Excuse me: How many branches does State Grid have in Beijing? Thank you.

The problem is not very professional, and the specific figures are not clear. State Grid is the head office, with power grid companies in North China, Central China, Northwest China and Northeast China, and power grid companies have provincial companies. Beijing Power Supply Company belongs to North China Power Grid Corporation. Beijing Company has branches in Changping, Fengtai, Daxing, Chaoyang and Pinggu, as well as design companies and EHV companies. The specific figures don't count.
