1 Hydro Engineering Company JSC "Hydro Engineering Company" abbreviated HEC, was founded in The primary target of the company business is development of hydro-epower recourses, rehabilitation of existing HPP s and the construction of new power plants. Theoretical capability of Georgia hydro electric power plants is 100 billion kw/h. However, in reality the country forecast power plants approximates to around 40 billion kw/h. That means that the country is only outputting at 25% efficiency currently on feasible capability. Due to objective reasons the existng HPPs are generating less electric power than is required by original design. Therefore, many stations requires modernization and rehabilitation workdue to this many programs have been created and the construction of new, electrical-power plants where considered. HEC works in cooporation with local and foreign companies. General information regarding the existing HESSEs in Georgia is given in the submitted prospectus along with the hydrotechnical characteristics and the list of perspective HPPs in Georgia, to be recommended for building in the first stage. h i d r o s a i n J i n r o k o m p a n i a samseneblo organizacia ss hidrosainjinro kompania, Semoklebulad hek, Seiqmna 2008 wels, kompaniis ert-ert ZiriTad mimartulebas (mizans) warmoadgens saqartvelos mdidari hidroenergetikuli resursebis atviseba, arsebuli amortizebuli hesebis reabilitaciisa da axali hidroeleqtrosadgurebis mseneblobis ganxorcieleba. qveynis saorientacio Teoriuli potenciali Seadgens 100 mlrd. kvt. st, xolo realurad ganxorcielebuli potenciali aremateba 40 mlrd. kvt. st. dremde dasaxelebuli potencialidan atvisebulia mxolod 25%, miuxedavad arsebuli simzlavreebisa, obieqturi mizezebis gamo, umravlesoba moqmedi hesebisa gamoimusavebs Tavis saproeqto SesaZleblobebTan SedarebiT gacilebit dabal eleqtroenergias. gamomdinare aqedan, mravali sadguri sawiroebs reabilitacias da modernizacias, ristvisac Seqmnilia specialuri programebi, amastan ertad ganixileba axali eleqtrosadgurebis mseneblobis SesaZleblobebi. arnisnuli programebis realizaciasi hek-s gansazrvruli aqvs mwidrod itanamsromlos adgilobriv da ucxour kompaniebtan warmodgenil prospeqtsi mocemulia saerto informacia saqartvelosi arsebuli hesebis Sesaxeb, mocemulia mati hidroteqnikuri monacemebi, aseve warmodgenilia saqartvelos im perspeqtiuli hesebis CamonaTvali, romelta ganxorcieleba rekomendirebulia pirvel etapze, saqartvelos energodamoukideblobis uzrunvelyofis miznit. 1
