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.
