Available Installed Thermal Capacity

Available Installed Hydro Capacity
1+RESHYD(z )
+ Reserves held by others to back up firm imports to"z" ( 1 - lineloss ) + UM ( z , ty )
− Re serves held by "z" to back up firm exports to others ≥ [ PeakD(z )*dgr (z ,ty ) − LM (z, th) ][ DLC (z ) ]
Note that the choice of RESTHM and RESHYD are behavioral choices; values can be
entered to reflect each SAPP member’s attitudes. The choice of FORICN and FORICO,
however, are set by the reliability of the lines connecting zp and z.
The full equation is as follows;
