In Taiwan, due to different considerations such as the amount of consumption, storage hinterland, and storage methods, the safety stock of various imported energy sources varies. Among them, oil is 150 days, coal is 36 days, and natural gas is 7-10 days due to seasonal differences. If the future power generation method wants to move towards the road of increasing gas and reducing coal, then the current safety stock needs to be adjusted again. Thermal power remains high? Changes in electricity supply in Taiwan With the sound of sustainable development, can Taiwan's electricity supply move from fossil fuels to clean energy? Let's start with the way power has been supplied in the past.
According to the Bureau of Energy job email list of the Ministry of Economic Affairs, Taiwan's electricity supply in the past ten years has been dominated by thermal power generation, supplemented by nuclear power generation and renewable energy power generation, as well as pumped-storage power generation that is slightly higher than 1%. The annual power generation is here.Changes in total power generation in Taiwan over the past decade. Taiwan's annual power generation from 2012 to 2021 showed an upward trend, from 250.4 billion kWh to 290.9 billion kWh, an increase of 16.2%.
In terms of energy categories, thermal power generation was slightly lower than 200 billion kWh in 2012 and 2013, accounting for about 78%; after that, it increased year by year, and even increased by 15.7 billion kWh in 2017 compared with 2016; by last year, thermal power generation The volume has exceeded 240 billion degrees, a record high, accounting for more than 83% (Figure 2). It is worth noting that the proportion of thermal power generation reached the highest value of 85.9% in 2017, mainly due to the early decommissioning of some nuclear power units and political interference in that year, which caused the nuclear power generation to drop sharply compared with the previous year. 9.3 billion kWh, so it will increase thermal power generation to meet demand.
