Sarawak Energy Berhad (SEB) is the Malaysian energy company based in Kuching, Sarawak. The company responsible for the generation, transmission and distribution of electricity for the state of Sarawak in Malaysia. It is wholly owned by the State Government of Sarawak.[2]

As of May 2016, Sarawak Energy had about 600,000 customers in the state.[3]


Sarawak Energy's history began in 1932, with the formation of "Sarawak Electricity Supply Company", by the Brooke Administration, to operate public electricity supply within Sarawak. Prior to that, in 1921 an Electrical Section within the Public Works Department was set up to look after the public electricity supply.[4]

In 1962, under the Sarawak Electricity Supply Corporation Ordinance 1962, the Sarawak Electricity Company was dissolved,and later created into a Corporation, known as Sarawak Electricity Supply Corporation (SESCO)[4] (Malay: Perbadanan Pembekalan Letrik Sarawak, and later Perbadanan Pembekalan Elektrik Sarawak or PPLS). In 1996, Sarawak Enterprise Corporation Berhad bought over 45% stake of the Corporation from the Sarawak Government.

In 2005, SESCO was privatised and known as Syarikat SESCO Berhad,[5] and bought over by Sarawak Energy Berhad.

In January 2016, Sarawak began to export electricity from Sarawak to West Kalimantan, Indonesia through a 275kV interconnection operated by Sarawak Energy.[6] This project is the first successful power trading project for Malaysia.[7]
