VISION

To supply reliable, efficient and sustainable power for Hindustan Zinc with zero harm and at lowest cost.

Power Capacity Mix in FY 2019-20

(MW)

RENEWABLE POWER BUSINESS

Investments in green energy enables us to reduce our carbon footprint on a sustainable basis.

In FY 2019-20, 0.7 MW of rooftop solar energy was commissioned, increasing the total solar power capacity to 39.64 MW. In addition, there is the Waste Heat Recovery Boilers (WHRB) capacity of 35.37 MW. Our wind energy plants are under long-term power purchase agreement with distribution companies.

During the year, we produced solar power of 79.38 mn units, waste heat energy of 146.24 mn units and wind power of 449.29 mn units, leading to a reduction of 5,80,995 MT of CO2 through green power.

FY 2019-20: PERFORMANCE SNAPSHOT

SAFETY INITIATIVES IMPLEMENTED IN THE YEAR

• Turbine enclosure in all three locations to separate hot and oil circuit, leading to reduction of fire hazards
• Wagon wheel clamper in the coal-handling plant wagon tippler area to reduce man-machine interaction
• Proximity switch in coal yard vehicle and locomotives across Hindustan Zinc CPP to reduce man-machine and machine-machine interactions
• Installed belt tear switch in all conveyors at Dariba and Zawar CPP for safe conveyor operation

THERMAL POWER BUSINESS

The coal-based thermal power plants generated 3,880 mn units in FY 2019-20, compared to 3,961 mn units in FY 2018-19. Higher power purchase from grid and lower metal production led to decline in power production. Overall, the specific coal consumption remained flattish at 444 gms/kWH in FY 2019-20 compared to 440 gms/kWH in FY 2018-19.

During the year, revamping of thermal power units was initiated with the aim of increasing the name plate capacity from 80 MW to 91.5 MW per unit in FY 2020-21. This will lead to higher power generation from each unit with the same quantity of steam leading to cost savings and also reduction in GHG emissions.
