Workshop

“POWER SECTOR TRENDS & ISSUES: TECHNICAL AND COMMERCIAL BENCHMARKING OF POWER PLANTS”

Mexico City, 4 November 2008

The KISSY - Database

What is KISSY?

  • KISSY is an abbreviation for the German

  • Kraftwerksinformationssystem –

  • which means: Power plants information system

a database managed by VGB,

which is an European association

an information system for thermal power plants

multilingual: Dutch, English, French, German, Italian,

Portuguese and soon in Danish

an online evaluation tool

It is possible to analyse component experiences

Basis are harmonized terms

Basis of every collaboration is a common understanding. Therefore VGB

  • defines performance indicators, terms, descriptions

  • and the necessary calculation-formulas

  • fixes rules for the data collection and

  • edits booklets to publish the results

WEC PGP, 4 November 2008

Basis are harmonized terms

Objective is to harmonize

  • the understanding of those defined indicators

  • the data collection of the input data

  • the calculation of the indicators and statistics and

  • the use of those indicators

  • Terms of utility industry

  • Part B

  • Power and District Heat

  • Booklet 3

  • Fundamentals and systematic of availability determinationfor Thermal Power Plants

  • 7th Edition 2008

The basic guideline

The VGB work group “Definitions” has actualised our fundamental

guideline. The English and German version were published in 2008 – also in a pdf-file. The French one will follow next year.

The definitions of the former

Unipede-indicators, that are

supported, are included.
