Current through Register Vol. 48, No. 1, January 10, 2025

Section 4 CCR 723-3-3602 - Definitions

The following definitions apply to rules 3600 through 3619. In the event of a conflict between these definitions and a statutory definition, the statutory definition shall apply.

(a) "Availability factor" means the ratio of the time a generation facility is available to produce energy at its rated capacity, to the total amount of time in the period being measured.

(b) "Annual capacity factor" means the ratio of the net energy produced by a generation facility in a year, to the amount of energy that could have been produced if the facility operated continuously at full capacity year round.

(c) "Cost-effective resource plan" means a designated combination of new resources that the Commission determines can be acquired at a reasonable cost and rate impact.

(d) "Demand-side resources" means energy efficiency, energy conservation, load management, and demand response or any combination of these measures.

(e) "End-use" means the light, heat, cooling, refrigeration, motor drive, or other useful work produced by equipment that uses electricity or its substitutes.

(f) "Energy conservation" means the decrease in electricity requirements of specific customers during any selected time period, resulting in a reduction in end-use services.

(g) "Energy efficiency" means the decrease in electricity requirements of specific customers during any selected period with end-use services of such customers held constant.

(h) "Heat rate" means the ratio of energy inputs used by a generation facility expressed in BTUs (British Thermal Units), to the energy output of that facility expressed in kWh.

(i) "Modeling error or omission" means any incorrect, incomplete, or improper input to computer-based modeling performed by the utility, for evaluating a proposed resource, of a magnitude that alters the model results.

(j) "Net present value of revenue requirements" means the current worth of the total expected future revenue requirements associated with a particular resource portfolio, expressed in dollars in the year the plan is filed as discounted by the appropriate discount rate.

(k) "Planning period" means the future period for which a utility develops its plan, and the period, over which net present value of revenue requirements for resources are calculated. For purposes of this rule, the planning period is twenty to forty years and begins from the date the utility files its plan with the Commission.

(l) "Potential resource" means a generation facility or energy storage system bid into a competitive acquisition process in accordance with an approved resource plan.

(m) "Renewable energy resources" means all renewable energy resources as defined in the Commission's RES Rules.

(n) "Resource acquisition period" means the first six to ten years of the planning period, in which the utility acquires specific resources to meet projected electric system demand and energy requirements. The resource acquisition period begins from the date the utility files its plan with the Commission.

(o) "Resource plan" or "plan" means a utility plan consisting of the elements set forth in rule 3604.

(p) "Resources" means supply-side resources, energy storage systems and demand-side resources used to meet electric system requirements.

(q) "Section 123 resources" means new energy technology or demonstration projects, including new clean energy or energy-efficient technologies under § 40-2-123(1)(a), C.R.S. and § 40-2-123(1)(c), C.R.S., and Integrated Gasification Combined Cycle projects under § 40-2-123(2), C.R.S.

(r) "Supply-side resources" means resources that provide electrical energy or capacity to the utility. Supply-side resources include utility owned generation facilities and energy or capacity purchased from other utilities and non-utilities.

(s) "Typical day load pattern" means the electric demand placed on the utility's system for each hour of the day.
