Namelist NLCOST'
Cost of heliostats including wiring; $/mz mirror surface.
Default: CH = 120.00 ($/m2) (V.A-1)
Cost of land including site preparation; $/m2.
Default: CL = 0.62 ($/m2) (V.A-2)
Wiring cost parameters; CW, total wiring cost in
$/heliostat, given by
CW = CWRXRAD + CWDRXRSEP + CWDAxAZMSEP
where RAD, RSEP, AZMSEP are calculated from variables in
the FIELD namelist. The cost CW is already included in
heliostat cost, but is separated by the code using this
algorithm.
Default: CWR = 0.03077 ($/m)
CWDR = 15.0 ($/m)
CWDA = 9.0 ($/m) (V.A-3)
Parameter for tower cost:
= 0, cost based on Sandia studies for concrete and steel towers;
= 1, user supplied values for CTOWl and CTOW2 to be used
for all THTB.
Default: ITHT = 0 (V. A-4)
Tower cost parameters; CTOW, tower cost in $, given by
CTOW = CTOWl x e"T0W2xTHTB
CTOW = CTOW3 x eXToWxTHTB
THTB 2 120.0(m)
THTB < 120.0(m)
where THTB is the actual tower height from the ground to
the receiver base.
Default: CTOWl = 0.78232 x loG($)
CTOW2 = 0.0113(l/m)
CTOW3 = 1.09025 x loG($)
XTOW = 0.00879(1/m) ( V . A-4)
Receiver cost parameters; CREC, receiver cost in $, given by:
CREC = CREC1' (AREC/ARECRF)XRE''
See text for definition of AREC and ARECRF for cavity designs.
Default: CRECl = 23.0~10~
ARECRF = 758 (m')
XREC = 0.8 (V.A-5)
* All reference powers in the cost models refer to the rated power at the design conditions,
not to the power at the base of the tower (unless the corresponding solar multiple is 1.0).
