Powerhouse costing categorizes expenses to ascertain the total cost of generating utilities such as steam, electricity, or gas.
Steam production involves two primary cost categories:
1. Fixed Costs: These costs remain constant irrespective of steam output volume.
Examples include boiler depreciation, permanent staff salaries, and equipment insurance premiums.
2. Variable Costs: These costs fluctuate in direct proportion to the volume of steam produced.
Illustrative examples encompass fuel expenses (coal, oil, or gas), water treatment, lubricants, and wages for any necessary temporary personnel.
Precise cost classification enables the calculation of the cost per unit of steam and facilitates effective cost management.
