India's industrial sector is a significant consumer of energy, and its growing demand for cooling power presents both opportunities and challenges for the nation's energy landscape. The surge in cooling demand is driven by factors such as rising temperatures, increasing industrial activity, and urbanization. Understanding these trends is crucial for forecasting future energy needs and formulating sustainable strategies.

Several factors contribute to the rising cooling power demand in industrial India. Firstly, India has been experiencing increasingly severe and frequent heatwaves in recent years. In March 2025, the country recorded an average monthly temperature of 25.5°C, noticeably higher than the 30-year norm. Western and eastern central India, in particular, faced multiple heatwave days, pushing the national power demand up by 6.9%, significantly above the annual average. These escalating temperatures necessitate enhanced cooling measures across industries to maintain operational efficiency and worker comfort.

Secondly, India's industrial output is on the rise, with the Purchasing Managers' Index (PMI) reaching an eight-month high in March 2025. The manufacturing sector is experiencing a strong recovery, contributing substantially to the nation's power demand. Industrial and commercial users account for nearly 50% of India's power consumption, making their expansion a key driver of energy trends. Increased production in sectors like manufacturing, pharmaceuticals, and food processing requires sophisticated cooling systems for machinery, data centers, and storage facilities.

Thirdly, rapid urbanization is intensifying the demand for cooling. Urban areas are susceptible to the Urban Heat Island (UHI) effect, which exacerbates cooling needs in buildings, industries, and transportation. As more people migrate to cities and urban infrastructure expands, the demand for air conditioning and refrigeration systems will continue to surge. It is estimated that India's cooling sector will grow eightfold by 2038, with AC penetration rising from 8 to 40 percent. This could drive energy consumption to 45 percent of peak power load by 2050, potentially increasing GHG emissions by 90 percent above 2017 levels.

The surge in cooling demand has significant implications for India's power sector. Peak power demand reached 235 GW in March 2025, a 14 GW increase from the previous fiscal year. To meet this demand, power generation rose 8% year-on-year to 161 billion units (BU) in March. Coal-based power generation continues to play a dominant role, accounting for 75% of the total power output. However, renewable energy (RE) sources are also gaining traction, with a 15.4% year-on-year increase, contributing 14% to the energy mix.

Looking ahead, Crisil projects power demand to grow 6.5-7.5% in the first quarter of fiscal year 2026, driven by the India Meteorological Department's forecast of above-normal temperatures during the summer months. This sustained high demand for cooling necessitates strategic interventions to ensure energy security and environmental sustainability.

Addressing the cooling power demand requires a multi-pronged approach. Energy efficiency measures, such as improving building insulation, adopting efficient cooling technologies, and implementing stringent energy standards, can significantly reduce consumption. States like Maharashtra are already taking proactive steps to reduce cooling energy intensity through improved efficiency standards and urban planning that promotes passive cooling.

District Cooling (DC) systems are emerging as a crucial solution for optimizing energy use and reducing emissions. By providing cooling from a central plant, DC systems eliminate the need for individual AC units, leading to significant energy savings. The India Cooling Action Plan (ICAP) and the Bureau of Energy Efficiency's District Cooling Guidelines highlight DC as a key strategy for sustainable cooling.

Furthermore, demand-side management strategies, such as shifting cooling demand to off-peak hours, can help alleviate pressure on the grid during peak periods. Pilot programs are being implemented to explore the potential of demand response mechanisms in reducing peak demand.

In conclusion, the cooling power demand in industrial India is a critical factor shaping the nation's energy future. Rising temperatures, industrial growth, and urbanization are driving this demand, necessitating strategic interventions to ensure sustainable and efficient cooling solutions. By focusing on energy efficiency, adopting innovative technologies like District Cooling, and implementing effective demand-side management strategies, India can meet its growing cooling needs while mitigating environmental impact.
