To combat soaring energy consumption and address the country’s mounting power demand, the Indian government is set to mandate a minimum temperature of 20°C and a maximum of 28°C for all air conditioners in homes, offices, hotels, and even cars. This sweeping regulation, announced by Union Power Minister Manohar Lal Khattar, marks a first-of-its-kind nationwide standardization of cooling practices; one that could reshape how India stays cool during its blistering summers.
India’s appetite for air conditioning is growing rapidly, with over 100 million AC units already in use and 15 million more added each year. But this comfort comes at a cost: air conditioners account for about 20% of the country’s peak electricity load, consuming around 50 gigawatts of power; equivalent to the output of dozens of large power plants.
The new rule is a direct response to this challenge. By capping the minimum temperature at 20°C, the government aims to:
Reduce energy consumption: Each degree increase in AC temperature can cut energy use by up to 6%, translating into massive savings when applied nationwide.
Ease pressure on the power grid: During peak summer months, when millions crank their ACs down to 16°C or 18°C, the grid faces huge spikes in demand. The new rule could save up to 3 gigawatts of peak electricity use and help avoid costly blackouts.
Promote sustainability: With climate change intensifying heatwaves, the move supports India’s broader push for responsible, sustainable energy use.
The Bureau of Energy Efficiency (BEE) will oversee the rollout, and the government will monitor adherence. While details on enforcement are still emerging, the intent is clear: to make energy-efficient cooling the new normal across India.
Many countries are moving towards similar standards. Japan, for example, recommends 28°C in offices, while the US Department of Energy suggests 25°C–26°C for homes. India’s move is among the most ambitious, covering all sectors—including vehicles.
The regulation is expected to roll out soon, with the government working closely with appliance manufacturers to ensure a smooth transition. As India faces hotter summers and a growing demand for cooling, this bold policy could set a global benchmark for energy efficiency.
