Sabah Electricity Sdn Bhd targets to achieve 30pc reserve margin
Published on: Thursday, February 29, 2024
Madius said the significance of a bigger reserve margin lies in ensuring reliability during periods of high demand or unforeseen circumstances such as weather conditions leading to reduced renewable generation and unplanned outages of transmission and distribution lines or power plants.
Kota Kinabalu: Sabah Electricity Sdn Bhd (SESB) is targeting to achieve a 30 per cent reserve margin this year to give a more stable electricity supply to Sabah and the Federal Territory of Labuan.
SESB Chairman Datuk Seri Dr Wilfred Madius Tangau said to achieve this, SESB has devised comprehensive plans and initiatives as part of the company’s transformational strategy aligned with the Sabah Energy Roadmap 2040.

“These include projects such as Large Solar Scales (LSS) and biogas initiatives, aimed at bolstering our capacity and resilience in meeting the region’s energy demands.
Continuing our efforts to enhance the resilience of our power infrastructure, SESB has implemented various initiatives.
“One notable project is the installation of the Battery Energy Storage System (BESS) in Lahad Datu, a topic I previously discussed in one of my articles. This system, once completed, is poised to store a capacity of 100MW, anticipated to be operational by the end of this year,” he said.
He said SESB is also actively pursuing the installation of 100-megawatt (MW) diesel-powered generator sets on a rental basis as an interim measure to meet the energy requirements of Sabah and Labuan.

According to him, the calculation for the target does not encompass the electric generating sets expected to return to operation after repairs, with capacity estimated at 136MW.
Reserve margin is the available and usable electric capability that remains unused during peak load conditions in the electricity supply system.

For SESB, its electricity generation capacity for Wednesday (Feb 28) stood at 1,110MW while peak demand for power reached 1,064MW, giving a reserve margin of around 46MW or 4.3 per cent.
Madius said the significance of a bigger reserve margin lies in ensuring reliability during periods of high demand or unforeseen circumstances such as weather conditions leading to reduced renewable generation and unplanned outages of transmission and distribution lines or power plants.
“This will allow for scheduled maintenance of infrastructure without risking supply disruptions,” he said.
