Announcement on construction of Meghri HPP

An Agreement between the Government of the Republic of Armenia and the Government of the Islamic Republic of Iran on Cooperation in Construction and Operation of Run-of-River Power Plants on Araks River was signed in Meghri town of the Republic of Armenia on March 19, 2007.

The parties announce the opening of a tender for the selection of an investment company for implementation of the project on construction of Meghri HPP.

It is anticipated that the investor will independently solve all financial and organizational issues related to the construction, operation and management of the “Meghri HPP”.

The construction must be completed within 5 years, after which the electricity generated by the “Meghri HPP” for a warranty period of 15-20 years must be transported to Iran for sale by a 20-km long and 220-kV high-voltage double-circuit overhead power transmission line (providing 3 switchgear schemes at Agarak Substation) constructed by the investment company.

By April 5 of this year interested investors may submit preliminary proposals on the purchase price of electricity produced by “Meghri HPP” with a comprehensive outlined financial model to the Ministry of Energy Infrastructures and Natural Resources of Armenia to

In April of this year, a meeting-discussion is planned in Tehran, IRI. Participation of interested investors in the Tehran Meeting is preferable. During the Meeting, it is envisaged to give a preference to the potential investor, whose proposed financial model will be chosen as the best. Then the potential investor will be offered the conditions for further cooperation.


The main characteristics of Meghri HPP are listed below

- Design capacity_ 100 MW,
