Captive Power Plant

Performance Overview

Our Power business is driven by the Vision “to supply reliable, efficient and sustainable power for Hindustan Zinc with ZERO harm and at lowest cost.” Led by our strong Sustainability focus, we are continually investing in strengthening our Green Energy business to reduce Greenhouse Gas emission and carbon footprint. At the same time, we are focused on revamping our Thermal plants to boost operational excellence. Collectively, these initiatives are enabling us to drive exceptional improvement in our CPP performance on all major parameters of sustainable growth.

GREEN POWER

Our Renewable Power business encompasses Solar Power, Waste Heat Energy and Wind Power. During FY2021, we had a cumulative green power capacity of 349.19 MW, which included 273.5 MW of wind power, 40.42 MW solar power for captive consumption and 35.27 MW captive capacity of waste heat energy. All our wind and solar power projects are now registered under the Gold Standard, which is globally the most rigorous certification for carbon offset projects. Due to this, the Company generated a revenue of ₹ 8.34 crore from the sale of Carbon Credits, significantly higher than last year.

Reducing the carbon footprint – the way forward

With sustainability an overarching objective of our business strategy, we remain committed to continuous expansion of our Green Energy footprint. We are moving proactively forward towards achieving our goal to reduce our carbon footprint by 5,00,000 ton of CO2 through a series of innovative initiatives. These include:

  • Installation of 20 MW solar power project at Dariba
  • Commissioning of 35.27 MW Waste Heat Recovery Boiler (WHRB) at Fumer project
  • Installation of 5.58 MW WHRB at Dariba
  • Sifting of Mines Material from underground to surface by Winder, in place of heavy machinery
  • Installation of Variable Frequency Drives to reduce auxiliary power consumption
  • Upgradation of roof-top solar power plant at Head Office, Udaipur, from 100KW to 200KW
  • Revamping of all five unit turbines of CPP
  • Use of Electrical HEMM vehicles in underground mines in place of HSD-based HEMM
CONVENTIONAL POWER

Thermal Power Business

102.5%

Best Utilization factor achieved by Hindustan Zinc CPP in FY2021

Our six coal-based thermal power plants have a cumulative power generation capacity of 485.5 MW. In FY2021, Hindustan Zinc CPP generated 4,085 Mn units of power which was 3.73% more than the previous Financial Year.

Hindustan Zinc CPP achieved its lowest Specific Coal Consumption of 439 Gms/kWh in last seven years. Also achieved lowest ever Auxiliary Power consumption of 7.99% in FY2021.

Our power business showed remarkable progress during the year due its operational excellence despite the pandemic. Chanderiya & Dariba CPP achieved their best plant load factor. Our Zawar CPP achieved best ever Specific Coal Consumption (428 Gms/kWh) and Auxiliary Power Consumption (7.54%). Further, Hindustan Zinc WHRB STG achieved its best ever generation at 203.13 mn units.

Scaling Safety, Reliability & Operational Efficiency

In tandem with our ZERO Harm policy, we initiated several new sustainability measures at our CPPs during the year, with the explicit aim of ensuring increased safety, reliability and efficiency of operations.

Safety Initiatives
  • Establishment of remote control room for smooth plant operation/safe shutdown of plant in case of any COVID-like situation in control room
  • Weighted CO2 Flooding System for generator at Chanderiya CPP
  • Installation of automated Pneumatic doors at bottom ash inspection door to avoid fire injury and to avoid the line of fire at all three CPPs
Reliability & Efficiency Initiatives
  • Commissioning of 1 MW Solar Power Project at Kayad Mine
  • Gold standard registration of all Renewable Power Projects
  • Successful completion of injury-free Turbine revamping of Zawar Unit #4
  • Waiver of charges through advocacy, resulting in financial saving of ₹ 1.3 crore per month from July 2020 onwards
  • Single CWP (Cooling Water Pump) operation at Chanderiya CPP and at Zawar CPP, enabling Power Saving of 0.6 MU in Q3 of FY2021
  • Commission of Pilot project on FGD by Gore Technology to reduce Sulphur Oxide (SOx) emissions at Zawar
