20 CSR 4240-22.050
Demand-Side Resource Analysis
PURPOSE: This rule specifies the principles
by which potential demand-side resource
options shall be developed and analyzed for
cost effectiveness, with the goal of achieving
all cost-effective demand-side savings. It also
requires the selection of demand-side candidate resource options that are passed on to
integrated resource analysis in 4 CSR 24022.060 and an assessment of their maximum
achievable potentials, technical potentials,
and realistic achievable potentials.
(1) The utility shall identify a set of potential
demand-side resources from which demandside candidate resource options will be identified for the purposes of developing the alternative resource plans required by 4 CSR
240-22.060(3). A potential demand-side
resource consists of a demand-side program
designed to deliver one (1) or more energy
efficiency and energy management measures
or a demand-side rate. The utility shall select
the set of potential demand-side resources
and describe and document its selection—
(A) To provide broad coverage of—
1. Appropriate market segments within
each major class;
2. All significant decision-makers,
including at least those who choose building
design features and thermal integrity levels,
equipment and appliance efficiency levels,
and utilization levels of the energy-using capital stock; and
3. All major end uses, including at least
the end uses which are to be considered in the
utility’s load analysis as listed in 4 CSR 24022.030(4)(A)1.;
(B) To fulfill the goal of achieving all costeffective demand-side savings, the utility
shall design highly effective potential
demand-side programs consistent with subsection (1)(A) that broadly cover the full
spectrum of cost-effective end-use measures
for all customer market segments;
(C) To include demand-side rates for all
customer market segments;
(D) To consider and assess multiple
designs for demand-side programs and
demand-side rates, selecting the optimal
designs for implementation, and modifying
them as necessary to enhance their performance; and
(E) To include the effects of improved
technologies expected over the planning horizon to—
1. Reduce or manage energy use; or
2. Improve the delivery of demand-side
programs or demand-side rates.
(2) The utility shall conduct, describe, and
document market research studies, customer
surveys, pilot demand-side programs, pilot
demand-side rates, test marketing programs,
and other activities as necessary to estimate
the maximum achievable potential, technical
potential, and realistic achievable potential of
potential demand-side resource options for
the utility and to develop the information necessary to design and implement cost-effective
demand-side programs and demand-side
rates. These research activities shall be
designed to provide a solid foundation of
information applicable to the utility about
how and by whom energy-related decisions
are made and about the most appropriate and
cost-effective methods of influencing these
decisions in favor of greater long-run energy
efficiency and energy management impacts.
The utility may compile existing data or
adopt data developed by other entities,
including government agencies and other utilities, as long as the utility verifies the applicability of the adopted data to its service territory. The utility shall provide copies of
completed market research studies, pilot programs, pilot rates, test marketing programs,
and other studies as required by this rule and
descriptions of those studies that are planned
or in progress and the scheduled completion
dates.
(3) The utility shall develop potential
demand-side programs that are designed to
deliver an appropriate selection of end-use
measures to each market segment. The utility shall describe and document its potential
demand-side program planning and design
process which shall include at least the following activities and elements:
(A) Review demand-side programs that
have been implemented by other utilities with
similar characteristics and identify programs
that would be applicable for the utility;
(B) Identify, describe, and document market segments that are numerous and diverse
enough to provide relatively complete coverage of the major classes and decision-makers
identified in subsection (1)(A) and that are
specifically defined to reflect the primary
market imperfections that are common to the
members of the market segment;
(C) Identify a comprehensive list of enduse measures and demand-side programs
considered by the utility and develop menus
of end-use measures for each demand-side
program. The demand-side programs shall be
appropriate to the shared characteristics of
each market segment. The end-use measures
shall reflect technological changes in enduses that may be reasonably anticipated to
occur during the planning horizon;
(D) Assess how advancements in metering
and distribution technologies that may be reasonably anticipated to occur during the planning horizon affect the ability to implement
or deliver potential demand-side programs;
(E) Design a marketing plan and delivery
process to present the menu of end-use measures to the members of each market segment
and to persuade decision-makers to implement as many of these measures as may be
appropriate to their situation. When appropriate, consider multiple approaches such as
rebates, financing, and direct installations for
the same menu of end-use measures;
(F) Evaluate, describe, and document the
feasibility, cost-reduction potential, and
potential benefits of statewide marketing and
outreach programs, joint programs with natural gas utilities, upstream market transformation programs, and other activities. In the
event that statewide marketing and outreach
programs are preferred, the utilities shall
develop joint programs in consultation with
the stakeholder group;
(G) Estimate the characteristics needed for
the twenty (20)-year planning horizon to
assess the cost effectiveness of each potential
demand-side program, including:
1. An assessment of the demand and
energy reduction impacts of each stand-alone
end-use measure contained in each potential
demand-side program;
2. An assessment of how the interactions
between end-use measures, when bundled
with other end-use measures in the potential
demand-side program, would affect the
stand-alone end-use measure impact estimates;
3. An estimate of the incremental and
cumulative number of program participants
and end-use measure installations due to the
potential demand-side program;
4. For each year of the planning horizon, an estimate of the incremental and
cumulative demand reduction and energy savings due to the potential demand-side program; and
5. For each year of the planning horizon, an estimate of the costs, including:
A. The incremental cost of each
stand-alone end-use measure;
B. The cost of incentives paid by the
utility to customers or utility financing to
encourage participation in the potential
demand-side program. The utility shall consider multiple levels of incentives paid by the
utility for each end-use measure within a
potential demand-side program, with corresponding adjustments to the maximum
achievable potential and the realistic achievable potential of that potential demand-side
program;
C. The cost of incentives to customers
to participate in the potential demand-side
program paid by the entities other than the
utility;
D. The cost to the customer and to
the utility of technology to implement a
potential demand–side program;
E. The utility’s cost to administer the
potential demand-side program; and
F. Other costs identified by the utility;
(H) A tabulation of the incremental and
cumulative number of participants, load
impacts, utility costs, and program participant costs in each year of the planning horizon for each potential demand-side program;
and
(I) The utility shall describe and document
how it performed the assessments and developed the estimates pursuant to subsection
(3)(G) and shall provide documentation of its
sources and quality of information.
