50% freshwater thermal plants fail norms: CSE
BATHINDA: India’s coal-fired power plants have been rampantly flouting the country’s water consumption norms dated 2015, said a new survey report released recently by the Centre for Science and Environment (CSE). Water Inefficient Power, as the report is titled, says that even six years after water consumption norms came into force, the water-guzzling coal power industry is ignoring water regulations and a high degree of non-compliance has been observed in the sector. Counted among the most water-intensive industries in India, the coal power sector is responsible for about 70% of the total freshwater withdrawal by all industries in India. Indian power plants, with cooling towers, consume twice as much water as their global counterparts. According to the 2015 norms (revised in 2018), plants installed before January 1, 2017 were required to meet a specific water consumption limit of 3.5 cubic meters per MWh; plants installed after January 1, 2017 had to meet the norm of 3 cubic meters of water per MWh, apart from adopting zero liquid discharge. Additionally, all freshwater-based plants were required to install cooling towers and subsequently achieve the norm of 3.5 cubic meters of water per MWh. All sea waterbased plants were exempted from meeting the norms. Nivit Kumar Yadav, programme director, Industrial Pollution unit, CSE, said, “This is when many power producing regions of the country are facing acute water shortages. Also, there is huge water pollution due to the power plants’ effluent discharge.”
