Environmental Management

We continually strive towards sustainable development by trying to find a balance between the needs of our customers and responsible care for the environment. We are committed to protect and promote the environment.  We have a well-defined Environment Policy and all our plants have environmental management system in place. Tata Power has established a Corporate Safety, Health & Environment Department (C-SHE) which is responsible for all environmental and safety activities in the company.  Driven by our commitment to power generation harmonious with nature, Tata Power has taken concrete steps to sustain the ecological balance.

Making Positive Environment Impact:

Over Rs.100 crores have been invested on pollution control equipment at the Trombay Thermal Power Plant to install:

• India’s first-of-its-kind Flue Gas-De-sulphurisation (FGD) plant to reduce sulphur dioxide emissions in flue gas, based on the sea-water scrubbing principle.
• Electrostatic Precipitators of 99.5% efficiency.
• Tall Chimneys (152 m and 275 m) to limit the ground level concentration of pollutants.
• Low NOx burner to minimise NOx Pollution.

Our power stations are clean and environmentally sound. Instruments for continuous on-line sampling and analysis of the flue gases, closed circuit television for monitoring stack emissions and a Continuous Ambient Air Monitoring Station have been provided. Annual environmental statements are submitted to the Government Authorities as per their guidelines. Tata Power will strive to go beyond simple compliance and excel in its environmental performance. Initiatives for voluntary reduction in SO2, SPM, NOx and CO2 emissions are a part of ongoing strategy. The company has carried out Environmental Impact Assessment (EIA) study for all its new projects at following locations: Mundra, Gujarat; Raigad, Maharashtra; Naraj Marthapur, Orissa and Jojobera, Jharkhand.

The Fly ash generated from all thermal power plants is used in ready mix concrete.  Trombay Thermal Power Station has developed an in-house technology in collaboration with TERI for treatment of oily sludge in eco-friendly manner. Some other examples of the key improvements:

• Replacement of Indian coal by imported coal with lower sulphur and lower ash content.
• Improvement to the channel carrying the condenser cooling water discharge.
• Anhydrous Ammonia injection method to control SPM level.
• New FGD for the additional 250 MW capacity that has been set-up at Trombay.
• Maximizing the utilization of gas over other fossil fuels
