The inner light
As one of the nation`s leading energy companies, CESC is committed
to deliver safe and reliable electric service to our customers.
We also understand our responsibilities as a corporate citizen: towards the environment, workers, customers, shareholders, general public and the future generations. To us it means, doing business in a responsible way, one that actively takes into account our diverse constituencies those who affect and are affected by our activities.
CESC is the first thermal power utility in the world to be registered with UNFCCC for Carbon Credits. In fact, today CESC has to its credit, three registered CDM project which reflects our strong commitment to the environment.
We have undertaken several measures to use our skills and resources to make our communities better places to live and work.
Effluent Treatment and Recycling
Effluent quality is monitored and controlled to meet the effluent standards set by the Central and State Pollution control Boards, prior to discharge. A part of the water is reused in the plants.
The ash particles in the exhaust, remnants of the burning coal, get separated from the flue gas when it passes through Electrostatic Precipitators (ESP) and get collected in the hoppers as fly ash. The flue gas are monitored by the stations, recognizes external agencies as well as by the Pollution Control Board.
CESC maintains a mobile laboratory for stack gas and ambient air monitoring, which moves between all the stations to measure and monitor stack gas and ambient air.
Solid Waste Disposal
Dry fly ash is conveyed pneumatically to ash silos from where it is unloaded, after proper moistening, on dumpers for disposal. Fugitive emission is thus controlled. Bottom ash is pumped into de-watering bins in the form of slurry. The water from the slurry is separated by decantation and recycled to form ash slurry. This zero discharge system in handling bottom ash thus gives rise to no effluent at all.
Intensity of noise is measured at regular intervals and records are maintained. Immediate necessary action is taken whenever the level at any place approaches the statutory levels.
Each power station takes special care for developing and maintaining green belt along the boundary as well as in the vacant land within the site.
To keep the power stations clean and arouse competitiveness, awards for best house keeping have been introduced Utilization of Ash.
CESC has an Ash Utilisation Division for implementation of comprehensive ash management plan on global technology search to tackle ash utilization on short, mid-term and long-term basis.
Presently, major usages are for land reclamation, structural land filling and road making by Government and Semi-Government Bodies. Rest is being used by local conventional brick fields and experimental farming.
To strengthen the environmental efforts, implementation of Environment Management System ISO: 14001 has been initiated in Southern Generating Station which will be further extended to other units gradually.
Education & Training
To create awareness and sustain the efforts, training programmes on Pollution Control and Environmental Monitoring in Thermal Power Stations are being conducted regularly for all levels of employees. World Environment Day is also observed in the Generating Stations and participated by all employees, when environment- friendly tree saplings are planted.
