Producing one ton of steel in an electric arc furnace requires about 400 kWh per short ton (1.44 gigajoules) or about 440 kWh per ton (1.6 GJ); the theoretical minimum energy required to melt one ton of scrap is 300 kWh (1.09 GJ) (melting point 1,520 °C (2,768 °F)). Thus, a 300-ton, 300-MVA EAF woul
