<strong>for</strong> meteorological equipment. The default value is CH = $120.0/m2 of heliostat<br />
area, which applies to a high reflectivity glass-metal heliostat. This value is con-<br />
sistent with stated near-term cost goals of the 1984 five year plan.<br />
V.A-2. Land-The cost of land should be the cost of unimproved land. The<br />
area of land needed includes all of the land in each zone, increased by 30% to<br />
account <strong>for</strong> roads and additional land around the field, and increased by a fixed<br />
amount to account <strong>for</strong> the core area of the plant.<br />

{ = CL land area x 1.3 -t 0.18E6m2<br />
The default value is CL (CL) = $0.62/m2 of land area.<br />

V.A-9. WirineThe calculated wiring costs are assumed to be included in<br />
the input heliostat cost, and are calculated and separated from heliostat costs by<br />
DELSOL according to the following:<br />
zones<br />
CWIRE = (CW,RRi -k CW,ARARi.+ CW,AAZAAzi)<br />
i<br />
x number of heliostats in zone i<br />
where Ri = radial distance from the tower base to zone i<br />
ARi = average row spacing in zone i<br />
AAzi = average spacinb between heliostats on the same<br />
row in zone i.<br />
(V.A - 4)<br />
This model was supplied with the field per<strong>for</strong>mance results from Reference 9. It<br />
is designed to penalize heliostats placed farther out due to requirements of larger<br />
(or more) primary cables as the field grows radially from the tower, and longer<br />
plowed-in secondary line runs as the mirror density decreases with distance from<br />
the tower. From the defined zoning and density option in namelists FIELD and<br />
OPT, Ri, AR;, and AAzi are known. Default values <strong>for</strong> the wiring cost parame-<br />
ters, given <strong>for</strong> a single heliostat and as provided in Reference 35, are:<br />
C~,R(CWR) = $0.03077/m<br />
CW,AR(CWDR) = $15.00/m<br />
CW,AA~ (C WDA) = $9.0O/m<br />
