Taiwan is on course to install 31.2 GW of solar power capacity by 2035, according to projections released by UK-based consulting firm GlobalData, as the island accelerates its transition toward renewable energy following the phase-out of nuclear power.
GlobalData estimates that Taiwan will add around 1.1 GW of solar capacity this year, raising its cumulative installed solar capacity to 15.4 GW. Annual solar additions are expected to remain strong over the coming decade, ranging between 1 GW and 2 GW, enabling Taiwan to cross 20 GW by 2029 and exceed 30 GW by 2035.
The projected expansion is expected to reinforce solar energy’s position as Taiwan’s largest renewable power source. Total renewable power capacity in the country is forecast to increase significantly from 19.1 GW in 2024 to approximately 50.7 GW by 2035, with solar accounting for more than 61% of the total installed renewable capacity by that time.
According to GlobalData, Taiwan’s solar growth will be supported by a mix of rooftop solar programs, floating solar installations, and utility-scale solar projects, helping to diversify deployment pathways across limited land resources.
Taiwan completed its nuclear power phase-out in May this year, prompting a strategic shift toward expanding renewable energy generation alongside flexible gas-fired power capacity to compensate for lost baseload supply. GlobalData projects that gas-based generation capacity will increase from about 20.1 GW in 2024 to nearly 40.9 GW by 2035.
Mohammed Ziauddin, Power Analyst at GlobalData, said Taiwan’s energy policy focus has intensified on solar power, energy storage, offshore wind development, and grid infrastructure upgrades to ensure system reliability amid rising electricity demand from industry.
“Offshore wind and solar PV are reshaping Taiwan’s generation mix, while gas remains essential for maintaining reliability in an isolated and import-dependent power system,” Mohammed Ziauddin, Power Analyst at GlobalData said. “This balanced approach supports the island’s net-zero ambitions while ensuring power system resilience through 2035.”
