Energy efficiency
Nornickel’s major production assets are located beyond the Arctic Circle where the winter lasts eight months a year. It is therefore critical for the Group to ensure reliable and high-quality power supply to its enterprises and population in the regions where it operates.

In 2017, the Company implemented a number of organisational arrangements and upgrades of its key power equipment as part of the Energy Saving and Energy Efficiency Programme.
These initiatives helped achieve savings of 100,116 tonnes of reference fuel (units) for CHPPs, 44.867 mln kWh of electricity for internal needs and 177,732 Gcal of heat against the targets.
In 2017, per unit fuel consumption at CHPPs decreased to 281.4 g/kWh, down by 13.9 g/kWh against the annual budget targets, 27.7 g/kWh vs 2016 and 9.7 g/kWh vs 2015.
Gas producers saved 17.574 mln cubic meters of natural gas in 2017 by cutting gas consumption for own technological needs and reducing technological losses during transportation.
The Company also generates electric power from renewable energy sources at NTEK’s Ust-Khantayskaya and Kureyskaya HPPs (installed capacity of 441 MW and 600 MW, respectively).
In 2017, the share of renewable energy stood at 38% for Nornickel and 44% for its Polar Division.
In 2018–2020, the Company will continue to renovate and upgrade the main power equipment and transmission devices along with waste water treatment systems.
