Hydro Power

The hydro power plants are traditionally a well developed energy source in Bulgaria. The investment in such plants is quite attractive when carefully planned. 

Large hydro projects
 Among the most attractive projects to be carried out for several years are HPP Tsankov Stone "and" Lower Arda. By NEC have repeatedly stated willingness of the company to continue its major investment in these facilities.

9 small hydro power plants were built in Svoge and Mezdra 75 million euro with total installed capacity of all nine stations of the project is 25,6 mW

European Bank for Reconstruction and Development signed with HPP Svoge Ltd. Annex for 75 million euros contract to the refinancing of Phase 2 of the project: "Energy recovery waters of the Iskar River through the construction of nine small hydro power plants along the river in the territories of Municipalities Svoge and Mezdra. In 16-18 thousand megawatt clean energy per year will produce the first small plant near the Iskar River Mezdra - "Kaleto".

 According to experts in the Vratsa region has opportunities for the construction of hydropower plants on the rivers Iskar and Botunia. Currently in operation are three plants in Iskar - near Roman, Bruce and one of Mezdra Botunia in the land of Krivodol. Ministry of Environment and Water issued a water use permits for eight projects. It is envisaged that all 11 hydropower plants with total installed capacity of 30 megawatts per year on average to produce 150 million kWh of electricity. Designs for small power plants on the river near Botunia Krivodol and Misia and Malak Iskar near Roman.

At present in Bulgaria: 
- Wind power - 315.4 MB-  Solar installations - 3.9 MB- Small hydro - 43.84 MB

Work first hydro power plant in the upper valley of Arda.  HPP is located between the villages and Basket Mogilitsa under cave Uhlovitsa.

Plant will produce electricity from the waters of the Arda River and is currently the only plant in the region.  Construction of hydro took nearly two years. Investor facility is a French entrepreneur. Investor facility is a French entrepreneur. In north-eastern part of the highest Bulgarian mountains - Rila, about 80 km south of Sofia, stretches along the river "Kriva".  It is a tributary of the Maritsa and empties it in the western part of the Upper Field. River valley curve is characterized by its large inclination - in a distance of 10 km there is a natural drop 1300 meters. The energy of the river is the factor that makes this area one of the centers of the original iron in the Middle Ages in Bulgaria. As proof of this state remains open five Samokov, twenty "eminent" and over thirty blacksmith workshops. After the liberation of Bulgarian intellectuals assess the technical significance of this vast energy potential. Over 30 years of last century, our technicians perform the necessary hydraulic studies and suggestions for its use. 

  Cascade Belmeken - Sestrimo - Chaira is a unique object.

The most important facility of the cascade e Hydro Power Belmeken. It is built on a high plateau from which it originates and includes curve River Dam Belmeken, derivations of the first assembly zone, the Maritsa in 1900, "Potter" Dzhaferitsa and assembly derivations "Bistritsa", "Eli" and "monastery "in the valley of the Struma, PSPP Belmeken and Chaira PSHPP.Drop of water - 730 Maximum waterQuantity m3/sek 12.5 - T; m3/sek 6.86 - P
