Resumen
Electricity stands as the main energy used for lead-acid battery (LAB) manufacturing. This study introduces
an energy management methodology to address the electricity consumption in lead-acid
battery plants, improving efficiency standards. The “equivalent battery production” is introduced to
define the energy performance criteria to be met in the different production sections of the battery plant.
The methodology combines the guidelines of the ISO 50001 standard with the energy management
framework for manufacturing plants. The result is a structured approach for detecting inefficiencies and
pinpointing their sources.
The management methodology was implemented during 2016. In the formation area 222MWh were
saved during 2016. This saving accounts for 3.9% less electricity than forecasted by the energy baseline of
the area. Additionally, the emission of some 40 tCO2.eq. associated with the generation of the electricity
production were saved. Moreover, at plant level 424MWh were saved, which account for 3.6% less
electricity than forecasted by the energy baseline of the plant. In total, around 76 tCO2.eq. were saved as a
result of the electricity savings in the plant.
