NLMK Group has invested over RUB 25 bn in several dozen large-scale energy efficiency projects since 2000. One particular outcome of such projects was to enable recovery of secondary fuel gases for in-house steam and power generation – the share of secondary energy sources is now 82%.
Optimized turbine generator repair time and improved cooling system operation resulted in a higher share of in-house generation at NLMK Lipetsk, up from 30% in 2000 to 58% in 2018. Over the same period, in-house power generation from by-product gases increased almost 2.5-fold, to 357 MW.
