The country’s biggest floating solar power plant to date being developed at Ramagundam in Peddapalli district of Telangana is set to be commissioned in next few months.

About the Solar plant

  • Renewable energy plant: It is the biggest solar power plant developed in India to date.
  • Capacity: It is a 100-megawatt plant which is the biggest in terms of generation capacity.
  • Developing entity: It would be one of the renewable (solar) energy plants being developed by NTPC with an installed capacity of 447MW in the Southern Region.
  • FGDs construction: Flu gas de-sulphurization (FGD) capacity will be installed on the developing solar plants to abide by the environmental protection norms.
  • Significance:
    • No need for land acquisition
    • Low-cost energy production
    • Promotion of renewable energy resources

Some other to be commissioned power plants

  • The renewable energy plants that are likely to be commissioned in the next three months are:
    • 25MW floating solar plant at Simhadri thermal power plant near Visakhapatnam
    • 92MW floating solar plant at Kayamkulam in Kerala
    • 100MW plant at Ramagundam.

Flue-gas desulfurization (FGD)

  • It is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants.
  • It also removes emissions of other sulfur oxide emitting processes such as waste incineration.
  • flue-gas desulfurization (FGD) may remove 90 percent or more of the SO2 in the flue gases
  • Common methods used for FGD
  • Wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime, or seawater to scrub gases
  • Spray-dry scrubbing using similar sorbent slurries
  • Wet sulfuric acid process recovering sulfur in the form of commercial quality sulfuric acid
  • SNOX Flue gas desulfurization removes sulfur dioxide, nitrogen oxides, and particulates from flue gases
  • Dry sorbent injection systems that introduce powdered hydrated lime (or other sorbent material) into exhaust ducts to eliminate SO2 and SO3 from process emissions
