SINGAPORE — Singapore is looking far beyond its current coastline, with plans to create a new western island that could eventually become a major hub for energy infrastructure, advanced manufacturing and other industries — while potentially keeping the door open to nuclear power.
Prime Minister Lawrence Wong announced during the 2026 National Day Rally that Singapore intends to merge several offshore islands south of Jurong Island, potentially including Semakau, Bukom and Pulau Sudong, through land reclamation over the coming decades.
The concept is similar to how Jurong Island was developed into a major energy and chemicals hub. The proposed western island could provide Singapore with additional land for industries that require substantial amounts of energy, including advanced manufacturing, semiconductor production and data centres.
But one aspect of the proposal is attracting particular attention: the possibility that the island could eventually accommodate nuclear power infrastructure.
Nuclear power is a possibility — not a decision
Experts cited by CNA said an offshore location could potentially make nuclear energy more practical for Singapore because of the country’s severe land constraints.
However, Singapore has not decided to adopt nuclear power.
The Government has been studying advanced nuclear technologies and developing the expertise needed to evaluate the option. Beginning in 2027, Singapore is scheduled to undergo the International Atomic Energy Agency’s Integrated Nuclear Infrastructure Review Phase 1 Mission, an international assessment designed to determine whether the country has the capabilities needed to make an informed decision about possible future nuclear-energy deployment.
The assessment does not mean Singapore has committed to constructing a nuclear plant.
Instead, officials have stressed that any eventual decision would have to consider factors including safety, reliability, affordability, environmental sustainability and energy security.
That distinction is crucial as speculation grows around the proposed western island.
Why build an island for energy?
Singapore currently depends heavily on imported natural gas for electricity generation. Government information says natural gas accounts for about 95 per cent of Singapore’s electricity generation, while solar power is constrained by the country’s limited land area.
The western island could therefore give Singapore something it has little of today: dedicated land for future energy infrastructure.
Experts told CNA that an offshore location could provide access to seawater for cooling and create greater physical separation between major energy facilities and residential areas.
Possible technologies could include conventional or hydrogen-ready gas generation, ammonia-based power generation and, depending on future decisions and technological developments, advanced nuclear systems.
But experts also cautioned that locating a nuclear facility offshore would not automatically make it safe. Safety would ultimately depend on the technology, engineering, regulatory framework and specific site conditions.
A potential “Jurong Island 2.0”
The proposed western island could become something of a “Jurong Island 2.0”, with its role potentially extending beyond traditional petrochemical activities.
Experts said the island could accommodate industries requiring large amounts of reliable electricity, such as:
- Semiconductor manufacturing
- Data centres
- Advanced manufacturing
- Chemicals
- Digital infrastructure
- Future energy facilities
Locating major electricity users close to power-generation and utility infrastructure could also reduce some transmission requirements and allow shared energy, water and other infrastructure to be developed together.
The proposal therefore goes beyond simply creating more land.
It could give Singapore greater flexibility in deciding how it powers its economy decades into the future.
Pulau Tekong could also get a major transformation
The western-island proposal is only part of Singapore’s longer-term land and infrastructure plans.
The Government is also studying the feasibility of an undersea tunnel linking Pulau Tekong to mainland Singapore.
Tekong currently has no land connection to the mainland, and military recruits travel there by boat for training. More reclamation is also planned in southern Tekong, creating additional space for Singapore Armed Forces training.
Around 500 hectares could eventually be available for future civilian use, although the Government has not decided how that land will be used.
Defence analysts said improved connectivity could allow Tekong to become a broader military training hub, potentially supporting more complex exercises and making logistics movements easier.
At the same time, greater accessibility could create additional security considerations, meaning appropriate safeguards would need to be built into any future connection.
The environmental question
The ambitious plans also come with environmental challenges.
Experts warned that large-scale land reclamation and the operation of power-generation facilities could affect marine ecosystems. Potential impacts include disruption to marine habitats, coral reefs and changes associated with thermal discharge from power plants.
This means Singapore’s future western expansion will involve more than engineering and economics. Environmental protection, energy security and long-term land-use planning will all have to be weighed together.
Singapore is planning for options, not announcing a nuclear plant
The biggest takeaway from the National Day Rally announcement is that Singapore is creating options for the future rather than committing to one specific energy technology.
The proposed western island could take decades to develop, giving Singapore time to assess how energy technologies evolve and what the country ultimately needs.
Nuclear power could be part of that future — but for now, it remains a possibility under study.
The more immediate significance of the plan is broader: Singapore is preparing additional land that could allow future generations to decide how the country powers its economy, supports energy-intensive industries and manages its limited physical space.
And as the proposed island takes shape, the question may no longer simply be how Singapore can find more land.
It could become a question of what Singapore chooses to put on that land — and how dramatically that decision could reshape the country’s energy future.
