Globally, Industrial sector is known to be the largest electricity consumer, 70% of which is contributed by electric motor systems alone. In India, about 40% of the total electricity consumption is contributed by the industrial sector. Electric motor-systems use 28% of total national electricity which is reasonably high.
Historically, the motors sold (and used by end-users) in India have lower energy efficiencies (IE-1 or less) than the efficient products technologically available and manufactured. Based on estimation, 90- 95% of the current installed stock of motors is at IE1 & sub-IE1 levels. The issue of multiple rewinding in the service life of motor(s) further reduces the efficiency drastically. This results in more energy consumption, hence affects the competitiveness of any business entity.
Further, Department of Industrial Policy & Promotion (DIPP) has issued a Quality Control order requiring all imported and domestically manufactured motors to conform minimum IE2 class of efficiency as per the revised IS:12615 with effect from 01.01.2018. It is a great opportunity for the motor users to leap frog to the readily available even higher technology like IE3 class of motors.
The NMRP is a first of its kind effort at a national scale. EESL aims to create an infrastructure to accelerate adoption for Higher Efficient Motors Specifically IE3 efficiency class through innovative financing business model & awareness creation. Under this program we are offering IE3 motors ranging from 1HP to 100 HP to the Indian Industries. This program is advantageous for MSME as well as non-MSME industries. EESL is offering Upfront/PMC and EQI/ESCO business modalities to the end users. Our Suppliers are: CG Power, ABB, Siemens and Bharat Bijlee Limited. Till date 5,280 IE3 motors have been deployed in the industry.
The National Motors Replacement Programme (NMRP) shall offer appropriate technical specifications (as per IS-12615) keeping in mind key customer pain points viz. high initial costs, high operating and maintenance costs and quality of the products.
EESL is targeting the 3-phase LT induction motors in the capacity range of 0.75 kW to 75 kW preferably directly-coupled with loads like pumps, fans, blowers, air compressors etc.

EESL Model # 1: PMC Model / Supply Contract
In the Project Management Consultancy (PMC) model, the user shall bear the product cost whereas EESL provides the PMC support to the users. The PMC support includes the following:
Finalization of the scheme for replacement: Number of motors to be replaced, technical specifications, estimation of energy saving, investment requirement etc.
Procurement of Motors: Through open competitive bidding
Supply of Motors at User Site: Facilitation/Management of supply of motors at the user site with due co-ordination with the supplier
Warranty Obligation: Ensuring the warranty obligation with the supplier
Update in National Motor Dashboard: Estimated Energy Saving and other benefits to be reflected in a national dashboard
Payment Terms: The user shall be liable to pay the entire project cost post-delivery of motors within mutually agreed time frame (typically within 30 days)
EESL Model # 2: ESCO Model / Shared Saving Model
In this model, the entire upfront investment will be done by EESL in addition to the PMC activities as described above. Here, the project cost will therefore be material cost-plus PMC fees plus the finance cost for timeline mutually agreed by user and EESL. Here, repayment to EESL by the user will be done through Equated Quarterly Instalments (EQIs) for three-year period. For this modality client has to submit the payment security (BG/LC) to EESL.
It is observed that the repayment amount to EESL by the end-user is about 50-70% of the monetized savings accruing through the improvement in efficiency of the motor.
