Pakistan’s nuclear electricity production rose 3.7 per cent to a record 22.5 terawatt-hours (TWh) in 2025. The increase came as solar generation expanded even faster, according to the World Nuclear Industry Status Report 2026.
The report said nuclear output increased from 21.7 TWh in 2024 to 22.5 TWh last year. Meanwhile, solar power generated 36.3 TWh, surpassing nuclear production for the first time by a significant margin.
Solar Generation Surpasses Nuclear Output
Pakistan currently operates six nuclear reactors with a combined capacity of 3,262 megawatts. China National Nuclear Corporation built all six reactors, including Kanupp-2 and Kanupp-3 near Karachi and four reactors at the Chashma nuclear power station.
Additionally, CNNC is constructing another 1,000MW Hualong One reactor at Chashma. Authorities expect the Chashma-5 project to become operational by 2030, following construction that formally began in December 2024.
Pakistan’s Solar Expansion Accelerates
The report also highlighted Pakistan’s rapid expansion of solar power. Between 2017 and mid-2026, the country imported more than 58GW of solar panels from China, with 40GW arriving during the two and a half years from 2024 to mid-2026.
Consequently, Pakistan became China’s largest customer for solar panels in 2025. By summer 2025, solar power had become the country’s largest single source of electricity, although much of the generation came from private installations outside the public grid.
The report noted that Pakistan installed roughly twice as much solar capacity in five years as France installed over a decade. Meanwhile, nuclear generation continued reaching new records despite the country’s growing shift toward renewable energy.
