Rationalization of electricity use in wood industry plants

Electricity in wood industry plants is mainly used for electromagnetic and light effects and to a lower extent for thermal and chemical effects. This paper elaborates the electricity effects most frequently used in the plants. The ways of rationalization of electricity consumption are particularly analysed in terms of electrical lighting and electric-motor drive as the main points of consumption. The manner of electricity calculation is analysed in accordance with the applicable tariff system of the Republic of Croatia in effect since 1st September 2002. Thus the analyses has been carried out of three plants with the share of the electricity price of 3 %, 5 % and 10 % in the price of end products. By calculation of energy consumption pursuant to the applicable tariff model in three different wood industry plants, the prices of HRK 0.47, HRK 0.58 and HRK 0.64 have been obtained for 1 kWh of electricity. In order to provide good management and rationalization of electricity consumption it is necessary to observe and understand some basic regularities
