FIGURE 3.67 Generating unit layout of Andasol-I power plant, Spain [32].

6. Location and transportation of the power plant. Identification of
location of traffic hub and the distance between the traffic hub
and the high-grade highways corresponding to the proposed
power plant is of great significance to power plant construction.
Due to the access of large-scale overheight and overweight
equipment, like the thermal storage tank, steam turbine, and boiler,
roads are required to have strong carrying capacities; due to the
transportation of a large quantity of glass reflectors, roads are
required to have high evenness. Thus grade of road, as well as
dimension of roads and bridges along the line, shall be given
special attention to; otherwise, it may lead to great expenses during
infrastructure construction.
Upwind area of power plant shall be free of large-scale air
pollution sources; otherwise, mirrors will be contaminated by dusts.
7. HV outlet orientation and passageway. Diagrams and texts for
receiving station of power plant outlet, conditions of cable
passageway, conditions of power outlet, etc. shall be provided.
8. Water source of power plant. Name and distance of the water
supplier shall be specified, as well as the respective daily water
supply capability, water price description, actual daily water supply
and annual total water supply.
9. Fuel transportation. Transportation method for engineering liquid,
gas or solid fuels, distance between the fuel supply point and the
plant area, whether there is any road of the appropriate grade in
Gobi areas for transportation; road with an uneven surface may
cause danger to fuel transportation.
