Reasons for Order
1.
Introduction
[1] This is an application under
the
Electric Power Act, R.S.P.E.I. 1988, Cap. E-4 (the
"Act"),
by Maritime Electric Company, Limited (the "Applicant", "Maritime Electric" or
the "Company") seeking, among other things, an order or orders of the Island
Regulatory and Appeals Commission (the "Commission") approving an increase in
the Company's basic rates of 3.35% effective July 1, 2006.
[2] The application in
this matter was filed on January 31, 2006 and publicly noticed in the
Province's daily newspapers and on the Commission's website. In response to
the notice, the Commission received a formal intervention from the Prince
Edward Island Power Company Limited ("PEI Power") and also received a comment
from a member of the public generally opposing the application and a request
from a member of the public to make a presentation. The latter request was
granted but a presentation was not forthcoming.
[3] The formal
intervention filed by PEI Power concerns itself with an application by
Maritime Electric for approval of a wind power purchase agreement with the
P.E.I. Energy Corporation and the P.E.I. Government. That application is being
dealt with separately by the Commission under docket UE21007. PEI Power has
also intervened in that case.
[4] Given that PEI
Power's interventions in both cases are virtually identical, the Commission
will consider the intervention within the context of docket UE21007.
2.
The Application
[5]
Maritime Electric seeks an
Order or Orders of the Commission:
-
confirming Maritime
Electric's rate bases for the years ended December 31, 2003- 2005 at
$188,526,407, $197, 685,922 and $202,501,831 respectively, for establishment
of its projected rate bases at $243,638,600 for the year ended December 31,
2006 and at $258,185,100 for the year ended December 31, 2007;
-
approving an
increase in basic rates of 3.35% for July 1, 2006 together with the general
Rules and Regulations which relate to those rates for the period July 1,
2006 to December 31, 2007.
3. Discussion & Findings
3.1 Introduction
[6] The application
before the Commission involves an assessment of several issues, including the
Company forecast of sales and expenditures as well as other matters directly
related to the proposed rate increase. In the discussion that follows, the
Commission will review these issues and render its findings.
3.2 Sales Forecast
[7] The sales forecast
is critical in determining many of the Company's operating expenses
particularly those relating to energy purchases. A sales forecast that
underestimates growth can, for example, result in a requirement for rates that
is higher than necessary and revenue surplus to the needs of the Company.
[8] Prior to
deregulation in 1994, the Company's sales forecast was based on an economic
model that used historical sales, customer data, population statistics,
provincial economic indicators and other related data. This rate application
reintroduces these sales modeling techniques; however only short term sales
forecasts are provided. Short term energy sales forecasts are based on a
two-year average growth rate calculation and the rate of year-to-date growth
over the previous year-to-date growth.
[9] Table 1 shows
actual and forecast sales levels, by rate class, from 2004 to 2007.
Table 1
[10] To assess the
reasonableness of the forecast, the Commission has looked at recent
actual-to-forecast results, the modeling approach used and the inputs and
assumptions used in the model. Past forecast information was not available to
the Commission during the period of deregulation. The 1993 general rate
case—the last review of the Company's rates prior to deregulation—concluded
that there was a positive trend on the part of the Company's forecasting
accuracy.
[11] Table 2 compares
the most recent forecast-to-actual results.
Table 2
[12] Historically,
forecast results have tended to err on the low side of actual results. In the
Commission's view, however, the above shows reasonable accuracy in the
Company's recent forecasting techniques and provides the Commission with
confidence in the forecasts for 2006 and 2007.
[13] Maritime Electric
has filed with the Commission its Demand Side Management Plan, Phase 1 for the
period 2006-2010 as required by the
Renewable Energy Act. This
Act calls for a
5% reduction, by 2010, in the intensity of peak demand as measured in 2004.
The impact of this plan is not expected to impact the revenue forecast
contained in this application, but will need consideration in the future.
[14] The Commission finds that the
projected growth rate of 1.4% in 2006 and 2007 appears reasonable. Although
lower than the forecast general growth in the Canadian economy of 3.1% as
reported in April by the Bank of Canada, it is more in line with local P.E.I.
economic conditions. The Commission accepts the Company's sales forecast of
1,002,623 mWh for 2006.
3.3 Operating Expenditure Forecast
[15] The operating
expenses of Maritime Electric are made up of production, transmission,
distribution and administrative costs. Production costs—or costs associated
with energy supply—represent the largest component of the Company's expenses
and overall revenue requirement. These expenses include energy costs to be
procured under pre-negotiated energy purchase contracts as well as
expenditures associated with the Company's generation facilities in
Charlottetown and Borden. Energy purchases from NB Power fall under three
contracts: the Point Lepreau Unit Participation Agreement, the Dalhousie Unit
Participation Agreement and an Energy Purchase Agreement. Both unit
participation agreements extend for the life of the generating stations while
the Energy Purchase Agreement is a short-term supply agreement that expires on
October 31, 2006.
[16] A summary of
energy supply costs is shown below.
Table 3
[17] The energy cost
per source varies by contract and by the fuel source. While some costs are
stable and predictable, many are not.
