Abstract :
Summary form only given, as follows. The success of the PJM power market (USA) is driven by making as much data available to the market participants as possible. As a result, PJM developed a set of guidelines, called the PJM Data Plan, for the categorization of PJM data as either confidential or public. This presentation provides a summary of the data plan, as well as a discussion of the process used in the development of the Data Plan and how it is applied. The presentation also discusses the other issues that impact data publication.
