Apex industry body Indian Electrical & Electronics Manufacturers’ Association (IEEMA) has proposed that the government should introduce a formal policy for scrapping of energy-inefficient motors.
Addressing a virtual media conference ahead of “ELROMA 2021,” being organized by IEEMA, senior members of the event’s organizing committee, said that such a scrapping policy would eventually make a significant contribution towards the nation’s energy saving drive.
Though India, since January 2018, has stipulated the use of motors with a minimum efficiency of IE-2 standard, motors of IE-1 or lower grade are still in use. Anil Naik, Former Chairman of IEEMA’s Rotating Machines Division, and member of the ELROMA 2021 Committee, confirmed that India is producing motors that are of IE-2 or grade or higher, only. However, considering the average lifespan of a motor to be 15 years, there are still some 3-4 million motors of IE-1 or lower grade currently in operation.
With a view to discouraging the use of inefficient motors, IEEMA has been approaching agencies like Bureau of Energy Efficiency (BEE) and The Energy Research Institute (TERI) to initiate work on a scrapping policy requiring that motors of IE-1 or lower grade be scrapped after their useful life period, say 15 years, Naik noted.
Potential saving
n his opening remarks, Ashok Kulkarni, Chairman, ELROMA 2021, explained that India annually produces around 2 million motors, across various ratings, with an aggregate capacity of 35 GW. There is potential saving of 600 mw, every year, through the use of energy-efficient motors. He also remarked that apart from efficient motors, there is scope for ushering in energy efficiency through better system integration of motors.
Kulkarni observed that even before energy efficiency standards for motors were officially put in place, IEEMA member organizations voluntarily opted for energy-efficient motors, thereby taking energy-saving measures proactively.
ELROMA 2021 is the tenth edition of IEEMA’s series of technical conferences on rotating machines. The event, being held digitally, will be conducted between September 6 and September 8, 2021. ELROMA 2021, covering electrical rotating machines (motors) and drives, will run on the theme “Smart Efficient Rotating Machines & Control Solutions for a Greener World.”
Awareness campaigns
Though the government has officially not yet stepped in the effort of scrapping of inefficient motors (IE-1 grade), IEEMA has been conducting awareness campaigns to encourage users to switch to IE-2 (or higher) grade of motors. The saving on energy and costs is very significant. For instance, replacing a 5HP continuously-running motor with an IE-2 or IE-3 grade motor, will have a payback period of less than a year. It is estimated that of the total ownership cost of a motor during its useful life period, only 5 per cent represents the initial purchase cost while the remaining 95 per cent is the running (electricity) cost.
Anil Naik said that through IEEMA has not yet formally approached any Central government agency for the IE-1 motor scrapping policy, the industry body has raised this issue on various industry forums, including those organized by Confederation of Indian Industry (CII).
Naik was of the view that large Indian business conglomerates, which are conscious of issues like green energy and energy conservation, must take the lead and shun the use of inefficient motors in their own organizations. This could set a healthy precedent for smaller companies to follow. Speaking of awareness drives conducted by IEEMA, Naik recalled the case of a textile cluster in Surat, Gujarat, where over 3 lakh motors of IE-1 or lower grade were in use. Thanks to the awareness campaigns organized by IEEMA, so far around 5,000 such motors have been replaced by IE-3 or IE-4 motors.

Moving to IE-3 and higher standards
According to Dr Praveen Vijayraghavan, Chairman, Technical Committee, IEEMA, India is fully equipped to manufacture energy efficient motors, domestically. Today, nearly 30 per cent of motors produced in India are of IE-3 grade, and India was equipped to even supply IE-4 motors globally. In fact, it is independently learnt that the first IE-5 grade motor (a line starter motor) was domestically produced in India, before anywhere else in the world.
Domestic production of IE-3, IE-4 or IE-5 is not therefore the core issue. There is also no dearth of demand for energy-efficient motors. The primary concern here is the resistance towards replacing existing motors, which are inefficient but in operation nevertheless. “We are very reluctant to replace anything that is working fine,” was how Dr. Vijayraghavan, summarized the psyche of a typical Indian consumer.
Curtailing imports
It is estimated that India annually imports nearly Rs.1,500 crore worth of LT and HT motors. Taking other smaller motors –those used in appliances and gadgets, etc – the total import of motors is in the region of Rs.2,500 crore per year. As against this, direct export of motors from India is only around Rs.500 crore. Another Rs.500-600 crore worth of exports is of the “deemed” category, where motors are exported as components of larger electrical equipment.
Based on India’s domestic competency and global competitiveness in the field of rotating machines, IEEMA clearly sees the opportunity of reducing imports by around Rs.1,000 crore per year and boosting exports by the same quantum. There was therefore clear scope to save foreign exchange worth Rs.2,000 crore annually, felt Ashok Kulkarni, Chairman, ELROMA 2021.
