NOTICE
OF RULEMAKING
WELCH,
Chairman; DIAMOND and NUGENT, Commissioners
In this Order we open Docket No.
2002-473, to revise Chapter 380 of the Maine Public Utilities Commission’s
(Commission’s) Rules. The revisions
will implement portions of the requirements of the Conservation Act, enacted by
the Maine Legislature as P.L. 2002, ch. 624.
Current Chapter 380 (Chapter 380-O)
of the Commission’s Rules was promulgated in response to An Act to Secure
Environmental and Economic Benefits, enacted as P.L. 1999, ch. 336. This Act amended 35-A M.R.S.A. § 3211 and
authorized the State Planning Office (SPO) to coordinate the development of a
state energy policy and guide the development of statewide conservation
programs to be implemented by transmission and distribution (T&D) utilities. The SPO’s duties included creating overall
objectives and strategies, reviewing and approving utility implementation
plans, and monitoring and evaluating T&D utility programs. The amended section 3211 required the
Commission to establish total conservation program expenditures for each
T&D utility and to assess T&D utilities to fund the efforts of the
SPO. We adopted existing Chapter 380 to
implement the provisions of section 3211.
During the second session of the 120th
Legislature, the Legislature passed An Act to Strengthen Energy Conservation
(the Conservation Act, or the Act)[1]
that became P.L. 2001, ch. 624, when the Governor signed the Act on April 5,
2002. The Conservation Act repeals
section 3211 and replaces it with section 3211-A, which establishes new terms
that govern an electric energy conservation program in Maine. The Act directs the Commission to develop
and implement electric energy conservation programs that are consistent with
the goals and objectives of an overall energy conservation program strategy
that the Commission must establish. The
programs must be cost effective, according to a definition that the Commission
also must establish.
We open this rulemaking to amend
Chapter 380 to reflect the Conservation Act’s repeal of section 3211 and
enactment of section 3211-A. In the
proposed Chapter 380, we define “low-income residential consumers and” small
business consumers” and establish the test for cost effectiveness, as
specifically directed in the Conservation Act.
In addition, we include certain terms of the Act that will allow Chapter
380 to be a comprehensive compendium of the most significant requirements of
the statewide electric conservation program
In anticipation of this rulemaking,
we opened an Inquiry, Docket No. 2002-272, to
receive comments and suggestions on the definitions of “low income residential
consumers” and “small business consumers.”
We have used the comments we received to develop this draft rule. In the body of this Notice, we will discuss
many of those comments.
In Docket No. 2002-161, we proposed and decided to implement interim
conservation programs. As part of that
process, we established a cost effectiveness test for interim programs, after
proposing a test and receiving comments from interested persons. We also will discuss relevant comments on
cost effectiveness in the body of this Notice.
A. Section
1: Purpose
Section 1 establishes that the purpose of
Chapter 380 is to implement portions of the Conservation Act.
B. Section 2: Definitions
Section 2 contains the definitions
of terms used in the proposed rule.
Many of the definitions are derived directly from 35-A M.R.S.A. §
3211-A. The only terms over which the
Commission may exercise any degree of discretion are “low-income residential
consumers” and “small business consumers.”
Each of these groups must be the target of at least 20% of the
conservation program funding developed and implemented by the Commission.
Subsection D defines “low-income
residential consumer.” In our Inquiry,
Docket No. 2002-272, every commenter but one suggested that we adopt the
criteria for receiving benefits under the Low Income Home Energy Assistance
Program (LIHEAP) as the definition for low-income consumers within this
Chapter. Generally, these commenters
assert that adoption of the LIHEAP criteria will ease the administrative burden
associated with low-income programs because community action agencies (CAPs)
already take applications and certify eligibility based upon consistent
statewide criteria. The criteria are
established annually through a planning and rulemaking procedure carried out by
the Maine State Housing Authority (MSHA), which receives input from a wide
range of low-income stakeholders. In
addition, the criteria – or, more specifically, acceptance for LIHEAP
assistance – are used for a variety of low-income assistance programs such as
Telephone Lifeline and Linkup programs and the utilities’ Electric Low-income
Program (ELP). Commenters assert that
this uniform approach will reduce confusion and is consistent with other
utility-sponsored electric programs.
SESCO, Inc. submitted the only
comments advocating a different definition for low-income consumers. According to SESCO, the LIHEAP criteria will
restrict the group of customers for whom these special conservation programs
should be implemented. Because
LIHEAP-qualified customers already have other energy efficiency programs
available to them, SESCO asserts that using the same eligibility for
Commission-sponsored programs unfairly duplicates the effects of the existing
programs. SESCO urges a wider
definition, so that a larger number of customers would be eligible. Specifically, SESCO supports definitions
that include:
1) a
wider group of assistance recipients, including LIHEAP, TANF, food stamps, and
housing subsidies;
2) residents
in neighborhoods representing the poorest 20% of the state by per capita
income; or
3) households
at a greater percentage of federal poverty guidelines, in order to include
“working poor” families – suggested at or below 250% of federal poverty
guidelines, with renters and senior citizens qualifying at up to 300%.
