with
both of these guidelines and will result in government customers continuing to pay rates that are
the same or higher as other customers in the same rate community.
For illustrative purposes, the Corporation prepared an analysis of a potential equal cent/kWh
increase where there is currently a large variation between government and non-government
rates within a zone. The largest energy rate variations between government and non-
government rates occur in the Thermal zone. The difference between government and non-
government rates in the Snare and Taltson zones are relatively small on a cents/kWh basis. An
interim rate increase of 4.36 cents per kWh for all government customers would result in the
same interim rate revenues as the Corporations proposed 4.8% increase to all energy rates.
The analysis is provided in Attachment BR.NTPC 1(c).

Topic: Revenue Forecast
Reference: Interim Application Dated June 30, 2016; GRA Schedule 2.1-1 to 2.1-3;
Schedule 1
Preamble:
Total forecast sales for 2016/17 are lower relative to the 2013/14 Test Year forecast (14.3
GWh), with an average annual decline in sales of 1.5%. Revenue at existing rates has
decreased by $4.6 million as shown in Table 2.3 in the GRA which is due to the reduction in
sales.
Requests:
a) Schedules 2.1-1, 2.1-2 and 2.1-3 generally reflect declining use per customer for
residential and general service customers in all Zones since 2013/14 actual with some
modest increases forecast for the test years. Please indicate whether some or all of the
declines in sales that occurred in 2014/15 and 2015/16 may be attributed to the
economic impact of the oil price decline in 2014/15.
b) Does NTPC expect residential and general service use per customer to improve to the
levels that existed during 2013/14 and preceding years; if so to what extent and when?
Provide reasons.
c) Please provide the experienced and forecast real GDP growth rates for the NWT for the
period 2013 to 2019. Identify the source documents used for this purpose.
d) To the extent some of the decline in sales in the test period relative to 2013/14 may be
due to an economic downturn, please provide the forecast use per customer for the test
period using the regression analysis described under response to directive 32, but giving
due recognition to the impact of the economic downturn. (example: use of GDP growth
as a second independent variable or, use of dummy variables to represent the economic
downturn)
e) Schedule 2.1-1 indicates the Snare Zone wholesale sales declining from 168.1 Gwh in
2013/14 to 163.4 Gwh in 2014/15 and continuing at this same level for the entire test

period. Please explain why NTPC is not expecting wholesale sales to recover following
2014/15 having regard to GDP growth expectations for Yellowknife.
f) Schedule 2.1-2 indicates the Taltson Zone wholesale sales declining from 2013/14
levels into 2014/15 and 2015/16 and then showing moderate improvement in the test
period but still below 2013/14 levels. Please provide the rationale and support for the
above noted pattern of sales for the Taltson Zone.
Response:
(a) through (f)
The Corporations load forecast was prepared consistent with the methods requested by the
Board in Decision 1-2013. The discussion of the methods used in preparing the load forecast for
the Test Years is provided in Chapter 2 of the 2016/19 General Rate Application. The
Corporations response to the Boards directive with respect to the Corporations load forecast
method is provided in Chapter 13 of the Application. The Corporation believes its load forecast
as provided in Chapter 2 of the Application is reasonable for the purposes of evaluating the
2016/17 Interim Rate Application. The Corporation notes that for the purposes of the Interim
Rate Application, the 2016/17 sales forecast is most relevant. Sales forecasts for the future Test
Years can be reviewed as part of the full 2016/19 General Rate Application proceeding.
Detailed forecast and actual GDP data by year is not readily available for the NWT. Given the
methodology changes suggested by the Board and the complexity to complete the changes, the
Corporation feels it is more suitable to discuss different load forecast methodologies in the
context of the 2016/19 GRA which would have implications on all three Test Years as opposed
to the 2016/17 Interim Rate Application. However the Corporation can provide some additional
information in this response to assist with the understanding of the 2016/17 Test Year load
forecast.
The Corporation notes that the 2013/14 actual sales represented the highest total sales levels
between 2009/10 and 2015/16. The Corporation has observed consistent year over year
decreases in average use per customer from 2013/14 through 2015/16. Table 1 summarizes the
actual and forecast residential, general service and wholesale sales for 2009/10 through
2018/19.

