Standardisation of yield analyses for solar thermal power plants
Concentrating solar thermal power plants or short STE or CSP are expected to play an important role in the world’s future electricity supply. Thermal storage as essential part of a concentrating solar thermal power plant allows decoupling of solar energy harvest and electricity production. By this means, demand oriented power production can be realized. Time periods of low solar resource are bridged using hybridization with fossil fuel burners (or gas turbines/reciprocating engines).
Besides improvements in technical issues of the plants it is of vital importance for a broad market introduction to predict the electricity outcome and thus the financial revenues with highest possible precision. Both, the physical outcome of the plant and the cost/revenue balance are keys to project finance. In order to address this topic, DLR initiated a SolarPACES activity in 2009 with the goal of publishing a guideline on STE yield calculation. SolarPACES is an implementing agreement of the International Energy Agency dedicated to concentrating solar technologies. Together with experts from various research institutes and industry world-wide a framework for such a guideline was developed.
Funded by the German Federal Ministry for Economic Affairs and Energy the project CSPBankability was launched in 2014. The goal of this project was to develop a guideline document based on the existing framework developed in the SolarPACES expert group. The results of this national project are then used as drafts for the international expert group. By mid of 2016, the first version of this document was finalized and sent into a review process on SolarPACES level. In January 2017, the guideline document together with an appendix on terminology was published as SolarPACES report.
Apart from the documents already reviewed and published by the SolarPACES expert group, more appendix documents have been developed and internally reviewed by the CSPBankability consortium. These documents will be fed into the SolarPACES review process in the future. Although not having reached the same formal status as the SolarPACES published documents the additional appendixes are published to support users to work with the guideline.
The following SolarPACES approved documents are available for download.

The following documents are available as project reports of the CSPBankability project:
In addition to the text documents, a number of meteorological data files have been compiled and provided for download from the SolarPACES website.