The proposed rule defines
“low-income consumer” using the LIHEAP criteria. We are persuaded that consistency with existing State programs
will produce significant administrative savings and will eliminate potential
confusion by those who are administering or benefiting from the program.
Further, we expect our program designs to complement, rather than compete with,
current programs such as LIHEAP and therefore do not see any conflict with
these programs. In addition, SESCO’s
suggestion concerning qualification by neighborhood location rather than income
level raises equity concerns. Neighborhoods in Maine, particularly in some of
our rural communities, can have families with widely varying incomes residing
side-by-side, creating the potential for misapplication of limited program
funds.
Our proposed rule does not require a
consumer to carry out the procedures to become certified for LIHEAP benefits to
be considered a low-income consumer.
The proposed rule simply states that the statewide criteria apply
consistently to this rule. As a
practical matter, our program designs may require that a consumer be certified
as eligible before he or she may receive the benefits of a conservation
program.
Subsection H defines “small business
consumer.” Suggestions for the
definition generally fell into two approaches.
The first approach focused on the number of employees and the revenue
generated, which are criteria used to access other governmental programs,
notably those administered by the Finance Authority of Maine (FAME) and the
Department of Economic and Community Development (DECD). FAME and DECD target businesses with fewer
than 50 employees or less than $5 million in revenues, while the Small Business
Development Center suggests targeting businesses with fewer than 100 employees
for its programs. We understand that
98% of Maine businesses have fewer than 100 employees, while 96% of Maine
businesses employ fewer than 50 employees.
The
second approach focused on electricity usage, in particular T&D utility
rate classifications. Each
investor-owned T&D utility contains a rate classification for business
customers with maximum monthly kW load below a particular level.[2] Some commenters asserted that this
breakpoint is convenient and verifiable because a customer’s electric delivery
bill contains the customer’s rate class.
Using the utility rate class breakpoint is consistent with activities
delivered by T&D utilities.
In
establishing a definition of small business consumer, we considered two
principles. First, we intend to choose
a definition that will cause the statutory 20% targeted funding to reach
customers who traditionally have not benefited from conservation programs.[3] Second, we intend to coordinate our
conservation efforts with other State initiatives that assist small business
consumers.
With
this in mind, the proposed rule defines a small business consumer to be a
business with fewer than 50 employees.
This definition is consistent with that used by the State’s business
development community, allowing our programs to complement the economic
development and loan programs offered by other State government entities. We chose 50 (rather than 100) employees
because this definition is consistent with criteria used by more State
organizations that we are certain to interact with as we implement our
programs. We reject a suggested
definition of 20 or fewer employees, because these levels could exclude some
small businesses that have been underserved by previous programs. We do not propose to include company
revenue as part of our definition, despite its inclusion in many agencies’ criteria,
because a revenue criterion would be complex to determine and confirm for the
hundreds of customers who will participate in our programs.
Utility
rate class definitions are convenient when utilities are implementing the
programs, but are less convenient when that is no longer the case. Further, utility rate class definitions are
not consistent across the state, which could further complicate program
marketing and implementation. We also
reject utility rate class definitions because electricity use may be a poor
indicator for the customers that the Act intended to assist through its 20%
target requirement. There may be
customers with electricity-intensive business processes who have limited staff
to address issues of energy efficiency.
It is arguably more important to provide assistance to these customers
than to customers with lower electricity use.
A definition that depends on employment level will allow such a customer
to benefit from programs targeted to small businesses.
The
definition clarifies the treatment of part-time employees and seasonal
businesses. In addition, it states
that, if a company has businesses in multiple locations, the number of
employees in all locations shall be combined when determining the number of
employees to be used under this definition.
This provision excludes some smaller locations that are owned by larger
chains, thereby limiting small business assistance to businesses that do not
have access to the energy expertise that may be present through ownership by a
regional or national organization.
However, this treatment of businesses with multiple locations may be
inconsistent with their treatment by other agencies dealing with small
businesses. We invite commenters
familiar with small business operations to comment on all portions of this
definition.
C. Section 3: Conservation Programs
Section 3 of the proposed rule
incorporates the terms in the Conservation Act that require the Commission to
establish goals for the conservation programs.
We include a substantial portion of the Act so that Chapter 380 will be
a comprehensive compendium of the basic State conservation program
requirements.
Subsection A of section 3 restates the criteria, in the form of high
level goals, that the Commission must consider in selecting its portfolio of
programs.
Subsection B states that the Commission shall establish goals,
objectives, and strategies that will govern selection of conservation
programs. We began that process when we
issued our Proposed Order Establishing Goals, Objectives and Strategies for
Conservation Programs on August 6, 2002, in Docket No. 2002-162. In that Proposed Order, we stated that the
Act directs the Commission to develop an “overall energy strategy.” We further stated that, in our view, it is
not appropriate or reasonable for the Commission to develop a statewide energy
policy that encompasses all fuels, nor is it necessary for successful
implementation of the Act. It is more
appropriate that we develop a group of goals, objectives, and strategies that
will govern an electricity conservation program portfolio in a comprehensive
manner. Subsection B reflects this
approach, by requiring us to determine goals, objectives, and strategies for
the statewide program.
