About About Single Buyer

Single Buyer is the entity authorised by the Minister pursuant to the Electricity Supply Act (ESA) 1990 to conduct electricity planning and manage electricity procurement services for Peninsular Malaysia. Single Buyer plays a key role in promoting efficiency and facilitating competition in the generation sector, hence enhancing the development of the Malaysia Electricity Supply Industry (MESI).

Our main responsibility is to procure electricity from Independent Power Producers (IPPs) and TNB Generation to meet demand at least cost. SB plays an important role in planning and managing generator agreements to ensure supply to the electricity industry is secured, reliable and affordable. 

We prepare demand forecast reports and long-term capacity plant-up plans by optimising fuel type and resources to promote renewable energy to the system and ensure sustainability.

Through our knowledge and expertise in fuel availability and power contracts, we produce medium and short term capacity scheduling plans based on least cost dispatch methodology. SB also houses a technical advisory unit which provides independent advice on technical and industry related matters to related agencies as required.

Evolution of MESI

The Malaysian Electricity Supply Industry (MESI) has undergone several reforms to meet the industry objectives. The objectives are to deliver secure and reliable electricity supply at economically competitive tariffs whilst ensuring environmental sustainability and provides customer satisfaction through customer's choice.
