Chashma Plant Sets Record with 400 Days of Operation

Pakistan has achieved a major milestone in its energy sector! The Chashma Nuclear Power Plant Unit-1 (C-1) has made history by running continuously for 400 days without interruption, setting a national record and placing itself among the top-performing nuclear plants in the world.

This achievement is being celebrated across the country, especially in the scientific and energy communities, as a sign of progress, stability, and self-reliance in Pakistan’s energy generation capabilities.

• Chashma Nuclear Power Plant Unit-1 operated non-stop for 400 days, setting a new national record

• The plant contributed consistent electricity to the national grid during this period

• Operated and maintained by Pakistan Atomic Energy Commission (PAEC)

• A major step toward clean and sustainable energy in line with the UN Sustainable Development Goals (SDGs)

• A symbol of Pakistan’s nuclear energy efficiency and technical expertise

This means the Chashma-1 unit worked without any shutdown, interruption, or maintenance break for over 13 months straight, supplying uninterrupted electricity to millions of homes, businesses, and industries.

• Top-tier safety protocols

• Regular maintenance schedules in previous years

• Highly trained local engineers and staff

• International standard operations and risk management

• Reliable Operation: The consistent power generation without even a single hiccup is a rare achievement, even for the most advanced nuclear nations.

• Clean Energy: Nuclear power produces zero carbon emissions during operation, making it eco-friendly.

• Cost-Efficient: Nuclear plants have low fuel costs and high energy output, especially when running without interruption.

• National Pride: It shows the world that Pakistan can independently operate and maintain complex nuclear technology.

Pakistan is working toward fulfilling SDG Goal 7: Affordable and Clean Energy. The 400-day performance directly supports this goal.

• No CO₂ emissions

• No air pollution

• Reduced pressure on fossil fuels

• Balanced energy mix

Several energy and policy experts have called this milestone a “game-changer” for Pakistan's nuclear energy reputation.

“This achievement not only strengthens our national grid but also proves that Pakistan is ready to expand its nuclear energy portfolio responsibly and efficiently.”
 Dr. Abdul Qadeer, Energy Analyst

PAEC deserves huge credit for maintaining such high operational standards at Chashma. Their engineers and scientists have been at the forefront of nuclear innovation in Pakistan.

• Ensure nuclear safety and security

• Maintain plant efficiency

• Train and equip local engineers with international expertise

• Collaborate with global partners like the International Atomic Energy Agency (IAEA)

PAEC has already announced plans to expand Pakistan’s nuclear energy production. New plants are being considered in:

• Karachi

• Muzaffargarh

• Chashma expansion (C-5)

If these projects succeed, Pakistan could generate over 8800 MW from nuclear power by 2030, reducing carbon emissions and helping meet climate goals.

The 400-day continuous operation of Chashma Nuclear Power Plant Unit-1 is not just a technical achievement — it’s a symbol of Pakistan’s progress, resilience, and self-sufficiency.

As Pakistan continues to expand its nuclear energy footprint, this success serves as a foundation of hope and pride for a brighter, cleaner energy future.
