The Taiwan Power Company says that an annular solar eclipse that took place June 21 reduced the country’s solar energy output by 1.69 gigawatts. During the eclipse, the moon blocked out 99% of the sun in certain parts of Taiwan, while in other areas, the sun's visibility dipped by 95%.
The power company says that weather conditions were cloudy on the day of the eclipse, contributing to the drop in output. It says that solar energy output sat at around 1.73 gigawatts right before the eclipse began before dropping to a mere 42 megawatts during the peak of the eclipse.
The company says this gap is equivalent to twice the output of the Tunghsiao Power Plants -- Taiwan’s second largest gas-fired plants.
