Hydropower in Armenia
Armenia`s hydropower potential is provided by 200 rivers and streams which together can provide a potential of 21,8 bln. KWh. The main two hydropower sources are Vorotan and Sevan-Hrazdan cascades, which together provide 17% of the country`s electricity. 13% of RA`s energy generation is covered by 178 SHPPs, the number of which is projected to increase during the following years with the realization of several hydro projects.

Hystory
Historically hydropower was one of the greatest sources of the electricity production in RA. The first hydropower station had been founded in 1903. With its construction, it enabled to start copper production in Syunik. Till the 1910s, there were 9 SHPPs operating in the Republic of Armenia. The total power capacity of these plants was 2155KW and the actual annual electricity production in 1913 was 5,1 million KWh. In the 1920s the construction tendency of the hydropower plants started to grow. First examples became two HPPs constructed in Erevan and Gyumri`s HPP. Later, in 1927, Dzoraget Hydroelectric Power Station construction started, which began its operation in 1932. In the early 1990s, there were 28 Small hydropower plants operating. Starting from the 2000s, Armenian government undertook the construction of new SHPPs. In 2010, the number of SHPPs operating in the country reached to more than 80 thus providing about 5% of the total energy production of Armenia.

Armenia water resources
Armenia has more than 200 rivers and streams flowing inside its territory. Most of them have a length of more than 10000km. The biggest rivers are Araks, Hrazdan and Debed. Armenia`s hydropower potential is 21,8 bln. KWh, from which more than 85% comes from big and middle rivers. Only 15% of the energy potential comes from small rivers or streams.

Armenia Big Hydropower plants
There are two big hydropower cascades in Armenia, Vorotan and Sevan-Hrazdan. Sevan-Hrazdan cascade includes 7 HPPs with the total capacity of 565 MW, which supplies about 10% of the country`s electricity consumption. The annual electricity generation is 2.32 bln. KWh. Vorotan cascade is a combination of three stations. With the total energy capacity of 404 MW (7% of the total supply), it is the second largest hydroelectric power plant in Armenia. The annual electricity production is about 1,16bln.'' KWh. ,

Armenia SHPPs and further development
According to the data of January 1, 2017, 178 Small Hydropower Plants were in operation with the total electricity generation capacity of 328 MW, in case of average 880 million actual energy supply. In 2016, SHPPs provided about 13% of Armenia`s energy generation. According to the projections (January 1, 2017), 74 MW capacity will be added to the total energy potential of Armenia`s SHPPs during the following years with the construction of 39 additional SHPPs which will increase total annual electricity supply by 260KWh. A recent memorandum (10/30/2017) signed between the Ministry of Energy Infrastructures and Natural Resources of the RA and the US Ambassador in Armenia implies the realization of the hydro project Shnogh, which will increase the energy capacity of RA by 76 MW. Besides Shnogh, there are 2 other middle-sized HPP construction plans. The Meghri HPP with the capacity of 100MW and annual energy generation of 800 million kWh will be constructed on Araks river. Loriberd HPP will be constructed on Dzoraget River and will have a capacity of 66MW with annual electricity generation of about 200 million KWh.