Subsection B also establishes the immediate and longer-term processes
the Commission will follow to establish and revise goals, objectives, and
strategies for conservation programs.
The Act directs us to determine a schedule to revise our objectives and
overall energy strategy. Subsection B
guarantees that a revision process will occur no less frequently than every two
years.
Subsection C summarizes the requirements in the Act that the statewide
portfolio of conservation programs must be cost effective, must attain the
goals, objectives, and strategies determined by the Commission and must be
delivered without exceeding the assessed funds.
D. Section 4: Cost Effectiveness Criteria
In Docket No. 2002-161, we presented
background and options for determining the cost effectiveness of interim
programs.[4] We encourage interested persons to read the
discussions in the Order in that proceeding and in the concurring opinion, and
we have included those sections of the document in Appendices A and B. In that proceeding, we decided to rely on
the framework established in Ch. 380-O to determine the cost effectiveness of
individual interim programs and of the portfolio of programs. Under that framework, we rely on the All
Ratepayers Test to screen for cost effectiveness, but we also consider whether
a program or group of programs is likely to have a significant impact on
T&D utility rates.
Historically, the Commission has
considered three cost effectiveness tests.
The primary test has been the All Ratepayers Test (ART), which measures
whether a conservation program provides the same level of end use amenity (e.g.
lighting or hot water) at a lower overall net cost to utilities and ratepayers
taken together. The second test has
been the Rate Impact Test, which measures the impact of a program on the
average electric utility rate. Finally,
the Societal Test is an expansion of the ART, in that it includes environmental
and other social benefits external to the transaction between the utilities and
their customers.
Most other states – and
particularly Northeast states -- use variations of the ART, variously called
Total Resource Cost Test, Modified Total Resource Cost Test, Societal Test, or
Modified Societal Test. These tests are
distinguished by the fact that they include costs or benefits associated with
non-electric resources (e.g., increased use of gas or water), customer O&M
expenses (e.g., reduced maintenance on a more efficient product), and improved
ability to pay electric bills. They may
include “spillover effects” (e.g., adoption of additional efficiency measures
by customers outside of the efficiency program). Societal Tests may include
costs and benefits accruing outside of Maine, such as environmental
effects. Finally, some states attempt
to include economic development and job creation benefits. On the other hand, some states consider cost
effectiveness from the participant’s perspective or from the utility’s
perspective.
Quantification of some of these
costs and benefits is problematic. Some
states solve this problem by creating a percentage adder to represent
environmental or other non-quantifiable costs.
In general, these adders are not meant to represent a measured level of
benefit, but are meant to acknowledge that some benefit exists and should be
recognized.
Appendix C contains a summary of
the most common costs and benefits included in commonly considered cost
effectiveness tests. Appendix D
contains a summary of our understanding of other states’ cost effectiveness tests.
In subsection A of section 4, we
define a Modified Societal Test[5]
as the cost effectiveness test that will be used for permanent (as opposed to
interim) conservation programs. We
intend to consider as many costs and benefits as are reasonably quantifiable,
regardless of who pays or experiences the cost or benefit. This approach is consistent with the All
Ratepayer Test approach taken in years past, but expands the approach to
include factors that clearly result from the programs. We recognize that some factors will continue
to be difficult to quantify. We do not
propose creating a percentage adder to represent those factors. Rather, we intend to quantify when possible
and simply report program effects when quantification is not possible.
Subsection 1 lists benefits to be included in the cost
effectiveness calculation. Avoided
electric generation costs will be estimated using regional prices. The proposed
rule states that an average generation cost is adequate, but that more precise
estimates based on time differentiation may be used when appropriate. Avoided T&D costs will rely on T&D
utilities’ marginal cost estimates, which also may be averages or time
differentiated estimates. Utilities have
commented that their marginal cost estimates are imprecise. However, they are clearly the most
appropriate quantities available.
Avoided fuel savings will include reduced use of oil, gas, or any other
fuels saved. The proposed rule does not
specify a method for calculating fuel savings – we will use the best estimate
available. Similarly, avoided costs of
water, sewer, or any other resource will be estimated as accurately as is
possible and reasonable. Finally,
subsection (e) establishes that any other benefit that we can reasonably
quantify will be included in the cost effectiveness test. We conclude that these benefits are
important outcomes of conservation programs – sometimes by design and sometimes
by good fortune – and they should be acknowledged whenever possible.
Subsection 2 lists costs to be
included in the cost effectiveness calculation. Direct program costs listed in subsection (a) and capital costs
associated with the purchase and installation of appliances or equipment,
listed in subsection (b), are traditional costs included in cost effectiveness
tests. Subsection (c) lists other costs
such as increased customer operation and maintenance costs. Considering such costs is consistent with
considering all benefits that can be recognized as resulting from a program.
