Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This rule defines terms used in the rules
				  comprising 4 CSR 240-22-Electric Utility Resource Planning.
(1) Acknowledgment is an action the
				commission may take with respect to the officially adopted resource acquisition
				strategy or any element of the resource acquisition strategy including the
				preferred resource plan. Acknowledgement means that the commission finds the
				preferred resource plan, resource acquisition strategy, or the specified
				element of the resource acquisition strategy to be reasonable at a specific
				date, typically the date of the filing of the utility's Chapter 22 compliance
				filing or the date that acknowledgment is given. Acknowledgment may be given in
				whole, in part, or not at all. Acknowledgment shall not be construed to mean or
				constitute a finding as to the prudence, pre-approval, or prior commission
				authorization of any specific project or group of projects.
(2) Annual update filing means the annual
				update report prepared by the utility in advance of the annual update workshop
				and the summary report prepared by the utility following the workshop as
				referenced in 4 CSR
				240-22.080(3).
(3) Candidate resource options are the
				potential demand-side resource options pursuant to
				4 CSR
				240-22.050(6) and the potential
				supply-side resource options pursuant to
				4 CSR
				240-22.040(4) that advance to be
				included in one (1) or more alternative resource plans.
(4) Capacity means the maximum capability to
				continuously produce and deliver electric power via supply-side resources or
				the avoidance of the need for this capability by demand-side
				resources.
(5) Coincident demand
				means the hourly demand of a component of system load at the hour of system
				peak demand within a specified interval of time.
(6) Concern means concerns with the electric
				utility's compliance with the provisions of this chapter, any major concerns
				with the methodologies or analyses required to be performed by this chapter,
				and anything that, while not rising to the level of a deficiency, may prevent
				the electric utility's resource acquisition strategy from effectively
				fulfilling the objectives of Chapter 22.
(7) Contingency resource plan means an
				alternative resource plan designed to enhance the utility's ability to respond
				quickly and appropriately to events or circumstances that would render the
				preferred resource plan obsolete.
(8) Critical uncertain factor is any
				uncertain factor that is likely to materially affect the outcome of the
				resource planning decision.
(9)
				Deficiency means deficiencies in the electric utility's compliance with the
				provisions of this chapter, any major deficiencies in the methodologies or
				analyses required to be performed by this chapter, and anything that would
				cause the electric utility's resource acquisition strategy to fail to meet the
				requirements identified in Chapter 22.
(10) Demand means the rate of electric power
				use measured in kilowatts (kW).
(11) Demand-side program means an organized
				process for packaging and delivering to a particular market segment a portfolio
				of end-use measures that is broad enough to include at least some measures that
				are appropriate for most members of the target market segment.
(12) Demand-side rate means a rate structure
				for retail electric service designed to reduce the net consumption or modify
				the time of consumption of a customer rate class.
(13) Demand-side resource is a demand-side
				program or a demand-side rate conducted by the utility to modify the net
				consumption of electricity on the retail customer's side of the meter. A
				load-building program or rate is not a demand-side resource.
(14) Describe and document refers to the
				demonstration of compliance with each provision of this chapter. Describe means
				the provision of information in the technical volume(s) of the triennial
				compliance filing, in sufficient detail to inform the stakeholders how the
				utility complied with each applicable requirement of Chapter 22, why that
				approach was chosen, and the results of its approach. The description in the
				technical volume(s), including narrative text, graphs, tables, and other
				pertinent information, shall be written in a manner that would allow a
				stakeholder to thoroughly assess the utility's resource acquisition strategy
				and each of its components. Document means the provision of all of the
				supporting information relating to the filed resource acquisition strategy
				pursuant to 4 CSR
				240-22.080(11).
(15) Distributed generation means a
				grid-connected electric generation system that is sized based on local load
				requirements and distributed primarily to the local load.
(16) Electric utility or utility means any
				electrical corporation as defined in section
				386.020, RSMo, which
				is subject to the jurisdiction of the commission.
(17) End-use energy service or energy service
				means the specific need that is served by the final use of energy, such as
				lighting, cooking, space heating, air conditioning, refrigeration, water
				heating, or motive power.
