The paper presents benefits from conscious management of electricity consumption in manufacturing plant. The undertaken activities to reduce the cost of consumed electricity are shown. The work was done in Manufacturing Plant of Research and Development Centre of Electrical Machines Komel in Sosnowiec, Poland. Due to implementation of scheduled usage of large energy consuming receivers (furnaces, heaters and dryers) the change of the tariff on which the energy from the supplying company is bought was changed. The change of tariff and scheduled usage of large energy consumers enabled to reduce the cost of electricity of 20%. The savings were reached without reducing the energy consumption and almost without any capital investments. The next step should be replacing the energy consumers by energy efficient devices.
