Outgoing 2025 proved to be a satisfactory year for the Hydropower and Water Sectors in Pakistan. WAPDA consistently contributed large quantities of clean, green, and low-cost hydel electricity to the National Grid and achieved several key targets on its under-construction mega Projects despite diverse and serious challenges.
In 2025, WAPDA’s 22 hydel power stations cumulatively generated 33.12 billion units, about 30 percent of the system’s total generation. WAPDA’s hydel electricity, with a tariff of just Rs. 3.83 per unit, continued to subsidise the country’s entire power sector this year too, thus significantly contributing towards economic stability and social development in Pakistan. Compared with the basket tariff, WAPDA’s hydel electricity is the most affordable energy in Pakistan. Besides, it is the most suitable source of energy, with zero carbon emissions during its generation, from the perspective of global climatic phenomena.
As per the details of WAPDA’s hydel generation in 2025, Tarbela Hydel Power Station contributed 14.3 billion units, while Tarbela 4th Extension 5.6 billion units, Ghazi Barotha Hydel Power Station 6.5 billion units, Mangla Hydel Power Station 3.6 billion units, Warsak Hydel Power Station 0.77 billion units and Chashma Hydel Power Station 0.79 billion units. Balance 1.56 billion units were generated by 3 High-Head Hydel Power Stations, Jinnah Hydel Power Station and other Small Hydel Power Stations.
In 2025, construction work on WAPDA’s eight under-construction projects, including Diamer Basha Dam, Mohmand Dam, Dasu, Tarbela 5th Extension, and the Greater Karachi Bulk Water Supply Scheme (K-IV), continued at a satisfactory pace. During the year, the Mohmand Dam Project achieved a major milestone, as filling of the Main Dam started in August. Likewise, the Diamer Basha Dam and the Dasu Hydropower Project are all set to place/pour roller-compacted concrete (RCC) on the main dams during 2026, as the pre-requisites are nearing completion on both Projects for this purpose.
It is worth mentioning that WAPDA’s under-construction Projects, upon completion, will add 9.7 million acre feet (MAF) to water storage and double the installed power generation capacity from 9,500 megawatt (MW) to about 20,000 MW. Besides, 560 million gallons per day (MGD) will also be made available for municipal use – 260 MGD for Karachi through K-IV Phase-I and 300 MGD for Peshawar through Mohmand Dam.
