NTPC’s has got the approval from government of Odisha for stage III expansion plan of Talcher Thermal Power Station project. The expansion involves setting up 1,320 (2 x 660 MW) supercritical units, with an investment of Rs 7,698 Cr. The first unit of stage III is expected to be commissioned by 2022 and the second unit by 2026. The project shall be established in the existing premises of 460 MW Talcher Thermal Power Station.
Existing NTPC Talcher Plant
The Talcher power plant is a coal-fired thermal station located in Talcher, Angul district of Odisha, India. This is the implementation of stage three of the project. Stage one had installed capacity of 240 (4X60 MW) and stage two had 220 (2×110 MW).
In 2018 the Board of Directors of NTPC had given the clearance for expansion of the project including scrapping of the existing six units of Stage- I & II 460 MW (4x 60 MW +2 x 110MW) of the thermal power station.
New NTPC Talcher Power Project
Stage three will have two pulverised coal-fired units of 660MW each, supercritical boilers, single reheat steam generators with dry bottom type furnaces.
The project shall also comprise of coal storage area, fly ash silos, ash slurry disposal system and light diesel oil (LDO) tanks for initial start-up. Also, it shall have a pump house, water treatment plant, cooling tower, and cooling water pump house.
A sewage treatment plant will also be installed for the treatment of sewage and its effluents will be utilized for plantation and horticulture.
Coal Handling at this Talcher project
6.9Mtpa (Million Tonnes per Annum) of coal is estimated to be required for stage three, which shall be sourced from Mahanadi coal fields located in Talcher area.
A new coal handling system of 2,200 MTph (Metric Tons per Hour) capacity with parallel double stream belt conveyors will be installed. The system will have facilities for receiving, unloading, crushing and conveying the crushed coal to boiler bunkers and stacking the coal from crushed coal stockyards. The storage capacity of stockyards will be equivalent to eight days of coal consumption of the two units.
