India has dismantled its decades-old state monopoly in the nuclear energy sector by permitting private firms to mine, import, and process uranium, a historic step designed to supercharge clean energy growth and attract major investments. This regulatory shift aligns with Prime Minister Modi’s vision for energy independence, aiming to scale up nuclear power capacity twelvefold by 2047, with nuclear energy expected to meet 5% of India’s total electricity demand.

Before this, nuclear power production and uranium fuel mining were the sole domains of government. The new system will enable eligible Indian and some foreign companies to become part of fuel mining, supply, and even minority interests in nuclear facilities.
