5. Technologies
• Steam cycle facilities
• Gas turbines
• Cogeneration and combined cycle facility
• Internal combustion
7. Issues
• Maintenance and operating costs are high
• Long time required for erection and putting
into action
• A large quantity of water is required
• Great difficulty experienced in coal handling
• Presence of troubles due to smoke and heat
in the plant
• Unavailability of good quality coal
8. Issues
• Maximum of heat energy lost
• Problem of ash removal
• Thermal efficiency is just about 45%
• Clearances from Ministry of Environment and
Forests
• Land acquisition
• Site accidents due to process hazards, bad
plant designs, technical errors, inadequate
training of personnel employed
• Coal shortage
9. Recommendations
• Informed decision making
• Clear procedures and standards for
environmental aspects
• Make energy auditing compulsory to ensure
optimal power utilization
• Natural air flow and other low power
demand utilities to beat the power needs
• Ancillary industries to be set up near thermal
power plants
