Sevan Hrazdan Cascade Hydropower System (the System) consists of seven run-of-the-river hydropower stations located along a waterway of connected rivers (Hrazdan and Marmarik, canals and reservoirs, principally fed by the Marmarik river. The System was originally built between 1930 and 1965. The Project involves the rehabilitation and modernization of the System's four hydropower plants, the diversion channels for three plants and associated electrical equipment replacement at the substations.

|Description||Sevan Hrazdan Cascade Hydropower System (the System) consists of seven run-of-the-river hydropower stations located along a waterway of connected rivers (Hrazdan and Marmarik, canals and reservoirs, principally fed by the Marmarik river. The System was originally built between 1930 and 1965. The Project involves the rehabilitation and modernization of the System's four hydropower plants, the diversion channels for three plants and associated electrical equipment replacement at the substations.|
|Objectives and Scope||The Project aims to restore part of the currently unavailable capacity of the System and increase its operational efficiency, reliability and safety. It aims to promote sustainable economic growth by enhancing reliability of electric supply. The Project will also reduce water leakage from the diversion channels and will contribute to more efficient use of water resources.|
|Status of Development Objectives||The development targets set at the approval stage are expected to be met in FY2018, including production targets of at least 600GWh of electricity in 2018 and contribution to government revenues. The Company's operation and maintenance are expected to be undertaken according to international good practice and safety standards from 2018 and the electricity generation and transmission equipment are expected to meet international technical, and environmental performance standards from 2018.|
|Status of Operation/Construction||As of 31 Dec 2017, the rehabilitation project is 95% complete and the remaining 5% are minor works expected to be fulfilled in 2018. Unit 1 and 2 of Yerevan -1 HPP, the last of the stations under rehabilitation, started operations in Nov 2017 and Aug 2017, respectively.|
|Linkage to Country/Regional Strategy||
The Project is consistent with ADB's Strategy 2020 in relation to environmentally sustainable growth, as one of the three strategic agenda items. Strategy 2020 emphasizes investment in infrastructure with further emphasis on promoting private sector participation. In addition, Strategy 2020 highlights ADB's operational emphasis on expanding the use of clean energy sources, reducing greenhouse gas emissions.
The Country Partnership Strategy (CPS) for Armenia is currently under preparation. The Project is expected to be consistent with the forthcoming CPS.
The Project remains fully consistent with the ADB Energy Policy 2009, under which support to renewable energy generation has been identified as a key priority. The policy further stresses the importance of harnessing energy efficiency which is essential to improve energy security and reduce emissions of greenhouse gases.
|Summary of Environmental and Social Aspects|
|Environmental Aspects||The main environmental impacts and risks from the System operations and proposed rehabilitation are related to reservoir management, management of oils and lubricants for turbines, transformers and support infrastructure, management of lead/acid batteries, material and waste management, and occupational and community health, safety and security. Some environmental impacts are expected from the proposed dredging of Yerevan 1 dam mainly on the biological environment downstream from Yerevan 1 dam due to increased turbidity. The negative socio-economic impacts are mostly related to construction works and transportation of equipment and materials including air emissions and noise, and are expected to be localized and short term.|
