Singapore’s installed solar photovoltaic (PV) capacity is forecast to grow to around 5.3 GW by 2035, up from nearly 1.6 GW in 2024. The projected expansion underscores the central role of solar energy as Singapore’s most viable domestic renewable option, given land constraints and the absence of indigenous energy resources.
The forecast indicates that solar PV capacity will grow at a compound annual growth rate of about 11.7 percent between 2024 and 2035, driven by continued deployment across rooftop, floating, and utility-scale projects. Policy support under the Singapore Green Plan 2030, which targets at least 2 GW of solar capacity by 2030, along with programmes such as SolarNova and financing and credit facilitation schemes, is expected to sustain investment momentum and expand adoption across residential, commercial, and industrial sectors.
Despite rapid solar growth, natural gas is projected to remain the backbone of Singapore’s power generation mix, accounting for roughly 94–95 percent of electricity output to ensure system reliability and flexibility. Gas-based capacity is expected to increase from about 10.4 GW in 2024 to nearly 14.8 GW by 2035, complemented by investments in energy storage, grid upgrades, and hydrogen-ready infrastructure. In parallel, Singapore plans to diversify supply through regional low-carbon electricity imports of up to 6 GW by 2035, positioning solar PV as the cornerstone of domestic renewable growth within a broader, security-focused energy strategy.
