Case Study for Delhi: a computer based decision support system for energy and environmental planning

Delhi, the capital of India, being a part of the National Capital Region, receives its energy supply primarily from two coal and gas based power stations. Petroleum products are supplied from a nearby refinery. The rapid growth of Delhi has had an adverse impact on the environment as can be seen by the following facts:

Delhi has 2.05 million vehicles, more than the vehicle population of Madras, Bombay and Calcutta together.

The total air pollution load in Delhi is of the order of more than 800 tonnes per day.

At most air quality monitoring stations, particulate concentrations have exceeded standards by more than 25 to 50% on a daily basis.

Delhi will continue its rapid growth of economic activity. Even though a formal decision has been taken to prohibit major industrial activities, growth on the commercial front will continue. The case study will evaluate some of the options that are available to enable Delhi to meet its energy requirements with minimum impact on the environment. The primary objective is to develop an evaluation framework and a computerized decision-support system for urban energy and environmental planning. This model will allow the decision maker to study the impact of alternative strategies on total energy consumption and the resulting emissions. The environmental impacts can be studied at various grid locations.

The specific activities of the study are:
