Core Business Activities


Sarawak Energy is focused on the generation, transmission, distribution and retail of electricity. We generate power through hydro, coal and gas, capitalising on Sarawak’s abundant indigenous resources, and supply electricity to our customers throughout the state through an extensive network.


Blessed with high rainfall and an abundance of rivers, Sarawak harnesses renewable energy through hydropower development. Sarawak Energy’s first hydroelectric plant (HEP) at Batang Ai (108 MW) was commissioned in 1985, followed by Murum Hydroelectric Plant (944 MW) which was fully commissioned in the second quarter of 2015.

Sarawak Energy is pursuing the development of indigenous hydropower resources and has identified further sites as being highly promising for the construction of hydroelectric projects. 
In addition to large hydroelectric projects, Sarawak Energy has also identified potential small hydropower sites that support rural electrification in Sarawak’s many remote villages.
Sarawak Energy generates thermal power mainly through our coal and gas plants. Current installed capacity exceeds 1,200 MW, with five major power stations connected to the Sarawak State Grid and a number of standalone rural power stations.
The Bintulu Combined Cycle Plant, with a combined capacity of 317 MW, was registered with the United Nations under the Clean Development Management (CDM) scheme on 18 September 2010. The CDM scheme is part of the Kyoto Protocol environmental agreement and aims to encourage sustainable development and reduce greenhouse gas emissions. The Bintulu facility is the largest CDM plant in Malaysia.
Our latest development is the construction of the 2 x 300 MW Balingian Coal-Fired Power Plant located in Mukah. The project commenced construction in May 2014 and is expected to be completed in the first quarter of 2018 with first power generation by the end of 2017.
Grid System Operator
On behalf of the Regulator, Sarawak Energy is the Grid System Operator (GSO) which operates the Sarawak State Grid to meet the state’s future power requirements. This includes power generation scheduling and despatch.
Sarawak Energy is responsible for the maintenance and operation of the network to ensure reliable electricity supply throughout Sarawak. To strengthen reliability of supply, in addition to the existing 275 kV State Grid Transmission Lines, Sarawak Energy is constructing a 600 km second backbone 500 kV transmission lines.
Sarawak Energy operates and maintains an efficient distribution network to ensure reliable supply to our customers throughout the State. This includes overseeing data collection, providing policy and technical specifications, and undertaking maintenance and installation planning. To continuously improve the system operation of the distribution network and to reduce the duration of outages, Sarawak Energy has introduced various initiatives such as Condition-Based Monitoring, which uses advanced diagnostic equipment to monitor and detect abnormalities.
Our Retail arm serves more than 600,000 customers throughout the State. Our Customer Care Centre operates at two sites - Kuching and Miri - for 24 hours a day, seven days a week, to handle enquiries on technical and customer services. The system is equipped with state-of-the-art technology to handle the influx of calls especially during outages, has intelligent queuing call back feature, broadcast announcement and a monitoring system to keep track of the transactions for continuous improvement of our services.
We have also developed an extensive payment network for consumers, through partnerships with other utilities, banks, retail outlets and various other payment channels, so that nowadays our customers have literally hundreds of locations (and a number of online portals) where they can manage their accounts and make payments.
Our mobile application “SEB Cares” allows customers to monitor usage, report incidents and potentially pay bills.
Coal Resources
In 2015, Sarawak Energy was mandated to become an owner and developer, rather than merely a buyer, of Sarawak’s coal resources. Through our General Prospecting Licenses, we will be able to secure stable coal supplies for our operations and strengthen our ability to leverage on Sarawak’s indigenous coal resources.
