Long Term Model USER MANUAL, February 2001 Available Installed Thermal Capacity Available Installed Hydro Capacity + 1+ RESTHM ( z ) 1+ RESHYD ( z ) + Reserves held by others to back up firm imports to z ( 1 - lineloss ) + UM ( z , ty ) ≥ Reserves 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 full equation is as follows (the expressions for installed capacity in year ty were explained in Chapter 3): existing thermal capacity + + + ty n(ty −τ ) + PGO exp step( ⋅ )∑ PGO exp ( τ ,z,i )( 1 − DecayPGO ) τ =1 ty NT exp step( ⋅ )∑ PGNT exp ( τ ,z,i )( 1 − DecayNT )n(ty −τ ) τ =1 ty + NSC exp step( ⋅ )∑ PGNSC exp ( τ ,z,ni )( 1 − DecayNSC )n(ty −τ ) τ =1 ty n(ty −τ ) PGNCCinit( ⋅ )∑ YCC( τ ,z,ni )( 1 − DecayNCC ) τ =1 ty n(ty −τ ) + NCC exp step( ⋅ )∑ PGNCC exp ( τ ,z,ni )( 1 − DecayNCC ) τ =1 ty PGNLCinit( ⋅ )∑ YLC( τ ,z,ni )( 1 − DecayNLC )n(ty −τ ) τ =1 ty + NLC exp step( ⋅ )∑ PGNLC exp ( τ ,z,ni )( 1 − DecayNLC )n(ty −τ ) ty =1 PGOinit( ⋅ )( 1 − DecayPGO )n(ty ) 1 + RESTHM (z ) 94
