ABSTRACT:
A preliminary comparative evaluation of distributed-collector solar thermal power plants has been undertaken by projecting power plant economics of selected systems to the 1990-2000 time frame. The selected systems include: (1) fixed orientation (non-tracking) collectors with concentrating
Comparisons are presented primarily in terms of energy cost (mills/kWe hr) and capital cost over a wide range of operating load factors. Sensitivity of energy costs for a range of efficiency and cost of major subsystems/components is presented to delineate critical technological development needs. The baseline central receiver or power tower systems using state-of-the-art 1000°F steam Rankine technology is used as a reference case for making comparisons of the selected distributed collector systems.

reflectors and vacuum tube absorbers, (2) one-axis tracking linear concentrators including parabolic trough and variable slat designs, and (3) two-axis tracking parabolic dish systems including concepts with small heat engine-electric generator assemblies at each focal point as well as approaches having steam generators at the focal point with pipeline collection to a central power conversion unit.Comparisons are presented primarily in terms of energy cost (mills/kWe hr) and capital cost over a wide range of operating load factors.
