KUALA LUMPUR: Tenaga Nasional Bhd (TNB), SP Group and Singapore Energy Interconnections (SGEI) have signed a joint development agreement (JDA) to conduct a full feasibility study for a second electricity interconnection between Peninsular Malaysia and Singapore.

In a statement, TNB said the proposed interconnection, with a potential capacity of up to 2,000 megawatts (MW), aims to strengthen energy cooperation and expand cross-border electricity trade between both countries. Operations are targeted to begin by 2030.

Under the JDA, the three parties will commence a full feasibility study to assess the technical and commercial viability of the proposed second interconnection.

The study builds on a pre-feasibility assessment completed in May 2025 by SP Group and TNB, which confirmed there were no technical barriers to developing the additional link.

“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,” TNB president/chief executive officer, Datuk Ir. Megat Jalaluddin Megat Hassan said.

SP Group chief executive officer Stanley Huang said the company remains committed to strengthening Singapore’s 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,” he said.

Meanwhile, SGEI chief executive officer Ong Teng Koon said: “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.”
