Identifying the abuse of market power by generating firms in deregulated electricity markets is frequently difficult because the true costs of generation have become private information. This information is not disclosed to market operators except by special request. Rapid identification of market power abuse is increasingly important as government oversight of the market has been drastically reduced. The ability to visualize market power potential (MPP) in real time can aid in spotting trends in the abuse of market power and facilitate a better understanding of the complex dynamics of the deregulated energy market. This paper introduces a new technique for visualizing market power potential.
