WAPDA hydel output tops 6,100 MW on reservoir boost

ISLAMABAD:WAPDA hydel generation has surpassed the 6000 MW mark, reaching 6118 MW during peak hours after increased water releases by IRSA, offering cheaper electricity relief amid rising power burden on consumers across Pakistan as hydropower supports the national grid stability system.

The surge in hydel generation comes at a time when electricity consumers across Pakistan are already facing heavy financial pressure due to high tariffs, fuel cost adjustments, and capacity payments, making affordable hydel electricity a critical cushion for the national power mix.

According to official figures, Water and Power Development Authority (WAPDA) hydel power stations contributed 6118 MW to the National Grid during peak demand hours last night, reflecting improved water availability in major reservoirs following enhanced releases.

The increase in water flows was facilitated by the Indus River System Authority, enabling key hydropower stations to operate at higher efficiencies and inject low-cost electricity into the system at a time when thermal generation remains significantly expensive.

Station-wise data shows that Tarbela Hydel Power Station generated 2332 MW, followed by Tarbela 4th Extension with 1095 MW, Ghazi Barotha 1160 MW, Mangla 930 MW, Warsak 135 MW, and Chashma 101 MW, while the remaining 365 MW came from other medium and small hydel stations.

Industry sources said that hydel generation has remained the cheapest and cleanest source of electricity in Pakistan’s energy mix, helping reduce dependence on imported fuels and partially offsetting the cost burden that is ultimately passed on to end consumers through monthly electricity bills.

However, despite the temporary boost in hydel output, the broader power sector continues to face structural challenges, including rising demand, transmission constraints, and expensive thermal generation, which collectively keep electricity prices under pressure for households and industries alike.
