History of Electricity in Delhi
The position is that as per available records, the first diesel Power Station was established in Delhi in the year 1905 when a private English Company by name M/s. John Fleming was given permission to generate electricity under the provisions of the Indian Electricity Act 1903. The above-mentioned Company was given the responsibility both of generation and distribution of power in a limited manner. That Company after obtaining license under the provisions of Electricity Act 1903 had set up a small 2 MW Diesel set at Lahori Gate in Old Delhi. Later on, this very Company was converted as Delhi Electricity Supply and Traction Company. In the Year 1911, the power generation was augmented by Steam Generation Station. In the year 1932, the management of Central Power House was handed over to New Delhi Municipal Committee (NDMC). In the field of power generation and distribution, a major break through was achieved in 1939 when Delhi Central Electricity Power Authority (DCEPA) was established. This company was responsible for the supply of power to the areas covered by Local Bodies, namely, the Municipal Committees of Delhi, West Delhi and South Delhi, the Notified Area Committees of Red Fort, Civil Lines, Mehrauli, Najafgarh, and the District Board of Delhi. The supply of electricity to the Municipal Committees of Delhi-Shahdara and the Notified Area of Narela was done by different private agencies. In 1947 DCEPA took over a Private Limited Company by name Delhi electric Supply & traction Company Limited.
Formation of Delhi State Electricity Board (DSEB)
In the year 1951 the Delhi State Electricity Board (DSEB) came into existence and the responsibility of generation and distribution of electricity was taken over by DSEB from DCEPA.
Formation of Delhi Electric Supply Undertaking (DESU)
After the promulgation of the Delhi Municipal Corporation Act 1957, the DSEB was dissolved and the functions of DSEB were taken over by Delhi Electric Supply Undertaking (DESU), which came into existence in 1958. After the formation DESU, the generation and distribution of electricity to all the areas of Delhi came under DESU.
Formation of Delhi Vidyut Board (DVB)
The Government of the National Capital Territory of Delhi vide notification No. F.11 (10)/92-LSG /PF (II) dated 24.02.1997, issued under the Electricity (Supply) Act, 1948, constituted a separate Electricity Board, i.e. the Delhi Vidyut Board (DVB) for the NCT of Delhi w.e.f. 24.02.1997 for the purpose of generation and distribution of power to the entire area of NCT of Delhi except the areas falling within the jurisdiction of NDMC and Delhi Cantonment Board.

BRPL is responsible for distribution of power in Central, South and West Delhi. BYPL handles power distribution in East Delhi (Trans-Yamuna). NDPL distributes power in North and North-West Delhi.
