Improving the environmental performance
of coal utility plants in India

These free workshops shared information which could accelerate the uptake of cost-effective multipollutant control strategies within the coal utility sector in India. Coal-fired power plants contributed 60% of the total particulate matter, 45% of the total SO2, 30% of the total NOX, and more than 80% of the total mercury emissions from all industrial sectors in the country in 2020. The Indian government has set new emission limits for PM, SO2, NOx and mercury from coal plants. However, this legislation and the timeline for its implementation are proving technically and economically challenging for some Indian utilities.

These workshops shared case studies and experiences from within India and internationally. By building on lessons learned and sharing knowledge specific to the Indian challenge (such as water scarcity, high ash coals and high-flexing plants) we hope to promote the uptake of new strategies, techniques and technologies in India which will fast-forward emission reduction. We were particularly keen on promoting new multipollutant methodologies which could cost-effectively reduce several pollutants simultaneously. With over 200 GW of coal power in place in India and more planned, the market for new control systems is significant.