(4) The utility shall develop potential
demand-side rates designed for each market
segment to reduce the net consumption of
electricity or modify the timing of its use.
The utility shall describe and document its
demand-side rate planning and design process
and shall include at least the following activities and elements:
(A) Review demand-side rates that have
been implemented by other utilities and identify whether similar demand-side rates would
be applicable for the utility taking into
account factors such as similarity in electric
prices and customer makeup;
(B) Identify demand-side rates applicable
to the major classes and decision-makers
identified in subsection (1)(A). When appropriate, consider multiple demand-side rate
designs for the same major classes;
(C) Assess how technological advancements that may be reasonably anticipated to
occur during the planning horizon, including
advanced metering and distribution systems,
affect the ability to implement demand-side
rates;
(D) Estimate the input data and other characteristics needed for the twenty (20)-year
planning horizon to assess the cost effectiveness of each potential demand-side rate,
including:
1. An assessment of the demand and
energy reduction impacts of each potential
demand-side rate;
2. An assessment of how the interactions
between multiple potential demand-side
rates, if offered simultaneously, would affect
the impact estimates;
3. An assessment of how the interactions
between potential demand-side rates and
potential demand-side programs would affect
the impact estimates of the potential demandside programs and potential demand-side
rates;
4. For each year of the planning horizon, an estimate of the incremental and
cumulative demand reduction and energy savings due to the potential demand-side rate;
and
5. For each year of the planning horizon, an estimate of the costs of each potential
demand-side rate, including:
A. The cost of incentives to customers to participate in the potential demandside rate paid by the utility. The utility shall
consider multiple levels of incentives to
achieve customer participation in each potential demand-side rate, with corresponding
adjustments to the maximum achievable
potential and the realistic achievable potentials of that potential demand-side rate;
B. The cost to the customer and to the
utility of technology to implement the potential demand-side rate;
C. The utility’s cost to administer the
potential demand-side rate; and
D. Other costs identified by the utility;
(E) A tabulation of the incremental and
cumulative number of participants, load
impacts, utility costs, and program participant costs in each year of the planning horizon for each potential demand-side program;
(F) Evaluate how each demand-side rate
would be considered by the utility’s Regional
Transmission Organization (RTO) in resource
adequacy determinations, eligibility to participate as a demand response resource in RTO
markets for energy, capacity, and ancillary
services; and
(G) The utility shall describe and document how it performed the assessments and
developed the estimates pursuant to subsection (4)(D) and shall document its sources
and quality of information.
(5) The utility shall describe and document
its evaluation of the cost effectiveness of each
potential demand-side program developed
pursuant to section (3) and each potential
demand-side rate developed pursuant to section (4). All costs and benefits shall be
expressed in nominal dollars.
(A) In each year of the planning horizon,
the benefits of each potential demand-side
program and each potential demand-side rate
shall be calculated as the cumulative demand
reduction multiplied by the avoided demand
cost plus the cumulative energy savings multiplied by the avoided energy cost. These calculations shall be performed both with and
without the avoided probable environmental
costs. The utility shall describe and document
the methods, data, and assumptions it used to
develop the avoided costs.
1. The utility avoided demand cost shall
include the capacity cost of generation, transmission, and distribution facilities, adjusted
to reflect reliability reserve margins and
capacity losses on the transmission and distribution systems, or the corresponding market-based equivalents of those costs. The utility shall describe and document how it
developed its avoided demand cost, and the
capacity cost chosen shall be consistent
throughout the triennial compliance filing.
2. The utility avoided energy cost shall
include the fuel costs, emission allowance
costs, and other variable operation and maintenance costs of generation facilities, adjusted
to reflect energy losses on the transmission
and distribution systems, or the corresponding market-based equivalents of those costs.
