Dr Joachim witnessing the commissioning of the new 275kV Sabah–Sarawak Interconnection
KOTA KINABALU: The commissioning of the 275kV Sabah–Sarawak Interconnection marks a strategic milestone in strengthening electricity supply security and powering Sabah’s future.
Through this cross-border transmission link, Sabah is now able to tap into a wider and more robust generation mix from the regional grid, significantly enhancing system stability, increasing reserve margins, and supporting long-term demand growth.
The commissioning of the new 275kV Sabah–Sarawak Interconnection was witnessed by Deputy Chief Minister cum Works and Utilities Minister Datuk Seri Dr Joachim Gunsalam at the Load Despatch Centre near here today.
The commissioning ceremony, which marks a historic moment for both Sabah Electricity Sdn Bhd (Sabah Electricity) and Sarawak Energy Berhad (SEB), was attended by Sabah Electricity Chief Executive Officer Datuk Ir Ts Mohd Yaakob Jaafar and SEB Group Chief Executive Officer Datuk Sharbini Suhaili.
Also present at the event were Works and Utilities Ministry’s Permanent Secretary Datuk Ridwan Limus; Sabah Electricity Chairman Saadiah Aziz; and Energy Commission of Sabah (ECoS) Chief Executive Officer Datuk Ir. Abdul Nasser Abdul Wahid.
The synchronisation of the transmission line was carried out at PMU Mengalong, Sipitang, while the witnessing ceremony was conducted virtually via the Microsoft Teams platform, enabling seamless participation from both Sabah Electricity and SEB.
Meanwhile, Dr Joachim said the interconnection also reinforces the vision of creating a more resilient and interconnected Borneo power system, enabling energy-sharing capabilities, greater operational flexibility and enhanced protection against supply disruptions.
Ultimately, the project positions Sabah to accelerate its energy transition agenda, improve reliability for consumers, and foster sustainable economic development across the region, he said in a press statement.
The transmission lines were successfully placed on soak on 10 December 2025 and are scheduled to commence commercial operations on 13 December 2025, when energy flow will be connected to the Sabah Grid. This will allow an additional 30MW to 50MW of power to be injected, enhancing grid stability, supporting growing demand, and strengthening operational resilience.
This marks a new phase in Sabah’s energy transition and the advancement of initiatives that deliver better service and an enhanced experience for the people of Sabah.
Beyond Sabah, the interconnection also lays the foundation for the future ASEAN Power Grid.
