Wapda says hydropower generation crossed 6,000MW during peak hours

LAHORE: The Water and Power Development Authority said on Monday that its hydropower generation exceeded 6,000 megawatts on Sunday night after the Indus River System Authority increased water releases from reservoirs.

In a statement, Wapda said its hydel power stations supplied 6,118MW to the national grid during peak hours. The authority linked the rise in output to higher water indent by Irsa.

The statement said the Tarbela Hydel Power Station contributed 2,332MW, while the Tarbela 4th Extension Hydropower Project added 1,095MW. Ghazi Barotha generated 1,160MW and Mangla supplied 930MW to the grid.

According to the same breakdown, Warsak produced 135MW and Chashma generated 101MW. Wapda said the remaining 365MW came from its other medium and small hydel power stations.

Referring to the increase in water availability, the authority said:

With increased indent by Irsa, Wapda’s … hydel power stations provided 6,118MW to national grid during peak hours

Generation figures for 2025 and 2023-24

Wapda also shared broader generation data for its hydropower network. In 2025, its 22 hydel power stations generated 33.12 billion units of electricity. According to the authority, this accounted for about 30 per cent of the total electricity generated in the system.

The authority further said that during the 2023-24 fiscal year, its power stations collectively supplied 34.436 billion units of electricity to the national grid. This was 3.266 billion units higher than the output recorded in the previous fiscal year.

Installed hydel capacity

Separately, according to the Ministry of Water Resources, the total hydel generation capacity of Wapda’s hydropower projects stands at 9,459MW.

The figures released by Wapda provide a snapshot of hydropower output during peak demand hours as well as the contribution of its major and smaller stations to the national grid. The authority’s statement specifically identified Tarbela, Tarbela 4th Extension, Ghazi Barotha and Mangla as the largest contributors in the latest peak-hour generation tally, with additional output coming from Warsak, Chashma and other medium and small hydel facilities.

Wapda’s statement did not announce any new project or policy measure, but focused on the level of electricity supplied during Sunday night’s peak hours and the generation performance of its hydropower stations over the current year and the last fiscal year.
