Pakistan seeks bids for 960-MW Tarbela 4th Extension

Pakistan’s Private Power and Infrastructure Board (PPIB) invites proposals by June 13 for development of the 960-MW Tarbela 4th Extension project, adding another powerhouse to the 3,478-MW Tarbela hydroelectric project.

The proposal would add a powerhouse with two 480-MW turbine-generators, Units 15 and 16, to the right bank of the Indus River, utilizing discharge from the existing Tunnel 4 of Tarbela Dam.

The Tarbela project has five tunnels. Tunnel 1 has Units 1-4 of 175 MW each, while Tunnel 2 has Units 5-10 of 175 MW Each. Tunnel 3 has four units, 11-14, of 432 MW each, which were installed under the Tarbela 3rd Extension project.

While Tunnels 4 and 5 were designed exclusively for irrigation releases, a series of studies by TAMS, Harza International, Sir A. Gibbs, Chas. T. Main, and NESPAK concluded power generation at Tunnel 4 is technically and economically feasible without significantly affecting irrigation release capability.

With major civil works already in place, Tarbela 4th Extension would have a net head of 320 feet, penstock diameter of 36 feet, and annual energy production of 1,900 to 2,000 gigawatt-hours.

Selected developer to perform feasibility study

PPIB said private power developers would be pre-qualified and ranked based on their proposals. The highest-ranked party would be given a letter of interest for carrying out a bankable detailed feasibility study at its own cost. On completion of the feasibility study, the party would be eligible to develop and build the project.

Pre-qualification documents and ranking criteria may be obtained from the address below or from the Internet after payment of a registration fee of 6,000 rupees or US$100 and a document fee of 60,000 rupees or US$1,000 by demand draft or pay order to PPIB, payable on a bank branch in Islamabad. Payment also may be made by wire transfer, confirmed to PPIB by e-mail to feesubmit@ppib.gov.pk.
