Electricity started in Sabah as early as 1910 supplied by 3 separate organisations. In 1957 these three organisations combined to form North Borneo Electricity Board. When North Borneo formed Malaysia with Federation of Malaya and the Sarawak in 1963 and changed its name to Sabah, this entity was renamed Sabah Electricity Board. On 1 September 1998 Sabah Electricity Board was privatised and became Sabah Electricity Sdn. Bhd.
The total generation capacity of SESB is 866.4 MW, 50.3% of the total units generated are purchased from the independent power producers (IPP).
The SESB installed capacity (excluding IPP) of the Sabah Grid which supplies electricity for major towns from Federal Territory Labuan to Tawau is 430.9 MW and the maximum demand is 760 MW (as of Jun 2010).
The East Coast Grid 132kV Transmission Line connecting the major towns in the East Coast has an installed capacity of 333.02MW and the maximum demand is 203.3MW.
The forecast demand growth of electricity is in a region of 7.7% per annum up to the year 2010 and the electricity demand is expected to reach 1,500 MW by the year 2020. To support the growing demand, various generation, transmission and distribution projects will be implemented.
A fully integrated grid connecting the West Coast Grid to the East Coast Grid was completed on 28 July 2007, and about 90% of the customers are now connected to this integrated grid.
