History

Electricity utilization in this region (Bangladesh) started in 1901 when a private generator was installed at the residence of the then Nawab of Dhaka.

Mr. Bolton, British citizen, switched on the first electricity in Ahsan Monjil on 7 December 1901.

Electricity distribution system under private ownership was begum by DEVCO, a subsidiary of Octttavian Steel Company in the 1930s and Dhanmondi power house was setup for commercial distribution of power.



HistoryIn the year 1947, power generation and distribution of this

part of the country were in the hands of some private companies.

The power supply to then 17 provincial districts was within the township in a limited way.The generation voltage was 400 volts. Power used to be supplied to most of the districts during nighttime only.

Only exception was Dhaka City where power used to be supplied by two 1500 kW generators and the generation voltage was 6.6 kV and this was the highest supply voltage.

There was no long distance transmission lines. In aggregate the generation capacity of the country was

21 MW.


Power Scenario in BangladeshHistory

In 1948, Electricity Directorate was created in order to plan and improve power supply situation.

In 1959, Water and Power Development Authority (WAPDA) was created and the power sector really started working satisfactorily.

In 1960, Electricity Directorate was merged with WAPDA. The basic philosophy was to give more autonomy to an organization for development of this basic infrastructure.


Power Scenario in BangladeshHistory

At that time (1960) relatively higher capacity plants were built at Siddhirganj, Chittagong and Khulna (highest plant size was only 10 MW Steam Turbine at Siddirganj).

At the same time, Kaptai dam was under construction under Irrigation department. Unit size of Kaptai was 40 MW, which for that time was considered to be a large power plant.

Side by side construction of Dhaka-Chittagong 132 KV transmission line was in progress.

Construction of Kaptai dam and commissioning of Dhaka-Chittagong 132 KV transmission line in the year 1962 may be taken as milestone of power development of this country.



History

In 1972, Bangladesh Power Development Board (BPDB) was created to boost the power sector.

A different approach and a new model was considered for undertaking a comprehensive scheme. Thus the Government created Rural Electrification Board (REB) in October 1977.

Later in 1991 Dhaka Electric Supply Authority (DESA) was created basically to operate and develop distribution system in and around Dhaka (including the metropolitan city) and bring about improvement of customer service, collection of revenue and lessen the administrative burden of BPDB.
