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

V.A-9. WirineThe calculated wiring costs are assumed to be included in
the input heliostat cost, and are calculated and separated from heliostat costs by
DELSOL according to the following:
zones
CWIRE = (CW,RRi -k CW,ARARi.+ CW,AAZAAzi)
i
x number of heliostats in zone i
where Ri = radial distance from the tower base to zone i
ARi = average row spacing in zone i
AAzi = average spacinb between heliostats on the same
row in zone i.

This model was supplied with the field performance results from Reference 9. It
is designed to penalize heliostats placed farther out due to requirements of larger
(or more) primary cables as the field grows radially from the tower, and longer
plowed-in secondary line runs as the mirror density decreases with distance from
the tower. From the defined zoning and density option in namelists FIELD and
OPT, Ri, AR;, and AAzi are known. Default values for the wiring cost parame-
ters, given for a single heliostat and as provided in Reference 35, are:
C~,R(CWR) = $0.03077/m
CW,AR(CWDR) = $15.00/m
CW,AA~ (C WDA) = $9.0O/m
