Pakistan is rapidly advancing its nuclear energy capabilities with the Chashma-5 (C-5) nuclear power plant, a project that has recently secured vital international clearances and reached significant construction milestones. As the country seeks to diversify its energy mix and reduce its reliance on volatile fossil fuel imports, the C-5 unit stands as a cornerstone of Pakistan’s long-term strategic energy plan.
In a landmark development in March 2026, the International Atomic Energy Agency (IAEA) Board of Governors unanimously approved the Safeguards Agreement for Chashma Unit 5. This approval is a major diplomatic and technical win for Pakistan, reflecting global confidence in the nation’s commitment to the peaceful use of nuclear energy and its adherence to international non-proliferation standards.
Construction Progress and 2030 Completion Goal
The formal construction of the Chashma-5 project began with the first concrete pour on December 30, 2024, following the issuance of a construction license by the Pakistan Nuclear Regulatory Authority (PNRA). This milestone transitioned the project from the planning and site preparation phase into active development.
Located at the Chashma Nuclear Power Complex in Punjab, the plant is expected to be completed and operational by 2030. Once online, the facility will add 1,200 MW of clean, safe, and low-cost electricity to the national grid. This addition will bring Pakistan’s total nuclear energy capacity to approximately 4,760 MW, significantly boosting the role of carbon-free baseload power in the country.
Technical Excellence: The Hualong One Design
Chashma-5 utilizes the advanced Chinese Hualong One (HPR1000) design, a third-generation pressurized water reactor (PWR). This technology is renowned for its sophisticated safety protocols, which include both active and passive safety systems. Key features of the HPR1000 design include:
- Double-Shell Containment: A reinforced structure designed to withstand external impacts and prevent radiation leakage.
- Reactor-Filtered Venting System: An advanced mechanism to manage internal pressure during emergency scenarios.
- 60-Year Operational Lifespan: Providing decades of stable power generation for the national economy.
This project follows the successful deployment of the same technology at the Karachi Nuclear Power Plant Units 2 and 3 (KANUPP-2 and KANUPP-3), which are already contributing thousands of megawatts to the coastal region.

Economic Impact and Strategic Financing
The Chashma-5 project represents a massive investment in Pakistan’s infrastructure, with a total estimated cost of $4.8 billion. The financing structure is a testament to the “All-Weather Strategic Cooperative Partnership” between Pakistan and China.
| Key Project Metric | Value/Detail |
|---|---|
| Total Estimated Cost | $4.8 Billion |
| Chinese Funding Contribution | 85% (CNNC) |
| Generation Capacity | 1,200 MW |
| Projected Job Creation | 40,000 Direct/Indirect Jobs |
| Target Completion Date | 2030 |
| Proposed Energy Tariff | Rs16.7354 per unit |
In January 2025, the Pakistan Atomic Energy Commission (PAEC) submitted a formal petition to the National Electric Power Regulatory Authority (NEPRA) for a levelized tariff of Rs16.7354 per unit (approximately 5.97 cents). This tariff is designed to remain stable over the plant’s 40-year commercial life, offering a hedge against the price volatility associated with imported coal and liquefied natural gas (LNG).
Socio-Economic Benefits and Job Creation
Beyond the immediate energy output, the C-5 project is a major driver of socio-economic development. During its peak construction phase, the project is anticipated to create up to 40,000 jobs, including roles for engineers, technicians, and manual laborers. This influx of technical work helps develop a highly skilled local workforce, fostering industrial growth in the surrounding regions.
The shift toward nuclear energy is also saving Pakistan billions in foreign exchange reserves that would otherwise be spent on fuel imports. In 2025, nuclear power accounted for 18.3% of the national electricity mix, and the addition of C-5 is a critical step toward the government’s ultimate goal of reaching 8,000 MW of nuclear capacity.
International Confidence and Energy Security
The unanimous approval of the safeguards agreement by the IAEA Board in March 2026 underscores the transparency and safety of Pakistan’s nuclear program. Foreign Office officials have noted that this agreement reflects the international community’s trust in Pakistan’s regulatory frameworks and technical expertise.
As Pakistan faces the dual challenges of climate change and energy security, the Chashma-5 nuclear plant provides a sustainable path forward. By delivering a massive injection of low-carbon electricity, the project supports the country’s industrial sector while contributing to global carbon reduction targets.
Future Outlook for Pakistan’s Nuclear Sector
With the construction of C-5 “progressing swiftly,” the Pakistan Atomic Energy Commission continues to position nuclear energy as a vital component of the national energy mix. The plant’s ability to provide reliable baseload power—running at a capacity factor often exceeding 90%—makes it far more dependable than seasonal hydro or intermittent solar and wind sources.
As the 2030 deadline approaches, the Chashma-5 project remains a symbol of technological progress and a beacon of economic hope, promising a future of brighter, more affordable, and cleaner energy for the people of Pakistan.