Subsection 3 establishes
guidelines for the discount rate to be used in cost effectiveness
calculations. The cost effectiveness of
a program is calculated from the perspective of Maine consumers as a whole (as
opposed to only the participant). Thus,
the discount rate should be a societal discount rate. Long-term treasury securities yields are reasonable for this
purpose.
Subsection 4 establishes that
costs and benefits will all be measured on a comparable, net present value,
basis. This is a traditional,
established calculation method.
Consistent with our intent to
consider all costs and benefits that can be recognized, subsection 5
establishes that costs and benefits will be estimated for as many years in the
future as seems reasonable.
Subsection B of section 4
accommodates programs that satisfy statutory or Commission-established goals
but whose benefits cannot be quantified.
While we will measure costs and benefits whenever possible, we conclude
that there are programs that will benefit consumers in Maine, or that meet
statutory criteria, but whose benefits cannot be reliably estimated. Indeed, there may be requirements of the Act
that cannot be met if all programs must pass the Modified Societal Test. In particular, it may be impossible to spend
20% of total funds on low-income or small business programs and it may be
impossible to conduct energy education as the Act contemplates, unless programs
with non-quantifiable benefits are considered.
The subsection includes three criteria, all of which must be met, before
a program can be implemented without passing the Modified Societal cost
effectiveness test. Subsection 4(B)(1)
allows a program with non-quantifiable benefits to be implemented, while
subsection 4(B)(2) establishes that the program must meet statutory or
Commission-established goals and subsection 4(B)(3) establishes that the entire
portfolio must be substantially cost effective.
This subsection creates the
possibility that a program whose benefit-to-cost ratio is quantifiable
but is less than one, and that meets particular goals, cannot be
implemented. However, a program whose
benefit-to-cost ratio is not quantifiable, and meets the same goals, may
be implemented. We invite comments on
these possibilities as well as on all potential outcomes of this subsection.
In addition to commenting on any
aspect of our proposed cost effectiveness tests, we invite interested persons
to express their views on whether there should be a quantitative standard for
the distribution of benefits. To
elaborate, the proposed test looks at benefits and costs in the aggregate. Should the Commission also be required to
find that benefits will exceed costs for some minimum percentage of Maine
consumers? For example, if it were determined
that for a particular portfolio of programs the benefits will exceed the costs
in the aggregate (i.e., the portfolio passes the Modified Societal Test) but
that only 20% of consumers will actually receive more in benefits than they pay
in costs, should that portfolio be deemed cost effective?
We also welcome comments on whether
the existence of statutory requirements that certain percentages of the
spending be directed at specified groups and that all groups be given the
opportunity to participate warrants the conclusion that the Legislature did not
expect the Commission to deal further with distributional equity issues. Even if one answers this question in the
negative, is it realistic to expect the Commission to be able to determine the
percentage of ratepayers who will have a benefit-to-cost ratio in excess of 1
for a particular program or portfolio of programs? Finally, given the Commission’s conclusion that the Rate Impact
Test is not feasible in a restructured environment, which means that some and
perhaps many ratepayers may have costs in excess of benefits from these programs,
should the Commission suggest to the Legislature that it may want to reexamine
the statute?[6]
E. Section
5: Funding Level
Section 5 of the
proposed rule restates the terms in the Conservation Act that establish a
funding mechanism for the conservation programs. We include this restatement of law so that Chapter 380 will be a
comprehensive compendium of the basic State conservation program
requirements. Subsection A directly
quotes the Act, and describes the upper and lower bounds of the amounts the
Commission will assess T&D utilities to fund the programs. Subsections C and D directly quote the Act,
and describe the means by which the Commission will categorize the budget and
spending of the funds assessed.
Subsection B is not contained in the Act. It establishes broad guidelines for determining the dollar amount
that we will assess as time goes by. It
states that the Commission’s periodic assessment will be based on projections
of the factors[7] that
determine the assessment, but that reconciliation will occur to ensure that the
assessment over time comports with the actual values of those factors.
F. Section
6: Waiver or Exemption
Section 6 contains terms
governing waiver or exemption from the Chapter. These terms are standardized throughout the Commissions rules.

Appendix A
Selected Text
from the Commission’s June 13, 2002 Order Establishing Interim Conservation
Programs
The
Conservation Act requires that the Commission only implement interim programs
that it finds cost effective.[8] In implementing section 7 of the Act, we
seek to answer three broad questions: (1) how will we evaluate the cost
effectiveness of specific interim programs, (2) to what extent should we
consider the provisions of newly-enacted 35-A M.R.S.A. § 3211-A (section 4 of
the Act) when approving interim programs, and 3) are there other criteria to
consider?
