Did you know that Mahindra & Mahindra was the first company in the world to commit to EP 100 towards carbon neutrality by 2040? EP 100 is a global initiative to double energy productivity and is led by an international non-profit Company Climate Group that brought together over 120 energy smart businesses. Mahindra and Mahindra are also the first Indian Company to commit and declare a carbon price of USD 10 per ton of carbon emissions. In this blog, we share Mahindra and Mahindra’s success story in achieving a 94% increase in Energy efficiency in Automobile sector and 87% in Farm Sector. This is in comparison to 2009 and aligns with our commitment - EP 100 by 2030 and 60% by 2026.

One of the main areas of high energy consumption was in material handling. Evaluation of consumption patterns revealed that motor and blowers were contributing ~ 60% of energy consumption in automobile manufacturing industry, while blowers (including air handling unit) and air circulators combined contributed over 40%.

Achieving lower energy consumption and increased air flow was not possible in the conventional air handling equipment. Feasibility studies were undertaken for two options. One possibility was to replace conventional Air handling equipment with high energy efficient options. Alternative, cutting edge technologies could be leveraged to modify existing setup. Feasibility report revealed high potential for positive results in the second option.

Initiatives undertaken

Intelligent EC blower BLDC Motors and HVLS Air Circulators

  • Conventional high energy consuming blowers were replaced with Intelligent EC (Electronically computed) blowers in Air handling unit applications for paint shop and HVAC applications.
  • Conventional Air circulators were replaced with BLDC (Brushless direct current) Motors and HVLS (High Volume Low Speed) Air circulators at shop floor.

    • Outcome:

  • The replacement of conventional blower with EC blower helped to increase motor efficiency from 75% to 95%.
  • Energy consumption halved resulting in savings more than 50%.
  • Belt drive losses were brought down to Zero from 7%.
  • Drive losses were brought down from 3 % to Zero.
  • System efficiency improved from 45% to 75%.
  • The installation of BLDC Motors and HVLS Air circulators resulted in savings of more than 35%.
  • Process parameter controls reduced consumption of energy.

    • Impact:

  • Energy consumption and Energy cost reduction by appx 40%. Overall estimated cost saving is Rs 1.2 Crs/annum
  • Contributed to tCO2 1260 with a carbon reduction potential of 2800t CO2 per annum.
  • Equivalent to annual electricity consumption of 267 Houses per annum.
  • Carbon mitigation/savings equivalent to 32,300 trees.
  • Improved airflow, better control over process parameters and maintenance free equipment.

    • Other Initiatives that have contributed towards EP100 include:

  • Hybrid solar system for air conditioning system.
  • Improving energy efficiency through VFD’s, interlockings, automations and digitization.
  • Replacement of old motors with premium efficiency IE3 motors.
  • Waste heat recovery from air compressors and paint shops.
  • Installation of Energy efficient inverter split AC’s.
  • Adoption of innovative Nano-technology at pre-treatment to reduce process temperature.
  • Replacement of all conventional lightings with LEDs.
