Overview
West Bengal State Electricity Board (WBSEB) was the electricity authority established by the Government of West Bengal to organize and oversee the state's electricity system. It was formed on 1 May 1955 and operated as a state government electricity board rather than as a privately owned commercial brand. Its role was associated with the public provision and administration of electrical power across West Bengal, including functions that were later separated into transmission and distribution activities. The board remained the predecessor institution for major parts of West Bengal's modern electricity infrastructure. Its eventual restructuring took place in the context of India's electricity-sector reforms and the Electricity Act 2003. Under the West Bengal Power Reform Scheme, 2007, the erstwhile board was unbundled into two successor companies, both of which came into effect on 1 April 2007. West Bengal State Electricity Transmission Company Limited (WBSETCL) assumed responsibility for electricity transmission, while West Bengal State Electricity Distribution Company Limited (WBSEDCL) assumed responsibility for distribution. WBSETCL's stated transmission remit covers the movement of electricity through networks operating at 66 kV, 132 kV, 220 kV and 400 kV within West Bengal. WBSEDCL's distribution role covers supply at 33 kV and below. The unbundling therefore replaced the former integrated board structure with a functional division between high-voltage transmission and downstream distribution. The successor companies illustrate the institutional importance of WBSEB's legacy. WBSEDCL is described as a major state power utility, with a large consumer base and a distribution organization divided into six zones: Kolkata, Burdwan, Midnapore, Berhampore, Malda and Siliguri. Its operating structure includes regional offices, distribution divisions and customer-care centers. WBSETCL, meanwhile, became the transmission licensee responsible for the state's high-voltage network and received a Gold Shield, or Best Power Availability Award, for 2007–2008 from India's Ministry of Power. WBSEB is therefore best understood as a historical public electricity institution and predecessor organization, not as an active contemporary utility. Its operational identity ended with the 2007 restructuring, while its public-service functions continued through WBSEDCL and WBSETCL. The board's history reflects the broader transition in India from vertically integrated state electricity boards toward separately organized generation, transmission, distribution and regulatory functions.
History
West Bengal State Electricity Board was created on 1 May 1955 as a state government electricity board for West Bengal, India. It formed part of the post-independence model in which state electricity boards served as public institutions responsible for organizing and operating electricity systems within their respective states. WBSEB's historical significance lies in its role as the predecessor of the state's later transmission and distribution utilities. For much of its existence, the board represented an integrated public electricity structure. The later reform of India's electricity sector, including the Electricity Act 2003, encouraged clearer separation of functions within the power industry. In West Bengal, this process culminated in the West Bengal Power Reform Scheme, 2007. The erstwhile board was unbundled, and two successor companies were established with effect from 1 April 2007. West Bengal State Electricity Transmission Company Limited became responsible for transmission. Its network remit includes voltage levels of 66 kV, 132 kV, 220 kV and 400 kV. West Bengal State Electricity Distribution Company Limited became responsible for distribution at 33 kV and below. This division separated the high-voltage transport of electricity from the downstream delivery of power to consumers. The successor organizations retained and developed the public electricity functions associated with the former board. WBSEDCL is described as having a large consumer base and an extensive operating structure comprising six zones, 19 regional offices, 67 distribution divisions and 490 customer-care centers. Its zones are Kolkata, Burdwan, Midnapore, Berhampore, Malda and Siliguri. WBSETCL continued as the state's transmission licensee and was recognized with the Best Power Availability Award, or Gold Shield, for 2007–2008 by the Ministry of Power, Government of India. WBSEB is now defunct as an operating institution. Its formal identity ended through the 2007 restructuring rather than through bankruptcy, liquidation for financial distress or a corporate acquisition. The board's legacy survives institutionally through the transmission and distribution companies created from it. Its history is consequently tied to the modernization and unbundling of India's state electricity administration.

Public electricity utility service · 1955
Electricity administration
WBSEB's central function was the public administration and organization of electricity services in West Bengal. As a state electricity board, it represented an integrated institutional model rather than a consumer product brand. Its responsibilities were later divided between transmission and distribution entities during the 2007 reform.

Electricity transmission and distribution
The board's former integrated electricity role covered functions that were subsequently separated. WBSETCL assumed high-voltage transmission at 66 kV, 132 kV, 220 kV and 400 kV, while WBSEDCL assumed distribution at 33 kV and below. These successor activities represent the continuing institutional legacy of WBSEB.
Brand decisions
2007
Unbundle the state electricity boardStrategyBackground
Electricity-sector reform under the Electricity Act 2003 created the context for separating the functions of state electricity boards. West Bengal implemented this restructuring through the West Bengal Power Reform Scheme, 2007.
Action taken
The erstwhile WBSEB was divided into West Bengal State Electricity Transmission Company Limited for transmission and West Bengal State Electricity Distribution Company Limited for distribution. Both companies became effective on 1 April 2007.
Aftermath
WBSEB ceased to operate as an integrated electricity board. Its transmission and distribution responsibilities continued through the two successor state utilities.
