Integrated Annual Report 2021-22
More Power through better stewardship

As an integrated energy player, we are dependent on the continued availability and accessibility of renewable and non-renewable natural resources such as coal, water, sunlight, wind and other raw materials. Across our operations, we progressively strive to leave behind a greener footprint, and have specific goals concerning the various aspects of natural capital conservation and preservation, and our alignment to a greener and more environmentally sustainable organisation.

Our sustainability aspirations

We have taken on record specific aspirations regarding overall environmental sustainability, which are aligned to our Group strategy and goals. These aspirations are housed under three broad levers.


  • Achieve clean and green portfolio of 80% by 2030 and 100% before 2045
  • Grow through low carbon businesses (Distribution, New Businesses)

ESG and environment

  • ESG rating improvement and inclusion in S&P Global Emerging Market List by 2027
  • Become carbon net zero before 2045
  • Become 100% water neutral before 2030
  • 100% zero waste to landfill before 2030
  • No Net impact on Biodiversity before 2030


  • Leverage technology to create the ‘Utility of the Future’ (IoT, Smart Grids, BESS, Green H2, robotic panel cleaning etc.)

UN Sustainable Development Goals

Climate action and green energy leadership

One of the biggest trials humanity is facing today is climate change and as a responsible corporate, we have taken early action to contribute to the global agenda of climate action. Through conscious steps including growth through decarbonised and digitalised energy models; committing to no fresh coal based investments; ramping down thermal capacity at the end of contractual obligations, and adopting water and waste circularity, we continue to demonstrate our strong commitment to sustainable economic development. Further, we pursue our economic and environmental goals, while aiming to provide last-mile energy access through decentralised power generation and reliable models of distribution.

By aligning our business vision with the global UNSDG agenda, we have strengthened our ESG focus in its journey of being the 'Utility of the Future'. We are empowering customers with green choices, and are enabling communities by making them future-ready. As a major milestone in our climate action journey, we have committed to the Science-Based Targets initiative (SBTi), doing our part to keep the rise of global temperature well below 2°C, with the leadership goal of becoming carbon net neutral before 2045.

We are a signatory to TCFD and are committed towards alignment with TCFD Framework for Climate Change related Risk and Opportunity assessment and mitigation.


Each of the identified risks have mitigation and contingency plans outlined and integrated within our long-term strategy.

Tata Power strives to accelerate its short-term and long-term ESG goals by leveraging innovation, digitalisation, and technology transformation and has adopted a circular economy framework. In line with our sustainable business approach of 'Leadership with Care’, we are pioneering inclusive energy transition and creating long-term value for stakeholders while carving a leadership niche of becoming the 'Most Preferred Green Energy Brand’.

Air emissions

Apart from GHG emissions, we take cognisance of the various other air pollutants such as oxides of sulphur and nitrogen and particulate matter, generated by our operations. To manage these emissions, we have implemented state-of-the-art equipment to reduce these at source, and manage them before releasing into the environment. The technologies and mechanisms we deploy to minimise air emissions include electrostatic precipitators, monitoring devices for carbon monoxide emissions, flue gas desulphurisation.

Air emissions profile

Auxiliary power consumption (APC)

We continuously optimise our auxiliary power consumption (power used for own operations), through various measured such as stopping electrical equipment usage during low load operations and introduction of more power-efficient devices for lighting.

Station Heat Rate (SHR)

We lay constant focus on improving the overall conversion efficiency of our plants and generation systems. Such initiatives enable more power per unit of input material, while reducing wastage, cost and GHG emissions.

Water management

A significant part of our generation portfolio still depends on thermal power generation, which uses substantial amounts of water for operational purposes. With water being a scarce and common resource, we are progressively reducing our dependence on freshwater and are taking proactive measures such as rainwater harvesting to achieve water neutrality before 2030.


From a discharge standpoint, most of our thermal units have attained a Zero Liquid Discharge (ZLD) status (excepting seawater used for cooling), and the quality of discharge in other locations is managed as per regulatory norms. The recycled water from Sewage Treatment Plants at our locations is used for gardening purposes.

Water withdrawal and consumption by source

Specific Water Consumption (m3/mWh)

The Government of India, through a Gazette Notification in 2015 and subsequent amendments, mandated limits on fresh water for specific water consumption for coal fired thermal power generation. This is 3.5 m3/Mwh for units commissioned prior to 01-01-2017 and 3.0 m3/Mwh for others. Tata Power's specific water consumption falls within this metric across units, as illustrated below.

Note: Specific water consumption at CGPL and Trombay considers water used for steam generation only. Cooling requirements are excluded as both plants utilise sea water for cooling.

Raw material management

Our dependence on conventional fuels and raw materials are gradually decreasing, with our portfolio becoming greener. This portends to a reduced raw material risk for us as an organisation, and reduced extraction of limited natural resources such as coal, benefiting the environment.

Raw material consumption

Waste management

At Tata Power, we are setting up the blocks to contribute to a circular economy at large. We have taken solid strides in proactive waste management practices across our value-chain, including maximisation of fly-ash utilisation and progressing to zero waste to landfill (in cases of PV panel disposal). Similarly, before the start of any project, we assess the proposed operations for best-in-class waste management practices and take the best possible way forward. Considering an average of 25 years life for PV panels, we also expect the waste from PV panels to go up post 2035 and are planning for future courses of action accordingly.

Our ambitions include 100% fly ash utilisation and zero waste to landfill before FY30

Waste diverted from disposal


The hydro catchment areas in and around our hydro plants are rich in biodiversity and genetic material. They are closely linked to ecological and social sustainability as well. At Tata Power, we are cognisant of our responsibility towards ensuring biodiversity conservation and we undertake biodiversity-related interventions under the following broad areas:

  • Protection to existing flora and fauna
  • Increasing Green cover
  • Prevent soil erosion and reduce siltation
  • Provide minor forest produce for the local villagers
