Some small hydropower stations in Foshan have attached great importance to operation and management. The power station workers have achieved remarkable results in improving the output of power plants and increasing the amount of power generation after technical renovation of existing buildings or equipment (see the attached table on page 47). The brief introduction is as follows : I.
