The CCS chilled water Usage Charge Rate is reviewed and adjusted quarterly, and is calculated as follows:

Usage Charge = Metered quantities of Supply for the billing period in units of kilowatt-hours refrigeration (kWrh) x prevailing consumption Usage Charge Rate ($/kWrh)

The CCS Usage Charge covers the capital costs for the chiller plant and network pipes, operations and maintenance, CCS-related electricity and water consumption, and projected cooling energy consumption.
