Central Pollution Control Board (CPCB) Issued Directions to Thermal Power Plants to Ensure Compliance as Per the Plan

  • A phased implementation plan for installation of Flue Gas De-Sulphurization (FGD) and other emission control equipment was prepared by Ministry of Power and submitted to Ministry of Environment, Forests and Climate Change

  • The plan is to be used in plants for a capacity of 1,61,402 MW (414 Units) and upgradation of Electrostatic Precipitator in plants for a capacity of 64,525 MW (222 units) was prepared by Central Electricity Authority.

    • The plants which do not have space for setting up of FGD systems, are to explore alternate technologies such a

    • Wet scrubbing

    • Spray-dry

    • Wet sulfuric acid process

    • dry sorbent injection

    • use of low sulphur coal to comply with the new norms.

  • The first major FGD unit at a utility was installed in 1931 at Battersea Power Station, owned by London Power Company.
