Invitation for Expressions of Interest – PIU Consultant – Independent Engineer

Enguri HPP Rehabilitation Project – Phase IV

Project Description:  Engurhesi Ltd (the Borrower or the Company), the major hydro power generating company in Georgia, intends using the proceeds of a loan from the European Bank for Reconstruction and Development (EBRD) and grant money from the European Commission Neighbouring Investment Fund for the Enguri HPP Rehabilitation Project – Phase IV.

The project aims to make improvements to the 271m high arch dam and 9.5m diameter, 15km long pressure tunnel as well as related hydromechanical and electromechanical equipment, to alleviate significant leakages from the tunnel, ensure the long term safety of the tunnel, respond to heavy sedimentation problem in the reservoir and to enhance the environmental benefits of the Enguri and Vardnili Hydro Power Plants facilities.

The project generally aims at:

  1. increasing the availability of non-polluting renewable energy in the country; and
  2. improving operational safety of the Enguri power facility.


The Enguri HPP and the downstream Vardnili HPP Cascade were built during the 1960-70s as part of the same scheme.  Enguri HPP (5 units of 260MW capacity each) releases its water into the Vardnili HPP water channel, where four power plants were initially in operation.  Three of these plants were totally destroyed during the civil war in early 1990’s. The Enguri HPP itself suffered from lack of maintenance and until recently only four out of five units were operating at 80% of their capacity.

The EBRD has been involved in the rehabilitation of the Enguri Hydro Power Plant since 1998, initially with civil works on the dam, later with the rehabilitation of the units at the power plant. 

The Government of Georgia recently formally requested EBRD and the European Commission Neighbouring Investment Fund to consider the financing of the completion of the Enguri HPP rehabilitation programme - Phase IV. 

The proposed project, which has a total estimated cost of about EUR 35.0 Million equivalent, will require the procurement of the following goods, works and services:

  • Civil Works on headrace tunnel of 9.5m diameter and 15km long ;
  • Electromechanical works on Enguri Dam and switchyard;
