Abstract: India is facing significant power shortage and has embarked upon a large generation capacity augmentation program encompassing different technologies both conventional and renewable. According to Central Electricity Authority (CEA), India’s installed capacity was 170.2 GW on 31st January 2010, and the power shortage varied between 11% and 16%. In a country like India, which faces acute power shortage, promoting energy efficiency measures is a key to overcoming energy shortage. Trigeneration can be seen as a promising technology for Indian building industry, especially for buildings having simultaneous demand for power, warm water and chilled air requirement. This work captures a wide spectrum of technological details, market assessment studies and regulatory and policy framework for promoting Trigeneration technology. A study of “TRIGEN†initiative at Jai Prakash Narayan Apex Trauma Center (JPNATC), All India Institute of Medical Sciences (AIIMS) - a pilot project implemented by German Development Cooperation (GIZ) and Bureau of energy efficiency (BEE) was also conducted.
The study demonstrates the huge potential that exists for Trigeneration technology in India. If Trigeneration were to be implemented in all four & five star hotels and multi-specialty hospitals across India, the amount of energy saved would be substantial enough to reduce India’s power deficit by 3-4%. The analysis showed that hotel and hospital industry should be targeted and with the successful implementation of project at JPNATC, AIIMS the reliability and learning in this technology would only increase. The trigeneration system at JPNATC has been designed for part load and is not designed to meet the complete demand. The potential avenues for GIZ involvement were explored for supporting pilot transaction using Trigeneration technology. The work also mentions the gaps that exist in proliferation of this technology and some recommendations are also made to overcome it. This work also encompasses some case studies, which are promising examples of this technology.
