Interactive session on "ESCO financing for High Energy Efficient Motor Driven System"

Energy Efficiency Services Ltd. (EESL) in association with IEEMA & ICAI has conducted an Interactive session on "ESCO financing for High Energy Efficient Motor Driven Systems".

The interactive session was flagged off by an expert’s panel consisting of:

• Mr. Sanjeev Ranjan, MD, International Copper association India,
• Mr. Sandeep Garg, Energy Efficiency Expert from EESL
• Mr. Mayur Karmarkar, Head, Asia, Sustainable Energy, International Copper association
• Mr. Anil Naik, Chairman, Rotating Machine Division, IEEMA
• Mr. Jaspal Singh, Senior Manager, EESL

The program was attended by representatives of various motor manufacturers & Drives manufacturers. The intent of the program is to discuss with the Motor & Drives manufacturers about the way forward in developing business models so that large scale penetration of Energy Efficient Motors can be made possible in various sectors.

Motors are a lifeline of the manufacturing industry in India. However, the penetration of high efficiency motors and premium efficiency motors is low in India. In an effort to address the existing barriers ICAI spokesperson, Mr. Sanjeev Ranjan, MD said, “Through this workshop, ICAI aims to increase awareness on energy efficient motors & to address barriers in the adoption of energy efficient motors and enlightened the motors standards scenario in India. He further added “large scale awareness programs should be developed and put in place to inform industrial and commercial electricity users of the significant savings potentials possible through the use of efficient motor ‐driven systems. These programs should target those responsible for procurement of electric motors and motor driven systems, including operations and maintenance managers, production and plant managers, and company executives and decision makers responsible for overall company policy on energy, carbon and cost reduction.”

Mr Anil Naik, Chairman, Rotating Machines Division, IEEMA, has given special address on the motor market & has emphasised that IS12615: 2011 standard for Energy Efficient Motors should be mandatory defining the minimum efficiency performance standards for energy efficient motors in India as IE2 class of efficiency.

Mr Anil Naik in his special address has also spoken about the Indian Standards, which was first introduced as an exclusive standard for energy efficiency motors in 1989 (IS 12615). Later, the same standard was revised in 2004 with a proactive approach from the motor manufacturers with a view to bringing it in line with the CEMEP agreement of Europe. Upon the introduction of the new IEC standard 60034-30 (2008) for the efficiency classification of induction motors and subsequent regulations based on the same adopted by different countries, the Indian manufacturers, Bureau of Indian Standards (BIS), Bureau of Energy Efficiency (BEE) and other stake holders realized the threat of trade barriers for exports from India and potential influx of inefficient motors into the Indian market.

The global harmonization of efficiency classes and testing methods and access to global markets triggered the Indian motor industry to harmonize its standards with the latest IEC standards. During the annual sectional committee meeting of BIS for rotating machines, the BIS and BEE urged the motor industry to harmonize its standards with IEC with the immediate focus on revising the existing Indian Standard, IS 12615:2004 to make it in line with IEC 60034-30. On the basis of IEC 60034-30 and the performance parameters specified in the existing version of IS 12615: 2004, the revised standard IS 12615:2011 has been finalized and released in august 2011.”

Also he has mentioned, the new IEC 60034-30-1 standard is released globally, the scope of the standard includes motors with 2,4,6,8 poles & upto the range of 1000kW with IE4 efficiency values.

Due to the mandatory regulations in Europe, USA, China and other countries, there is a threat to Indian manufacturers for the exports as this regulation prohibit sale of motors below IE2 class in these countries. Also if India does not have the Minimum efficiency standards of IE2 as recommended in the existing IS12615:2011, the sub-standard motors below IE2 class would be dumped to Indian OEMs thus hampering the energy conservation steps taken under the Energy Conservation Act.

Mr. Mayur Karmarkar, Head, Asia, Sustainable Energy, International Copper association, has highlighted that the energy efficiency opportunity is not only by the energy efficient motors alone but has larger opportunity if Energy efficient motor driven systems (EMDS) is considered. He continued to share the international experiences on Policies & the incentives schemes of motor driven systems implemented in major economies and hence for motor driven systems in India, multi-stakeholder cooperation is the key for the market transformation.

Financial schemes should be developed and applied to encourage adoption and use of best practice motor sizing, management and integration, including the appropriate use of VFDs. These should be targeted at the systems producing the highest benefit, namely for pumps, fans and other applications with variable mechanical loads (where torque increases nearly as the square of the rotational speed of the motor).

In most cases, cost effective savings can also be achieved when VFDs are used for conveyors, hoists, escalators and similar applications (where torque is more or less independent of the motor speed).

We should create awareness across Industrial top management & Project consultants and guide them to adopt the revised standard for energy efficient motors in their technical specifications & further highlighted and addressed the challenges faced by industrial units in adopting the EE motors in day to day application.

Mr Jaspal, from EESL has shared the business model for energy efficient motor driven systems which was supported by extensive interactions with all the Motor & drive manufacturers to formulate the viable Financial business models for implementation in support of EESL for enhancing penetration of Energy Efficient Motors.
