In 2017-18, India’s national electricity consumption reached 1,130.2 terawatt-hours (TWh), with the industrial sector consuming a substantial 41.48%, equivalent to about 468.8 TWh. Motors and motor-driven systems for about 69% of industrial electricity consumption.

The NMRP focuses on the replacement of outdated motors (often sub-IE1) with IE3-rated motors. The program operates under two main business models:

• Supply Contract/Project Management Consultancy (PMC) Model: the industrial user bears the full cost of the motor replacement. EESL provides project management support, including the estimation of baseline energy consumption, finalization of motor specifications, procurement through transparent bidding and coordination of delivery.
• Shared Saving, ESCO Model: EESL covers the initial investment, including motor procurement and installation, while the user repays EESL through a shared-savings arrangement. Repayments are typically set at 50-70% of the savings achieved.

• Energy Savings: 9,150 megawatt-hours (MWh)
• Cost Savings: $902,112 USD
• CO2 Emissions Reduction: 8,050 tonnes

Do you think the NMRP is adequately designed to address the barriers hindering motor replacement in industry? Which of the 2 business models could be more successful in your opinion?

The ETL features products such as boilers, electric motors, air conditioning and refrigeration equipment.

The list functions as an easy-to-use procurement tool for energy managers, procurement professionals, facilities managers and a wide variety of other professions and organisations. The ETL gives the added reassurance to purchasers of measured and verified energy performance.

The Department for Business, Energy and Industrial Strategy (BEIS) annually reviews the technologies and products that qualify for inclusion. The ETL is managed on behalf of BEIS by the Carbon Trust and ICF.

A full list of the technology categories currently on the ETL can be found below:

• air-to-air energy recovery
• automatic Monitoring and Targeting (aM&T) equipment
• boiler equipment
• combined heat and power (CHP)
• compressed air equipment
• heat pumps
• heating, ventilation and air-conditioning (HVAC) equipment
• high speed hand air dryers
• lighting
• motors and drives
• pipework insulation
• radiant and warm air heaters
• refrigeration equipment
• solar thermal systems and collectors
• uninterruptible power supplies
• waste heat to electricity conversion equipment

The full list of products under the motors and drives category is available at: https://etl.energysecurity.gov.uk/products/motors-drives-fans

In the case of motors, the List provides information such as name and contact of the manufacturer, type of motor, technical parameters (rated power, # of poles, operating voltage) and presence of a VSD.

The standards adopted in 2023 follow the ones published in 2014, where DOE prescribed MEPS for electric motors manufactured on and after June 1, 2016.

The latest standards apply to single speed induction motors (with cage operating at 60Hz sinusoidal line power), NEMA design A/B/C or IEC design N/H motors, manufactured or imported into the US starting on June 1, 2027. The nominal full-load efficiency for each motor power is reported in the table below.

DOE analyses suggest that implementing energy conservation standards for electric motors would result in substantial energy savings. Over the anticipated 30-year period starting from the year of compliance (2027–2056), these standards are projected to energy savings of 880 TWh* compared to a scenario without new standards.

The newly adopted standards for electric motors are also expected to bring significant environmental advantages. DOE estimates indicate that these standards will lead to cumulative reductions in emissions over the same period, including 91.69 million tons of CO2, 35.12 thousand tons of SO2, 148.74 thousand tons of nitrogen oxides (NOx), 690.10 thousand tons of methane, 0.82 thousand tons of nitrous oxide (N2O), and 0.23 tons of mercury. Specifically, the estimated reduction in CO2 emissions through 2030 is 0.90 million tons, equivalent to the yearly electricity consumption of over 150 thousands households.

*This value refers to full-fuel-cycle (“FFC”) energy savings. FFC energy savings includes the energy consumed in extracting, processing, and transporting primary fuels ( i.e., coal, natural gas, petroleum fuels).
