55 Energy Management We realize that energy management is a journey of continual improvement involving multiple improvement initiatives in operations, investment in energy-efficient equipment, energy monitoring, and making the right choices to integrate renewable electricity. Our Energy policy provides a clear direction to address our energy needs sustainably. We have initiated the implementation of ISO 50001 standard to provide the management system framework and set the foundation for sustaining our efforts. Energy consumption and renewable energy Our energy requirements are met through a mix of renewable and non-renewable sources. The renewable energy component in the total electricity purchased is 31% in the reporting year. Overall, the component of renewable energy in the total energy consumed is 13%. This achievement is building momentum for us as we have met the internal sustainable development goal we had set for ourselves. Consequently, we reduced GHG emissions by 18% as compared to last year’s emissions. This helped us reduce 7976 tCO2e accounting for 15% and 20% reduction in Scope 1 and Scope 2 emissions respectively. Energy Monitoring & Conservation We lay equal emphasis on monitoring energy consumption and involve Services Effectiveness Teams (SET) in addressing energy losses. The IOT based energy management system measures energy usage vis-a-vis the baseline and prompts for action to curb leakages for each production block. We have defined benchmarks for energy consumption in utilities, process equipment and other equipment (like ETP, Multiple effect evaporator, etc) with respect to occupancy. Likewise, we have an SEC key performance indicator target for energy consuming assets included in our monitoring program. We have completed 10 energy conservation projects in our manufacturing facility this year. These projects have generated cumulative energy savings of 1.33 million kWh/annum. In addition, we have completed 70% projects which are identified as Energy kaizens. Pumping Optimization Automation & Trimming Integration of Brine chillers Replacement with Efficient Pump Chiller Improvement By pipeline re-routing Replacement with Efficient ETP blower Pump Swapping With small pump Integration of ETP Blower Savings: 1.33 Million kWh/ annum Energy savings Being energy smart We are investing in a battery of energy conservation projects with a dedicated focus by our energy managers. An important project in utilities enabled us to integrate two chillers and operate it with an optimum load while the capacity utilization was reduced in either of the production blocks the chillers are independently mapped to. Chiller Utility Integration Before • Individual two utility +5 chiller are running for two production block facilities • Both chillers are running at partial loading based on its occupancy • Constant primary flow system After • Integration of both utilities • Flow balancing carried out by converting from constant primary to variable primary with flow control logic • Actual saving > 300 kwh/day
