Which wind farm is better among the three companies, Guodian Longyuan, Three Gorges New Energy, and Shenhua Guohua?

Shenhua Company Guohua Electric Power Company is the power sector of Shenhua Company and is mainly responsible for the development of thermal power, wind power, new energy power generation and other businesses. Collective wages, benefits, and work breaks can be determined by agreement or contract with Shenhua Guohua Company or in accordance with the statutory management system of the company's board of directors. The three head offices of Guodian, China Three Gorges and Shenhua are one of the 53 enterprises under central management - deputy ministerial level! The only difference is that Guodian and Three Gorges operate electricity as their main business, while Shenhua's main business is coal operation and also operates seven major sectors: electricity, railways, ports, shipping, coal-to-liquids, coal chemicals, and low-carbon energy research. Sorry, that's all I know.
