Kerala State Electricity Board Ltd (KSEBLtd) is a public sector undertaking under the Government of Kerala, India, that generates, transmits and distributes electricity in the state. Established in 1957, the agency comes under the authority of the Department of Power. It has been registered under Indian companies act during January 2011.


  • The history of electricity in the state is around one century old. The first effort in this direction was a private endeavour. Electricity was first brought to the state by a British company – the Kannan Devan Hill Produce Company, Munnar. The first generating station of the state was set up on the right bank of a tributary of River Periyar in 1910. It was a hydroelectric project and that tributary named Mudirappuzha continues to be the site of large a number of hydroelectric projects in the state.
  • After a spell of 17 years, the attention of the state authorities turned to newer forms of generating energy. The Government of Travancore set up a facility to supply electricity to the households of Thiruvananthapuram town. In 1927, a Thermal Power Station was established under government ownership at Thiruvananthapuram for production of electrical energy on commercial lines. Three oil engine generators, of a capacity of 65 kW each, were installed and commercial production started in 1929. This station was located at Thampanoor at Thiruvananthapuram. An Electrical Wing under the State Public Works Department was entrusted with the administration of the scheme.
  • The next significant development was the formation of a separate department for electricity in 1932 by His Highness Sri Chithirathirunal Maharaja and his Diwan Sir C P Ramaswami Iyer. The formation of the Electricity Department paved the way for notable developments in the field. Thermal generating stations were set up at Kollam, Kottayam and Nagercoil (now in Tamil Nadu) in 1934. By that time, the possibilities of hydroelectric generation attracted the attention of the technologists and the authorities.
  • Kerala being a land of mountains and rivers, it presented a fertile field for hydroelectric generation. The vast potential for hydroelectric generation in the state prompted the state authorities to take steps to establish stations for hydroelectric generation. The first of these ventures was the Pallivasal Hydroelectric Project, the construction of which was started in 1933. The first stage of the project was commissioned in 1940. Its capacity was 13.5 MW. By that time, a comparable electric transmission network had also been completed with 66 kV substations at Alappuzha, Mavelikkara, Kothamangalam, Kundara, Kalamasserry, Viyyur, Aluva, and Thiruvananthapuram, which were also commissioned in 1940 itself during April -May months
  • The Kerala state Electricity board started functioning under the direction of a newly formed Kerala government, on 31 March 1957.[1] The first governing body consisted of 5 members, and was headed by the chairman K P Sreedhara Kaymal. The staff of the erstwhile Department of Electricity of the Thiru-Kochi state were transferred to the KSEB.
  • At the time of its inception, in 1958, the KSEB had an installed capacity of 109.5 MW, with a total annual internal generation of 441.35 MU. Over the years, as demand increased, the board has imported power from neighbouring states and private entities. As per the Central Electricity Act 2003, KSEB was converted to Kerala State Electricity Board Limited in 2014. The original KSEB was dissolved and its assets and liabilities transferred to the government initially and then transferred to the newly formed company KSEB Limited.

Organizational Structure[edit]

The Kerala State Electricity Board, constituted by the Government of Kerala, by order dated 7 March 1957, under the Electricity (Supply) Act, 1948 is in the business of Generation, Transmission and Distribution of electricity and striving to provide quality electricity[clarification needed] at affordable cost to all classes of consumers in the state of Kerala.Kerala State Electricity Board commenced functioning on 31 March 1957 After Noon as per order no. EL1-6475/56/PW dated 7 March 1957 of the Kerala State Government. It had 5 members with Sri K P Sreedharan Nair as chairman.

KSEB Ltd has 31 hydro-electric projects, 7 solar projects, 2 diesel power plants and 1 wind farm. Power generation is also undertaken by Captive Mode Projects, Independent Power Mode Projects & Co-generation mode projects other than KSEBL. About 25% of the energy requirement is being met from hydel plants owned and operated by KSEBL. As of December 2019, The total installed capacity was 2823.01 MW.

The below list contains power generation projects in Kerala owned by KSEB, Captive Mode Projects, Independent Power Mode Projects & Co-generation mode projects.

Electricity Tariff[edit]

Kerala State Electricity Board Tariff consists of different components. The charges levied on consumers include Fixed Charges, Meter Rent, Energy Charges, Fuel Surcharges, Electricity Duty and applicable local taxes.

KSEB follows a slab system in which a consumer using up to 250 units per month will have a telescopic tariff. This means that the first 50 units will be charged at a lower rate, with the rates increasing progressively for subsequent 50 units. After 250 units, the billing will be ‘non-telescopic’, which means the slab rate will be applicable for the entire electricity consumed.[3] The following table shows the electricity tariff for domestic consumers

Tariff for Monthly Consumption (Upto 250 Units)[edit]

Consumption Slab Fixed Charges (Rs)  Electricity Tariff (Rs/Unit)
0-40 0 1.5
0-50 35 3.15

101-150 55 4.80
151-200 70 6.40
201-250 80 7.60

For Three phase customers having a monthly consumption up to 100 units, the fixed charges are set as Rs 90 and Rs 100 for up to 250 units.

Tariff for Monthly Consumption (Above 250 Units)[edit]

Consumption Slab Fixed Charges(Rs) Electricity Tariff(Rs/Unit)
