Context:
District cooling systems are emerging as a sustainable solution to rising cooling demand in Indian cities, helping reduce electricity consumption and emissions while supporting climate-resilient urban planning.
Key Highlights:
- Technology and Infrastructure
- District cooling involves a centralised plant producing chilled water distributed through insulated pipelines to multiple buildings.
- Eliminates the need for individual air-conditioning systems.
- Efficiency Benefits
- Can reduce electricity consumption for cooling by 30–50%.
- Reduces peak electricity demand by 20–30%.
- Environmental Impact
- Cuts greenhouse gas emissions by 15–40%.
- Reduces refrigerant use by up to 80%.
- Helps mitigate the urban heat island effect.
- Implementation Example
- GIFT City (Gujarat) has implemented district cooling, potentially reducing power demand by about 6,100 MW.
Relevant Prelims Points:
- District Cooling
- Centralised cooling system supplying chilled water to buildings via pipelines.
- Thermal Storage
- Technology that stores cooling energy during off-peak hours for later use.
- Urban Heat Island Effect
- Phenomenon where urban areas become significantly warmer than surrounding rural areas due to dense infrastructure and human activity.
- National Cooling Action Plan (NCAP)
- Government initiative aimed at reducing cooling demand, improving energy efficiency, and lowering emissions.
Relevant Mains Points:
- Growing Cooling Demand in India
- Rising temperatures, urbanisation, and heatwaves are increasing demand for cooling infrastructure.
- Energy and Climate Benefits
- Reduces electricity demand and carbon emissions.
- Enhances energy security by lowering peak load pressures.
- Urban Planning Implications
- Best suited for dense commercial and institutional zones such as:
- Airports
- Hospitals
- IT parks
- Universities.
- Way Forward
- Integrate district cooling systems into smart city planning.
- Establish clear regulatory frameworks for implementation.
- Promote public-private partnerships and financing models.
