Tamil Nadu Green Energy Corporation Limited (TNGECL) is a state-owned renewable energy company of the Government of Tamil Nadu. It was established in 2024 following the restructuring of Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO) to focus exclusively on renewable energy development including hydro, solar, wind and energy storage projects.[2]
The company was formed by transferring the renewable energy activities of TANGEDCO and merging the Tamil Nadu Energy Development Agency (TEDA) into the new corporation.[2][3][4]
TNGECL operates as a subsidiary of Tamil Nadu Electricity Board (TNEB) and is responsible for expanding renewable energy capacity as part of Tamil Nadu's clean energy transition.[5]
Electricity generation in Tamil Nadu was historically managed by the Tamil Nadu Electricity Board. In 2010, the board was reorganised into TNEB Limited with operational subsidiaries.[6] In January 2024, the Government of Tamil Nadu approved further restructuring of TANGEDCO into separate generation, distribution and renewable energy companies to improve operational efficiency and accelerate renewable energy adoption.[2] As part of this reform Renewable energy activities were transferred to TNGECL[7] TNGECL also absorbed the functions of TEDA, which had previously served as the nodal renewable energy promotion agency of the state.[8]
