O&M Cost

← Previous | Next →

The O&M Cost parameter screen combines the variable O&M unit costs from all the model components and places them in one spot. These values will also appear in the technology input screens where they are actually used. Values changed on this screen will reflect exactly the same change everywhere else they appear. O&M costs are typically expressed on an average annual basis and are provided in either constant or current dollars for a specified year, as shown in the Status Bar.

The following costs may be specified:

•Activated Carbon Cost: This is the unit cost of activated carbon.

•Alum Cost: This is the unit cost of alum.

•Ammonia Cost: This is the unit cost of ammonia.

•Caustic (NaOH) Cost: This is the unit cost of caustic (NaOH) gas.

•Dibasic Acid Cost: This is the unit cost of dibasic acid.

•Flocculant Polymer Cost: This is the unit cost of flocculant polymer.

•Lime Cost: This is the unit cost of lime.

•Limestone Cost: This is the unit cost of limestone.

•MEA/Amines Cost: This is the unit cost of MEA.

•SCR Catalyst Cost: This is the unit cost of SCR catalyst.

•Urea Cost: This is the unit cost of urea.

•Water Cost: This is the unit cost of water.

•Hydrated Lime Cost: This is the unit cost of hydrated lime.

•Taxes & Insurance: This is the cost of taxes and insurance. This parameter is included as fixed O&M costs and is estimated empirically as a percent of the TPC.

•Operating Labor Rate: This is the hourly cost of labor. This same value is used throughout the individual technologies. (See O&M Cost Inputs.)

•Real Escalation Rate (for all above) (%/yr): This is the annual rate of increase of an expenditure due to factors such as resource depletion, increased demand, and improvements in design, manufacturing or construction techniques (negative rate). The real escalation rate does not include inflation.
