Fields of heliostat mirrors focus sunlight on receivers located on centralized solar power towers. The receivers generate steam to drive specially adapted steam turbines. For the first plant, the largest-ever fully solar-powered steam turbine generator set was ordered, with a 123 MW Siemens SST-900 single-casing reheat turbine. [19]
A solar power tower consists of an array of dual-axis tracking reflectors that concentrate sunlight on a central receiver atop a tower; the receiver contains a heat-transfer fluid, which can consist of water-steam or molten salt. Optically a solar power tower is the same as a circular Fresnel reflector.
As solar power towers commonly use steam to drive the turbines, and water tends to be scarce in regions with high solar energy, another advantage of open pits is that they tend to collect water, having been dug below the water table. The Pit Power Tower uses low heat steam to drive the pneumatic tubes in a co-generation system.
Solar thermal power can also be converted to electricity by using the steam generated from the heated water to drive a turbine connected to a generator. However, because generating electricity this way is much more expensive than photovoltaic power plants, there are very few in use today.
The average concentrated solar power plant in the US occupied 2.7 acres (1.1 ha) of disturbed area and 3.5 acres (1.4 ha) of total area per GWh/yr, [38] A 2015 life-cycle analysis of land use for various sources of electricity concluded that concentrating solar power had a land-use footprint of 9.0 m 2 /MWhr for trough, and 14 m 2 /MWhr for ...
Nevada Solar One is a concentrated solar power plant, with a nominal capacity of 64 MW and maximum steam turbine power output up to 72 MW net (75 MW gross), spread over an area of 400 acres (160 ha). The projected CO 2 emissions avoided are equivalent to taking approximately 20,000 cars off the road.
