Mission Into The Future - A QuestFor SustainabilityLIVERPOOL, GREAT BRITAIN15 - 19 April 2013A VISIT TO A POWER PLANT:HEPP Lotru - CiungetPresentation made by the Romanian team:Teachers: Ioana Stancut and Monica CiuleiAnd students: Roxana Cocean and Damian Flori
How do we get electricity from water?Hydroelectric and coal-fired power plants produceelectricity in a similar way. In both cases a powersource is used to turn a propeller-like piece called aturbine, which then turns a metal shaft in an electricgenerator which is the motor that produceselectricity.A coal-fired power plant uses steam to turn theturbine blades; whereas a hydroelectric plant usesfalling water to turn the turbine. The results are thesame, but using water is a much CHEAPER and NON– POLLUTING way to produce electricity.
This is how ahydroelectric generatorlooks like.A hydraulic turbine converts the energy of flowing water into mechanicalenergy. A hydroelectric generator converts this mechanical energy intoelectricity.
A Visit to HEPP Lotru - Ciunget,Valcea CountyOn 31st of March 2013, 50 students and teachers from Magura School visitedHEPP Lotru - Ciunget, situated in a mountainous area of Valcea County.If you want to see the plant, you have to go 140 meters underground through a1200 meters long tunnel . It took six years to build it, between 1966 and 1972.The first hydro aggregate was put in use in November 1972.When talking about its power (510 MegaWatts), Ciunget is the third biggesthydroelectric power plant that was installed on the rivers from Romania. It isthe country’s second biggest plant , after Portile de Fier 1, when it comes to thehydro energy that is produced.In order to produce all this energy, HEPP Ciunget uses the water from VidraDam, the third man-made lake from Romania. The water from Vidra Dam isdirected through a 13.719 meters long network of underground tunnels. So thewater falls from 809 meters.

The generators and the turbines: the biggestpart of them is underground.Curiosity: the Pelton type turbines were builtin Resita, Romania, during the rule of dictatorNicolae Ceausescu and were used from 1972till 2009.Note: the photos were taken from the Internet, as we were notallowed to take any photographs outside or inside the plant.

Watching a film aboutHEPP CiungetDuring the visit, an engineer explained us how everything works, he showed us abig map with : Vidra Dam and Lake, 4 other additional dams (Galbenul, Petrimanu,Jidoaia, Balindru), 3 pumping stations and the 3 hydroelectric plants: Ciunget (510MW), Malaia (18 MW) and Bradisor (115 MW).We also watched a film about Ciunget : the beautiful area where it is located,thebuilding of the plant and what it means for Romania’s energetical system.
We visited the plantdivided in twogroups, so we have2 group pictures 31st March 2013, HEPPLotru – Ciunget
In 2009, Lotru-Ciungethydroelectric power plant was shutdown completely for re-technologization. Until that momentit produced 26 millions MW,summing-up over half a millionhours of functioning. The plant wasback in use in February 2011, after are-technologization process thatmeant investments of 88 millionseuros. The equipments of the hydroaggregates were modernized andthus the plant entered a new lifecycle that will last for another 30years.This is a photo from the official inauguration.
