abstract：China’s power generation market top 5 five power generation groups. the company name that translated in Chinese Pinyin by vocal.

China's power generation market mainly includes five power generation modes: thermal power, hydropower, nuclear power, photovoltaic power generation and wind power. Thermal power accounts for half of the power generation market. Photovoltaic, wind power, hydropower and other clean energy "afterwaves" have developed rapidly and become a new growth point for power generation groups.

So, how many thermal power plants, hydropower plants, wind power plants, nuclear power plants and photovoltaic power plants are there under the five power generation groups? According to public information, in this period, we counted 2310 home appliance plants under the five power generation groups, of which the national energy group is the largest thermal power company and the national power investment is the largest new energy power generation company!
