Due to the unstable gas pressure and gas production of some natural gas edge wells, the cost of laying natural gas pipelines and erecting power transmission lines is high. 

Therefore, natural gas generator sets are used to generate electricity at the wellhead, provide electricity to the CNG compressor, and inject the wellhead gas into the natural gas pipeline network. 

The decompression skid also requires a gas generator set to supply power to heat and reduce the pressure of the CNG
