In a remarkable achievement, NTPC has elevated its Environmental, Social, and Governance (ESG) Score by two levels, transitioning from a ‘D’ rating in 2022 to a commendable ‘C’ rating in 2023, in the Carbon Disclosure Project (CDP) Water Security Rating. This milestone serves as a testament to NTPC’s unwavering commitment to environmental stewardship and sustainable practices, particularly in the area of water management.
The transition to a higher rating comes as a result of NTPC’s relentless efforts to enhance water reuse and recycling, leading to a significant decrease in specific water consumption in recent years. NTPC has confronted challenges posed by renewable energy integration and the implementation of wet flue gas desulfurisation systems head-on, actively reducing water consumption through innovative measures and efficient practices.
The Carbon Disclosure Project (CDP) is one of the leading ESG rating agencies worldwide, evaluating companies on their environmental performance, particularly in the areas of climate change, water security, and deforestation.
In a bid to strengthen its commitment to water management, NTPC became a signatory of the CEO Water Mandate in 2021, underscoring its dedication to responsible water management and participation in a global initiative aimed at addressing water sustainability challenges.
Key initiatives undertaken by NTPC towards water conservation include optimisation of water consumption through advanced technologies and process reengineering, implementation of robust ‘Water Policy’ and ‘Rainwater Harvesting Policy,’ and maintaining a ‘Zero Liquid Discharge (ZLD)’ status across all its stations.
Moreover, NTPC has deployed Air-Cooled Condensers, potentially saving 75% of water, while also making community investments in freshwater availability and capacity building, and increasing Cycles of Concentration (CoC) at all stations to reduce freshwater intake.
