A workshop on Trigeneration technology was organised by FICCI in New Delhi recently with support of the Bureau of Energy Efficiency (BEE), Energy Efficiency Services Limited (EESL), Indo German Energy Forum (IGEF), Germany’s international technical cooperation organisation GIZ and German development bank KfW. It focused on enhancing energy efficiency by combining multiple energy supplies into a single module and thus minimizing the inefficiencies due to thermal and other conversion losses.
Trigeneration technology is the simultaneous production of electricity, heat and cooling. In a tropical country like India, air- conditioning is a major energy guzzler. Present cooling technologies are predominantly based on compression chillers which are driven by electricity from the grid. Due to losses in power generation and transmission, only 25 percent of the primary energy used in a coal fired power plant reaches the end user.
In comparison, a cogeneration or ‘Trigeneration’ system at the end user’s site can reach overall efficiencies of 80 percent, as it can utilize the waste heat from power generation to cover the heating and cooling demand of the facility. Moreover, there are no transmission losses.
The most promising areas of Trigeneration application include hospitals, hotels, departmental stores, data centres, industries, and so on. Overall it is estimated that there are several thousand potential sites in India where Trigeneration could be applied economically.