A. Cost
Effectiveness
1. Appropriate
tests
Cost effectiveness testing for conservation
programs has a long history before this Commission. For example, the Electric Rate Reform Act stated 25 years ago
that
The Commission,
as it determines appropriate, shall order electric public utilities to submit
specific rate design proposals and related programs for implementing energy
conservation techniques and innovations … Such proposals shall, as the
Commission determines, be designed to encourage energy conservation, minimize
the need for new electrical generating capacity, and minimize the costs of
electricity to consumers… (Public Laws, 1977, Chapter 521).
Thus, we have spent the last twenty-five
years considering, and periodically reconsidering, how to test whether proposed
conservation measures are likely to minimize electricity (and sometimes other)
costs. The debate typically is framed
in terms of which of various cost effectiveness tests should be applied. That debate is generally reducible to a
debate over our goals in adopting conservation programs.
Our
last thorough review of this question was in 1988, when we adopted amendments
to Chapter 380, Demand Side Energy Management Programs by Electric Utilities,
(Docket No. 88-178).[9] When considering the cost effectiveness of
interim conservation programs, we propose to use the cost effectiveness
framework established in the original Chapter 380 (Ch. 380-O).
Ch.
380-O defined three cost effectiveness tests, but principally relied upon the
“All Ratepayers Test.” This test
measures whether a proposed conservation program provides the same level of end
use amenity (e.g. lighting or hot water) at a lower overall net cost to
utilities and ratepayers taken together.
The
second cost effectiveness test in Ch. 380-O was the “Rate Impact Test.” This test measures the impact of a
conservation program on the overall average rate of the electric utility (in $
per kWh) rather than the total dollar cost.
This is a stricter test than the All Ratepayers Test. A decline in electricity use, from a
conservation program or for some other purpose, will tend to reduce the
utility’s profit, to the extent the reduction in revenue from lower sales is
greater than the utility’s savings from lower sales. At the present time, with utilities limited to the transmission
and distribution (T&D) business and continuing to carry substantial
stranded costs in their rates, it is unlikely that many conservation programs
will pass the Rate Impact Test.[10]
The
third cost effectiveness test in Ch. 380-O was the Societal Test, which
included all elements of the All Ratepayers Test as well as “environmental
benefits and any other social benefits external to the transaction between the
utilities and its customers.”
Ch.
380-O provided for automatic approval of any programs that passed both the All
Ratepayers Test and the Rate Impact Test and for programs that passed the All
Ratepayers Test and did not have a significant (defined as one percent) impact
on the average rate per kWh. There was
no indication in Ch. 380-O of how, if at all, the Societal Test should be
employed in analyzing conservation programs.
For purposes of determining the cost
effectiveness of interim conservation programs, we will utilize the framework
established in Ch. 380-O. We will rely
primarily on the All Ratepayers Test to screen for cost effectiveness but will
also consider whether conservation programs, or groups of programs, are likely
to have a significant impact on rates.[11] In addition, just as Ch. 380-O provided the
Commission with flexibility to approve programs that did not meet these
thresholds, we will not automatically reject programs that fail to meet either
or both of these tests if there is sufficient evidence that the programs are
likely to prove cost effective by some other reasonable measure. For example, we might approve an interim
program that targets specific ratepayer populations or a pilot program that
aids in gathering information to develop future conservation programs or lays a
foundation that promises to enhance program effectiveness over time.
2. Comments
on the Proposed Order
Two parties, CMP and the Residential/Small
Commercial Service Providers Coalition (the Coalition), provided comments that
were almost diametrically opposed. CMP
argued that we should rely upon the Rate Impact Test on the grounds that
conservation funding was being recovered through a surcharge on electric rates. The Coalition argued that we should retain
the All Ratepayers Test but consider the avoided cost to be the avoided cost to
the individual ratepayer (i.e., the electricity rate) rather than avoided (or
marginal) costs of generating and consuming less electricity.
We believe that the most appropriate approach
to cost benefit determinations is to consider whether the total cost to society
would be lower if a particular conservation action is taken. Adopting CMP’s suggestion of the Rate Impact
Test would result in our rejecting conservation measures which produce a net
decrease in total costs. Thus, we will
not accept CMP’s suggested use of the Rate Impact Test. Similarly, we will reject the Coalition
suggestion to use retail rates as avoided costs. The Coalition recommendation could, and probably would, have us
approving conservation programs which raise overall costs. This would occur whenever the savings to an
individual ratepayer would come only at the expense of imposing additional
costs on other ratepayers which exceeded the savings to the participants.
Another, perhaps simpler, way of stating
this issue is to compare two hypothetical cases. Each case focuses on a conservation measure which results in
lower costs to the participant in the conservation program. In the first, the participant saves $100
while other ratepayers incur a cost of $50.
CMP would have us reject this program because the $50 loss would violate
the Rate Impact Test. In the second
case, the $100 savings yields a $150 loss to other ratepayers. The Coalition would have us approve the
program because the participant would save $100. Under the All Ratepayers Test, we would approve the first
program, since the gain to the participant is greater than the loss to others,
but we would reject the second program since it would result in a net
loss. We believe this to be the right
outcome and will rely primarily on the All Ratepayers Test.
