China power industry is on the way to a deregulated electricity market since the industry restructuring in 2002. The integrated generation and transmission has been regrouped into five independent generation companies and two grid companies. The regional grid companies act as the system operators and exchange centers for the regional electricity markets. The customer side is still regulated by the government. In this paper, we will introduce the situation of China power industry restructuring. Some issues will be discussed for the current regional electricity markets, such as, electricity price policy, renewable energy policy, investment and planning issues. © 2006 IEEE. ; published_or_final_version

Power industry is undergoing restructuring throughout the world. The traditional vertically monopolistic structure has been deregulated and replaced by gencos, transcos and discos with competition introduced to gencos and discos in order to reach higher efficiency in electricity production and utilization. A lot of power markets have been established for the purpose. However for different countries, the principal objectives and considerations of power system deregulation are different. In this paper special considerations on power system deregulation of developing countries in Asia are discussed. Two regional power markets in China are used as examples. It is shown that for developing countries, the main objectives of power system deregulation are to attract various investments to power industry in order to meet the fast growth of electric demand caused by blooming economy and in the meantime to reduce government commitment and functions in power industry. Only this way, the power industry, as a significant infrastructure, can realize sustainable development at high efficiency. It is also shown that in the market environment, how to realize optimal system planning and reliable operation at acceptable electricity prices with qualifies service and how to transit to the market environment smoothly at lowest costs and lowest risks should be considered thoroughly. © 2005 IEEE. ; published_or_final_version
