Monchegorsk — Kola MMC (Nornickel’s subsidiary) has analysed the results of its energy efficiency programme (roadmap) for 2017 and calculated the aggregate economic effect at RUB 113 m — a significant improvement against the previous year.
In total, Monchegorsk and Polar Division production sites saw the implementation of 49 initiatives aimed at the efficient use and consumption of energy resources. These initiatives made it possible to reduce the consumption of thermal energy by 10 thousand Gcal, water from all sources by 4,176 thousand cu m, electricity by more than 9,172 thousand kWh, compressed air by 223,837 thousand cu m, and heating oil by 6,488 tonnes.
Energy efficiency projects were carried out at a number of Kola MMC production facilities. The revised hours of converter operation at the smelting shop helped minimise the work of blowers and save over 218 thousand cu m of process air, or more than RUB 18 m. The tank-house optimised the consumption of recycled water, saving RUB 4.37 m. The power and energy supply shop streamlined the compressed air feed for production processes, which reduced electricity costs by over RUB 10 m.
In 2018, Nornickel will continue implementing the energy efficiency programme at Kola MMC.
