Use of Power Guide Curve Rule in HEC-ResSim

In this post, I have developed a simple reservoir network with one reservoir.  The schematic is shown below.




This reservoir has a powerplant with the following characteristics:

Hydraulic capacity = 500 cfs
Installed capacity = 2 MW
Efficiency is a constant 80%
Constant tailwater of 25 ft

The installed capacity tab of the power plant is shown below.



The following top of zone elevations are used in the operations set.  They are constant throughout the entire year.  
Top of flood = 100 ft Top of conservation = 75 ft Top of inactive = 50 ft
These are shown in the figure below.


For this example, a Power Guide Curve Rule is used.  This rule specifies that the power pool is from the top of conservation (75 ft) to the top of inactive (50 ft).  The rule is shown below.  A plant factor of 50% is specified when 0.0% to 49.999% of the power pool is in use.  A plant factor of 100% is specified when 50.0% to 100.0% of the power pool is in use. 
The plant factor specifies how much of the installed c…