In addition, Glenn Reed of NEEP offered two
recommendations regarding cost effectiveness.
First, Mr. Reed suggested that we analyze cost effectiveness on a
multi-year basis to reflect the fact that a program may be beneficial over its
entire lifetime even if it were not cost effective in one or more individual
years. Here, we agree with Mr. Reed in
concept, but note that all of the cost effectiveness tests should take a
multiyear perspective while discounting future benefits relative to immediate
benefits. This is, and has been, a
common practice. Mr. Reed also suggests
that we include non-electric benefits (e.g., savings of other operating costs)
as well as program impacts which occur outside the program itself (e.g., post
program adoption of efficiency measures).
Here too, we agree in principle, but with the observation that such
effects may be difficult to estimate reliably.
Finally, Competitive Energy Services (CES)
is concerned that we should be certain that our cost benefit tests fully
capture the effects of conservation measures on our estimates of the likely
price of electric energy. Specifically,
CES states: “We know that demand-side response has a very powerful effect on
the establishment of market clearing prices in NEPOOL which then reduce the
cost of electricity to all other ratepayers in the market. This benefit of DSM appears to be missing
from the calculation methodology proposed by the Commission”.
While the concern raised by CES is
theoretically correct, it is unlikely to have any significant effect on the
analysis of any individual interim DSM program. In most, if not all, cases, the interim programs we will consider
are too small to exert a significant impact on the energy market and a method
for estimating such an effect requires development. That said, we would not rule out considering such secondary
impacts where there is credible evidence that those impacts are significant and
could be reasonably estimated.
3. Calculation of Costs and Savings
Beyond the specific choice of which cost
effectiveness tests to use, there are also data issues. While program costs and energy savings can
be considered on a case-by-case basis, certain principles apply to all
programs.
First, we establish methods for converting
energy savings into dollar cost savings.
Ch. 380-O relied on estimations of avoided costs. While prior to restructuring the Commission
periodically approved avoided costs for each of the large electric utilities,
we no longer do so. When considering
interim conservation programs, we will determine generation cost savings by
looking to the competitive generation market.
For residential and small commercial and industrial (C&I) customers,
we will use the prices under existing standard offer contracts for the
remaining term of those contracts, since most residential and small C&I
customers take service under the standard offer. For other customers, we will base estimates of cost savings on
current market conditions as reported in the trade press (e.g. the Natsource
quotes of electricity prices for futures contracts). Where the futures market is thinly traded, we will rely on the
next best available sources[12].
L. K. Goldfarb Associates suggested using
long-term avoided costs recently developed and approved in Massachusetts. CMP proposed using the T&D utilities’
entitlement sales prices as estimates of avoided generation cost. MPS and BHE commented that standard offer
prices reflect shorter term, rather than long-term, avoided costs. We will consider these viewpoints when we
determine cost effectiveness analysis for long-term programs in Docket No.
2002-162. We believe the simpler
approach we have accepted in this Order is adequate for judging interim
programs in the short time frame in which we are operating.
We propose to base delivery cost savings
(i.e., the costs saved for transmission and distribution) on the marginal
T&D costs used to evaluate special rate contracts under utilities’ pricing
flexibility programs. The Commission
routinely approves marginal costs for some utilities. We plan to use reasonable estimates of marginal costs for
utilities that have not filed marginal costs in recent years.
CMP commented that its marginal cost
calculations are not particularly reliable.
However, these values are quite small and will serve to represent that
there is some cost, although small, associated with T&D delivery. We also note that CMP has endorsed use of
these estimates for other purposes.
Finally, many states currently use
cost effectiveness tests that include costs or benefits associated with
non-electric resources (e.g., increased use of gas or water), customer O&M
expenses (e.g., reduced maintenance on a more efficient product), post-program
adoption (e.g., the removal of an efficiency measure), and so-called “spillover
effects” (e.g., adoption of additional efficiency measures in response to
customers’ satisfaction with the original measure). Many commenters supported including such costs and benefits, but
only if they can be reliably calculated.
We agree. The All Ratepayers
Test does not preclude considering such costs and benefits, and we will do so
to the extent they can be reasonably well quantified and are reasonably certain
to occur.
4. Ability
to Calculate Cost Effectiveness
Conservation programs may be divided broadly
into two categories, which we will call primary-effect programs and
secondary-effect programs.
Primary-effect programs are those in which program funding is directly
related to kWhs saved. For example, a
program that pays a customer a fixed rebate to replace an existing motor with a
more efficient motor is a primary-effect program. Program planners can be reasonably certain that some level of
savings will occur and can either directly measure the savings or can make a
reasonable calculation of savings based on engineering estimates.
Secondary-effect programs are those in which
funding is paid to an intermediary, who in turn uses the money for one of a
variety of purposes aimed at influencing an energy consumer’s behavior. For example, an education or advertising
program funds an entity that then influences consumers to use less energy or
use it more efficiently. In this
instance, cost effectiveness is more difficult to measure, since there is no
direct link allowing program planners to measure behavior that results from the
program.
