Singapore Plans Massive Western Island Merger by 2050s for Industry and Power

Singapore will merge several western islands including Semakau, Bukom, and Pulau Sudong into one larger landmass over the coming decades, Prime Minister Lawrence Wong announced on August 23 at the 2026 National Day Rally. The new island will support advanced manufacturing, power generation infrastructure, and Singapore Armed Forces operations. The project echoes the creation of Jurong Island, which transformed Singapore’s economy as a global energy and chemicals hub over the past 50 years.

Why Singapore is merging its western islands

Singapore faces severe land constraints and must plan decades ahead to meet future industrial and energy needs. The new western island will support a new generation of industries beyond petrochemicals, including advanced manufacturing. It will also house power generation infrastructure to strengthen Singapore’s energy security amid global volatility and lack of natural resources.

Which islands will merge and what they currently do

Semakau houses Singapore’s only landfill. Bukom operates the country’s first refinery. Pulau Sudong has an airstrip used by the Singapore Armed Forces during emergencies. These three islands, plus a few smaller ones south of Jurong Island, will be combined through planned land reclamation over the coming decades. The merged island will preserve space for SAF operations and infrastructure.

How Jurong Island shaped the model

Jurong Island was created from the merger of several offshore islands through land reclamation and became a global energy and chemicals hub. According to PM Wong, this investment delivered lasting benefits: it created good jobs, anchored important industries, made Singapore a critical node in global energy flows, and strengthened energy security. PM Wong said the new western island can help shape Singapore for the next 50 years and beyond, just as Jurong Island shaped the economy for the past 50 years.

Second road link to Jurong Island and undersea tunnel to Tekong

The causeway linking the mainland to Jurong Island is heavily used, so a second road link will be built. A new link will also connect Jurong Island to the planned western island. Separately, Singapore is studying the feasibility of building undersea tunnels to connect Pulau Tekong to the mainland, which would replace current boat transport for military recruits and avoid cutting across busy shipping channels.

Final Thoughts

Singapore’s western island merger represents a bold long-term bet on industrial capacity and energy security. These projects will take decades to complete and require sustained investment, but they position Singapore to meet future economic and infrastructure needs as land becomes scarcer.
