The competitive landscape is undergoing significant consolidation as policy uncertainty reshapes market opportunities across the thermal power sector.

India Market Dynamics

FGD Mandate and Thermal Power Plant Compliance
The MoEF&CC's 2015 emission norms, reinforced through the September 2022 notification, mandated FGD installation across thermal power plants with phased timelines: Category A plants (within NCR or million-plus cities) by December 2024, Category B by December 2025, and Category C by December 2026. The CPCB in its February 2023 FGD guidelines confirmed that 95% of coal's sulphur converts to SO₂. As of July 2023, 22 units with 9,280 MW capacity had installed FGDs, with 537 units identified for installation. Non-compliance attracts environmental compensation of ₹0.20-0.40 per unit.

FGD Policy Uncertainty and Market Disruption
The MoEF&CC's July 2025 notification fundamentally disrupted the FGD market by exempting approximately 79% of India's thermal power capacity from mandatory FGD installation. Plants outside a 10-km radius of million-plus cities are now exempt, while those within are evaluated case-by-case. This policy reversal has left engineering companies with large investments at risk. The original December 2027 deadline remains only for NCR and million-plus cities. Thermal power plants retiring before December 2030 are exempt from SO₂ standards.



CPCB NPL Registration and Quality Standardization
The CPCB has launched mandatory NPL registration for manufacturers of scrubbers, bag filters, cyclones, and ESPs. The National Physical Laboratory (NPL), operating under CSIR, serves as India's national standards laboratory, evaluating design, manufacturing capacity, and testing protocols. This initiative aims to build a verified database of competent manufacturers, enhance system design and efficiency standards, ensure compliance with national emission norms, and prevent substandard systems from entering the market.

Segment Analysis

India Scrubbers System Software Market by Scrubber Type