While we recognize that both types of
programs have advantages and disadvantages, we will strongly favor
primary-effect programs in the interim period.[13] Secondary-effect programs necessarily
require more investigation before we can ascertain effectiveness and therefore
we are less likely to be able to evaluate their cost effectiveness sufficiently
to implement them on an interim basis this summer. Most commenters agreed with our preference, with some commenters
asserting that only primary-effect programs should be operated in the interim
period. While favoring primary-effect
programs, we will not foreclose the possibility of offering secondary-effect
programs, because some education and training programs appear to pose clear
benefits to consumers.
Appendix B
Separate Opinion
of Commissioner Diamond
from the Commission’s June 13, 2002 Order Establishing
Interim Conservation Programs
I
concur with the decision of the Commission on the cost effectiveness test for
interim conservation programs and on the specific programs to be adopted. In doing so, I am motivated in part by the
need to implement at least some programs without further delay and by the
Commission’s past reliance on the All Ratepayers Test. I have sufficient doubts about that test,
however, that I believe it warrants further scrutiny when we consider permanent
conservation programs, a process for which we will fortunately have more time.[14] Thus, the purpose of this separate opinion
is to raise certain cost effectiveness issues that I hope will be more
completely addressed in the context of the permanent programs.
Before discussing the All Ratepayers Test, let me offer
some brief observations about the two alternatives - the Rate Impact Test and
the Societal Test. Both have perfectly
reasonable goals, but as discussed in the Commission’s Order, have defects in
serving as measurement tools, especially for specific programs.
Projects
that pass the Rate Impact Test are easy to justify in theory. If the savings of the non-participant for
the same amount of electric consumption are greater than the amount of the
conservation assessment, everybody wins, with the possible exception of the
shareholders of utilities under long-term incentive rate plans. Unfortunately, with a competitive wholesale
electricity market that operates on a regional basis, we may never be able to
conclude with any confidence that a particular conservation program or
portfolio of programs reduces the price of power by a material amount, thereby
calling into question the future relevance of this test.[15] In addition, use of this test would militate
in favor of concentrating on peak shaving programs, as that is where there
would be the greatest potential to reduce energy prices.
I also support the theoretical underpinnings of the
Societal Test, since benefits such as a cleaner environment and a stronger economy
inure to all. Again, my problem is
whether anyone can demonstrate a sufficient nexus between traditional
conservation programs and these benefits to satisfy a cost effectiveness test. For example, there may well be more direct
ways to improve the environment than through programs that do not differentiate
between electricity generated by wind and by coal. If environmental protection is indeed one’s goal, would we not
get more bang for the buck by spending to promote green power than by spending
to curtail usage regardless of the generation source? In short, the broader goals envisioned by the Societal Test
require a far more expansive consideration of the alternatives, including those
that do not involve conserving electricity.
Given the great difficultly, if not the impossibility, of
measuring benefits under the tests described above, the decision to rely on the
All Ratepayers Test is not surprising.
Under that approach, we treat all consumers as if they are a single
consumer by measuring whether, as a group, their savings in electricity costs
under a particular program are greater than the cost to them of that program.
As I understand it, the benefit from satisfying the All
Ratepayers Test is that as a society we spend less for electricity, through
greater efficiency rather than through diminished output, and thus have more to
spend on other goods and services. By
itself, that certainly is a laudable goal.
The problem arises, however, from the fact that especially in limited
participant programs,[16]
the costs are borne by the many and the benefits go to the few, and it falls to
government to effect this transfer in wealth.
And if the object is to maximize the amount of electricity saved, the
argument can be made that the winners should be those who use the most
electricity in the most inefficient manner, as they have the potential to
achieve the greatest savings.
My doubts about the wisdom of using this collective
approach to measuring costs and benefits to justify having government transfer
wealth stem in part from the following question: if this is such a good idea,
why do we not do it in other areas? Why
do we not impose an assessment on heating oil purchases and operate heating oil
conservation programs whenever we can demonstrate that the collectively
measured gains will be greater than the collectively measured costs? Why do we not impose an assessment on car
purchases and give stipends to some customers to purchase hybrid cars if the
aggregate savings in gasoline will be greater that the total amount of the
assessments? These programs arguably
have the added advantage of promoting national security.
Indeed, we could have this type of program for any
commodity for which bulk purchases are available. As a group, we might be able to buy oranges more cheaply with a
modest assessment on all given to some to buy in bulk. By spending less as a society on Vitamin C,
we could spend more on Vitamin A.
My uneasiness is only enhanced by the fact that the
transfer of wealth accompanying this collectivization of costs and benefits is
carried out not by the market but by government. It was hardly surprising that we received an unusually large
number of comment letters in this Docket and that the vast majority support
conservation. As with any endeavor
where the benefits to a few may be substantial[17]
and the cost to the many modest, those whose only involvement may be to pay the
assessment are too busy making a living and raising a family to intervene in
Commission proceedings.
