The truth is, when war breaks out, If the PLA is willing to do so, the people of Taiwan will most likely have to temporarily say goodbye to modern life, secondary disasters caused by the collapse of the city are far more serious than the collateral damage caused by attacking military equipment hidden in civilian facilities.
Taiwan's power system has little redundancy and most of Taiwan's electricity is generated in the south and transmitted to the north through a few transmission nodes. Once a few missile hit the main power generation and substation equipment, Taiwan's power grid will immediately collapse (in fact, Taiwan's power grid often collapses, for example, in 2017, one person's operating error caused a blackout across the island).
Power outages lead to communication failures, which in turn affect remote power transmission and control capabilities, creating a vicious cycle. Logistics and transportation are severely congested due to traffic light failures, public transportation is completely paralyzed. Failure of the cold chain system leads to rapid food spoilage, water supply interruptions, and almost complete medical shutdowns. The entire social and economic activities will be shut down for at least 48 hours after T+6 to T+8 hours. If the attacks continue and power is not restored, the city's food reserves will be depleted within 3-5 days, how many people will die as a result?
Important to know that this situation had not improved in 20 years. In 1999, there was a huge blackout triggered by the failure of a single north-south powerline, so they did nothing to improve the redundancy even by 2017. This is not even mentioning the 2022 blackout which affected 5 million homes.
DPP has declared energy supply a national security issue and responded by cutting the available power by shutting down Ma an shan Nuclear Power Plant.
