An effective and reasonable surveillance system is the guarantee of realizing "fair and open trade" in electricity market. This article classifies the information needed by the surveillance system and illustrates the approaches to acquire information from grid companies, power plants and ISO. Each information included is also presented. Furthermore, this paper studies how to evaluate the "robustness" of an electricity market and presents two indexes to score the market operation and three relative indexes to judge the legitimacy of power plants' dealings. Based on the study above, a principle for all the market participants to publish their own information is suggested.