[18] Energy supply
constraints with ever increasing demand for energy are causing rising energy
costs throughout the marketplace. The rising price of crude oil is a good
example of the affects of supply constraints with increasing consumer demand.
This is a concern as it may have an impact on new energy supply contracts that
will take effect in the fall of 2006.
[19] Transmission expenses relate
to those facilities that make up the Company's bulk energy delivery system,
from the submarine cables to the inputs in the Company's distribution system.
Distribution expenses cover the day to day operating costs of the Company's
distribution system and include expenses such as planned maintenance,
breakdown and forced outages and equipment failure. General expenses include
internal and external costs associated with the overall operation and
management of the Company.
[20] A summary of these
expenditures, by major category, follows:
Table 4
[21] Table 4 shows
overall cost increases of 2.92% in 2006 and 2.98% in 2007.
[22] Within the context
of published economic forecasts for 2006 and 2007, the Company's forecast
appears reasonable. The Commission has, as well, spent considerable time
reviewing detailed budget data submitted in response to staff interrogatories
and has satisfied itself that forecast expenditure levels are reasonable and
prudent.
3.4 Rate of Return
[23] The Commission is
guided in determining the allowable return on average common equity rates by
the
Electric Power Act which requires that the return be just and reasonable.
Considerable jurisprudence in this area clearly directs that the return must
be fair to both the consumer and the shareholder.
[24] Maritime Electric
maintains that the rate of return must:
-
Earn a return on the value
of its property commensurate with that of comparable risk enterprises;
-
Maintain its financial
integrity; and
-
Attract capital on
reasonable terms.
[25] Maritime Electric
is proposing a return on average common equity in the range of 10.0% to 10.5%.
The Company states it will continue to strengthen its capital structure by
increasing its common equity ratio to 45% from 42.69% in 2006 by the retention
of earnings.
[26] A major input factor in the
selection of return on common equity rates is business risk. As described in
the rate application, business risk comes in the form of:
[27] The Company
concludes that it is a higher risk utility than the other two investor-owned
Atlantic Province electric utilities, Newfoundland Power and Nova Scotia
Power. The Company provided the following actual return information for both
investor-owned electric utilities:
Table 5
[28] The Commission has reviewed
the Company's submissions on this matter and agrees that the Company operates
with a higher degree of business risk than other investor owned utilities in
Atlantic Canada. This is due, in part, to the relative small size of the
Company. In our view, this risk is, however, mitigated somewhat through the
operation of the Energy Cost Adjustment Mechanism, which is discussed in more
detail below.
[29] The Commission finds that a
rate of return on average common equity of 10.25% is just and reasonable. This
is viewed by the Commission as an upper limit or the maximum allowable return.
3.5 Deferred Costs Recoverable from
Customers
[30] Section 47
of the
Electric Power Act reads, in part, as follows:
Transitional rates and
terms of service |
47.
(1) On and after January 1,
2004, Maritime Electric Company, Limited shall provide service in the
province at the rates, tolls and charges, and on the terms and conditions of
service, that were established and in effect under the former Act and the
former regulations immediately before January 1, 2004 until such time as
those rates, tolls and charges, and those terms and conditions of service,
are altered or modified under this Act.
2003,c.3,s.23. |
Annual report |
(2)
Prior to March 1, 2004, Maritime Electric Company, Limited shall provide an
annual report to the Commission for the calendar year beginning January 1,
2003 that complies with the requirements of section 15.
2003,c.3,s.23. |
Submission of
proposed rates, tolls and charges |
(3)
Prior to May 1, 2004, Maritime Electric Company, Limited shall make a
submission to the Commission under section 20 for the review and approval of
its rates, tolls and charges.
2003,c.3,s.23. |
Recovery of
deferred costs, interest and unamortized expenses |
(4)
When approving or determining and fixing the rates, tolls and charges of
Maritime Electric Company, Limited pursuant to a submission made under
section 20 in accordance with subsection (3), or in accordance with any
later application made in accordance with section 20, the Commission shall
allow Maritime Electric Company, Limited |
|
|
(a) to
recover, over such period of time and on such terms and conditions as the
Commission considers just and reasonable,
|
|
|
|
(i) the
deferred costs that Maritime Electric Company, Limited would have been able
to recover under the former Act and the former regulations, |
|
|
|
(ii) the unamortized portion
of any deferred cost incurred before January 1, 2004 by Maritime Electric
Company, Limited in respect of any power purchase agreement, and |
|
|
|
(iii) a reasonable return on
the unrecovered deferred costs referred to in subclauses (i) and (ii); and
|
|
|
(b) to
recover, as an annual expense, the amounts payable by Maritime Electric
Company, Limited pursuant to any power purchase agreement Maritime Electric
Company, Limited has entered into before January 1, 2004 that continues in
force on and after that date.
2003,c.3,s.23. |
[31] Commission Order
UE05-01 approved the recovery of deferred costs in the amount of $1,500,000
in 2004 and $2,500,000 in 2005. This leaves $16,783,600 yet to be recovered
from rates. Maritime Electric is requesting that a further $1,500,000 be
recovered in 2006 and $1,300,000 in 2007. These are the amounts included in
the proposed rates.
