| Summary: | This paper provides estimates of the levelized energy cost (LEC) of a mid-temperature parabolic trough system for three different development scenarios. A current technology case is developed that is representative of recent designs and costs for commercial systems, and is developed using data from a recent system installed in Tehachapi, California. The second scenario looks at design enhancements to the currenttechnology case as a way to increase annual energy output and decrease costs. The third scenario uses the annual energy output of the enhanced design, but allows for cost reductions that would be possible in higher volume production than currently exist. A simulation model was used to estimate the annual energy output from the system, and the results were combined with cost data in an economic analysis model. The study indicates that R D improvements in the current trough system show promise of reducing the (LEC) by about 40%. At higher production rates, the LEC of the solar system with R D improvements could potentially be reduced by over 50% |
