Taiwan on track to replace nuclear energy with solar and wind by 2025, but country still heavily reliant on thermal power, says GlobalData

Taiwan’s nuclear power installed capacity decreased from 4.9GW to 3.8GW, at a compound annual growth rate (CAGR) of -1.2%, according to leading data and analytics company GlobalData. If this trend continues, the country is set to meet the government’s target of zero capacity by 2025. Taiwan intends to fill the gap created by the retirement of its nuclear power plants with renewable power capacity, which is targeted at 27GW of installed capacity by 2025.

Rohit Ravetkar, Power Analyst at GlobalData, says: “Renewable power capacity in Taiwan is estimated to increase to 40.6GW in 2030 from 7.4GW in 2020, at a CAGR of 18.6%, a significant jump for a country that relies mostly on coal for electricity generation. The government has been actively encouraging the use of renewable sources for energy generation to reduce dependence on fossil fuels. Solar PV and offshore wind will be the most installed renewable technologies in the country by the forecast date. Onshore wind capacity will grow but will be limited by the availability of land area. This has prompted the government to announce the start of the development of offshore wind power. Since Taiwan is an island nation, it has substantial potential to harness power from offshore wind plants. Moreover, with the government focusing on rooftop PV installations to meet its 2025 target of 20GW of solar PV capacity, the renewable energy market will witness strong growth in coming years.”

Ravetkar continues: “Taiwan is heavily dependent on thermal power, which itself is dependent on imported coal and gas. The share of generation from thermal power increased from 75% in 2000 to 83% in 2020. Taiwan has been one of the highest coal and gas importers in the world, and such high level of import reliance is a challenge for the country’s energy security. The solution is to engage more in storage systems. The power generation from coal power plants is speculated to decline in the coming years due to the government’s plan of gradual phase out of coal power plants.”