[32] Although the
Commission has not, to date, defined the time period over which the remainder
of the deferred account must be amortized or recovered through rates, the
Commission believes that it is time to do so. We will, however, give the
Company an opportunity to make a submission before doing so. The Commission
will order the filing of such a submission before the end of 2006. The
proposed amount for 2006 will, however, be allowed. A decision on the 2007
amount will be deferred pending the filing of the above submission.
3.6 Proposed
Rates
[33] A summary of current and
proposed basic rates is summarized in Table 6.
Table 6
[34] Maritime Electric
states that the proposed 3.35% basic rate increase will be largely offset on
July 1, 2006
due to the effects of the Energy Cost Adjustment Mechanism ("ECAM"). The
Company states that the overall impact on a Rural Residential customer on July
1, 2006 using 650kWh per month (including GST) is a total increase of 1.6%.
The following table illustrates the proposed rate increase for the average
rural residential customer.
Table 7
[35] In 2004, the
Company applied for, and received Commission approval of, the present ECAM.
The ECAM provides a mechanism that automatically adjusts monthly billings to
customers to reflect changes in defined energy related costs.
[36] Without a mechanism to adjust
for variations in energy supply costs, the Company's earnings would, in
theory, fluctuate beyond reasonable ranges, resulting in the need for frequent
Commission hearings. Maritime Electric maintains that the ECAM, in its present
form, provides stability to the Company resulting in reduced basic rates. For
example, an increase or decrease in energy costs of $2,000,000—or
approximately 3%—would see a variation of approximately 15% in the Company
earnings. According to the Company, debt holders and shareholders would demand
higher returns to offset this volatility. Maritime Electric maintains that the
stability associated with this adjustment mechanism eliminates the need for
frequent and costly rate hearings.
[37] Commission Order
UE05-05, dated March 16, 2005, approved the interim and transitional ECAM
currently in effect. Order
UE05-06, dated June 24, 2005, ordered the
replacement of the current ECAM with one containing fewer accounts. The
transition to a new ECAM was to take effect on
July 1, 2006.
[38] During 2004 and 2005, the
ECAM was the subject of an independent study carried by consultant John
Murphy. The Murphy study recommended a number of changes to the ECAM which
were commented upon by the Company. In summary, Murphy recommended:
-
That certain expense
classifications that should be excluded from the ECAM; and
-
that volume level changes
in total purchased power should be excluded from the ECAM.
[39] Maritime Electric
now requests that the Commission delay any changes to the ECAM pending receipt
and review:
-
of a depreciation study and
cost allocation study ordered by the Commission, by Order
UE06-02, to be
filed in the summer-fall of 2006;
-
of new energy supply
agreements; and
-
of the refurbishment costs
associated with the Point Lepreau nuclear generating station.
[40] The Commission
agrees with Maritime Electric that the pending studies will have implications
on the ECAM. As a result, the Commission will, for now, order the continuation
of the interim and transitional ECAM currently in effect.
[41] The Commission has reviewed
the forecasted impact the monthly ECAM charges will have on consumer
electricity charges for 2006 and 2007. Currently, customers are enjoying the
benefits of an ECAM adjustment that reduces monthly customer bills. The main
reason for this lies in the present energy supply contracts negotiated several
years ago when energy was less expensive and denominated in US dollars. The
appreciating Canadian dollar has assisted in reducing the costs of purchased
energy.
[42] It is unlikely that Maritime
Electric will, in future, be immune from rising energy costs experienced by
all jurisdictions. New energy supply contracts will no doubt be more expensive
than current agreements and will be based on a higher valued Canadian dollar.
[43] The Commission is concerned
about the impact of rising ECAM adjustments and the rising balance of the ECAM
account due to the 18 month amortization of energy costs. Deferring energy
costs to a future period when costs are rising will place further burden on
customers. The Commission is of the view that utility energy costs should be
recovered within the year the energy is used. As an alternative, the
Commission has considered an ongoing 12 month amortization period. This
results in a higher recovery of ECAM charges as shown by the following figure
which compares amortizations periods of 18 months and 12 months, commencing in
January of 2007. The figure depicts the change in the bill of a residential
customer who consumes 650 kWh per month.
Figure 1
[44] The ECAM balance
to be recovered from customers using the currently authorized 18 month
amortization period spreads the ECAM recovery over a longer period of time.
The Company is owed this money and it appears as an account receivable on
year-end financial statements. A 12 month amortization period, commencing on
January 1, 2007, would recover these energy charges from customers faster and
the Company is owed less money at year end. The following table shows the
comparison.
Table 8

[45] Thus, an additional
$2,526,419 would be collected from customers with the 12 month amortization
period. The impact to customer monthly billing for the average
residential customer using 650kWh of electricity monthly is shown on Table 9.

[46] The Commission finds
that a 12-month amortization period better represents the true cost to the
consumer. The Commission will order an amendment to the ECAM to reflect
the implementation of 12-month amortization period effective in January, 2007.
