NTECL - Powering the States ...

NTECL is a 50:50 Joint Venture Company formed between NTPC and Tamil Nadu Generation and Distribution Company Ltd (TANGEDCO). Vallur Thermal Power Station (VTPS) with a capacity of 1500 MW (3 Units of 500 MW), sole power plant of NTECL is situated at Vallur village of Ponneri Taluk, Tiruvallur Dist of Tamilnadu. The power plant was established under the mega power project policy of the central government. This power plant was commissioned to its full capacity and operating since 2015 and around 70 per cent power from this station is supplied to Tamil Nadu and the rest to neighboring states like Andhra Pradesh, Karnataka, Kerala, Telangana and Pondicherry. The plant consumes approximately 9 MMT of coal in a year. The coal is brought from the Mahanadi Coal fields, Central Coal Fields, Eastern Coal Fields ,etc through rail cum sea to Ennore Port. From there it is transported by a 4.2 KM long pipe conveyor with a capacity of 4000TPH speed to the plant. This pipe conveyor is one of the important features of this plant for dust free operation over the Ennore creek to ensure the environment protection. The unique feature of this plant is that the total plant water requirement is met from sea water. Being close to the sea, this plant has a sea water desalination unit of 20MLD capacity. This takes care of the entire water requirements. The power generated in this plant is fed to the grid through the 400KV Gas Insulated switchyard. This switch occupies 80 per cent lesser space than the conventional Switch Yard. Though the initial cost of the GI Substation is high, the sophistication, less space and the reduction in further maintenance costs are benefits of the system.
