India to Cap AC Temperatures at 20°C: How The New Rule Will Save Billion Of Units
The Indian government is set to enforce new regulations standardizing air conditioner (AC) temperature settings, restricting cooling below 20°C and heating above 28°C. Union Minister for Housing and Urban Affairs Manohar Lal Khattar announced the move, calling it a pioneering step toward energy efficiency.
Small Adjustments, Big Savings
According to the 2018 statement by the Bureau of Energy Efficiency (BEE), raising an AC's temperature by just 1°C can reduce electricity consumption by 6%. Many users set their units at 20-21°C, but the ideal comfort range is 24-25°C. Shifting from 20°C to 24°C could lower power bills by 24%.
If widely adopted, this practice could save 20 billion units of electricity annually-worth ₹10,000 crore. Even if half of all users adjust their settings, it would still conserve 10 billion units and cut 8.2 million tonnes of carbon dioxide emissions each year.
Why the 20°C Limit?
The rule aims to ease strain on India's power grid, particularly during peak summer demand.
Speaking to Bloomberg, Pankaj Agarwal, a senior official in the power ministry, noted that ACs consume 50 gigawatts (GW)-about 20% of the country's peak load.
"Studies show that every 1°C increase in AC temperature cuts energy use by 6%. That means if everyone sets their ACs just 1 degree higher, we can save about 3 gigawatts of power during peak times," Agarwal told Bloomberg.
With 100 million ACs in use and 15 million new units added yearly, minor tweaks could yield massive energy savings. A University of California, Berkeley study estimates that stricter efficiency norms could prevent 60 GW of peak demand by 2035, avoiding ₹7.5 trillion ($88 billion) in new power infrastructure costs.
Record Power Demand & Grid Stability
India's electricity consumption hit 250 GW last summer and may reach 270 GW this year. While May's rains temporarily lowered demand, June's heatwaves have pushed usage back up, with a recent peak of 241 GW.
"Even if the peak requirement reaches the estimated 270 gigawatts, we are fully prepared to meet it," said Khattar. Standardizing AC temperatures will help stabilize the grid and reduce blackout risks.
Renewable Energy Push
Alongside AC regulations, the government is expanding renewable energy and storage solutions to ensure sustainable power supply. The move aligns with India's broader goals of reducing emissions and optimizing energy use.
Countries with Standardised Air Conditioner (AC) Temperature Settings
| Country | Standard/Rule Type | Temperature Limit(s) | Scope/Enforcement |
|---|---|---|---|
| Japan | Government recommendation | 28°C (summer, offices) | Advisory, supported by campaigns |
| Spain | Legislation (public/commercial) | ≥27°C (cooling) | Mandatory for public/commercial |
| China | Government regulation | ≥26°C (government buildings) | Mandatory, with penalties |
| Italy | Government regulation | ≥25°C (public buildings) | Mandatory for public buildings |
| Belgium | Government regulation | Specific rules for public buildings | Mandatory for public buildings |
| United States | Energy Star recommendation | 25.5°C (78°F, when occupied) | Advisory, incentivized |
| Australia | Efficiency standards (MEPS) | No national temperature mandate | Advisory comfort guidelines (22-24°C) |
Final Takeaway: A slight adjustment in AC settings can lead to significant savings-both for your wallet and the nation's power infrastructure. Will this new rule change how you use your AC?
