1 INDUSTRIAL VISIT TATA THERMAL POWER PLANT PROJECT MANAGEMENT BATCH ( ) On the, the DEPARTMENT of Project Management, National Institute of Industrial Engineering organized an industrial visit in order to integrate experiential learning of class room inputs with industry to study there processes, systems, challenges faced by the organization with real-time situations which will be a great input for growth as project managers. Within the isndustry premises Mr. Gautam Sumedha took charge and had taken the group to the plant around noon and briefed up with the introduction about the plant as well as its operations. Tata Power generates about 9100 MW of power of which 7285 MW is from Thermal Power plant. The Company has been associated with the growing legacy of Mumbai as a business city for over nine decades.tata Power, India s largest integrated private power company, was bestowed the prestigious 'Vasundhara Award' in the industry category by Maharashtra Pollution Control Board (MPCB) It has an installed capacity of 1580 MW. It has following generating units: 150 MW Oil (unit 1 to unit 4). 500 MW Coal (unit 5). 500 MW running on oil (unit 6, this is being converted to run on coal). 180 MW Gas based (unit 7) 250 MW Coal (unit 8). The first 4 units have been decommissioned and are no more functional. Tata Power is consistently working towards innovating and implementing eco-friendly technologies, and undertaking various projects under the Clean Development Mechanism, including wind power projects and various small-scale energy efficiency projects. Tata Power's power plant emissions are well within the norms laid down by the National Ambient Air Quality Standards.Committed to complying with all regulations pertaining to the preservation and enrichment of the environment, Tata Power uses world-class innovative and environment friendly technologies. Trombay Thermal Power Station provides power to the city of Mumbai At present 2377 MW is embedded generation for Mumbai Presently, peak power demand of Mumbai City is about 3391 MW Demand is expected to increase to 6200 MW by 2020 Unit 6 needs to be operated at full capacity to meet the growing demand

2 High price of low sulphur oil results in very high cost of generation in Unit 6 High price of low sulphur oil results in very high cost of generation in Unit # 6 Natural gas is not likely to be available for next 10 years RLNG prices are very high and volatile Modernization of Unit 6 on coal will ensure cheap power to Mumbai Embedded generation to be maintained at Trombay for success of islanding scheme Low ash low Sulphur coal and modernization Use of Imported coal having low sulphur (0.28%) and low ash (4.5%) Multi fuel firing capability will be retained No change in the capacity of Unit 6 (500 MW) No additional land acquisition required No additional water allocation required No additional discharge of waste water Reduction in pollution load due to installation of ESP and FGD Noise abatement by use of acoustic barriers, robust structural designs No additional power evacuation required Shortest gestation period Incremental capex for modernization Augmentation of existing captive coal berth from 2.4 to 4.4 Million MT/Annum Closed pipe conveyors for transportation of coal from coal berth to plant Installation of stacker reclaimer and screw unloader at Coal Berth/ storage Installation of State-of-the Art high efficiency NOx burners Installation of high efficiency ESP for PM control 100% ash utilization from day one Benefits of Unit6 Reduction in transmission congestion Lower tariff to Mumbai consumers on account of reduced cost of generation Ensuring uninterrupted and reliable power supply to consumers of Mumbai

3 Ensuring islanding capability for Mumbai To meet demand supply gap for Mumbai Impact due to Fly Ash movement Parameters No. of Bulkers Per day Carrying capacity of bulkers (MT) Negligible increase in the transportation of fly ash after modernization project Negligible increase in the transportation of fly ash after modernization project About 18 months time will be required for migration from 15 to 28 tonner bulkers for fly ash transportation Demand for the fly ash in RMC from various vendors in FY 12 was 630 MT/day as against our generation of 200 MT/day This will ensure 100% fly ash utilization in RMC from day one High efficiency Electrostatic Precipitator is provided to ensure particulate matter emission below 50 mg/ Nm 3 FGD to treat 100% flue gas will be installed to limit SO 2 emission below 24TPD as per present consent condition Installation of low NOx burners Air Quality Management Coal transportation through closed pipe conveyor Stacker reclaimer and screw unloader Green area development around coal berth and coal yard to further reduce fugitive dust emission Acoustic barriers will be provided at high noise generating sources like pumps, blowers, turbine room, etc. to maintain noise levels within permissible limit Robust structural design for machineries to bring down noise level Personal Protective Equipments will be provided to the workers working in high noise areas. All the machines were lubricated to reduce noise transmission Regular training and awareness will be given to the employee and contractors about the noise management Regular health check up of the people working in high noise area will be carried out

4 Use of low ash imported coal will be continued Existing & additional fly ash will be utilized in RMC to achieve 100% fly ash utilization Fly ash will be pneumatically conveyed to the silos Fly ash will be stored in close silos to avoid any dust emission Transportation of fly ash will be carried out only through closed bulkers Solid Waste Management (Bricks out of bottom ash) Message Box ( Arial, Font size 18 Bold) Unit # 6 Modernisation by change of fuel 23 Bottom ash will be stored in hydro bins and will be utilised for brick making and other purposes Capacity of the existing brick making plant will be enhanced (4000 bricks/ day, 10 MT/ day bottom ash) to increase utilization of bottom ash for brick making One more brick making plant will be installed for consumption of bottom ash in brick making Existing Fly Ash Management System Existing Captive Coal Berth facility
