How it works?
![Page 6: Technology details, potential and experiences of Trigeneration C Vijayakumar The Energy and Resources Institute Bangalore Workshop on ‘Innovative and Sustainable](https://reader036.vdocuments.us/reader036/viewer/2022062718/56649ead5503460f94bb4de1/html5/thumbnails/6.jpg)
Energy Utilisation in Generator
![Page 7: Technology details, potential and experiences of Trigeneration C Vijayakumar The Energy and Resources Institute Bangalore Workshop on ‘Innovative and Sustainable](https://reader036.vdocuments.us/reader036/viewer/2022062718/56649ead5503460f94bb4de1/html5/thumbnails/7.jpg)
Efficiency• Generator – 35 – 40%• Co-generation system – 50 – 70%• Tri-generation system – 80 – 90%
![Page 8: Technology details, potential and experiences of Trigeneration C Vijayakumar The Energy and Resources Institute Bangalore Workshop on ‘Innovative and Sustainable](https://reader036.vdocuments.us/reader036/viewer/2022062718/56649ead5503460f94bb4de1/html5/thumbnails/8.jpg)
Why Trigeneration?
• Trigeneration systems supply energy in three forms:
•Electricity, Heat, Chilled water
• Higher combined efficiency (85% - 90%)
• Savings on fuel and energy costs
• Reduction in T & D losses

Why Trigeneration?
![Page 10: Technology details, potential and experiences of Trigeneration C Vijayakumar The Energy and Resources Institute Bangalore Workshop on ‘Innovative and Sustainable](https://reader036.vdocuments.us/reader036/viewer/2022062718/56649ead5503460f94bb4de1/html5/thumbnails/10.jpg)
Why Trigeneration?
• Reduction in GHG emission (About 30 - 50%)
• Lower electrical usage during peak summer demand
• No harmful chemical pollutants since water is used as
the refrigerant in chiller
• Increased power reliability
• Back-up power to the site
