NTPC seeks ₹1.5-trillion Rosatom tie-up for six nuclear reactors

NTPC has proposed taking responsibility for six nuclear units originally covered by a 2014 agreement between India and Russia. That agreement envisaged 12 reactors in India with Russian state-owned Rosatom. The proposal matters because it could expand India’s nuclear fleet through an existing government-to-government framework rather than starting a new partnership process.

NPCIL is implementing six Russian-linked units at Kudankulam, Tamil Nadu. Two are already operating, and four are under construction. NTPC wants the other six units allocated to it. It has offered to use Rosatom’s VVER 1000 reactors, with each unit rated at 1,000 MW.

The proposal has not yet been confirmed by the government or the companies. NPCIL said its six Kudankulam units would ultimately provide 6,000 MW, but it gave no information about NTPC’s plan. NTPC’s wider goal is 30GW of nuclear capacity by 2047.

NTPC’s proposed project is large by any measure: six nuclear reactors would deliver a combined 6,000 MW, equal to 6GW. The scale matters because nuclear plants provide substantial generating capacity from a relatively small number of large units. The project would also form a major part of NTPC’s planned expansion into nuclear power.

Each proposed reactor would be a Rosatom VVER 1000 unit with a capacity of 1,000 MW. The estimate uses an industry cost of ₹25 crore per megawatt. Multiplying that benchmark by 6,000 MW produces an estimated capital expenditure of ₹1.5 trillion.

This is a proposal, not an operating project. The article does not report final government approval, construction dates, or selected locations for these six units. Separately, NTPC has identified sites in Madhya Pradesh, Bihar, and Odisha for additional nuclear capacity, with 2-4GW planned at each location.

NTPC is India’s state-run power company seeking a larger role in nuclear generation. It has proposed taking six units from the India-Russia agreement and aims to reach 30GW of nuclear capacity by 2047. Its subsidiaries are also pursuing projects, including capacity at Rajasthan’s Mahi Banswara site.

NPCIL, operating under the Department of Atomic Energy, has been India’s sole nuclear power generator since 1987. It currently runs 24 reactors with combined capacity of 8.78GW. At Kudankulam, NPCIL is implementing six 1,000MW PWRs or VVERs with Russia; two operate and four are under construction.

Rosatom is Russia’s state-owned nuclear company and the technology partner in the existing agreement. NTPC proposes using Rosatom’s VVER 1000 reactors for its six units. The article also reports NTPC discussions with other international companies, including French firm EDF, but those partnerships may require competitive bidding.

VVER 1000 refers to a Russian pressurized water reactor design rated at 1,000 MW. The article identifies these units as PWRs or VVERs and says NTPC has offered to deploy six of them. The name therefore describes both the reactor family and its planned electrical capacity.

Inside the reactor, nuclear fission releases heat. That heat warms water under pressure, preventing it from boiling in the reactor circuit. A heat exchanger transfers energy to a separate water circuit, producing steam. The steam spins a turbine connected to an electricity generator. The steam is then cooled back into water and reused. This operating explanation uses established nuclear-power knowledge beyond the article’s brief description.

For NTPC’s proposal, the key mechanism is repetition at scale: six 1,000 MW units would produce 6,000 MW in total. Rosatom would provide the reactor technology, while the Indian project structure remains subject to government decisions.

India expects nuclear power to help its electricity system as coal-based generation declines. The article describes nuclear energy as a clean, non-fossil fuel source that can provide baseload power. That steady output matters because the grid needs dependable supply, not only power that varies with demand or weather.

The planned expansion combines large reactors with smaller designs. The government’s approach includes 700 MWe indigenous pressurized heavy water reactors and advanced reactors at new sites. It also supports small modular reactors at existing fossil-fuel plants, captive industrial facilities, and remote off-grid locations. NTPC is targeting 30GW of nuclear capacity by 2047.

Nuclear expansion remains a long-term programme, not an immediate replacement for coal. India’s strategy is also guided by its three-stage nuclear programme and the goal of using thorium reserves sustainably. Proposed sites and partnerships still require approvals, investment, and implementation.

Foreign nuclear technology partnerships are difficult to arrange through ordinary commercial competition. The article says international nuclear companies interested in India after the Shanti Act are not very keen to enter through tenders. That makes a direct government-to-government agreement especially important for securing reactor technology and bilateral cooperation.

The India-Russia pact illustrates the mechanism. Signed in 2014, it covers 12 reactors. NPCIL is implementing six at Kudankulam with Rosatom, and NTPC has suggested receiving the remaining six. Because the partnership already exists at the government level, NTPC views this route as smoother than creating a new tender-based arrangement.

This does not eliminate competition across India’s nuclear plans. NTPC is discussing other partnerships, including an MoU with France’s EDF, but those vendors would have to participate through competitive bidding. The Shanti Act allows foreign and private firms to enter the sector while retaining strict safety and safeguards requirements.

Nuclear power provides steady electricity because reactors are designed to produce continuous output for the grid. This is called baseload power. The article says that dependable supply can support grid stability as coal-based generation declines. Nuclear generation therefore fits India’s effort to add reliable non-fossil electricity.

A reactor releases heat through nuclear fission. The heat produces steam, and the steam turns a turbine connected to a generator. Unlike renewable sources whose output can vary with sunlight or wind, a reactor can operate for long periods under controlled conditions. This basic electricity-generation explanation draws on established world knowledge; the article itself focuses on nuclear power’s baseload role.

Nuclear is called non-fossil because it does not burn coal, oil, or gas to generate electricity. It is non-renewable because its fuel resources are finite and are not replenished on a human timescale. India’s long-term strategy also includes thorium use and newer reactor designs.
