Tiroda town is about 5.0 km from the site. Domestic coal from SECL will be used as fuel for 1x660 MW . For 2x660 MW units, imported coal from South Africa is proposed to be used. Ash and sulphur content in domestic coal to be used will be 34% and 0.5 % respectively. Ash and sulphur content in imported coal will be 32% and 0.3 % respectively. Domestic coal requirement for 1x660 MW will be 2.89 MTPA and for 2x660 MW imported coal requirement will be 2.72 MTPA (per unit). Total coal requirement will be 8.36 MTPA. Water requirement of 90 mcm/annum will be obtained from Wainganga river which flows at a distance of 5 km from the site. Allotment of 90 mcm/annum is in place. Nagzira wildlife sanctuary is located at a distance of 11.0 km from the site. Cost of the expansion project will be Rs. 9696.0 Crores.
