In the framework of the project entitled “ Support to SHPP-relating Reforms Through the Dialogue of Public and RA Nature Protection Ministry for Sustainable Use of River Ecosystems” the expert group visited “Angeghakot” SHPP. “Angeghakot” SHPP is located in the administrative area of Angeghakot community, Syunik Region. The SHPP uses the drinking water of 'Jaghats' springs. It’s operated by “J&H HPP” LLC.
As a result of the monitoring, the expert group found out:
- The SHPP conducts water intake in the drainage basin constructed with concrete walls.
- According to the project, the static pressure of the SHPP is 110.0 meters, its calculated pressure is 86.7 meters, The estimated yield used by the SHPP is 0.2 m3/s, projected capacity is 150 kW, while the factual delivery of the electricity, according to Public Services Regulatory Committee's certificate, is 0.531645 kW/h, duration of license – from 02.03.2011 to 02.03.2026, water usage permit 08. 10.2012 - 08. 10.2015.
- According to the water usage permit data, the SHPP can annually take 3784.3 cum water.
- According to “Computation Center” CJSC data, in 2014 “Angeghakot” SHPP operated for 12 months and produced 49055 kW electricity.
- The amount of the environmental flow is not laid down in the water usage permit. The experts couldn't see any place for letting out environmental flow in the water intake section.
- The derivation pipeline is made of steel and runs over the surface. According to the project data, the length of the pipeline is 450 meters, its diameter is 30 mm.
- There is only one physically worn-out and self-made turbine installed in the station, the effectiveness of which is law. The station operates during the whole year.
- The transformer substation is fenced, there is only one transformer installed there, which is not equipped with an oil-collecting system.
- The area of the station is improved, it’s greened, but not fenced.
- There is no water-meter sealed by a relevant environmental body in the water intake.
- There is no automatic water management system in the water intake section.
Proposals
- To lay the derivation pipeline under the ground.
- To e-equip the SHPP building with a turbine having high technical effectiveness, which will result in the economic profitability of the SHPP.
- To ensure automatic water management system in the water intake section.
- To install a water-meter sealed by a relevant environmental body in the water intake.
- To improve the area of the station, to green it and to plant trees there.
- To equip the transformer with an oil-collecting system.
