Pumped-Storage Hydroelectric Plants Elsewhere

Mingtan
Location: Taiwan
Operator: Taiwan Power Co
Configuration: 6 X 267 MW FPT
Operation: 1993-1995
T/G supplier: Voith, A-J
EPC: Sinotech
Quick facts: This was Taiwan's second PSP and the largest such plant in Asia at completion. The site is geologically complex and this made for difficult construction. Sun-Moon Lake, a notable recreation destination, serves as the upper reservoir of the scheme. From there, two waterways lead to an underground power house. For the lower reservoir, a 61.5m concrete gravity dam was built on the Shuili River. The 3.1km headrace conduits include steel-lined crossings of Tousheh River Valley. VA TECH won the contract for design, fabrication and installation of 26,000t of penstocks.

Palmiet
Location: South Africa
Operator: Eskom
Configuration: 2 X 203 MW FPT
Operation: 1988
T/G supplier: Voith, Fuji
EPC: Electrowatt
Quick facts: Palmiet is a joint venture between Eskom, which owns the power station and related facilities, and the Department of Water Affairs and Forestry (DWAF), which built, owns, and regulates the Palmiet dams. The power station generally operates on a weekly cycle and is part of an inter-catchment water transfer system that provides 25mn m of water annually to consumers in Cape Town, approximately 100km away. The lower Kogelberg Dam is on the Palmiet River and the upper Rockview Dam is between the Palmiet and Steenbras Rivers. A 2km tunnel connects to the powerhouse. Water for Cape Town flows from the Rockview Dam to the Steenbras Dam through a separate conduit. The plan is located in the scenic and ecologically sensitive Cape Fynbos Plant Kingdom, an area given international recognition as the Kogelberg Biosphere Reserve the first such reserve in South Africa.
