Taipower upgrades hydropower plant at Sun Moon Lake

Taipower upgrades hydropower plant at Sun Moon Lake

2026-03-19

Sun Moon Lake is not just a tourist destination, but a key pumped-storage hydropower reservoir. Taipower recently upgraded the system, including raising the dam of the downstream Minghu Reservoir to increase water capacity by nearly 1 million tons. It’s expected to generate an additional 222.3 million kilowatt hours of electricity annually, expanding the lake’s role as a “giant battery.”

Sun Moon Lake is renowned for its beautiful scenery, but it’s also a key pumped-storage hydropower reservoir. Taipower recently upgraded the system, raising the dam of the downstream Minghu Reservoir to increase its water capacity, and in turn increasing the amount of energy the system can store.

- Everything below here was all updated.
- All of it was changed?
- Everything was updated, even the operating facility was changed.

Taipower scaled up the system’s size and capacity. The water level in the reservoir’s dam was raised by 1.9 meters, increasing storage by nearly 1 million tons to bring the total capacity to 7.9 million. This is expected to generate over 200 million kilowatt hours more electricity annually, strengthening Sun Moon Lake’s role as a “giant battery.”

Hydropower plant deputy director
The project cost NT$240 million and took two years to complete. It increased reservoir capacity by 1 million tons and is expected to increase annual power generation by 222.3 million kWh. We are conducting high water level tests currently and expect to finish those in April.

After moving downstream and generating electricity, the water is stored in the downstream Minghu Reservoir. When power demand is low and supply is plentiful, it is pumped back up to Sun Moon Lake and can be used to generate electricity again when it flows back downstream later. This cycle lets the same water be used repeatedly, turning the system into a giant battery.

Teng Wen-kuei
Hydropower plant deputy director
When power supply faces peak demand and emergencies, Sun Moon Lake acts like a kind of relief pitcher, coming in for more innings to generate electricity and provide support.

With its expanded power capacity, Sun Moon Lake will be able to more effectively support Taiwan’s power supply.

日月潭抽蓄發電2.0版 "全台最大電池"戰力再升級

2026-03-19

日月潭不只是觀光湖泊,更是重要「抽蓄發電」水庫,近期台電還將抽蓄發電提升至「2.0版」,把下游明湖水庫壩體加高,增加近100萬噸水庫容量,預計每年供發電量可多222.3百萬度,擴充日月潭「大電池」戰力。

日月潭不只景色令人心曠神怡,更是重要的"抽蓄發電"水庫。近來台電還將抽蓄發電提升至2.0版,把下游明湖水庫壩體加高,蓄水容量加大,擴充水力發電量。

-連這裡底下全部更新
-全部都有改過?
-這邊全部更新,連那個操作設施都全部改過

加大、加量,台電將日月潭的抽蓄發電功能提升,下游明湖水庫壩體加高1.9公尺,增加近100萬噸水庫,滿水庫達790萬噸,預計每年發電量可多2百萬多度,擴充日月潭"大電池"的戰力。

“斥資2.4億元、耗時近2年完成,庫容增加100萬噸,預計增加年發電量是222.3百萬度發電量。目前正在製作相關高水位的測試,預計4月初會完成。”

發電後的水不會用完就流掉,而是先存在下游的明湖水庫,等待用電離峰、供電充裕時,再把水抽回日月潭,循環利用,達到"一滴水發N次電"的效益,成為全國最大"蓄能電池"。

[[大觀水力發電廠副廠長 鄧文貴]]
“未來供電面臨尖峰,以及突發狀態,身為"救援投手"的日月潭就能上場投更多的局數,來發電及救援。”

日月潭擴充抽蓄發電儲備能量後,更能有效配合穩定全台電力調度。
