Monitoring Findings of

EcoLur

In the frames of "Supporting New Reforms in SHPP Sector through CSO-Government Dialogue" project, the expert group visited "Qurkik Jalal" SHPP, which is located in the administrative areas of Lermontovo and Antarashen Communities, Lori Region, Armenia. The SHPP is constructed on the Tandzut River, the length of which is 23 km. " Qurkik Jalal " SHPP is operated by "Qurkik Jalal" LLC. As a result of the monitoring, the expert group found out:

• "Qurkik Jalal " SHPP has been developed since 2007.
• According to the water usage permit, SHPP water intake coordinates are Х=44036'59.1'', Y=40045'02.3'', according to the water usage permit and Public Service Regulatory Committee, the mark of the upper canal pound is H=1841m (PSRC certificate dated on 1 April 2017). Water discharge coordinates are Х=44037'07.4'', Y=40045'53.8'', the mark of the lower canal pound is H=1748.0; according to the water usage permit and the Public Service Regulatory Committee.
• According to the project, the static pressure of the SHPP is 72.5m, while the project and PSRC say the estimated pressure is 62m. According to the project and the PSRC certificate, the estimated yield used by the SHPP is 0.89 m3/s. According to the project and the PSRC certificate, the projected capacity is 420 kW. According to the PSRC certificate issued on 1 April 2017, the factual useful delivery of the electricity is 0.559785888888889 million kWh, the estimated production of the SHPP is1.567 million kWh, duration of SHPP license - 28.12.2007- 28.12.2022, water usage permit - 05.12.2016-28.12.2022.
• According to the project, the SHPP dam is concrete. At the moment of visit, the concrete dam was replaced with a metallic one because of flooding. Dam length is 20m, its width is 6m.
• There is a stair-like fish passway made of metallic pipes in the SHPP head section 7.85 m long, 1.30 m wide and 2.90 m high. There are 9 stairs, each of which forms a small pond nearly 50 cm high and wide, where the height of water column makes up 25-30 cm. The height of the first stair of the fish passway is 35 cm. At the moment of observation, there was sufficient amount of water in the fish passway and the conditions were favourable for the movement of the fish to the upper reach. Nevertheless, during maximum or minimum water flows in seasons the stability and functional significance of this structure can't be thorough.
• There is garbage-collecting net 7.40 cm long and 1.67 m wide, and the distance between its bars is 3x3 cm.
• In the section of the river, where the SHPP is constructed, there are no red-listed fish species.
• The length of SHPP metallic pipeline is 3180m, while its diameter is 600mm, according to the project. Reclaiming has been carried out.
• The length of SHPP metallic pipeline is 1282m, according to the project and PSRC, while according to the company it's 1500 m. Its diameter is 700mm, according to the project and PSRC, while according to the company it's 700mm. Reclaiming has been carried out.
• There is a water-meter installed on the pipeline.
• The aggregate length of derivation of 'Qurkik Jalal' and 'Vahagni' SHPPs constructed on the Tandzut River makes up 76%(17482m) in the percentage relation with the river length (23km) (When calculating load the data on SHPP pipeline length in the PSRC certificate were taken into account).
• According to the water usage permit, "Qurkik Jalal" SHPP can carry out water intake of 11.148 million cum within 12 months from the Tandzut River ensuring the environmental flow of 0.04 cum/s. The project envisages environmental flow of 0.06 cum/s. According to "Qurkik Jalal" LLC, the maximum water amount used for the SHPP is 0.35 million cum, 50 liters per second.
• According to 'Computation Center' CJSC data, "Qurkik Jalal" SHPP operated for 7 months in 2016 producing 565993 kW electricity.
• Automated management of environmental flow is not ensured.
• There is no water-meter for the calculation of the environmental flow.
• There are two hydroaggregates of local 'Khorda' model installed in the SHPP building, the generator is synchronous. There is no automated management system.
• The transformer substation is fenced, there is one transformer installed, which is not equipped with oil-collecting system.
• The station area is improved and greened.
• The landscape is not disturbed.
• Requirements posed to fertile soil layer preservation and use are complied with.
• The SHPP has undergone environmental impact assessment.
• Requirements posed to for free water usage are ensured.
• There have been no inspections held at SHPP.
• The SHPP employs 8 people.
• The SHPP is located far from the residential area and the station noise doesn't disturb people.
• The SHPP doesn't implement social programs in the communities.
• According to 'Qurkik Jalal' LLC, the SHPP doesn't generate problems with drinking and irrigation water.

Proposals

1. If the concrete dam has collapsed because of floods (which is the result of incorrect estimates and incorrect design and construction), then the solution with metallic tins is a temporary and incomplete solution. It's proposed to construct a relevant water intake section in line with the standards with a dam and a fish passway.

2. To equip water-intake section with automated management, online supervision systems, and water-measuring devices, which will enable to regulate and control the water amount used by the SHPP and the amount of the set environmental flow. The water meter shall be sealed as prescribed.

3. 'Qurkik Jalal' SHPP produced 2 times as little electricity as the projected indicators and uses maximum 0.5 m3/s water amount instead of 0.89 m3/s water amount set in the water usage permit. It's proposed to review hydroeconomic estimates to add the amount of environmental flow set 40 l/s in the water usage permit (the project sets it 60 l/s).

4. To re-equip the SHPP with technically highly effective aggregates to ensure its projected capacity, which will have an entirely automated management system and will operate with less water amount.

5. To equip the transformers with an oil-collecting system.
