A regulatory concept used to represent the total net costs of a resource decision. The TRC is used by the California Public Utilities Commission (CPUC) and other regulatory jurisdictions as one of several benchmarks used to evaluate the cost-effectiveness of various programs, measures, and strategies.
Total Resource Cost
The cost to produce the next increment of a product or service. When used in water and energy resource planning, it is typically expressed as the incremental cost in $/unit to produce and/or deliver the next (marginal) resource, whether a gallon of water supply, a kilowatt or kilowatt-hour of electricity, or a therm of natural …
The last unit of supply needed to meet demand for a product or service. On a short‐run basis, the marginal supply is typically the last unit of resource – whether a water supply resource, a kilowatt hour, or a therm – used to meet demand. On a long‐run basis, the marginal supply is typically the …
A non-chronological, graphical summary of demand levels with corresponding time durations using a curve, which plots demand magnitude (power) on one axis and percent of time that the magnitude occurs on the other axis.
The average amount of energy used to collect, produce, transport, treat, deliver and/or to collect, treat, and/or dispose of wastewater (typically expressed in kWh/AF or kWh/MG).
