Our Goals

Our goal is to introduce the highest international standards of quality management, environmental and occupational safety in a short period of time, to achieve high efficiency of water resources and production efficiency, at the same time ensuring the increase in electricity production.

Our values

Our values are aimed at incorporating the interests of various stakeholders in the field of our activity, and, as a result, effectively satisfying these common interests. The trust of our shareholders and partners is based on our responsible approach to the issues of high importance for the country.

International Power Corporation

International Power Corporation CJSC operates the assets of the Sevan-Hrazdan Cascade. The Company, registered in May 2003, was acquired in 2020 by "Hrazdan Energy Company (HrazJEK)" OJSC, which is part of the Tashir group of companies. This deal opened new prospects for the Company, taking into account the active participation of the Tashir group of companies in the energy system of Armenia, its experience of effective management of large strategic enterprises, human and financial potential.

The above factors create serious preconditions for the implementation of large-scale investment programs aimed at the necessary re-equipment of the assets of International Power Corporation CJSC in order to modernize the assets of the Cascade, improve the reliability and efficiency of electricity production. In this process the International Power Corporation CJSC will be guided by the highest international standards in the field of quality assurance, labor safety and environmental protection.

Historical production volumes

Sevan-Hrazdan Cascade

Sevan Hrazdan Irrigation-Energy Complex consists of a cascade of 7 hydroelectric power plants and 17 canals irrigating the Ararat Valley. The construction of the Cascade to utilize the energy potential of the water released from Lake Sevan for the irrigation of the Ararat Valley started in 1930 with the construction of the Kanaker HPP, the first hydraulic unit of which was put into operation in 1936. The construction lasted for 32 years, ending with the launch of the Yerevan-1 HPP. The Cascade hydropower plants use the waters of Sevan lake and tributaries of the Hrazdan River.

The Sevan-Hrazdan Cascade is the largest in Armenia with a total installed capacity of 561.4 MW. With this capacity, the annual production of electricity in 1957-1963 exceeded 2,000 GWh per year, and in 1993, during the energy crisis in Armenia, totalled to about 2,800 GWh. The energy of the Sevan Hrazdan Cascade satisfied about 90% of the Republic's demand by the end of 1950. Since 1978, the flow of water from Sevan lake for energy generation purposes had stopped to prevent further decrease of the level of the lake. Later, with the operation of the Arpa-Sevan tunnel in 1981, the level of Lake Seana began to rise, but since then the Sevan-Hrazdan Cascade derivation system operates with the priority of irrigation for agricultural needs.

The two HPPs of Sevan-Hrazdan Cascade, Sevan HPP and Hrazdan HPP, operate only with the energy of water released from Sevan lake during the irrigation seasons. The rest of the HPPs operate throughout the year, except for the smallest station, Yerevan-3 HPP, which operates during the non-irrigation seasons. The three HPPs of the Cascade: Kanaker HPP, Yerevan-1 and Yerevan-3 HPPs are located in Yerevan, the rest are located along the Hrazdan River between the Sevan lake and Yerevan.

The Cascade derivation system is 65.5 km long, of which 30.7 km are concrete open channels and 34.8 km are tunnels. Argel HPP, the third stage of the cascade, is the largest in Armenia with its installed capacity of 224 MW.

Sevan HPP is the only underground HPP in Armenia, and Arzni HPP is the only rock-cut HPP.

The Sevan-Hrazdan Cascade is essential for the whole energy system of Armenia. Given the age of the cascade equipment and the lack of large-scale full repairs, the power plants of the Cascade need thorough rehabilitation. The Tashir group of companies ahs set ambitious goals to undertake this task with the partnership of large international organizations.
