Andhra Pradesh gets a new floating solar power plant on Meghadri Gedda reservoir

  • Published
    23rd Jul, 2022
Context

A floating solar power plant commissioned at Meghadri Gedda reservoir in Andhra Pradesh’s Visakhapatnam.

Background

Key points

  • Renewable energy plant: It can save coal up to 54000 tonnes per year.
  • Capacity: It will produce about 2 million units of power each year.
  • Developing entity: Greater Visakhapatnam Municipal Corporation (GVMC)
  • Significance:
    • No need for land acquisition
    • Low-cost energy production
    • Promotion of renewable energy resources

What are Solar Technologies?

  • Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.
  • This energy can be used to generate electricity or be stored in batteries or thermal storage.

Types of Solar plants in India

  • Solar plants can be either;
  • Ground-mounted or
  • Set up on the surface of water-bodies or
  • Though these floating farms are a bit more expensive than the traditional ones mounted on land surfaces.     

Pros

Cons

  • No need for land,
  • Increase in Power generation
  • Easy to maintenance and so on.
  • Less evaporation and algae bloom  

Solar panel needs to be prevented from corrosion.

Reduced shelf-life for metal parts used.

Higher cost of installation.

Needs more maintenance

May lead to water pollution

Common Uses of Solar energy

  • Photoelectric cells
  • Solar power generation
  • Solar heating systems 


Some other to be commissioned power plants

The renewable energy plants that are likely to be are:

  • 25MW floating solar plant at Simhadri thermal power plant near Visakhapatnam
  • 92MW floating solar plant at Kayamkulam in Kerala
  • 100 MW 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 per cent 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
