PROJECT SYNOPSIS:

 

VINDHYACHAL SUPER THERMAL POWER PROJECT STAGE-IV (2 X 500 MW) COAL HANDLING PLANT PACKAGE

 

Vindhyachal STPP was conceived as a pit head coal based super thermal power plant of 3260 MW (6X210 MW+2x500 MW + 2x500 MW) capacity for which land was acquired during Stage-I of the project. Stage-I, II & III of the project comprising of six units of 210 MW (Stage-I), two units of 500MW (Stage-II) and two units of 500 MW (Stage-III) each is under operation.
The present proposal is to install 2 units of 500MW each in Stage-IV, thus making the capacity of the project to 4260 MW (6x210MW + 2X500 MW + 2X500 MW + 2x500MW).

LOCATION AND APPROACH:
The proposed power station is located in Sidhi district of Madhya Pradesh, having a latitude and longitude of 2406'N and 820 40'E respectively. The site is situated on the North-Western bank of Rihand reservoir and is confined within the boundaries of the Singrauli STPP discharge channel towards South, Ballia nalla towards East, power corridor of SSTPP and Jayant Mine Township towards North. Renukoot, the nearest town, is about 50 kms away from the project site. The approach road for Vindhyachal STPP has been drawn from the peripheral road of Singrauli STPP.
The nearest broad gauge rail head Shakti Nagar Railway Station, is approximately 2.0 km away from the project site.
