EcoLur

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 “Yeghegnadzor” and “Yeghegnadzor SHPP 1” SHPPs. “Yeghegnadzor” and “Yeghegnadzor SHPP 1” SHPPs are located in Vayots Dzor Region, in the administrative areas of Gladzor and Getap communities. The SHPPs are constructed on the Yeghegis River (length – 47 km). It’s operated by “MINA-MAYA” LLC.

The SHPP employees didn’t allow the expert group to visit the station, the examinations were carried out in thee water intake section.

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

· According to the project and the certificate issued by the Public Services Regulatory Committee on 1 October 2015, the estimated pressure of “Yeghegnadzor” SHPP is 51.24 m and “Yeghegnadzor SHPP 1” – 109.5 m. According to PSRC certificate, the estimated yield used by “Yeghegnadzor” SHPP is 4 m3/s and “Yeghegnadzor SHPP 1” – 1.2m3/s. According to the the PSRC certificate and the project, the projected capacity of “Yeghegnadzor” SHPP is 1620 kW and 1060 kW for “Yeghegnadzor SHPP 1”. According to the PSRC certificate, as of October 2015 the factual useful delivery of the electricity by “Yeghegnadzor” SHPP is 4.5030525 million kWh and 5.79 million kWh for “Yeghegnadzor SHPP 1”, the estimated production of “Yeghegnadzor SHPP 1” is 4.9 million kWh, duration of “Yeghegnadzor” SHPP license - 28.04.2010-28.04.2025, duration of “Yeghegnadzor SHPP 1” license - 28.09.2011-28.09.2026, the water usage permit is the same for both SHPPs. The construction water usage permit term is 20.09.2011- 20.01.2012.

·The water intake for “Yeghegnadzor” and “Yeghegnadzor SHPP 1” SHPPs are carried out from the same point through two pipelines. The length of the concrete dam is 19 m, its height is 1.6 m.

·There is a maze fish passway constructed on the left side of the dam – 1.5 m wide and 7 m long, and there was no water flowing at the moment of observation. The fish passway has 5 squares, each of which around 1.2 meters long.

·You can meet the following fish species in this section of the river: Kura barbell, Sevan khramulya (red-listed in Armenia), brown trout, Kura loach, the Prussian carp and rainbow trout.

·There is a garbage-collector installed with two-three-centimeter-long bars.

·According to the project, the length of “Yeghegnadzor” SHPP is 3250 * 54 meters, its diameter is 1.6*1.4 meters, the length of “Yeghegnadzor SHPP 1” is 2650 meters and its diameter is 1.2 m.

·Percentage correlation of aggregate length of SHPP derivation pipelines (24188 meters) of “Yeghegis 1” SHPP (the length of the derivation pipeline is 4000 meters, according to the certificate issued by the Public Services Regulatory Committee on 1 January 2015), “Yeghegnadzor” SHPP (according to the project, it’s length is 3250m, 54m), “Yeghegnadzor SHPP 1” SHPP (the length of the derivation pipeline is 2650 meters, according to the project), “Yeghegis 3” (the length of the derivation pipeline is 931.37 meters, according to the certificate issued by the Public Services Regulatory Committee on 1 January 2015), “Yeghegis 2” SHPP (the length of the derivation pipeline is 2138 meters, according to the project), “Yegheg” SHPP (the length of the derivation pipeline is 1924 meters, according to the project), “Goghtanik” SHPP (the length of the derivation pipeline is 1400 meters, according to the project), “Yeghegis” SHPP (the length of the derivation pipeline is 2450 meters), “Tigran Mets” SHPP (the length of the derivation pipeline is 2691 meters), “Khachi Qar” SHPP (the length of the derivation pipeline is 2240 meters) with the length of Yeghegis River makes up 51.46 %.

·The following SHPPs are planned to be constructed on the Yeghegis River: “Alnars” SHPP  - “Alnars” LLC developer (according to the PSRC certificate, the length of the pipeline is 2300 meters), “Yeghegnut” SHPP – “VTV Energy” developer (according to the PSRC certificate, the length of the pipeline is 2665 meters), “Elis” SHPP – “Elis HPP” LLC developer (according to the PSRC certificate,  the SHPP will be constructed on the Yeghegis and Soghanlu Rivers, the length of the pipelines is 2360,0 and 2288,0 meters),

·According to the water usage permit, “Yeghegnadzor” SHPP can take water in 10 months, it can’t take water in October and December, “Yeghegnadzor SHPP 1” can take water in all 12 months ensuring 0.870 cum/s environmental flow in the river. At the moment of observation, there was no environmental flow let out into the river.

·According to “Computation Center” CJSC data, in 2014 “Yeghegnadzor” SHPP operated for 10 months in 2014 and produced 3548824 kW electricity. The SHPP didn’t operate in July and August. In 2014 “Yeghegnadzor SHPP 1” operated for 12 months and produced 5370137 kW electricity.

·These SHPPs make use of the water amounts let out into the Yeghegis River through Arpa-Sevan tunnel.

·Automatic management and recording of water intake and environmental flow is not ensured.

·There is no water-meter sealed by a relevant environmental body in the water intake.

·The requirement of free water usage is not complied with.

·The nearby specially protected area of nature is “Yeghegnadzor” reserve, the location of which is the Yeghegis river basin of the right-bank tributary of the Arpa River in Vayots Dzor Region at 1200-2800 meters above sea level.

·No inspections have been carried out in the SHPPs.

Proposals

·To ensure automatic management of environmental flow in the head section, installation of water-measuring devices and online control.

·To calculate the real amount of the water flowing in the Yeghegis River taking into consideration the water amount let out into the Yeghegis River from the Kechut reservoir through Arpa-Sevan tunnel.