The utility shall describe and document how
it developed its avoided energy cost, and the
energy costs shall be consistent throughout
the triennial compliance filing.
3. The avoided probable environmental
costs include the effects of the probable environmental costs calculated pursuant to 4 CSR
240-22.040(2)(B) on the utility avoided
demand cost and the utility avoided energy
cost. The utility shall describe and document
how it developed its avoided probable environmental cost.
(B) The total resource cost test shall be
used to evaluate the cost effectiveness of the
potential demand-side programs and potential
demand-side rates. In each year of the planning horizon—
1. The costs of each potential demandside program shall be calculated as the sum
of all incremental costs of end-use measures
that are implemented due to the program
(including both utility and participant contributions) plus utility costs to administer,
deliver, and evaluate each potential demandside program;
2. The costs of each potential demandside rate shall be calculated as the sum of all
incremental costs that are due to the rate
(including both utility and participant contributions) plus utility costs to administer,
deliver, and evaluate each potential demandside rate; and
3. For purposes of this test, the costs of
potential demand-side programs and potential
demand-side rates shall not include lost revenues or utility incentive payments to customers.
(C) The utility cost test shall also be performed for purposes of comparison. In each
year of the planning horizon—
1. The costs of each potential demandside program and potential demand-side rate
shall be calculated as the sum of all utility
incentive payments plus utility costs to
administer, deliver, and evaluate each potential demand-side program or potential
demand-side rate;
2. For purposes of this test, the costs of
potential demand-side programs and potential
demand-side rates shall not include lost revenues; and
3. The costs shall include, but separately identify, the costs of any rate of return or
incentive included in the utility’s recovery of
demand-side program costs.
(D) The present value of program benefits
minus the present value of program costs over
the planning horizon must be positive or the
ratio of annualized benefits to annualized
costs must be greater than one (1) for a
potential demand-side program or potential
demand-side rate to pass the utility cost test
or the total resource cost test. The utility may
relax this criterion for programs that are
judged to have potential benefits that are not
captured by the estimated load impacts or
avoided costs, including programs required to
comply with legal mandates.
(E) The utility shall provide results of the
total resource cost test and the utility cost test
for each potential demand-side program evaluated pursuant to subsection (5)(B) and for
each potential demand–side rate evaluated
pursuant to subsection (5)(C) of this rule,
including a tabulation of the benefits (avoided
costs), demand-side resource costs, and net
benefits or costs.
(F) If the utility calculates values for other
tests to assist in the design of demand-side
programs or demand-side rates, the utility
shall describe and document the tests and
provide the results of those tests.
(G) The utility shall describe and document how it performed the cost effectiveness
assessments pursuant to section (5) and shall
describe and document its methods and its
sources and quality of information.
(6) Potential demand-side programs and
potential demand-side rates that pass the total
resource cost test including probable environmental costs shall be considered as demandside candidate resource options and must be
included in at least one (1) alternative
resource plan developed pursuant to 4 CSR
240-22.060(3).
(A) The utility may bundle demand-side
candidate resource options into portfolios, as
long as the requirements pursuant to section
(1) are met and as long as multiple demandside candidate resource options and portfolios
advance for consideration in the integrated
resource analysis in 4 CSR 240-22.060. The
utility shall describe and document how its
demand-side candidate resource options and
portfolios satisfy these requirements.
(B) For each demand-side candidate
resource option or portfolio, the utility shall
describe and document the time-differentiated load impact estimates over the planning
horizon at the level of detail required by the
supply system simulation model that is used
in the integrated resource analysis, including
a tabulation of the estimated annual change in
energy usage and in diversified demand for
each year in the planning horizon due to the
implementation of the candidate demand-side
resource option or portfolio.
(C) The utility shall describe and document its assessment of the potential uncertainty associated with the load impact estimates of the demand-side candidate resource
options or portfolios. The utility shall estimate—
1. The impact of the uncertainty concerning the customer participation levels by
estimating and comparing the maximum
achievable potential and realistic achievable
potential of each demand-side candidate
resource option or portfolio; and
2. The impact of uncertainty concerning
the cost effectiveness by identifying uncertain
factors affecting which end-use resources are
cost effective. The utility shall identify how
the menu of cost-effective end-use measures
changes with these uncertain factors and shall
estimate how these changes affect the load
impact estimates associated with the demandside candidate resource options.
(7) For each demand-side candidate resource
option identified in section (6), the utility
shall describe and document the general principles it will use to develop evaluation plans
pursuant to 4 CSR 240-22.070(8). The utility shall verify that the evaluation costs in subsections (5)(B) and (5)(C) are appropriate
and commensurate with these evaluation
plans and principles.
(8) Demand-side resources and load-building
programs shall be separately designed and
administered, and all costs shall be separately classified to permit a clear distinction
between demand-side resource costs and the
costs of load-building programs. The costs of
demand-side resource development that also
serve other functions shall be allocated
between the functions served.
