BEE Star Rating equips users to choose the best

Dr Ajay Mathur, Director General, Bureau of Energy Efficiency

Explain the initiatives taken by BEE for improving the standards of motors users in the country?
BEE has introduced a star rating system based on efficiency of the motors. It covers motors up to 375 kW. By introducing the informative star label, BEE gives opportunity to users (manufacturers, consumers) to choose the best efficient motor available in the market.

What is the present level of energy efficiency of electric motors in the Indian industry, compared to global benchmarks?
In the recent past, BEE has not conducted any study for the present level of energy efficiency of electric motors in the Indian Industry. However, as per Indian standard IS 12615, the minimum efficiency for 0.37 kW motor is 72.2% approximately and varies with capacity of motor.

What are the segments in which Indian manufacturers are adopting global benchmarks in technologies and in which sectors we are lagging?
Indian manufacturers are adopting global benchmarks in Air conditioning, and heating, in consumer appliance segments.

What are the benefits that may accrue to the country if the best standards are adopted in toto?
Indian manufacturers may compete with other countries. Best standard adoption would bring more energy efficiency for motors in the country. In the recent past, BEE has not conducted any study to estimate energy savings due to improvement in motor efficiency.

Are there any drawbacks of the unorganised sector (medium- and small-scale manufacturers) when it comes to ensuring energy efficiency and adherence to global standards?
Drawbacks are only for manufacturers who are in unorganized sectors, they may not meet global standard due to lack of testing facilities, manufacturing infrastructure and insufficient funds for technology up gradation.

In addition, many consumers prefer a low cost (low- efficiency) motor as compared to a high cost (higher efficiency) motor despite the lower electricity cost of the higher efficiency motor during its life time.

Also, the very large number of motor manufacturers makes it very difficult to police whether all manufacturers are adhering to high- efficiency standards.
