“Paros” SHPP: Monitoring Results (Photos)


In the framework of the project entitled “Support to the Reforms of SHPPs through a Dialogue between the Public and The Ministry of Nature Protection of the RA for the Purpose of River Ecosystem Use” the expert group visited “Paros” SHPP. “Paros” SHPP is located in the administrative areas of Amasia Town and Bandivan Community, Shirak Region. The SHPP is constructed on the Akhuryan River (length – 186 km) next to “Arpi Litch” National Park. The SHPP is operated by “LightEco” LLC.

 As a result of the monitoring, the expert group found out:

  • The SHPP has been operating since 2012.
  •  At the moment of observation the SHPP was operating because of the problems with bank loaning.
  • There are certain incompliances between the real coordinates in water intake and discharge sections and the coordinates laid down in the water usage permit.
  • The constructed head section complied with the project solutions.
  •  According to the water usage data, the SHPP can take water from the river during 12 months ensuring environmental flow of 1.8 m3/s.
  •  According to “Computation Center” CJSC data, in 2014 “Paros” SHPP operated for 4 months - from May to August and produced 889470 kW electricity.
  • There is no fish-protecting structure in the SHPP head section, there is only a garbage collector, but 8-9-centimeter-long fish can get into the pipe through its wide bars.
  • The current structure and development of the fish passway make obstacles for the movement of the small fish species up the river.
  • You can meet the following fish species in the SHPP head section of the Akhuryan River - brown trout (Salmo fario) (met accidentally), the Sevan khramulya (Capoeta capoeta), the Kura nase (Chondrostoma cyri), the squalius (Squalius orientalis), Kura barbell (Barbus cyri), the South Caspian sprilin (Alburnoides eichwaldii), the Angora loach (Oxynօemacheilus angorae), the Kura loach (Oxynօemacheilus brandtii), the asp (Aspius aspius) (red-listed in Armenia), the Kura bleak (Alburnus filippii), the common carp (Cyprinus carpio), the Prussian carp (Carassius  gibelio) (climate-accustomed) and the stone moroko (Pseudorasbora parva) (climate-accustomed).
  • The diameter of the derivation pipeline is 2 meters, its length is 1740 meters, which comply with the project. Nevertheless, the pipeline is not metallic, as the project stipulates, but polymeric. It’s buried under the water.
  • Four local-produced turbines are installed in the station.
  • There is a fence and oil-collecting device in the turbine station.
  •  Free water usage requirement is complied with.
  • There is no landscape violations, no landslide signs.
  •  There is a biotoilet constructed.
  •  There is no water-meter sealed by a relevant environmental body in the water intake.
  • There is no automatic management system of the water level in the water intake.
  • The State Environmental Inspection hasn’t carried out any inspection within last two years.


The SHPP operation is not effective, as the water amount hasn’t been calculated correctly. There is a conflict between Akhuryan river water users. The water intake taken from the river for irrigation is not controlled and it’s not estimated how much water is left in the river after the irrigation for the SHPP operation and to preserve the environmental balance of the river.


1.To collect hydrological data and study them professionally taking into consideration water intake for the SHPP and irrigation.

2.To take measures to control irrigation system, if needed, to review water usage permit of the SHPP.

3.To install water-meter sealed by a relevant environmental body in the water intake. 

4.To introduce automatic management system of the water level in the water intake.

5.To construct a fish-protecting net till the pressure pipeline.

6.To make the fish passway compliant with the biological requirement and physical abilities of the fish living in the river.


The material was  developed in the frames of “Supporting reforms in the sector of small hydro power plants through enabling a dialogue between civil society  and the Ministry  of Nature Protection for sustainable use of river ecosystems” supported by UNDP/GEF Small Grants Programme".
