The pumped storage power plant Dniester is located on the Dniester (Dnestr) in Ukraine and is under construction since 1,983th It is 8 km northeast of Sokyryany in the Chernivtsi Oblast . Presumably three of seven 324 MW generators are currently in operation (as of 2012). When it is completed, expected in 2017 [obsolete] , the power plant will have an installed capacity of 2268 MW.
background
The Dniester hydropower complex with a pumped storage power plant was planned in the 1970s, along with two dams (Dniester I & II) and a nuclear power plant. In 1983 Dnister II, a dam that dams the lower basin, was completed. Construction of the power plant began in 1988. Three years later, construction work stopped due to the dissolution of the Soviet Union . The project was restarted in 1993 and construction work resumed in 2001. The construction costs rose because the structures previously built had not been maintained. The first generator was put into operation on December 22nd, 2009. Commissioning of the second and third generators was scheduled for 2011 and 2012, respectively. Ukraine's difficulties in obtaining funding have been weighed down by controversies over transparency, environmental impact and water flow to the undercurrent to Moldova . Ukraine had asked for support from the World Bank , which in 2007 only provided US $ 29.6 million for the electrical transmission lines. Industry experts believe that Ukraine can complete the project independently. The hydroelectric power plant of the operator Ukrhydroenergo will probably go fully online in 2017.
Functionality and operation
The PSW works with reversible Francis turbines , which pump water from the lower storage basin into the upper one during periods of low electricity demand. The lower basin is dammed up by the Dniester HPP-II dam, which is 7.5 km to the southeast near the border with the Republic of Moldova . The lower basin has a storage space of 70 million m³. The upper basin with a storage space of 38.8 million m³ is formed by a ring dam. When there is a high demand for electricity, water is drained to the power plant to generate electricity. This changing process is used to adapt the power generation to the changing demand. The difference in height between the two reservoirs results in a hydraulic drop of 38.7 m.
While the seven Francis turbines and the generators provide 7 × 324 MW = 2268 MW in power plant operation, 2947 MW power is consumed when pumping with the same turbines.
Another, larger reservoir is dammed up by the Dnister dam HPP-I . It is 9 km north of the power plant. The HPP I barrier has its own hydropower plant with an installed capacity of 702 MW and a storage space of 3000 million m³. HPP-II has an installed capacity of 40.8 MW.
