Malaysia – Power Sector

The Malaysian power sector is divided into 3 separate grids: Peninsular Malaysia, Sabah and Sarawak. Tenaga Nasional Berhad is the national utility company that dominates the National Grid in Peninsular Malaysia. In East Malaysia, Sabah Electricity Sdn Bhd (SESB) and Sarawak Energy Berhad control the state grids. These national and state-controlled utility companies monopolise all the transmission and distribution (T&D) assets within their respective grids.

Tenaga Nasional Berhad :-

Tenaga Nasional Berhad (TNB) was formed in 1990 by the Electricity Supply Successor Company Act 1990, to succeed the National Electricity Board (NEB) of the States of Malaya.

Tenaga Nasional Berhad (TNB) is the only electric utility company in Peninsular Malaysia and also the largest power company in Southeast Asia with MYR 99.03 billion worth of assets. It serves over 8.4 million customers  throughout Peninsular Malaysia and the eastern state of Sabah through Sabah Electricity Sdn Bhd. TNB's core activities are in the generation, transmission and distribution of electricity. Other activities include repairing, testing and maintaining power plants, providing engineering, procurement and construction services for power plants related products, assembling and manufacturing high voltage switchgears, coal mining and trading.

The TNB Group has a complete power supply system, including the National Grid which is energised at 132, 275 and 500 kilovolt (kV), with its tallest electricity pylon in Malaysia and Southeast Asia being the Kerinchi Pylon located near Menara Telekom, Kerinchi, Kuala Lumpur. The National Grid is linked via 132 kV HVAC and 300 kV HVDC interconnection to Thailand and 230 kV cables to Singapore.

The Generation division owns and operates thermal assets and hydroelectric generation schemes in Peninsular Malaysia and one Independent Power Producer (IPP) operating in Pakistan. In the peninsula, it has a generation capacity of 11,296 MW. Plans to expand its generation capacity include increasing hydroelectric generation  and commissioning the first nuclear power plant in Malaysia by 2025 if the government decides to include nuclear as an acceptable energy option.

Sabah Electricity :-

Sabah Electricity Sdn. Bhd. (SESB) is an electrical company that generates, transmits and distributes electricity mainly in Sabah and Federal Territory of Labuan. It supplies electrical power to 413,983 customers distributed over a wide area of 74,000 km2. 82.8% of the customers are domestic customers consuming only 28.8% of the power generated.

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. 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.

Sarawak Energy Berhad (SEB) :-

Sarawak Energy Berhad (SEB) is 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. As of May 2016, Sarawak Energy has about 600,000 customers in the state.

It has 36 power stations, a total installed capacity of 1315MW, comprising 5 per cent diesel engine, 25.6 per cent gas turbines, 36.5 per cent coal-fired power plant, 25 per cent Combined Cycle power station and 7.6 per cent hydro turbines throughout the state.  SESCO generates electricity mainly from two major types of plant; hydroelectric plants and thermal plants.

National Grid :-

National Grid, Malaysia is the high-voltage electric power transmission network in Peninsular Malaysia. It is operated and owned by Tenaga Nasional Berhad (TNB) by its Transmission Division. There are two other electrical grids in Sabah and Sarawak operated by Sabah Electricity Sdn Bhd (SESB) and Sarawak Energy Berhad (SEB) respectively. The system spans the whole of Peninsular Malaysia, transporting electricity in bulk from power generators owned by TNB and Independent Power Producers (IPPs) to distributors. The grid also transports directly to large industrial customers, such as steel mills and fertilizer plants.

Power generation capacity connected to the Malaysian National Grid is 22,858 megawatt, with a maximum demand of 17,788 megawatt as of April 2016. The generation fuel mix in peninsular is 45.55% gas, 50.23% coal, 3.59% hydro and 0.63% from other forms of fuel.
