NLMK Lipetsk continues to upgrade its lighting systems in production facilities and office buildings. The project will reduce electricity consumption while increasing the lighting level; in 2017 these efforts will save more than RUB 7.5 million. The pilot project to replace ceiling lights was launched in 2011. 33,000 highly efficient state-of-the-art energy saving lights with a high luminous efficacy were installed. The capex amounted to about RUB 300 million. As a result consumption of electricity was reduced by more than 100 million kW*h per year. Payback period estimated at 2.2 years.
