Indian Coal Grading System (GCV-Based)

In India, coal is classified into different grades based on its Gross Calorific Value (GCV) measured in kcal/kg. This classification is widely used by coal producers and industries for pricing and determining its appropriate industrial applications.

Coal Grades and GCV Range

Grade Gross Calorific Value (GCV) Range (kcal/kg) Industrial Use

• G1 Above 7000 Metallurgical processes, steel production

• G2 6701 - 7000 Power plants, cement, and industrial boilers

• G3 6401 - 6700 Cement and captive power plants

• G4 6101 - 6400 Thermal power plants

• G5 5801 - 6100 Power plants, sponge iron plants

• G6 5501 - 5800 Power generation, paper industry

• G7 5201 - 5500 Brick kilns, textile industries

• G8 4901 - 5200 Thermal power plants

• G9 4601 - 4900 Cement plants, small power units

• G10 4301 - 4600 Thermal power and captive power plants

• G11 4001 - 4300 Brick manufacturing, boilers

• G12 3701 - 4000 Power generation, general industrial use

• G13 3401 - 3700 Low-end industrial boilers

• G14 3101 - 3400 Used in blending and low-grade applications

• G15 2801 - 3100 Domestic use, small industrial purposes

• G16 2501 - 2800 Low-grade industrial use

• G17 2201 - 2500 Domestic heating, clay manufacturing

Industrial Uses by Coal Grade

• G1 to G3: Premium coal used in steel production, cement manufacturing and metallurgical industries.

• G4 to G6: Medium-grade coal used in power generation.

• G7 to G12: Commonly used in thermal power plants.

• G13 to G17: Low-grade coal used for domestic heating and small-scale industries.
