  • 197
    Number of Coal Fired Thermal Power Stations that reported data related to utilisation of Fly Ash during the financial year 2019-20.
  • 200,691 MW
    Installed capacity of all the thermal plants combined for the financial year of reporting.
  • 678.88 million tonnes
    Amount of coal consumed by these coal fired power plants during the financial year of reporting.
  • 226.13 million tonnes
    Fly Ash generated during the financial year. Fly Ash is left behind when coal is burnt. Coal-fired power plants are the biggest sources of fly ash, which contains toxic chemicals such as arsenic, barium, cadmium, nickel and lead, among others. These are known to cause cancer, lung and heart ailments and neurological damage, and contribute to premature mortality.
  • 187.81 million tonnes
    Fly Ash utilised in the year for manufacturing brick /blocks/tiles; cement manufacturing, ready mix concrete; construction of road and fly over embankment; ash and geo-polymer-based construction material; construction of dam; filling up of low lying areas; filling of mine voids; manufacturing of sintered/ cold bonded ash aggregate among others.

  • 33.32%

  • 91
    Number of power stations that were able to utilize 100% or more than 100% of the fly ash generated in the year.
  • 27
    Number of power stations that were able to utilize >90% but <100% of the fly ash generated in the year.
  • 21
    Number of power stations that were able to utilize >70% but <90% of the fly ash generated in the year.
  • 16
    Number of power stations that were able to utilize >50% but <70% of the fly ash generated in the year.
  • 28
    Number of power stations that were able to utilize <50% of the fly ash generated in the year.
  • 14
    Number of power stations which have not generated any significant fly ash or any fly ash.
  • 21 Dec 2017
    Deadline set for power stations to ensure 100% fly ash utilisation per a notification issued by the Ministry of Environment, Forest and Climate Change on 25 Jan 2016.
  • 22 Apr 2021
    Ministry issues new notification. Power plants with utilisation of 60% to 80% will get 4 years while those with utilisation <60% will get 5 years time to ensure 100% fly ash utilisation. It also gives 10 years to thermal power plants to utilise the unutilised fly ash, or legacy ash which is stored. Non-compliant power plants will be slapped a fine of ₹1,000 per tonne on unutilised ash during the end of the deadline.
  • 40,000 hectares
    Land used across India for disposal of fly ash. Conventional disposal for fly ash in the form of slurry, which means there is a demand on water as well.
  • 1,040,000 million litres
    Water used annually for fly ash disposal in slurry form in India. Power plants use water to flush the rejected or excess unutilized fly ash into large holding ponds or dykes called 'pond ash'. “Coal ash ponds are one of the biggest sources of air pollution,” according to Shweta Narayan of Healthy Energy Initiative. “Communities living close to coal ash ponds often experience coal ash storms during the dry seasons.”
