ABSTRACT
The literature on electricity market structure, reforms, and performance is voluminous. Most of the research is at the aggregate level and often covers only the distribution segment of the market. This study focuses on the generation part and is at the generator level. In addition, we consider different levels of aggregation, ranging from the disaggregated generator to plant, business unit, company, and industry levels. The main focus is on the performance of the generator units and its distribution. We use both parametric and non-parametric approaches for the analysis of performance in the Korean electricity generation industry. The empirical result is based on a unique and newly created database at the generator level covering the industry during the period 2001-2008. A comprehensive and up-todate picture of the generation in the industry and its performance and changes over time is provided. Information on the state of performance and its variations is expected to serve as base for corrective and effective policy measures.
