🔥 When Sulfur Rules Go Soft: What It Means for Your Portfolio 🏭⚖️
Back in 2015, India set strict rules to control sulfur dioxide (SO₂) from coal plants. Plants had to install expensive FGD (Flue Gas Desulfurization) units to cut down toxic emissions.
But reality hit hard. Most power producers dragged their feet. Only 11% of thermal capacity complied by end-2024. Retrofitting costs were massive — ₹1.5 lakh crore! And no plant got fined. So, on July 11, 2025, the government did the unthinkable — rolled back the sulfur emission rules for most coal plants.
It wasn’t ideal for the environment. But for investors?

Operators saved capital
Tariff hikes were avoided.
Public sector power firms got a lifeline.
