Based on assessment carried out in five cities, the Government of India’s focus on this new technology will redefine the energy paradigm in India

The primary energy demand in our country has escalated from about 450 million tons of oil equivalent (toe) in the year 2000 to about 770 million toe by 2012. One may be aware that the tonne of oil equivalent is nothing but a unit of energy which is defined as the amount of energy released by burning one tonne of crude oil. This is expected to surge to a whopping 1250-1500 million toe by 2030 (as estimated in the Integrated Energy Policy Report). Reasoning to this jump in demand may go to a number of factors, most important of which are increasing incomes and economic growth which lead to greater demand for energy services such as lighting, cooking, space cooling, mobility, industrial production, office automation, etc.

Though several initiatives have been adopted by the Government of India to cater to the rising demand of its citizens; from promoting the use of energy efficient appliances to shifting towards renewable and sustainable energy, India still holds significant potential to control this ever-growing energy demand. One possible way to combat this demand is via development of modern district energy systems in cities. Modern district energy systems supply heating and cooling services using technologies and approaches such as combined heat and power (CHP), thermal storage, heat pumps, and decentralised energy. District energy basically creates synergies between the production and supply of heat, cooling, domestic hot water, and electricity, and can be integrated with municipal systems such as power, sanitation, sewage treatment, transport, and waste.
