You can specify Annually Recurring OM&R Costs (other than energy or water costs) separately for each component if the alternative is subdivided into more than one capital component. Annually Recurring OM&R Costs occur in approximately the same amount every year over the service period or change at a relatively constant rate.
Amount ($)
Enter Annually Recurring OM&R Costs in base-year dollars.
Annual Rate of Increase (%)
Enter the average annual rate at which the base-year dollar amount of the Annually Recurring
OM&R Cost is expected to change throughout the Study Period. If the analysis is conducted in
constant dollars enter the real rate (excluding inflation), otherwise enter the nominal rate
(including inflation).
OM&R Usage Indices
If you expect the annual OM&R usage to change in some predictable manner (e.g., when ECMs are phased in
over a period of time), you can enter OM&R Usage Indices and their duration for each OM&R Cost. For
example, you might enter an index of 100 for OM&R for the first year of the service period and
adjust the usage downward as new ECMs come on line.
