At the time of partition of India in the year 1947, Power Generation and distribution of this part of the country (present Bangladesh) was in the hands of some private companies.
The power supply to 17 districts was within the township in a limited way. Power used to be supplied to most of the district during the night time only and the supply voltage was 400 volts. Only exception was Dhaka City where power used to be supplied by 2 Nos. of 1500 KW generators and the generation voltage was 6.6 KV and this was the highest distribution voltage. Besides, power used to be generated by some industries and railway workshops. With all these the total power generation capacity in the country was 21 MW. The generation capacity of the power utility companies together was only 7 MW and there was no transmission system.
