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.
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.
