Annexure - G to Board’s Report
Conservation of energy, technology absorption, foreign
exchange earnings and outgo.
Pursuant to provisions of Section 134(3)(m) of the Companies Act, 2013 read with Rule 8(3) of the Companies
(Accounts) Rules, 2014.
A. CONSERVATION OF ENERGY:
1. Steps taken or impact on conservation of energy:
• Installed Microgrid with additional rooftop solar of 640 kW totaling 932 kW of solar capacity at Maneja.
The Microgrid includes 250kVA of BESS (Battery Energy Storage System).
•
Replaced diesel fueled trucks with battery operated forklifts and reach trucks.
•
Solar streetlights and oven modifications at Halol resulted in energy savings.
• Switched over to PNG (Piped Natural Gas) from HSD (High Speed Diesel) in transformer and instrument
transformer factories resulting in the reduction of CO2 emission approximately by 220T.
• Installation of motion sensors in washrooms and meeting rooms resulted in energy saving by controlling
the operation of lights in day hours.
•
Conventional lights with replaced by LED lights with saving of more than 39,000 kWh/annum.
• In GIS (gas insulated switchgear) factory, conventional and T5 fixtures replaced with energy efficient LED
lights in offices. It has resulted in saving of more than 21,000 kWh. All upcoming infrastructure investment
are planned with installation of LED.
• Maintained power availability of more than 99% in distribution network resulting in reduction in HSD
consumption and energy saving by reducing the reprocess time.
• In GIS factory, installed VFDs in Air handling units to get reliability and efficiency of blowers along with
energy conservation resulting in saving of more than 55,000 kWh.
•
Maintained power factor 0.99 by automatic power factor control panel, thereby getting rebate in energy bill.
• Stabilized voltage in lighting circuits in dry and traction transformer factory by installation of lighting
transformer in plant and office area light fixtures while also saving energy.
•
Installed solar tubes on the factory roof resulting in improving lux level in factory area and saving in energy.
• Installed HVLS (High volume low speed) fans which has resulted in removal of multiple industrial fans with
improved uniform cooling and saving energy of more than 500 kWh/annum.
• Modified capacitor manufacturing process and made energy efficiency improvement in heating system
which resulted saving in energy and process time by occupying less space compared to earlier process.
New heating process consumes 40% less energy.
2. Steps taken by the Company for utilizing alternate sources of energy:
• To achieve fossil free electricity, various steps were taken during the year such as installing solar rooftop
panels, switching electricity contracts to green tariffs, signing Power Purchase Agreements (PPA) for
procuring renew electricity and subscribing to International Renewable Energy Certificates (IRECs). Thus
achieved 100% fossil-free electricity in own operations as part of Sustainability 2030 target of becoming
carbon-neutral.
• Reduced fossil fuel consumption by transitioning to battery operated forklifts, PNG (Piped natural gas) for
operations instead of HSD (High Speed diesel).
•
Increased the capacity of solar installation in Maneja factory from 292 kW to 932 kW.
•
Solar power installation of 600 kW at Doddaballapur factory.
