Five major electricity generation groups, constituting the bulk of China's power industry, are reported to have formally written to the central government, calling for a further electricity price increase. The five companies are China Datang Corporation, China Huaneng Group, China Huadian Corporation, China Power Investment Corporation and China Guodian Corporation. According to Information Times (in Chinese), this is the third time this year that China's main power producers have jointly lodged price-increase applications to the National Development and Reform Commission (NDRC) under the State Council in response to an increase in the price of coal, increasing government calls for nationwide reductions in pollution and rising power consumption. The NDRC expressed that more time is needed for further observation before making any changes to the price of electricity.
