Overview
NTPC is principally engaged in the generation of bulk power for sale to State Electricity Boards, distribution utilities and other bulk consumers. While its core business has historically been coal-based thermal generation, the company has progressively diversified into gas-based generation, hydroelectricity, renewable energy (solar and wind), and has stated ambitions in nuclear power, hydrogen and e-mobility. NTPC also undertakes consultancy, project management and operation and maintenance services in the power sector.
Background
NTPC was incorporated in 1975 to plan, promote and organise the integrated development of thermal power in India at a time when electricity shortages were a binding constraint on industrial growth. Over the following decades, the company evolved from a single-purpose thermal generator into a diversified utility, and its name was formally changed from National Thermal Power Corporation Limited to NTPC Limited to reflect this broader portfolio.
Operations and business segments
- Coal-based generation: The largest share of NTPC's installed capacity comprises pithead and load-centre coal-fired stations spread across India.
- Gas/liquid fuel-based generation: Combined-cycle and open-cycle stations using natural gas and, where required, liquid fuels.
- Hydroelectric generation: Hydropower projects developed directly and through joint ventures.
- Renewable energy: Utility-scale solar parks and wind projects, executed by NTPC and its renewables subsidiary.
- Coal mining: Captive coal mining to support fuel security for its thermal fleet.
- Consultancy and services: Engineering, project management, operations and maintenance services within India and abroad.
Subsidiaries and joint ventures
NTPC operates through a group structure that includes wholly owned subsidiaries and joint ventures with other public sector undertakings, state utilities and foreign partners. These include entities focused on renewable energy, hydropower, electricity trading, and specific power projects in collaboration with state governments.
