Singapore Targets 4 GW of Solar Capacity by 2035, Expands Innovative Deployment

Singapore plans to increase its cumulative solar capacity to 4 GW by 2035, up from approximately 2.3 GW currently, under its updated energy infrastructure plan.

To achieve the target, the Energy Market Authority (EMA) will explore new deployment options, including solar carports, building-integrated photovoltaics (BIPV) and building-applied photovoltaics (BAPV). Solar installations will also be expanded across reservoirs, vacant land and building rooftops.

The EMA has introduced a cross-government demand aggregation framework to combine public-sector solar demand and accelerate project deployment. It is also working with research institutions to identify new installation opportunities, improve grid readiness and develop a digital platform connecting property owners with solar installers.

A notable pilot project will bring Singapore's first overhead solar installation between buildings to the Woodlands East Industrial Estate. Developed by JTC Corporation and EDP APAC, the project will install at least 250 kWp of solar capacity across approximately 4,300 square meters of space between two existing buildings. The electricity generated will be supplied to the national grid.

Alongside solar expansion, Singapore aims to increase its energy storage capacity from around 350 MWh to more than 1 GWh by 2030 to improve grid stability and balance electricity supply and demand.

The country is also exploring clean electricity imports from neighboring countries to meet rising demand from data centers and semiconductor manufacturing. In August 2026, the EMA granted conditional approval for importing 900 MW of clean electricity from a solar-plus-storage project in Malaysia's Johor state.

With limited land resources, Singapore is increasingly turning to unconventional spaces, energy storage and regional electricity partnerships to support its clean energy transition.
