In the 1920s.

This was the beginning of a century of growth and transformation into Malaysia’s largest renewable energy developer and primary provider of electricity to Sarawak and beyond.

Wholly owned by the Sarawak Government and under the purview of Sarawak’s Ministry of Utilities, today we are a vertically integrated power utility and employ over 5,400 Sarawakians serving almost three million people and over 700,000 domestic, commercial, industrial and export account holders.

Our vision is to achieve sustainable growth and prosperity for Sarawak by meeting the region’s need for reliable and renewable energy, setting the scene for us to build on our ambition in Southeast Asia.

We remain committed to our primary goal of providing Sarawak full access to 24-7 reliable electricity supply, and will continue to invest in our generation, transmission, distribution and digitalisation infrastructure to give Sarawakians a more modern electricity system and power Sarawak’s growth.

As we celebrate 100 years of powering Sarawak and move forward towards the next century of growth, we would like to say thank you to Sarawak and its people.
