Tamil Nadu Power Generation Corporation Limited (TNPGCL) is a state-owned electric power generation company headquartered in Chennai, Tamil Nadu, India. The corporation is responsible for operating thermal and gas-based power plants in the state and generating electricity for the Tamil Nadu power grid. It functions as a subsidiary of TNEB Limited and operates under the administrative control of the Government of Tamil Nadu.
The company was formed in 2024 following the restructuring of the Tamil Nadu Generation and Distribution Corporation (TANGEDCO), under which the power generation, power distribution and renewable energy operations were separated into independent companies.
Electricity generation and distribution in Tamil Nadu were historically managed by the Tamil Nadu Electricity Board (TNEB). In 2010, the board was reorganised into a holding company called TNEB Limited, with separate subsidiaries for transmission and generation-distribution activities.
In 2024, the Government of Tamil Nadu further restructured TANGEDCO to improve operational efficiency and financial management. The restructuring created three new companies:
Following this reorganisation, thermal power stations and gas turbine plants previously managed by TANGEDCO were transferred to TNPGCL.
TNPGCL operates coal-based thermal power stations and gas turbine power plants across Tamil Nadu. These facilities form an important component of the state's electricity supply and help meet peak power demand.
