Report summary

On 15 August 2017, Taiwan experienced a widespread power blackout. The majority of the country, nearly 7 million households, was affected. The blackout was caused by human error stopping gas supplies into the Tatan power plant. The plant, which has a total of 4,384 MW of gas-fired capacity, subsequently went offline completely and backup systems were insufficient to prevent power failures. Although power supply from Tatan was restored around five hours after it tripped, Taiwan is still facing tight power supply and its power system remains vulnerable.
