Hydropower Plants

Laúca Main Works, Angola

In 2013, The Angolan Government has started the construction of the Laúca Hydropower Project with an installed capacity of 2,067 MW, presently one of the largest hydropower projects in Africa. As a member of an International Consortium, Lahmeyer was contracted for the design review and supervision of the dam, hydraulic power circuit and the powerhouse, including the electro-mechanical equipment. Lahmeyer will give assistance during commissioning and initial operation as also for the supervision during the first year of the warranty period.more


Capanda Hydropower Plant, Angola

The construction of the Capanda dam was initiated in 1982, but due to military conflicts the works stopped in the 1990s. After the resumption of the construction works the first units started going into operation in 2004. The power station contains four Francis Turbines with a capacity of 130 MW each. The dam is a roller compacted concrete (RCC) type with a maximum height of 110 m. more


Extension of the Pumped Storage Plant Vianden, Luxembourg

The pumped storage plant Vianden is situated in the area of Luxembourg's eastern border with Germany on the river Our and was commissioned in 1964. It was built as underground hydroelectric power station, consisting of 9 horizontal ternary power units. An additional power unit (pump turbine, "10th unit") was commissioned in 1976 in a separate shaft power station. Both plants are used to cover peak load demands.more


Hydropower Plant Masjed-e-Soleiman, Iran

Masjed-e-Soleiman is located in the province of Khuzestan in southwest Iran. The hydropower plant was initially planned and built with a rating of 1,000 MW, and was extended to 2,000 MW in a second phase. The rockfill dam has a clay core. The extension of the powerhouse cavern from 1,000 MW to 2,000 MW presented some very unusual challenges.more


Pumped Storage Plant Siah Bishe, Iran

The 1,000 MW pumped storage plant Siah Bishe is located some 125 km from Tehran. The power plant was planned and built mainly for coverage of peak demands from the city of Tehran (population 12 million). Studies of reliability led to the decision to construct 2 independent hydraulic systems.more


Pumped Storage Plant Koepchenwerk, Germany

The Koepchenwerk, designed by Lahmeyer and built between 1927 and 1930, is situated on the Hengstey reservoir on the river Ruhr. The plant was out of date and needed repair. Therefore, the generating sets were replaced by a new 150 MW pump turbine in a new shaft powerhouse including pressure tunnel.more
