India's Nuclear Energy Ambitions: Expanding Capacity to Meet Electricity Demand and Decarbonization Goals

India, the world's third-largest energy consumer, is rapidly expanding its nuclear energy sector to meet soaring electricity demand and reduce greenhouse gas emissions. According to the World Nuclear Association (WNA) Director General Sama Bilbao y León, India aims to triple its nuclear capacity to 60 GW by 2040, up from the current 7 GW [1].

Speaking with Menaka Doshi at India Energy Week 2026, Bilbao y León explained that India's nuclear energy expansion is driven by its growing electricity demand, which is expected to reach 450 GW by 2030 [2]. The country's electricity demand grew by 10% in 2025 alone, and the government aims to provide electricity to all its citizens by 2027 [3].

Moreover, India is committed to reducing its carbon emissions and meeting its net-zero targets. Nuclear energy, which produces no greenhouse gas emissions during operation, is a key component of India's decarbonization strategy. The country aims to increase the share of nuclear power in its energy mix to 20% by 2030 [1].

Bilbao y León highlighted the strategic importance of nuclear energy for India, which faces energy security challenges due to its heavy dependence on imported fossil fuels. Nuclear energy provides India with an indigenous energy source, reducing its reliance on imports and enhancing its energy security [4].

India's nuclear energy expansion involves building new nuclear power plants and upgrading existing ones. The country plans to build six new pressurized heavy water reactors (PHWRs) at the Kudankulam site in Tamil Nadu, which will add 2,000 MW of nuclear capacity [1]. India is also exploring small modular reactors (SMRs) as a potential solution for decentralized power generation and grid stability [5].

However, India's nuclear energy expansion faces challenges, including financing, regulatory hurdles, and public opposition. The country needs to attract significant foreign investment to finance its ambitious nuclear energy program [6]. India's regulatory framework for nuclear energy is still evolving, and the country needs to streamline its regulatory process to attract investment [7]. Public opposition to nuclear energy, particularly in the wake of the Fukushima disaster, remains a challenge for India's nuclear energy program [8].

Despite these challenges, India remains committed to expanding its nuclear energy sector. The country's nuclear energy expansion is expected to create significant economic opportunities, including job creation and supply chain development [9]. India's nuclear energy sector is poised to become a key driver of the country's economic growth and energy security.
