Singapore aims to increase cumulative solar PV capacity to 4 GW by 2035, up from around 2.3 GW currently
To meet the target, it is exploring innovative ways to deploy solar, including solar carports, BIPV, and BAPV

From solar installations between buildings to panels on reservoirs and building façades, Singapore is exploring different ways to expand solar deployment despite its land constraints to meet the new target of 4 GW of cumulative solar PV capacity by 2035.
The country had initially set a target of 2 GW total solar capacity by 2030, which it achieved ahead of schedule. Its installed capacity currently stands at around 2.3 GW. During his Budget 2026 speech, Singapore’s Prime Minister and Minister for Finance Lawrence Wong raised the 2030 target to 3 GW (see Singapore Raises 2030 Solar Target To 3 GW After Hitting 2 GW Early).
Under its new five-year Energy Infrastructure Plan, the country now plans to further increase its ambition to 4 GW by 2035. The Energy Market Authority (EMA) says it will add more solar capacity to reservoirs, vacant land sites, and building rooftops across the island nation.
To meet this target, EMA has launched a Whole-of-Government Solar Demand Aggregation (DA) Framework. The idea is to aggregate solar demand across the public sector and accelerate deployment. It will explore innovative solar solutions such as solar carports, building-integrated PV (BIPV), and building-applied PV (BAPV) to make use of available space.
Additionally, the agency will collaborate with the Solar Energy Research Institute of Singapore (SERIS) to assess solar deployment opportunities across various surfaces, under a refreshed Solar PV Roadmap for Singapore.
To make it easier for homeowners to adopt solar, EMA has inked a memorandum of understanding (MoU) to develop a one-stop digital portal that can connect homeowners and installers as well.
The Energy Research Institute @ NTU (ERI@N) will collaborate with the EMA to map the capacity of local electricity networks to accommodate more solar in landed residential estates. This will ensure, explains EMA, that the grid can keep pace with growing solar adoption.
JTC Corporation, the government-owned industrial facilities developer, says it will pilot the country’s first overhang solar project in the Woodlands East industrial area. Under this configuration, solar panels are suspended in an overhang fashion across the void between two existing buildings. It has awarded the tender for the country’s maiden overhang solar project to EDP APAC. This will install at least 250 kW of solar capacity across unused spaces between buildings.
The project will cover an estimated 4,300 m² of space. It is expected to generate enough clean electricity to power around 60 four-room apartments annually over a 10-year period, exporting electricity to the national grid.
“With Singapore’s land constraints, we need to make the most of every opportunity to harness solar energy,” said EMA Chief Executive Puah Kok Keong. “Strong partnerships will be key to unlocking more opportunities for solar, making adoption easier, and ensuring that our grid is ready to support its growth.”
In parallel, Singapore will also increase its energy storage capacity to over 1 GWh by 2030, increasing from around 350 MWh at present. EMA says storage capacity is needed to strengthen system reliability and stability by responding to disruptions and balancing supply and demand fluctuations.
To meet growing electricity demand, mainly driven by energy-intensive sectors such as semiconductor manufacturing and data centers, it is seeking electricity imports from neighboring nations, including Malaysia and Indonesia. In August 2026, EMA conditionally approved 900 MW of clean power imports from solar and storage projects in Johor, Malaysia (see Singapore Approves 900 MW Clean Power Imports From Malaysia).
