District heating and cooling March 17, 2021 Except for Karachi, Pakistan has extreme cold and hot weather in the respective seasons. With rising standards among the higher economic classes, comfort requirements are also increasing. In Pakistan, power demand goes down to as low as 8000 MW in the winter and goes up to 25000 MW in the summer. Similarly, other than Karachi, gas demand is doubled or tripled in winters. This has serious implications for infrastructural planning and the economics of supply. What are the reasons for the high gas demand for heating in the winter and high electricity demand for cooling in the summer? District heating and cooling (DHC) can play some role in dealing with this imbalance.
