Mingachevir Hydropower Upgrade Review

Our Role

SMEC was engaged to undertake an independent due diligence review of the proposed works to assist the Islamic Development Bank in its consideration of a loan to cover the electromechanical component of the project.

SMEC’s scope of work included:

  • Review of Azerenerji feasibility study
  • Site visits to inspect existing facilities
  • Determination of scope of proposed works
  • Preparation of independent cost estimate for the works
  • Identification of other issues which would impact on the proposed works

Project Overview

The Mingachevir Hydropower facility was constructed between 1946 and 1954. It comprised six 59.5 MW main power plant units, 3 high voltage substations (110, 220 and 330 kV) and a re-regulating dam (Varvara Dam) which incorporates a 3 x 5.5 MW power plant. Between 1999 and 2002, four units of the main power plant were refurbished and upgraded to 70.4 MW.

An indicative feasibility study for the rehabilitation and upgrade of the balance of the power plant was undertaken by the owner and operator, Azerenerji, Azerbaijan’s national electricity utility.

The proposed works include:

  • Replacement and upgrade to 70.4 MW of the remaining two units at Mingachevir
  • Refurbishment of auxiliary electricity supply
  • Refurbishment of penstocks and surge towers
  • Refurbishment of intake gates and dam piezometer network
  • Replacement of central control facilities, including new control room building
  • Replacement of all high-voltage substation switching equipment
  • Replacement and upgrade to 3 x 7.2 MW of the complete Varvara power plant
  • Extensive refurbishment of upstream and downstream works at Varvara Dam