Table 1:
Residential, General Service and Wholesale Sales (MWh)1
Based on a review of the actual historic sales information, the Corporation is of the view that
2013/14 should not be considered a baseline or normal year, but actually represented a year
of unusually high sales.
Using the load forecast methods requested by the Board in Decision 1-2013, the Corporation is
forecasting a small recovery in total sales in 2016/17 compared to 2015/16. However, the
Corporation is not anticipating sales to return to 2013/14 actual levels. Additional information
that the Corporation believes supports the forecast of only a modest recovery in sales in
2016/17 compared to 2015/16 includes:
1. 2013/14 actually represented the highest total sales volumes for the five year period
from 2009/10 through 2013/14. For the years 2010/11 through 2012/13 total sales were
relatively flat, with 2013/14 representing a noticeable increase over previous sales
levels.
2. The GNWTs 2016 fiscal framework notes that the NWT is facing a range of economic
challenges. The economy is currently fragile and thus extremely susceptible to
pressures from outside the territory.2
1 Note: 2009/10 through 2014/15 are actual sales. 2015/16 includes 11 months of preliminary actuals.
2016/17 is the test year forecast included in the Corporations 2016/19 General Rate Application. 2 Government of the Northwest Territories 2016 Fiscal Framework. Available:

3. A 2015 presentation from the Conference Board of Canada indicated 10-year average
GDP growth of approximately 1% per year from 2015 to 2025.3
4. The GNWT bureau of statistics released a report in May 2016 that showed modest
growth in territorial chained GDP in 2015 compared to 2014.4 However, the following
should be noted in considering this information:
a. The report is based on preliminary information. Final 2015 economic accounts
information is not expected to be available until November 2016.
b. Much of the growth in territorial GDP was driven by an 18.3% GDP increase in
the construction sector. Construction at the Gahcho Kue diamond mine in 2015
contributed to the increases in the construction sector.
c. The preliminary 2015 figures show a 2.9% decline in the Mining, quarrying and
oil and gas extraction figures. This is the largest single sector in the Northwest
Territories economy.
d. In December 2015, De Beers Canada announced the closure of its Snap Lake
diamond mine.5 The preliminary 2015 GDP estimates will not reflect the full
annualized impact of the closure of the Snap Lake diamond mine.
5. Territorial population growth estimates are low, less than 0.5% between 2015 and 2016.6
Based on these considerations, the Corporations view is that the modest recovery in sales for
2016/17 over 2015/16 is reasonable for the purposes of interim rates for 2016/17. The
Corporation does not believe it is appropriate or reasonable to forecast a return to 2013/14
sales levels for 2016/17 for the purpose of setting interim rates. The best information the
Corporation has available is that 2013/14 had unusually high sales due to a colder winter and
that economic recovery in the NWT will be slow for some time.

Reference: June 30, 2016 Interim Rate Application [Page 4 of 5]
Preamble:
While NTPC has provided a very high level summary (4 bulleted points on page 4 of 5) of key
changes since its 2013/14 Test Year, the TGC desires additional information to assess the
nature of contentious issues and extent to which such items should be included for recovery
through interim rates.
Requests:
a) Please provide a table which shows the major cost drivers (costs greater than +/-
$250,000 or 10%) which contribute to the increase (decrease) in the 2016/17 Revenue
Requirement relative to the most recently approved 2013/2014 Phase 1 GRA in Decision
1-2013 dated January 21, 2013. For clarity, the TGC request is for details at the
functional level for non-fuel O&M costs as well as costs related to capital, deferred costs
and deferral accounts.
b) To the extent possible, please provide the information requested in a) above on a zonal
basis.
c) To the extent one rate zones cost increases contribute to a greater portion of the
projected overall corporate shortfall of $8.157M, please explain why an across-the-board
4.80% interim rate rider is appropriate.
Response:
(a) and (b)
Please refer to BR.NTPC-1(a). For functional level non-fuel O&M costs please attached
