Solar Energy Program

Background and Goals

1. To achieve the goal of nuclear-free homeland policy in 2025, the Taiwanese government plans to generate 20% of the nation’s power from renewable energy by 2025. Considering the geographic location and natural environment of Taiwan, solar and wind energy have been selected as the main sources of power generation.

2. TSC has assessed its land based on the consideration of geographic location, soil condition, ecological environment, and solar irradiance. Land that is fit for solar power generation will be selected to assist the government in reaching the goal of 20GW installed capacity by 2025.


1. TSC has assessed building roof-tops (including pig housing), non-arable land, defunct factory land ,forests with poor conditions and detention basin to set up roof-top or land based solar photovoltaic (PV) systems. The official purchasing procedures were conducted in a fair, just, and open manner.

2. Systems on roof-tops and in small area land have been set up and maintained by suppliers and leased to TSC thus increasing the speed of installation.

3. The capacity of the solar PV systems being installed in June 2023 has reached 512.12MW, including 14.93MW for roof-top, 99.95MW for water surface type, and 397.24MW for ground type.

Future Development

Continue to utilize TSC’s existing roof-tops (including pig housing), non-arable land, and defunct factory land for reaching TSC’s target of installed capacity to be 500MW for the period from 2021 to 2025.


Accumulated power generated by the solar PV system is expected to reach 622,110,000kWh in 2025. According to the electricity carbon emission factor (0.495kg CO2/kWh) publicized by the Bureau of Energy in 2022, the aforementioned energy generated by solar power will reduce 307,944 metric tons of CO2 emission.
