I don't know why the Ogra and gas authorities have not any plans to fix CNG loadshedding, and why they are doing unscheduled CNG loadshedding. I have seen many drivers standing on the roadside due to empty cylinders in Karachi. It is not necessary that everyone have a full fuel tank with a CNG cylinder, especially the public transport.
As Karachi is the commercial and economic hub of Pakistan. Here all kinds of transport move twenty-four hours such as goods transport, public transport etc. I have also seen ambulance has stranded because of an empty CNG cylinder.
Ogra and/or authorities suddenly announced CNG loadshedding after which every CNG station has a rush of vehicles in the filling station, waste a lot of time and suffer in their personal/official jobs.
If CNG loadshedding is necessary in winter, Ogra and/or authority can fix that problem by announcing that "CNG will be closed from 9pm to 9am daily."
This announcement will help people, and they will be mentally relaxed that CNG will be available at a particular time. The residential consumers can also have regular gas supply in this way. But in the current scenario people don't know when there will no gas and CNG and are also under mental stress in their lives.
