NLMK Group, an international steel company with facilities in Russia, the USA and the EU, generated savings of RUB 700 million in 2015 through optimization of energy procurement; and process and auxiliary equipment performance.
A total of 344 initiatives aimed at boosting energy management efficiency were implemented last year. The aim of these initiatives was to increase in-house energy generation and recovery of waste energy; to upgrade lighting systems at Group companies; to reduce vapour and hot water supply system energy losses; and to reduce equipment downtime.
Large projects included the launch of a 20 MW top-pressure recovery turbine (TRT) for Blast Furnace #7 at the Lipetsk site and air separation unit #17. Among other benefits, these projects increased Novolipetsk’s self-sufficiency in energy from 54% to 57%. Almost 77% of all in-house energy was generated through the recovery of by-product BF and coke gases.
Sergey Chebotarev, NLMK Group Vice President for Energy, said:
“In order to reach the level of best available technologies, in 2015 NLMK Group implemented a set of investment projects and a significant number of cost-efficient optimization initiatives. Key projects in the pipeline include the construction of a TRT for blast furnace #6; improved reliability of the energy supply to BOF shops; replacement of turbogenerator #5; completion of upgrades to bell-type furnaces at Novolipetsk rolling operations; and establishing the energy supply for the Stoilensky pelletizing plant currently under construction.”
Initiatives to boost energy efficiency resulted in a 1% year-on-year improvement in the energy intensity of Novolipetsk products during 2015, to reach 5.66 Gcal per tonne of steel. NLMK Group companies use the level of best available technologies (BAT) as their energy efficiency target. For companies with a similar production chain to NLMK, BAT energy intensity is 5.1 Gcal per tonne of steel. Almost all of the main NLMK Group facilities improved their energy intensity: Stoilensky (from 0.074 to 0.070 Gcal/t), Altai-Koks (from 7.79 to 7.64 Gcal/t), VIZ-Steel (from 8.06 to 7.22 Gcal/t), NLMK Kaluga (from 0.85 to 0.79 Gcal/t.
NLMK Group’s energy management efficiency during 2015 was endorsed by international specialists. Representatives of the British Standards Institute (BSI) confirmed the compliance of the energy management system at Altai-Koks, Stoilensky, VIZ-Steel, NSMMZ, NLMK Metalware, and Novolipetsk with the requirements of the ISO 50001 international standard. Stagdok, Dolomit and NLMK Kaluga also successfully passed their energy management efficiency audits in 2015. Currently, all of the main NLMK Group Russian facilities have valid certificates of compliance with the requirements of the ISO 50001 international standard. This is the result of the Company’s consistent approach to the generation, consumption and use of energy for the production of goods.
