Pakistan Requests Additional $300 Million from World Bank for Tarbela 5th Hydropower Project
Pakistan has formally requested an additional $300 million from the World Bank to cover cost escalation on the 1,410 MW Tarbela 5th Hydropower Project. The request is the second top-up under the existing Tarbela 4th Extension Hydropower Project loan, the parent facility through which the Bank is funding the broader Tarbela Dam expansion.
Pakistan has formally approached the World Bank for an additional $300 million (approximately Rs. 83 billion) to cover cost escalation on the 1,410 MW Tarbela 5th Hydropower Project, the country's latest effort to expand low-cost hydel generation on the Indus River. The request is the second tranche of additional financing sought under the Tarbela 4th Extension Hydropower Project — the existing parent facility through which the World Bank is channelling financial support for the broader Tarbela Dam expansion programme.
Background: The Tarbela Expansion Programme
Tarbela Dam, located in Khyber Pakhtunkhwa on the Indus River, is Pakistan's single largest hydroelectric facility and one of the biggest earth-filled dams in the world. The dam has been progressively expanded through successive numbered extensions, each adding new tunnels and turbines to extract more power from the same reservoir without requiring an entirely new dam structure.
The 5th Extension — commonly called Tarbela 5 — is designed to add 1,410 MW of installed capacity through an additional diversion tunnel. Once operational, it would represent one of the larger single additions to Pakistan's national grid in recent years and meaningfully increase the share of low-cost hydel electricity in the overall generation mix.
Why Additional Financing Is Needed
Cost escalation on large civil infrastructure projects is not unusual, and Pakistan's hydel programme has been no exception. Significant PKR devaluation over recent years raises the local-currency equivalent of any foreign-currency construction contracts. Global inflation in steel, cement, and specialised machinery, combined with extended project timelines, has pushed projected costs beyond the original approved budget.
Crucially, the $300 million Pakistan is requesting is structured as a second additional financing under the already-approved parent Tarbela 4th Extension loan — not an entirely new World Bank lending operation. This structure streamlines the approval process compared to initiating a fresh facility and reflects the Bank's continued commitment to the broader Tarbela expansion programme.
Significance for Pakistan's Power Sector
Pakistan's power sector is under sustained pressure from expensive thermal generation — particularly liquid-fuel plants and imported LNG — which inflates the fuel component of consumer electricity bills. Hydel power, by contrast, carries near-zero fuel cost once the civil infrastructure is in place, and its addition to the merit order reduces the Fuel Cost Adjustment (FCA) charge that NEPRA (the National Electric Power Regulatory Authority) passes on to consumers each month.
- Hydel units displace costlier thermal plants in NTDC's (National Transmission and Despatch Company's) merit order dispatch, lowering average per-unit generation cost system-wide.
- Lower generation costs flow through to the base tariff supplied to all DISCOs — LESCO, IESCO, MEPCO, PESCO, HESCO, QESCO, FESCO, TESCO, and GEPCO — and eventually to end-user bills.
- Securing World Bank financing also signals continued multilateral confidence in Pakistan's power infrastructure programme, a factor relevant to the broader circular debt reform agenda monitored under IMF programme conditions.
Frequently Asked
Questions about this story
What is the Tarbela 5th Hydropower Project and how much generation capacity will it add?
The Tarbela 5th Hydropower Project is an extension of Pakistan's Tarbela Dam in Khyber Pakhtunkhwa, designed to add 1,410 MW of installed hydel generation capacity through a new diversion tunnel in the existing dam structure. It is part of a long-running programme to maximise power output from the same Indus River reservoir.How much is the $300 million World Bank request worth in Pakistani rupees?
At current interbank exchange rates, $300 million is approximately Rs. 83 billion. This amount is required to bridge the gap between the original project budget and current projected costs driven by currency depreciation, global construction inflation, and extended timelines.Is Pakistan asking for a brand-new World Bank loan or additional money on an existing facility?
Pakistan is seeking additional financing — specifically the second top-up — on the existing Tarbela 4th Extension Hydropower Project loan, not an entirely new lending operation. This structure typically has a faster approval pathway at the World Bank than initiating a fresh programme.Will the Tarbela 5th Hydropower Project reduce electricity bills for Pakistani consumers?
Not immediately, but over time, yes. Once operational, the 1,410 MW of low-cost hydel power will displace costlier thermal plants in the national merit order, reducing the Fuel Cost Adjustment (FCA) that NEPRA passes on to consumers in their monthly bills across all DISCO areas.Does the World Bank financing for Tarbela 5 apply to K-Electric customers in Karachi?
The Tarbela 5th project feeds into the national grid managed by NTDC, which primarily supplies WAPDA-distribution DISCOs such as LESCO, IESCO, MEPCO, PESCO, FESCO, GEPCO, HESCO, QESCO, and TESCO. K-Electric operates its own separate network and generation mix, so direct benefits to Karachi consumers would depend on any future grid supply arrangements between K-Electric and NTDC.
