The Kerala State Electricity Board (KSEB) is the state-owned public sector utility responsible for the generation, transmission and distribution of electricity in the Indian state of Kerala. It is one of the principal infrastructure organisations of the state, supplying power to domestic, commercial, agricultural and industrial consumers across all fourteen districts.

KSEB was constituted as a statutory body under the Electricity (Supply) Act, 1948, soon after the formation of the State of Kerala in 1956. For decades it functioned as a vertically integrated utility carrying out the generation of electricity, the operation of the state-wide high-voltage transmission network, and retail distribution to end consumers. Hydroelectric generation, drawing on the rivers and reservoirs of the Western Ghats, has historically formed the backbone of its installed capacity, supplemented by thermal stations, wind generation and power purchased from central generating stations and the open market.
Before the formation of Kerala, electricity supply in the region was administered by the erstwhile princely states of Travancore and Cochin and by the Madras Presidency. The Pallivasal Hydroelectric Project, commissioned in the 1940s in the Idukki region, was among the earliest large-scale generating stations and remained an important asset when the new Board took over electricity operations in the unified state.
Following the enactment of the Electricity Act, 2003, which mandated the unbundling and corporatisation of state electricity boards across India, the Government of Kerala restructured KSEB into a company. The successor entity, Kerala State Electricity Board Limited (KSEBL), was incorporated under the Companies Act, with the Government of Kerala as its sole shareholder. KSEBL continues to carry out the generation, transmission and distribution functions previously performed by the Board.
The utility operates a fleet of hydroelectric stations located largely in the high ranges of the Western Ghats. Major hydro stations associated with KSEB include:
Thermal generation has included the Brahmapuram and Kozhikode diesel stations. Power supply is also augmented through allocations from central sector stations and through purchases from the inter-state grid.
KSEB owns and operates the intra-state transmission system at 400 kV, 220 kV, 110 kV and 66 kV levels, along with the sub-transmission and distribution network at 33 kV, 11 kV and lower voltages. The distribution network is administered through a hierarchy of regional, circle, division, sub-division and section offices spread across the state. Kerala is among the Indian states with near-universal household electrification.
Tariffs, performance standards and licensing matters are governed by the Kerala State Electricity Regulatory Commission (KSERC), constituted under the Electricity Regulatory Commissions Act and continued under the Electricity Act, 2003. Disputes and consumer grievances are addressed through forums established under the regulatory framework.
As the dominant electricity utility of Kerala, KSEB plays a central role in the state's economy and public services. Its hydro-dominated generation profile makes Kerala one of the relatively low-carbon electricity systems in India, although the dependence on monsoon inflows has historically made the state vulnerable to hydrological shortfalls and reliant on imported power during dry years. The utility is also a major public employer in the state.
