Introduction  With the rapid expansion of the city, underground municipal engineering construction has been widely used. Underground municipal engineering has special requirements such as complex construction technology, wide space volume and installation limitation of process equipment.

  Method  According to the above characteristics, combining with the relevant specification requirements and engineering examples, this paper expounded the current underground municipal engineering design of power supply and distribution system and automatic control design.

  Result  The design ideas in load grade determination, energy saving optimization design, intelligent control, energy consumption management and other aspects are put forward, and some ideas and suggestions in energy saving, new energy are also put forward.

  Conclusion  The main points of electrical design of underground municipal engineering are discussed and summarized, which can provide some reference for similar design.
