Since 1970 VGB has collected data based on standardized definitions, calculation methods, and recording procedures for power plants. With the liberalization of the energy markets the technical and economic assessment of power plants has gained more and more in importance. Intensifying the co-operation between Eurelectric and VGB it was decided to merge both associations’ data collection for the availability and unavailability of power plants. Since 2008 the data of Eurelectric ́s TherPerf-Report and VGB ́s KISSY-Report has been presented in one common report. This report provides information about the availability and utilization. It analyses the unavailability of components of thermal power plants all over Europe in order to compare the quality of power plants and to assess plants ́ behavior in daily operation. Reasons for unavailability have been collected since 1988 in order to identify and to assess the root cause (systems and main components) and to give hints to countersteer.
The VGB Technical Group “Performance Indicators” (TGPI) retrofitted and upgraded the VGB power plant information system (KISSY) in order to be able to provide up-to-date technical benchmark reports in real time. The participating utilities are able to analyze the data online within their companies. Currently the German, English, French, Italian, Dutch, and Portuguese languages are supported. The online analysis tool enables both the use of already implemented parameters and the evaluation with newly defined parameters, which are added by the TGPI. Commercial background information (e.g. EEX data) will also be included in the KISSY system. Analogues to the multilingual KISSY database the associated guidelines are also published in different national languages. The former VGB Guidelines “Availability of Thermal Power Plants”, “Unavailability of Thermal Power Plants” and “EMS Event Criterion Key Systems” were updated with the newly defined parameters and merged into one, completely revised guideline. The English, French and German versions are already placed on the VGB homepage (“Member information”) and can be downloaded.
This report covers the analysis for the period 2009 to 2018 with the individual data for the year 2018.
Previous editions of the reports (VGB-TW 103Ae and VGB-TW 103Ve) are available on request, e-mail: mark@vgb.org
