Rate Schedule Setup

Before you set up an efficiency report, set up a Rate schedule that defines the efficiency
calculation. Enter the efficiency calculation in Line Item 1 in the rate schedule. Set up the
line item script to perform the efficiency calculation and set the Quantity variable to the
result. A sample line item script for calculating boiler efficiency (in British units) is
provided below:

Dim avg_gas, avg_steam

avg_steam=Average(ValueType.SteamFlow)

avg_gas=Average(ValueType.GasFlow)

if avg_gas=0

Quantity=0

else

Quantity=avg_steam*99.4 / avg_gas

end if