(18)
				End-use measure means an energy-efficiency measure or an energy-management
				measure.
(19) Energy means the
				total amount of electric power that is generated or used over a specified
				interval of time measured in kilowatt-hours (kWh).
(20) Energy-efficiency measure means any
				device, technology, or operating procedure that makes it possible to deliver an
				adequate level and quality of end-use energy service while using less energy
				than would otherwise be required.
(21) Energy-management measure means any
				device, technology, or operating procedure that makes it possible to alter the
				time pattern of electricity usage so as to require less generating capacity or
				to allow the electric power to be supplied from more fuel-efficient generating
				units. Energy-management measures are sometimes referred to as demand-response
				measures.
(22) Expected cost of an
				alternative resource plan is the statistical expectation of the cost of
				implementing that plan, contingent upon the uncertain factors and associated
				probabilities. The utility shall consider probable environmental costs as well
				as direct utility costs in its assessment of alternative resource
				plans.
(23) Expected unserved hours
				means the statistical expectation of the number of hours per year that a
				utility will be unable to supply its native load without importing emergency
				power.
(24) Historical period shall
				be the ten (10) most recent years or the period of time used as the basis of
				the utility's forecast, whichever is longer.
(25) Implementation period means the time
				interval between the triennial compliance filings required of each utility
				pursuant to 4 CSR 240-22.080.
(26) Implementation plan means descriptions
				and schedules for the major tasks necessary to implement the preferred resource
				plan over the implementation period.
(27) Information means any fact,
				relationship, insight, estimate, or expert judgment that narrows the range of
				uncertainty surrounding key decision variables or has the potential to
				substantially influence or alter resource-planning decisions.
(28) Legal mandates include applicable state
				and federal executive orders, legislation, court decisions, and applicable
				state and federal administrative agency orders, rules, and regulations
				affecting electric utility cost recovery mechanisms, loads, resources, or
				resource plans.
(29) Levelized cost
				means the dollar amount of a fixed annual payment for which a stream of those
				payments over a specified period of time is equal to a specified present value
				based on a specified rate of interest.
(30) Life-cycle cost means the present worth
				of costs over the lifetime of any device or means for delivering end-use energy
				service.
(31) Load-building program
				means an organized promotional effort by the utility to persuade energy-related
				decision-makers to choose electricity instead of other forms of energy for the
				provision of energy service or to persuade existing customers to increase their
				use of electricity, either by substituting electricity for other forms of
				energy or by increasing the level or variety of energy services used. This term
				is not intended to include the provision of technical or engineering
				assistance, information about filed rates and tariffs, or other forms of
				routine customer service.
(32) Load
				impact means the change in energy usage and the change in diversified demand
				during a specified interval of time due to the implementation of a demand-side
				resource.
(33) Load profile means a
				plot of hourly demand versus chronological hour of the day from the hour ending
				1:00 a.m. to the hour ending 12:00 midnight.

				level average hourly demands (kWhs per hour) derived from the metered
				instantaneous demand for each customer in the load-research sample.
(35) Long run means an analytical framework
				within which all factors of production are variable.
(36) Lost revenues means the reduction
				between rate cases in billed demand (kW) and energy (kWh) due to installed
				end-use measures, multiplied by the fixed-cost margin of the appropriate rate
				component.
(37) Major class is a
				cost-of-service class of the utility.
(38) Market imperfection means any factor or
				situation that contributes to inefficient energy-related choices by
				decision-makers, including at least:
(A)
				Inadequate information about costs, performance, and benefits of end-use
				measures;
(B) Inadequate marketing
				infrastructure or delivery channels for end-use measures;
(C) Inadequate financing options for end-use
				measures;
(D) Mismatched economic
				incentives resulting from situations where the person who pays the initial cost
				of an efficiency investment is different from the person who pays the operating
				costs associated with the chosen efficiency level;
(E) Ineffective economic incentives when
				decision-makers give low priority to energy-related choices because they have a
				short-term ownership perspective or because energy costs are a relatively small
				share of the total cost structure (for businesses) or of the total budget (for
				households); or
(F) Inefficient
				pricing of energy supplies.
