Indo-German trigeneration project
Project descriptionTitle: Indo-German trigeneration project (Trigen)
Commissioned by: German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB)
Lead executing agency: Ministry of Power, Government of India
Overall term: 2008 to 2014
Air conditioning is a major source of energy consumption in India. The high demand for it is driven by the very hot summers when temperatures can rise to nearly 50 degrees Celsius. Cooling (and heating during winter) is achieved with conventional appliances. While the efficiency of these devices is increasing, their power consumption is still subject to structural constraints and will always be higher than it is for some other technologies, for instance that of ‘trigeneration’.
As India is already the fourth largest power consumer globally and is likely to experience steady annual growth of about six per cent in its aggregate power demand, the opportunities for localised power, cooling and heating systems are set to increase significantly.
The use of energy-efficient trigeneration cooling technologies has increased in India, which is helping to reduce green house gas emissions.
India’s manufacturing and business sector is assessing the feasibility of trigeneration technology, particularly as a means of reducing the expenditure on energy for buildings and increasing energy efficiency, while benefiting from an environmentally friendly and reliable technology.
In cooperation with the Bureau of Energy Efficiency, GIZ has started a demonstration project at the Jai Prakash Narayan Apex Trauma Center, a government hospital. After more than a year of operation, this intervention has clearly shown that trigeneration technology can be deployed effectively and in an economically viable way in an existing hospital building.
Results achieved so far
In 2012, the pilot project was initiated successfully at the Jai Prakash Narayan Apex Trauma Center in New Delhi. A website has since been developed through which to disseminate the resulting information, and to raise awareness of the project.
The ongoing monitoring activities will help produce an estimate of the savings in greenhouse gas emissions resulting from the project.