In fairness, certain conservation programs involve a
minimal or no transfer of wealth and are thus easy to justify. For example, improving the efficiency of
government buildings potentially benefits all taxpayers, and thus, the same
people pay for and benefit from the project.[18] In programs designed for low-income electric
consumers, the transfer of wealth may itself be a valid objective, and in light
of Maine’s statewide assistance program, reducing consumption by this group may
actually result in savings for all ratepayers.
One way of addressing the distributional equity issue is
by requiring, as the Conservation Act endeavors to do, that the benefits be
spread among the different classes of ratepayers. While this may limit the problem, it does not eliminate the question
of whether and under what circumstances this transfer of wealth is justified,
especially if one is unable to demonstrate that the programs are really the
best way to achieve other social goals.
Before we spend other people’s money, we have an obligation to fully
answer that question, and I look forward to doing so when we consider the
permanent conservation programs.[19]

Some commenters suggested that, if we
target 20% of available funding to small business customers and 20% to
low-income customers, then all remaining funds will be targeted to “non-small”
business customers and “non-low-income” residential customers, resulting in a
proportionally low level of funding for small business customers. We disagree. The Act does not preclude us from applying a portion of the
remaining 60% of funds to small business consumers.

Proposed Order Establishing Goals and Criteria for Interim Conservation Programs,

Interim Conservation Programs issued June 13, 2002 contain extensive discussion
of cost effectiveness tests. Both

Comments from interested persons are available on the Commission’s
Virtual Docket, also available on our web page.
[5] This test
could legitimately have been called a Modified Total Resource Cost Test.
[6] This does
not necessarily mean abandoning the concept of imposing an assessment on
ratepayers for the purpose of achieving societal goals related to the use of
electricity. To the contrary, a
relevant question is whether there are more effective ways to achieve the
objectives usually associated with conservation programs. For example, for purposes of protecting the
environment, might it be more effective to use some of the assessment to
promote green power or to force changes in environmentally unfriendly
generation facilities rather than rely entirely on the proposition that using
electricity more efficiently is generally good for the environment?
[7] Pursuant
to the Act, assessments must be capped at 1.5 mils per kWh, but must be no less
than 0.5% of revenues. Currently, we
assess CMP based on its kWh sales, and we assess all other utilities based on
revenues. We will determine the basis –
whether sales, revenues, or some other factor – and the level for long-term assessments
in future proceedings.
[8] A program
cannot definitively be found cost effective until after it has been in
operation for some period of time and an evaluation has been performed. We interpret the Act’s requirement to
require that we determine that an interim program is highly likely to be cost
effective.
[9] This
version of the rule was replaced in 1999 with a new version reflecting the
provisions of 35-A MRSA §3211, which assigned many of the responsibilities for
conservation programs to the State Planning Office. The Conservation Act repeals §3211 and returns responsibility for
conservation programs to the Commission.
[10] The
exception here may be conservation programs which are primarily focused on use
during on-peak periods.
[11] Under
alternative rate plans, some utilities’ rates would not be affected
immediately, if at all.
[12] For
example, the US Department of Energy routinely publishes forecasted energy
prices. See
http://www.eia.doe.gov/oiaf/aeo/index.html.
[13] However,
primary-effect and secondary-effect programs exhibit competing advantages. While secondary-effect benefits are more
difficult to measure, secondary-effect programs may have the advantage of
benefiting a larger number of consumers.
[14] While the
Order observes that the Commission has been struggling for 25 years with the
question of how to measure the cost effectiveness of conservation programs,
this is the first time it has received in-depth consideration during my tenure.
[15] How to
measure the impact of conservation programs on the price paid for electricity
by non-participants may warrant further consideration when we address permanent
programs.
[16] My doubts about the All Ratepayers Test are
strongest in the context of limited participant programs, as the savings are
enjoyed by only a few consumers while the majority pays more. Unfortunately, these are often the primary
effect programs, in which the savings are easiest to measure. As a result, achieving certainty of savings
and a broad distribution of benefits may at times be conflicting goals.
[17] The
possibility that some of these programs might someday be seen as boondoggles is
enhanced by the fact that the All Ratepayers Test only allows projects with
savings greater than costs. Thus, we
are transferring wealth to subsidize measures which, even without the subsidy,
would benefit the participants.
[18] To the
extent that a conservation assessment is a more regressive way to raise money
than the income tax, there is the question of why we should use the former to
achieve savings in the latter. This
arises because at the State level, the assessment would be used for the
conservation measure while the electricity bill is paid with tax dollars.
[19] It may be
argued that by passing the Conservation Act, the Legislature answered this question. The Act, however, gives the Commission
extremely broad discretion in deciding cost effectiveness and determining the
amount to spend on conservation, and I believe the issues raised in this
opinion should be addressed if we are to carry out those tasks in a thoughtful
manner. Alternatively, we might decide
to raise these issues with the Legislature if we conclude we need clearer
guidance on how it would like us to proceed.
