At present, about 20 600MW units have been put into operation in China, but there are no 600MW units in the whole northwest and southwest regions. Therefore, the construction of Pannan Power Plant is not only a milestone in the history of Guizhou electric power development, but also a milestone in the history of western China electric power development, regardless of the single machine capacity or power plant scale. Pannan Power Plant is jointly built by Guangdong Yuedian Group (accounting for 55%) and Guizhou Xidian Power Co., Ltd. (accounting for 45%). The production and operation of Pannan Power Plant will be scientifically managed and standardized in strict accordance with the modern enterprise system. In addition to partially meeting the internal power demand of Guizhou Province, its power supply is also one of the main power sources for "Power Transmission from West to East" and "Power Transmission from Guizhou to Guangdong". The construction of Pannan Power Plant, which has been listed as the top of the "Ten Major Events" by Guizhou provincial government for two consecutive years, is the result of implementing the strategy of developing the western region. Its construction and commissioning will be another example of a win-win situation between the east and the west.
