The average annual growth rate of electricity demand in Taiwan between 2026 and 2035 will reach 2.5%, 0.8 percentage points higher than previously projected. That came in the 2025 National Electricity Supply and Demand Report published by the Economic Ministry on Thursday, June 18.

The Ministry’s Energy Administration Director-General Wu Chih-wei (吳志偉) says the adjustment was caused by the expanding energy demand from AI data centers and the semiconductor industry as well as rising average temperatures, which is highly correlated with electricity demand for air conditioning.

To meet future demand, the ministry plans to add 26 gigawatts of natural gas-fired power generation capacity between 2026 and 2035, with 5.2 gigawatts expected to come online this year. It also plans to expand renewable energy generation. The ministry estimates that photovoltaic capacity will reach 31 gigawatts and offshore wind capacity 10 gigawatts by 2030, while by 2035 those renewable sources will generate 35 and 18 gigawatts respectively.
