Hydro Power Project-5th Extension (1410 MW) .......IBRD Credit of US$ 390 Million and AIIB US$ 300 million: The objective of the Project is to facilitate a sustainable expansion of Pakistan’s electricity generation capacity by installation of three additional power generating units having installed capacity of 470 MW each (total 1410MW) on existing Tunnel-5 without affecting the capacity for irrigation release. The total installed capacity of Tarbela Dam after completion of 5th Extension will rise to 6298 MW.

The total cost of the project is US$ 823.5 million. The World Bank (WB) will finance US$ 390.0 million and Asian Infrastructure Investment Bank (AIIB) will contribute US$ 300.0 million and the remaining US$ 133.5 million will be funded by funded by WAPDA (US$ 124.5 million) and National Transmission and Dispatch Company (NTDC) (US$ 9.0 million) for additional Transmission line from Tarbela to evacuate additional power.

The project would help in further development of Pakistan’s hydropower potential along the Indus River Cascade which is a cornerstone of the World Bank Strategy and Government’s energy policy to reduce load-shedding, reduce cost of electricity production, and improve financial sustainability of the power sector.

Tarbela-5th Extension Hydro Power Project would continue to support a number of community schemes initiated by WAPDA for communities of the area under Tarbela-4 Extension

World Bank ready to start Tarbela 5th extension project

Mar.13,2019





LAHORE: After riding on the success of Tarbela fourth extension hydroelectric power project, the World Bank and the Water and Power Development Authority (Wapda) foresee the completion of Tarbela fifth extension project by 2023.

After successful completion of the fourth extension project with capacity of 1,410 megawatts, the World Bank is moving forward to start the next phase of its renewable energy plan for Pakistan, namely the Tarbela fifth extension project.

The international lender is confident that the fifth extension project can be “put into operation in four years”, generating $200 million worth of additional revenue for Wapda per annum.

The World Bank recently concluded its Pakistan mission meeting, which was attended by the Wapda management, World Bank team leader Dr Rikard Liden and Adviser to the World Bank on Hydropower Masood Ahmad.

The World Bank team praised Wapda and other stakeholders, concluding that “the Tarbela fourth extension was one of the rare projects completed on time and below cost. It will add 3,000 gigawatt-hours (GWh) of electricity annually worth about $350 million and save foreign exchange”.


This is an important milestone as global statistics for hydroelectric power show an average of around 90% cost overrun and 70% delay in project duration.

The success of Tarbela fourth extension has also encouraged other international donors including the Asian Infrastructure Investment Bank (AIIB).

In its Annual Infrastructure Report for 2019, the AIIB reaffirmed its commitment

to the upcoming Tarbela fifth extension. Its Head of Communications said, “Our focus will remain on projects that can be carried out on a sound economic basis and contribute towards Pakistan’s long-term economic development.”


According to officials, the completion of Tarbela fifth extension will increase the capacity of overall Tarbela project from 4,888MW to 6,298MW, making it amongst the top 10 hydroelectric power stations in the world. It will also significantly enhance Wapda financial capability, allowing it to invest significant proceeds from Tarbela-4 and 5 in the expansion of Indus cascade.

Tarbela Dam is located on the Indus River 110 km from Islamabad in Swabi district and Haripur, Khyber-Pakhtunkhwa. The left bank irrigation tunnel, T-5, was constructed under the Tarbela dam project to provide a low-level outlet for additional irrigation supplies, when Tarbela reservoir is at a low level.

Best thing is, this is swing production. I.e u have it when u need it in summet

Dams are more important in solar era as they act as batteries

WAPDA Chairman visits Tarbela 5th Extension Project

Construction to Commence in July

May 11, 2021: In the wake of awarding the contract for civil works of the 1530 MW-Tarbela 5th Extension Hydropower Project (T5) last week, the Pakistan Water and Power Development Authority (WAPDA) Chairman Lt Gen Muzammil Hussain (Retd) today visited site of the project located at Tarbela Dam to review on ground the preparedness level for mobilization of the contractor to the site and start of construction work on the project, scheduled to be commenced in July this year.

During the visit, WAPDA Chairman had a detailed round of Tunnel N0. 5, sites of the Power House and Switch Yard and Intake of the Power House, therein, he was briefed about mobilization of the contractor and timelines for overall implementation of the project. WAPDA Member (Water) Abdul Zahir Khan Durrani, Member (Power) Jamil Akhtar, Authority’s Advisor Nasir Hanif, project management and representatives of the consultants were also there during the visit.

Speaking on the occasion, the Chairman said that T5 is yet another landmark project, being constructed by WAPDA under its least-cost energy generation plan to meet increasing demand of energy in the country through indigenous clean and green hydel electricity.

T5 is one of the 10 mega projects WAPDA is implementing to double the existing hydel generation with addition of more than 9000 MW to the National Grid in just eight years from year 2022 to 2028-29 in phased manner. The addition of this cheap electricity will help stabilize the power tariff by decreasing reliance on import of expensive fuel for thermal power generation, he added.

Underlining the importance of timely completion of the hydropower projects for national economy, WAPDA Chairman directed T5 project management to strictly adhere to the timelines set for completion of the project with no compromise on the stipulated standards of construction work.

It is worth mentioning here that T5 Project is being constructed on Tunnel No. 5 of Tarbela Dam with approved PC-I of US$ 807 million. World Bank is providing US$ 390 million, while Asian Infrastructure Investment Bank (AIIB) to the tune of US$ 300 million.

Continuous monetary assistance by the international financial institutions to WAPDA for construction of hydropower projects reflects their trust in WAPDA’s financial strength. Cumulative generation capacity of T5 Project stands at 1530 MW with three generating units of 510 MW each.

The project, scheduled to commence electricity generation by mid-2024, will provide 1.347 billion units of low-cost hydel electricity on the average per annum to the National Grid. Installed power generation capacity at Tarbela Dam will increase from 4888 MW to 6418 MW on completion of T5 Project,
