Malaysia and singapore to conduct full feasibility study for second power interconnection

The signing ceremony was held on the sidelines of the 43rdASEAN Ministers on Energy Meeting (AMEM) in Kuala Lumpur, Malaysia. The JDA was signed by TNB President/Chief Executive Officer, Datuk Ir. Megat Jalaluddin Megat Hassan; SP PowerGrid Chief Executive Officer, Jimmy Khoo; and SGEI Chief Executive Officer, Ong Teng Koon. Witnessing the signing ceremony were Malaysia's Deputy Prime Minister and Minister of Energy Transition and Water Transformation, Datuk Amar Fadillah Yusof, and Singapore's Minister-in-Charge of Energy and Science & Technology, Dr. Tan See Leng.

With the JDA, all three parties will commence a full feasibility study to ascertain the technical and commercial viability of the second interconnection. The study will build on the successful pre-feasibility study conducted by SP Group and TNB that was completed in May 2025, which established that there were no technical barriers in implementing a second interconnection.

"TNB, Malaysia's leading electricity utility, is committed to strengthening regional energy cooperation in support of the ASEAN Power Grid (APG). The upcoming feasibility study for the second Malaysia-Singapore interconnection is a crucial step towards expanding cross-border electricity trade. This initiative not only strengthens energy security but also supports Malaysia's National Energy Transition Roadmap by enabling greater integration of renewable energy," said Megat Jalaluddin.

"As Singapore's grid operator, SP Group remains committed to strengthening our power infrastructure to support regional grid connectivity. This study will be the conduit for closer collaboration with Malaysia to enhance energy security through diversified low carbon energy sources," said Chief Executive Officer of SP Group Stanley Huang.

"SGEI is pleased to partner with TNB and SP Group to conduct a full feasibility study for a second interconnection to strengthen energy connectivity between Singapore and Malaysia. This collaboration reflects our shared commitment to enable electricity trade and greater grid resilience between both countries," said Ong Teng Koon.

The JDA marks strong progress in the collaboration between Malaysia and Singapore to strengthen bilateral ties and regional power connectivity. The first interconnection between

the two countries was established in 1983 with the primary purpose of mutual support, and upgraded in 2022, accommodating bi-directional electricity flows to 1,000 MW. It currently supports two cross-border electricity trade projects - the Lao PDR-Thailand-Malaysia-Singapore Power Integration Project (LTMS-PIP) and the Energy Exchange Malaysia (ENEGEM) pilot project. The second interconnection will advance the APG vision by strengthening regional grid connectivity and greater cross-border electricity trade.
