Pumped-Storage Hydroelectric Plants Elsewhere
Location: South Africa
Operator: Eskom
Configuration: 4 X 333 MW FPT
Operation: 2016-2017
T/G supplier: Voith, Fuji
EPC: ARQ Consulting Engineers, Royal HaskoningDHV, Impregilo, CMC Ravenna
Quick facts: In Jan 2007, Eskom began full construction on the Ingula PSP after 20yrs of project development. Initially more that 90 sites were investigated for what was then called the Braamhoek project, and and three locations were short-listed. The final selection was a site near Ladysmith, 350km southeast of Joannesburg along the Little Drakensberg escarpment and straddling the provincial boundary of Free State and KwaZulu-Natal. The name change to Ingula was officially announced in Mar 2007 and in Sep 2009, Eskom awarded Voith Siemens Hydro a €140mn electro-mechanical equipmen contract. The upper and a lower dam are connected by 4.6km of tunnels passing through an underground powerhouse with four pump turbines. The main civil award was in Mar 2009. The project was originally scheduled to come on line during 2012, with a unit being commissioned each quarter, but in Jul 2009, the schedule was slipped a year and slipped more thereafter. Unit-4 went commercial on 10 Jun 2016. The project has the largest mudrock cavern in the world, totalling 200,000m³. As of Jun 2016, the total cost estimate was 25bn rand.

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 m³ 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 planT 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.

Location: Argentina
Operator: Empresa Provincial de Energia de Cordoba
Configuration: 4 X 175 MW FPT
Operation: 1986
T/G supplier: Allis Chalmers, Siemens
EPC: Agua y Energia, Panedile Argentina, Techint
Quick facts: This is the largest pumped-storage power station in Latin America. The complex includes over 20km of tunnels and a cavern with the T/G sets located 226m below the upper reservoir surface. Development started in 1970 when Agua y Energia began technical studies and the power station was inaugurated on 14 Feb 1986. It was transferred to EPEC in 2001.

Location: Iran
Operator: Iran Water and Power Resources Development Co
Configuration: 4 X 255 MW FPT
Operation: 2013-2014
T/G supplier: Voith Fuji, Siemens
EPC: Colenco, Poyry Energy, Lahmeyer International, WBI GmbH, Farab, Tablieh, Hadish Engineering, Kayson Construction
Quick facts: This is Iran's first PSP and started development around 1970. The site is in the Alborz Mountains in Mazandaran province, 125km north of Tehran. Complementary seismic studies and hazard analyses were carried out by Moshanir and Electricite de France and civil construction was started in the mid-1980s, but stopped in 1992 due to lack of hard currency. Moshanir completed a review of the project in 1999 and recommended completion; the project was retendered in Mar 2003. The site is designed to support a 1,000-MW second phase. The two pumped-storage reservoirs are 2.8km apart and two 2km headrace tunnels convey water 500m to the lower reservoir.The first unit was synchronized on 5 Dec 2013 and all four units were commissioned on 1 Sep 2015. The project cost about $333mn.
