GST Reform Boosts Coal Sector, Cuts Power Costs

India's Goods and Services Tax (GST) regime for coal has been significantly revised, leading to a rationalization of tax burdens across different coal grades. This reform is projected to bring down the average price of coal supplied to the power sector by approximately ₹260 per tonne. The changes address previous issues where lower-grade and lower-priced coal faced a higher effective tax incidence.

Rationalizing the Tax Burden

• The previous GST structure resulted in an inverted duty issue, where coal companies paid higher GST (5% to 28%) on inputs and services than the 5% output GST on coal itself. This led to the accumulation of unutilised Input Tax Credit (ITC).
• By increasing the output GST rate on coal to 18%, the government has corrected this inverted duty structure, aligning input and output tax rates.
• This alignment is expected to release significant amounts of blocked liquidity tied up in unutilised ITC, enhancing the financial health of domestic coal producers.

Impact on Power Generation and Imports

• The average reduction of ₹260 per tonne in coal prices for the power sector is anticipated to reduce the cost of power generation by an estimated 17 to 18 paise per kilowatt-hour (kWh).
• Removing the GST Compensation Cess of ₹400 per tonne further enhances the competitiveness of domestic coal against imported varieties.
• This incentivizes import-based power plants and other consumers to switch to cheaper domestic coal, aligning with the 'Aatmanirbhar Bharat' and import substitution goals.
• According to ICRA, the removal of compensation cess, despite the GST rate increase, is expected to lower power generation costs for coal-based producers by about 15 paise per unit. Given that coal accounts for about 70% of India's power generation, this could lead to a reduction of around 12 paise per unit in the cost of supply for Discoms.

Industry Demand and Future Strategy

• Rationalizing coal cess has been a long-standing demand from the industry.
• The Coal Ministry previously set up an Inter-Ministerial Committee (IMC) to develop a strategy for import substitution by 2030, with a goal to cease coal imports by the power sector by FY26.
• The IMC had suggested in March 2025 that GST compensation cess should be ad-valorem (based on price and quantity) rather than a fixed ₹400 per tonne, noting the flat rate often made imports comparatively more attractive regardless of quality or price.

Impact

• This GST revision directly benefits the power sector by reducing input costs, potentially leading to lower electricity tariffs for consumers and improved financial performance for Discoms.
• Domestic coal producers gain a competitive edge, potentially reducing India's reliance on coal imports.
• The overall economy could see reduced inflationary pressures due to lower energy costs.
• Impact Rating: 9/10
