The use of modelling techniques in the definition of the UK electricity market
AbstractThe electricity market in Great Britain has been progressively de-regulated over the last fifteen years. Competition has increased at an exponential rate during this period as new companies have begun operating in the market, which is now arguably the most sophisticated and successful competitive utility market in the world. This success has been achieved only with a degree of complexity. There are now more than a hundred “organisations” that must inter operate, where prior to competition there were only about twenty, operating independently. An organisation in this sense is an identifiable business unit carrying out one of more than a dozen defined roles. Within this complex structure individual organisations need to know their responsibilities and the processes for carrying out market transactions must be defined. (e.g. a customer wishing to change supplier) This requirement has been met by the production of an “industry model” which comprises a series of diagrams, formal definitions and English prose. These are delivered using a combination of a proprietary business modelling tool, a database and textual documents. In this paper the model is explored and an attempt made to classify its components by relating them to the Zachman framework. From this the model’s strengths and weaknesses are postulated. These are then tested by means of a survey of the intended users of the model. Finally, conclusions are drawn about the use of modelling techniques for the definition of a utility industry infrastructure, and recommendations for further research are made.
