Neelum Jhelum Hydropower Plant undergoes shutdown for inspection

The Neelum Jhelum Hydropower Plant, a significant power generation facility in Pakistan, was recently shut down for a physical inspection of its head race tunnel. This decision was prompted by a noticeable decrease in pressure within the tunnel that occurred a month prior. The plant, with a capacity of 969 MW, has been operating at reduced generation levels since early April to monitor the fluctuation in tunnel pressure.

On April 29, a further change in pressure led to the complete shutdown of the plant for inspection purposes. The management, in consultation with project consultants and international experts, is now working on a comprehensive plan to address and rectify the underlying issue. The inspection involves dewatering the 48 Km-long tunnel and conducting necessary remedial works to ensure the safety and efficiency of the plant.

The Neelum Jhelum Hydropower Project, situated in a geologically weak and seismic-prone area, features a vast underground tunnel system, with the head race tunnel spanning 48 Km and the tail race tunnel 3.5 Km in length. The project had previously undergone a shutdown in 2022 for repairs to the tail race tunnel, resuming electricity generation in August 2023 after completion of the necessary works.

The temporary shutdown of the Neelum Jhelum Hydropower Plant underscores the importance of regular maintenance and inspection in ensuring the safe and efficient operation of critical infrastructure. The proactive approach taken by the project management in addressing the tunnel pressure issue reflects a commitment to upholding safety standards and reliability in power generation.
