Sarawak Energy

Sarawak Energy Berhad is the state owned electric utility company of the State of Sarawak. It is one of Malaysia's three electrical companies, the other two being Tenaga Nasional serving Peninsular Malaysia, and Sabah Electricity which serves the state of Sabah and territory of Labuan.

History
In 1921, an Electrical Section within the Public Works Department was set up to look after the public electricity supply. In 1932, "Sarawak Electricity Supply Company" was formed by the Brooke Administration to operate public electricity supply within Sarawak.

The Sarawak Electricity Company was dissolved in 1962, under the Sarawak Electricity Supply Corporation Ordinance 1962, and later created into a Corporation, known as Sarawak Electricity Supply Corporation (SESCO) (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, and bought over by Sarawak Energy Berhad.

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