[Reporter Lin Jinghua/Taipei Report] The exposure of the nine frogs at Sun Moon Lake drew the attention of the outside world to the water situation. Taipower stated that the stacked images of the nine frogs are for reference only. At present, there is still 70% of the water in the Sun Moon Lake Reservoir. Taipower will cooperate with the Water Resources Department to properly plan and dispatch water resources , At the same time, prudently plan the hydropower generation in spring, and give priority to the use at night and in summer. In addition, the maintenance units will return to join the power supply one after another, so as to ensure the stable and safe power supply in the future.

According to Taipower, the water level of Sun Moon Lake Reservoir was about 743.89 meters on the morning of the 4th, and the water storage capacity was 72.1%. The height of the ninth Nine Frogs was 745.9 meters.

Taipower said that in response to the continuous development of renewable energy, solar photovoltaics have increased significantly during the day, and the pumped-storage hydropower units of the Daguan No. 2 Plant in Sun Moon Lake and the Mingtan Power Plant have also cooperated with the transformation to support the electricity demand during peak hours at night. The operation mode has been changed to 2 pumps and 2 generators. According to the amount of water stored in the two reservoirs of Minghu Xiachiba and Mingtan Xiachiba, the abundant sunlight is used to pump water back to Sun Moon Lake Reservoir during the day, and the water is released to generate electricity at night according to the electricity demand. Therefore, the water level of Nine Frogs is at Both morning and evening vary with power generation.

Taipower pointed out that the water level of Sun Moon Lake will rise and fall according to the water level of the lower pools of Guaner and Mingtan pumped storage power plants. In the past, the water level of the lower pools of the pumped storage power plants dropped to the lowest around 8:00 am, and the water level of Sun Moon Lake rose. During the night peak electricity demand, the pumped storage power plant continues to operate in the pumping mode during the daytime until about 3 pm, so the water level of Sun Moon Lake will be slightly lower at 8 am and the highest around 3 pm.

Taipower said that the amount of water in the upper reaches of Sun Moon Lake is low due to the low rainfall in winter, and the water supply will still be adjusted in accordance with the downstream agricultural water use. It is hoped that the spring rains and plum rains in April and May will bring the water level of Sun Moon Lake back to normal.

Taipower emphasized that it will carefully dispatch hydraulic units to meet people's livelihood and irrigation needs, supply water and generate electricity at the same time, maximize the benefits of water resources and not waste it, and continue to cooperate with the Water Resources Department to conservatively respond to future changes in water conditions.
